Osteoporotic Hip Fracture: How We Make Better Results?
Byung-Chan Choi, Kyung-Jae Lee
J Korean Fract Soc 2024;37(1):52-59.   Published online January 31, 2024
DOI: https://doi.org/10.12671/jkfs.2024.37.1.52
AbstractAbstract PDF
The prevalence of osteoporosis and incidence of osteoporotic fractures is increasing gradually as life expectancy is prolonged and the aged population increases. Osteoporotic hip fractures (femoral neck fractures and femoral intertrochanteric fractures) have high mortality because the patients with these fractures are elderly and have several comorbidities. Thorough preparation and a multidisciplinary approach in the preoperative period are critical, and early surgery is recommended. There are also several principles to treat osteoporotic hip fractures and prevent fixation failures. Many studies have suggested various treatment methods for femoral neck fractures and femoral intertrochanteric fractures. Functional recovery treatment is essential based on the patient’s health and activity levels. Finally, aggressive management of osteoporosis and the prevention of falling is needed to treat osteoporotic hip fractures successfully.

Risk Factors of Fixation Failure in Femoral Neck Fractures
Sung Hyun Yoon, Kyu Beom Kim, Hyung Jun Lee, Kyung Wook Kim
J Korean Fract Soc 2023;36(4):118-124.   Published online October 31, 2023
DOI: https://doi.org/10.12671/jkfs.2023.36.4.118
AbstractAbstract PDF
Purpose
Internal fixation after a femoral neck fracture (FNF) is one of the conventional treatment options for the young and active elderly patients. However, fixation failure of internal fixation is a probable complication. The treatment of fixation failure after a primary internal fixation of the FNF remains a challenge.
Materials and Methods
Between July 2002 and March 2017, 83 patients who underwent internal fixation after FNF were retrospectively analyzed. Radiological assessments, including Pauwels’ angle, fracture level, reduction quality, and bone union, were measured, preoperatively and postoperatively. Moreover, intraoperative variables such as time to surgery, surgical time, and estimated blood loss were also evaluated.
Results
The patients were divided into the fixation failure and the non-failure groups. Among the 83 patients, 17 cases (20.5%) of fixation failure after the primary internal fixation of the FNF were identi-fied. When comparing the two groups according to the radiographic data, Pauwels’ angle and the reduction quality based on Garden’s angle showed significant differences (p<0.001). Moreover, when comparing the intraoperative variables, unlike the surgical time and estimated blood loss, significant differences were noted in the time interval from injury to surgery and specifically in whether the surgery was performed within 12 hours after injury (p<0.001).
Conclusion
Pauwels’ angle, reduction quality, and time to surgery are the major factors that can predict the possibility of internal fixation failure of the FNF. Early and accurate anatomical reduction is needed to decrease complications after the internal fixation of the FNF.

Comparison of Clinical Outcomes for Femoral Neck System and Cannulated Compression Screws in the Treatment of Femoral Neck Fracture
Jae Kwang Hwang, KiWon Lee, Dong-Kyo Seo, Joo-Yul Bae, Myeong-Geun Song, Hansuk Choi
J Korean Fract Soc 2023;36(3):77-84.   Published online July 31, 2023
DOI: https://doi.org/10.12671/jkfs.2023.36.3.77
AbstractAbstract PDF
Purpose
This study compared the clinical and radiological results of the femoral neck system (FNS) and cannulated compression screws (CCS) for the fixation of femoral neck fractures.
Materials and Methods
Patients who underwent FNS or CCS internal fixation for femoral neck fractures between January 2016 and January 2022 were analyzed retrospectively. The hip joint function using the Harris hip score (HHS) was evaluated three months and one year after surgery. The operation time, fracture healing time, and associated surgical complications in the two groups were compared and analyzed statistically.
Results
Seventy-nine patients were categorized into 38 FNS and 41 CCS groups. The FNS group had a longer operation time and higher postoperative HHS at three months (p<0.01). Femoral neck shortening was lower in the FNS group (p=0.022). There were no significant differences in the fracture healing time and other complications.
Conclusion
There were no differences in most clinical outcomes and complications between the two groups except for the three-month HHS and femoral neck shortening. This study suggests that FNS could be an alternative to CCS for treating femoral neck fractures.

Computational Simulation of Femoral Neck System and Additional Cannulated Screws Fixation for Unstable Femoral Neck Fractures and the Biomechanical Features for Clinical Applications
Ju-Yeong Kim
J Korean Fract Soc 2023;36(1):1-9.   Published online January 31, 2023
DOI: https://doi.org/10.12671/jkfs.2023.36.1.1
AbstractAbstract PDF
Purpose
To identify the biomechanical features for clinical applications through a computational simulation of the fixation of the Femoral Neck System (FNS) with additional cannulated screws for a Pauwels type III femoral neck fractures.
Materials and Methods
Thirty cadaveric femurs underwent computed tomography, and the images were transferred to the Mimics ® program, resulting in three-dimensional proximal femur models. A three-dimensional scan of the FNS and 6.5 mm and 7.0 mm cannulated screws was performed to enable computerized virtual fixation of FNS with additional cannulated screws for unstable femoral neck fractures. Furthermore, the cannulated screw used for additional fixation was modeled and used as a cylinder within the Ansys program. The biomechanical characteristics of these models were investigated by applying a physiological load virtually.
Results
The maximum von Mises stress value at bone was 380.14 MPa in FNS and 297.87 MPa in FNS+7.0 mm full-thread cannulated screw. The maximum von Mises stress value at FNS was 786.83 MPa in FNS and 435.62 MPa in FNS+7.0 mm full-thread cannulated screw. The FNS group showed the highest maximum von Mises stress values at bone and FNS. For total deformation, the maximum deformation value was 10.0420 mm in FNS and 9.2769 mm in FNS+7.0 mm full-thread cannulated screws. The FNS group represented the highest maximum deformation compared to the other groups.
Conclusion
Considering the anatomical spatiality and biomechanical characteristics of the FNS in unstable femoral neck fractures, when one 7.0 mm full thread cannulated screw was also fixed to the anterosuperior portion of the FNS, significant biomechanical stability was demonstrated.

Mortality-Related Risk Factors in Total Hip Arthroplasty for Femoral Neck Fractures in Elderly Patients
Jae Sung Suh, Hyung Gon Ryu, Young Ju Roh, Dae Won Shin
J Korean Fract Soc 2022;35(2):51-56.   Published online April 30, 2022
DOI: https://doi.org/10.12671/jkfs.2022.35.2.51
AbstractAbstract PDF
Purpose
Total hip arthroplasty (THA) using dual mobility components (DMC) is a reasonable surgical option for displaced femoral neck fractures in elderly patients, resulting in lower dislocation rates and improved stability. The purpose of this study was to investigate the clinical outcomes and risk factors responsible for mortality in elderly patients who were diagnosed with a displaced femoral neck fracture and had undergone DMC-THA.
Materials and Methods
Out of 147 cases of THA from December 2018 to June 2020, a total of 79 cases were enrolled in this study, with the following characteristics: (1) Garden stage III or IV, (2) over 75 years of age, and (3) over 1 year of follow-up. All the patients received DMC-THA surgery using the anterolateral approach.
Results
The mean follow-up period was 15.0±8.43 months and a total of one dislocation case was observed. The mortality rate was 17.7% (14/79), and it was especially higher in patients with a past medical history of malignancy (odds ratio [OR]=7.18, p=0.03) or a cognitive disorder such as dementia (OR=5.48, p=0.03). Preoperative low initial hemoglobin levels (OR=0.65, p=0.04) and low UCLA (Uni-versity of California at Los Angeles) score (OR=0.47, p=0.02) were also associated with mortality.
Conclusion
When considering THA as a treatment approach in elderly patients with a displaced femoral neck fracture, a high mortality rate is expected in patients with low preoperative hemoglobin levels or a history of malignancy or cognitive disorders. Hence, thorough monitoring and management should be undertaken before and after surgery.

Pediatric Femoral Neck Fracture
Joo Hyung Han, Hoon Park
J Korean Fract Soc 2021;34(1):34-43.   Published online January 31, 2021
DOI: https://doi.org/10.12671/jkfs.2021.34.1.34
AbstractAbstract PDF
Pediatric femoral neck fracture is an uncommon injury with a high complication rate, regardless of the appropriate diagnosis and management. The bony anatomy and blood supply of the proximal femur in a skeletally immature patient differ from those in adult patients. Generally, these fractures result from high-energy trauma, but pathologic hip fractures also occur, usually from low-energy trauma. Pediatric femoral neck fractures are categorized using the Delbet classification system. This classification guides management and aids clinicians in determining the risk of avascular osteonecrosis. The ideal surgical treatment is determined by the fracture type and the age of the patient. Reduction, which is achieved using a closed or open procedure, combined with stable fixation and/or cast immobilization, is recommended for most of these fractures. Anatomical reduction within 24 hours from the injury may result in a good surgical outcome. Although the effects of capsular decompression after reduction and fixation have not been established, decompression is easy to perform and may reduce the risk of avascular necrosis. Despite appropriate management, osteonecrosis can occur after all types of pediatric femur neck fractures. Other complications include coxa vara, nonunion, and premature physeal arrest.

Case Report
Rare Experience of Bilateral Femoral Neck and Shaft Fractures - A Case Report -
DaeHyun Choe, Jae-Ho Lee, Ki-Chul Park
J Korean Fract Soc 2020;33(3):154-158.   Published online July 31, 2020
DOI: https://doi.org/10.12671/jkfs.2020.33.3.154
AbstractAbstract PDF
Ipsilateral fractures of the femoral neck and shaft are relatively common injuries and accompany 2% to 9% of all femoral shaft fractures. On the other hand, it is extremely rare for these injuries to occur bilaterally. This paper reports the authors’ experience of a case with bilateral femoral neck and shaft fractures. The patient sustained multiple injuries, including liver laceration with hemoperitoneum, bilateral open fractures of the tibia, and bilateral femoral neck, and shaft fractures caused by a high-speed motor vehicle accident. Under the circumstances, damage-control orthopedic principles were applied, and external fixators were initially placed. After the patient’s general condition showed improvement, both femurs were fixed with a reconstruction nail. Fracture healing was achieved without complications, such as avascular necrosis of the femoral head. Despite the rare occurrence, this paper describes this case because these injuries must be managed with meticulous attention.

Computational Simulation of Multiple Cannulated Screw Fixation for Femoral Neck Fractures and the Anatomic Features for Clinical Applications
Jin Hoon Jeong, Gu Hee Jung
J Korean Fract Soc 2018;31(2):37-44.   Published online April 30, 2018
DOI: https://doi.org/10.12671/jkfs.2018.31.2.37
AbstractAbstract PDF
PURPOSE
To identify the anatomic features for clinical applications through a computational simulation of the fixation of three cannulated screws for a femoral neck fracture.
MATERIALS AND METHODS
Thirty cadaveric femurs underwent computed tomography and the images were transferred to the Mimics® program, resulting in three-dimensional proximal femur models. A three-dimensional scan of the 7.0 mm cannulated screw was performed to enable computerized virtual fixation of multiple cannulated screws for femoral neck fractures. After positioning the screws definitively for cortical support, the intraosseous position of the cannulated screws was evaluated in the anteroposterior image and axial image direction.
RESULTS
Three cannulated screws located at the each ideal site showed an array of tilted triangles with anterior screw attachment and the shortest spacing between posterior and central screws. The central screw located at the lower side was placed in the mid-height of the lesser trochanter and slightly posterior, and directed toward the junction of femoral head and neck to achieve medial cortical support. All the posterior screws were limited in height by the trochanteric fossa and were located below the vastus ridge, but the anterior screws were located higher than the vastus ridge in 10 cases. To obtain the maximum spacing of the anterior and posterior screws on the axial plane, they should be positioned parallel to the cervical region nearest the cortical bone at a height not exceeding the vastus ridge.
CONCLUSION
The position of cannulated screws for cortical support were irregular triangular arrangements with the anterosuperior apex. The position of the ideal central screw in the anteroposterior view was at the mid-height of the lesser trochanter toward the junction of the femoral head and neck, and the anterior and posterior screws were parallel to the neck with a maximal spread just inferior to the vastus ridge.

Jae Hak Jung, Kwan Hee Lee, Yong Ju Kim, Woo Jin Lee, Sung Hyun Choi
J Korean Fract Soc 2012;25(4):317-322.   Published online October 31, 2012
DOI: https://doi.org/10.12671/jkfs.2012.25.4.317
AbstractAbstract PDF
PURPOSE
To evaluate the radiologic and clinical results of percutaneous transverse fixation with K-wires for 5th metacarpal neck fracture.
MATERIALS AND METHODS
Between January 2007 and September 2010, 18 patients with a 5th metacarpal neck fracture, who underwent operative treatment, were included in this study. The surgical method was percutaneous transverse fixation using K-wires. We evaluated fracture angulation in oblique radiographs preoperatively, postoperatively, and at final follow-up, and used SPSS to perform statistical analysis. We also performed clinical evaluation using the Disabilities of the Arm, Shoulder and Hand (DASH) score.
RESULTS
All of the 18 cases were completely united, and in the oblique radiographs, the angulation was corrected from 50.69degrees to 11.68degrees. The average difference between postoperative and final follow-up angulations was 0.14degrees, which was statistically insignificant. Clinically, the DASH score was 1.030 and no complications were observed.
CONCLUSION
Percutaneous transverse fixation using K-wires could be one of the best ways to treat a 5th metacarpal neck fracture because of its simple method and low rate of complications.

DOI: https://doi.org/10.12671/jkfs.2011.24.1.67
AbstractAbstract PDF
PURPOSE
To evaluate radiological and clinical results of the antegrade intramedullary prebent K-wire fixation for the 5th metacarpal neck fracture.
MATERIALS AND METHODS
Between January, 2006 and December, 2009, 31 patients with displaced neck fracture of the fifth metacarpal who received antegrade intramedullary prebent K-wire fixation were included in this study. Radiological and clinical outcome evaluations were performed.
RESULTS
All the fractures were completely united. In the oblique radiographs, the average of preoperative angulation was corrected from 38.9degrees to 4.4degrees. The average difference between postoperative and final follow-up was 1.2degrees. Clinical outcomes were satisfactory except for one patient who had sustained ulnar nerve dorsal branch injury during surgery.
CONCLUSION
Antegrade intramedullary prebent K-wire fixation may be preferentially considered as one of the best ways to fix the displaced neck fractures of the fifth metacarpal.

Comparison of Bone Mineral Density in Elderly Patients over 65 Years according to Presence and Types of Hip Fracture
Myung Ho Kim, Moon Jib Yoo, Joong Bae Seo, Hyun Yul Yoo, Sang Young Moon
J Korean Fract Soc 2010;23(3):263-269.   Published online July 31, 2010
DOI: https://doi.org/10.12671/jkfs.2010.23.3.263
AbstractAbstract PDF
PURPOSE
We measured the BMD of elderly patients with osteoporotic hip fracture in order to understand the relationship between BMD of each sites and hip fracture occurrence or the types, and also to suggest a reference point for starting an osteoporosis treatment program.
MATERIALS AND METHODS
From July 2007 to February 2010, we investigated total 147 elderly osteoporotic hip fracture patients over 65 years. For control group, 80 patients who were over 65-year-old and did not have any fracture were selected. BMD was compared at each site between each groups statistically.
RESULTS
In the comparison of femur intertrochanter and neck fracture groups, BMD of femur neck and trochanter areas and L2, L3 areas were significantly less in intertrochanteric fracture group. In the analysis according to the classification of intertrochanteric fracture, BMD of intertrochanter and Ward's triangle area were significantly less in unstable fracture group than stable one. Each of the fracture threshold of intertrochanteric and neck fracture group was -1.10 and -1.36 of the T-score in proximal femur, and -1.40 and -1.40 of the T-score in lumbar vertebrae.
CONCLUSION
To examine the BMD of both proximal femur and lumbar vertebrae areas is helpful to predict the hip fracture occurrence and the type of hip fracture. And for the prevention of hip fracture in elderly patients over 65 years, we propose that the aggressive treatment of osteoporosis should be started to prevent fracture for patients with a T-score less than -1.40.

Tae Ho Kim, Jong Oh Kim, Sung Sik Kang
J Korean Fract Soc 2009;22(2):79-84.   Published online April 30, 2009
DOI: https://doi.org/10.12671/jkfs.2009.22.2.79
AbstractAbstract PDF
PURPOSE
To evaluate the factors predicting complications after internal fixation using multiple cannulated screws in the patients with femoral neck fracture, the authors performed a comparative study of a success group and a failure group and reviewed the literature.
MATERIALS AND METHODS
Sixty-eight patients with intracapsular femoral neck fractures were treated by multiple pinning from January 2000 to July 2007 and followed up more than one year. Relationships between the complications such as failure of union, collapse of femoral head due to osteonecrosis of femoral head and several affecting factors including the degree of displacement by Garden stage, state of reduction, position of screws, patient's age, time interval from injury to operation, anatomical fracture site and two weeks postoperative (99m)Tc-MDP bone scan were analyzed.
RESULTS
Statistically significant factors were the degree of displacement by Garden stage (p<0.001), reduction state (p<0.001) and postoperative two weeks (99m)Tc-MDP bone scan (p<0.001).
CONCLUSION
An accurate anatomical reduction is needed to decrease complications with multiple cannulated screws fixation of femoral neck fracture. Displacement of fracture by Garden stage and (99m)Tc-MDP bone scan are major factors predicting complications.

AbstractAbstract PDF
PURPOSE
To evaluate the clinical results of bipolar hemiarthroplasty in elderly patients more than 65 years of age with a femoral neck fracture.
MATERIALS AND METHODS
Forty-six bipolar hemiarthroplasties in 43 patients more than 65 years of age which could be followed more than 3 years were included in this study. The clinical outcomes were evaluated using Harris hip score, pain score and support score. The radiological results were analyzed by femoral stem loosening and bipolar cup migration.
RESULTS
The average Harris hip score was 88.7 (62~96) points. An excellent score was recorded in 34 cases, good in 7 cases, fair in 3 cases and poor in 2 cases. The average pain score was 39.3 points and there were no pain in 20 cases, slight pain in 17 cases, mild pain in 6 cases and moderate pain in 2 cases. The average support score was 9.6 points and 32 patients could walk without the use of any assistive devices. Two cases were converted to total hip arthroplasty due to femoral stem loosening with or without bipolar cup migration.
CONCLUSION
For the early ambulation and functional recovery of elderly patients with femoral neck fracture, bipolar hemiarthroplasty was considered as one of recommendable methods.

DOI: https://doi.org/10.12671/jkfs.2007.20.1.64
AbstractAbstract PDF
PURPOSE
To evaluate radiologic and clinical results of bouquet pin intramedullary nail technique for the 5th metacarpal neck fracture.
MATERIALS AND METHODS
Between April, 2005 and February, 2006, 17 patients treated by bouquet pin intramedullary nail technique for the 5th metacarpal neck fracture were evaluated. All patients were reviewed clinically and radiologically after operation.
RESULTS
All of 17 cases of fractures were completely united. In the anteroposterior radiographs, the average of preoperative angulation was corrected from 34.4° to 5.2°. Also, in the oblique radiographs, radiographic results of angulation correction were satisfactory which was corrected from 44.2° to 11.7°. Although, the averages of difference between postoperative and final follow-up angulations were 1.5° in the anteroposterior radiographs and 0.9° in the oblique radiographs, they were not statistically different. All patients were excellent clinically except 1 patient who has moderate joint stiffness after operation.
CONCLUSION
Selecting of appropriate patients who is indicated, bouquet pin intramedullary nail technique for the 5th metacarpal neck fracture could be a good treatment method without complications.

Hyun Dae Shin, Kyung Cheon Kim, Se Min Woo, Yong Bum Joo, Dong Kyu Kim
J Korean Fract Soc 2006;19(4):449-453.   Published online October 31, 2006
DOI: https://doi.org/10.12671/jkfs.2006.19.4.449
AbstractAbstract
PURPOSE
To evaluate the results of treatment according to the sub-classification of the Mason type II fracture.
MATERIALS AND METHODS
From 1999 to 2003, according to the sub-classification of the Mason type II fracture, 33 patients were treated with miniplate in displaced neck fracture (IIa), with compression screw in displaced head fracture (IIb), with miniplate and/or compression screw in displaced head and neck fracture (IIc), with compression screw and miniplate in comminution fracture (III) or excision of head in irreducible state. The clinical results were evaluated by An and Morrey's functional rating index.
RESULTS
Functional rate score averaged 92.7 in type IIa, 88.4 in IIb, 86.4 in IIc, 83.5 in type III with reduced fracture, 75.0 in type III with excised head, and 75.5 in type IV. Complications included heterotopic ossification (2 cases), metal loosening (1 case), malunion (1 case), partial ankylosis of elbow (3 cases), posttraumatic arthritis (1 case).
CONCLUSION
These results supported the recommendation for internal fixation with compression screw in isolated radial head fracture (IIb) and with miniplate in fracuture combined with displaced neck (IIa, IIc, indicated some III). We concluded that sub-classification is useful for dicision making in radial head or neck fracture's treatment.

Analysis of Affecting Factors of Fixation Failure of Femoral Neck Fractures Using Internal Fixation
Soo Jae Yim, Seung Han Woo, Min Young Kim, Jong Seok Park, Eung Ha Kim, Yoo Sung Seo, Byung Il Lee
J Korean Fract Soc 2006;19(3):297-302.   Published online July 31, 2006
DOI: https://doi.org/10.12671/jkfs.2006.19.3.297
AbstractAbstract
PURPOSE
To evaluate the factors which influence on the fixation failure after internal fixation using multiple cannulated screws in the patients with femoral neck fracture.
MATERIALS AND METHODS
Ninty-six patients (male: 63, female: 33) who underwent closed reduction and internal fixation of femoral neck fracture between Feb. 1994 and Jun. 2002 with use of multiple cannulated screws. The mean age was 68 years (17~90) and mean follow-up period was average 50 months (36 months~6 years). The fixation failure was defined by change in fracture position above 10 mm, change in each screws position above 5%, backing above 20 mm, or perforation of the head, respectively. They were evaluated with the age, gender, fracture type, accuracy of reduction, placement of screws, posterior comminution and also studied the risk factors which influenced nonunion and the development of avascular necrosis.
RESULTS
Twenty-four patients out of 96 patients had radiographic signs of fixation failure. The incidence of nonunion in the fixation failure group was 41% (10/24) and AVN was 33% (8/24). There were statistically significant correlations between fixation failure and nonunion and that posterior comminution, poor reduction and improper placement of the screws were the major factors contributing to nonunion.
CONCLUSION
In case of femoral neck fracture of internal fixation using multiple cannulated screws, posterior comminution, poor reduction and improper placement of the screws were the major factors contributing to nonunion and fixation failure.

Young Jin Seo, Soon eok Kwon, Jun Dong Chang
J Korean Fract Soc 2005;18(3):227-231.   Published online July 31, 2005
DOI: https://doi.org/10.12671/jkfs.2005.18.3.227
AbstractAbstract PDF
PURPOSE
To evaluate the availability of bone scan as a preoperative study by analyzing patients who developed ipsilateral femoral neck fractures during intramedullary nailing for femoral shaft fractures.
MATERIALS AND METHODS
Among 28 patients who conducted preoperative bone scan before performing intramedullary nailing for femoral shaft fractures, three patients developed femoral neck fractures during the operation. We analyzed retrospectively the result of bone scan including clinical and radiological findings of three patients.
RESULTS
Among 28 patients, 7 showed hot uptake in femoral neck area compared to the unaffected side in preoperative bone scan; All 3 patients who developed femoral neck fractures during the operaion showed hot uptakein the area. Among 7 patients who showed hot uptake, there were no abnormalities in plain radiograph and computerized tomography of femoral neck area.
CONCLUSION
The risk of femoral neck fracture should be considered during the intramedullary nailing for femoral shaft fracture, if there was hot uptake in femoral neck area in preoperative bone scan.

Hyung Ku Yoon, Byung Kuk Kim, Dong Eun Shin, Sang Jun Song, Hyung Kun Park, Ji Hoon Chang
J Korean Fract Soc 2005;18(2):126-130.   Published online April 30, 2005
DOI: https://doi.org/10.12671/jkfs.2005.18.2.126
AbstractAbstract PDF
PURPOSE
To evaluate clinical outcome and functional result after cemented bipolar hemiarthroplasty of displaced neck fracture in parkinsonism patients.
MATERIALS AND METHODS
12 parkinsonism patients treated by cemented bipolar hemiarthroplasty of displaced femur neck fracture from August 1994 to October 2002 were evaluated. Posterolateral approach was performed. Preoperative and postoperative walking ability, activity of daily life and severity of parkinsonism were compared. The effects of parkinsonism on clinical outcome were analyzed retrospectively.
RESULTS
The median difference of walking ability was 1 (p=0.001) and that of ADL scale was -3 (p=0.0005). There was no significant change in the severity of parkinsonism (p=0.5), and the severity and duration of parkinsonism were not correlated with postoperative functional status. 7 cases of voiding difficulty, 5 of temporary delirium, and 2 of temporary respiratory insufficiency were noted as general complications. 2 cases of dislocation and 1 of infection were noted as orthopaedic complications.
CONCLUSION
In parkinsonism patient, walking ability was worsened, activity was more independent, but severity of parkinsonism was not changed after hemiarthroplasty of displaced femur neck fracture. Orthopaedic surgeons should bear in mind that functional outcome is poor and orthopaedic complication rate high in parkinsonism.

AbstractAbstract PDF
PURPOSE
To evaluate the functional changes, postop delirium and complications after cemented bipolar hemiarthroplasty for the femur neck fractures in patients aged around ninety.
MATERIALS AND METHODS
Between May 1995 and April 2002, of the twenty seven patients, 17 who follow-up for at least one year were included in this study. Walking ability, activity of daily living, mental status, chronic illness, postoperative delirium and complications were evaluated retrospectively using Yoon's walking class, ADL scale, MMSE-K score, ASA classification, DSM IV respectively.
RESULTS
The walking ability was decreased to 2.4 from 3.3 tendency of reliance in ADL scale was increased to 8.3 from 4.5, MMSE-K score was decreased to 15.9 from 21.7. There was no significant change in status of chronic illness. Postoperative delirium occurred in eight (47%) cases and all of them recovered completely. complications included bladder problem in eleven (66%) cases, temporary respiratory distress in two (12%) cases, hip dislocation in two (12%) cases, infection in one (6%) case. Overall thirteen (78%) cases were able to walk with supports.
CONCLUSION
This study indicates that physicians treation femur neck fractures in patients aged around ninety must anticipate worsening of the functional changes more especially in regard to walking level, activity of daily living and mental status, little changes of chronic disease status, complete recovery of postop delirium and high complication rate

Sang Won Park, Chang Yong Hur, Jong Ryoon Baek, Seong Jun Park
J Korean Soc Fract 2003;16(4):441-446.   Published online October 31, 2003
DOI: https://doi.org/10.12671/jksf.2003.16.4.441
AbstractAbstract PDF
PURPOSE
To analyze the factors predisposing to complications after internal fixation of femoral neck fracture.
MATERIALS AND METHODS
We reviewed retrospectively the results of percutaneous internal fixation of femoral neck fracture using multiple pinning, in 52 cases who were treated from Jan. 1996 to Dec. 2001. Relationship between the complications and several factors such as the age, sex, time interval from injury to operation, Garden stage, Singh index, internal fixation device and state of redction were analyzed.
RESULTS
The functional results by Lunceford criteria were excellent in 23 cases (44%), good in 15 cases (29%), fair in 2 cases (3.8%) and poor in 12 cases (23.1%). The avascular necrosis of the femoral head were occured in 14 cases (26.9%). Among these, 1 case of non-union, 2 cases of mal-union were accompanied. No stastically significant relationship between the age, sex, time interval from injury to operation, Garden stage, Singh index, internal fixation device, state of redction and complication. However, there was 4 times higher complication rate in Garden stage 3 or 4 group than its rate in Garden stage 1 (odds ratio 3.889), and 3 times higher complication rate in non-anatomical reduction group (odds ratio 3.22).
CONCLUSION
Factors predisposing to complications after internal fixation of femoral neck fracture seemed to closely relate with Garden stage and state of reduction.

The Significance of Posterior Cortex in Complicated Femoral Neck Fractures which were Internal Fixated
You Sung Suh, Seok Bong Jung, Soo Jae Yim, Jong Seok Park, Byung Ill Lee
J Korean Soc Fract 2002;15(4):511-518.   Published online October 31, 2002
DOI: https://doi.org/10.12671/jksf.2002.15.4.511
AbstractAbstract PDF
PURPOSE
When a surgeon carries out an operative treatment on a patient who has fractures of the femoral neck, he decides to do either the internal fixation for bony union or the aggressive treatment according to his experience and preparation, not according to the objective standard. The aim of this retrospective study is to prepare a guideline for the operative method.
MATERIALS AND METHODS
We analyse possible factors of the patient who has nonunion, avascular necrosis and loss of fixation after doing internal fixation in femoral neck fractures RESULTS: In this treated case of femoral neck, the appearance of complications are influenced by the maintenance of internal fixation, shape of fractures, osteoporosis, and the position of fixations; but in the complicated cases without the loss of fixation, the shape of fractures always have posterior cortical communition.
CONCLUSION
When we choose between simple fixation and aggressive treatments in cases of fractures of the femoral neck, we must treat according to the patient 's condition, displacement of the fracture, operative technique and existence of a posterior cortical comminuted fracture.

J Korean Soc Fract 2002;15(3):414-420.   Published online July 31, 2002
DOI: https://doi.org/10.12671/jksf.2002.15.3.414
AbstractAbstract PDF
PURPOSE
We report complications occurred from 6 patients among 14 patients who received the operation for their radial head and neck fractures by using the absorbable rod made by poly-glycolic acid(PGA).
MATERIALS AND METHODS
We analyze the postoperative results of 14 patients who recieved fixation by absorbable rod for the radial head and neck fractures from March 1991 to March 2000. All of the fractures were are reducible and modified Mason 's type II.
RESULTS
After average 15 months follow up, flexion contracture was average 20 degrees and full flexion was average 130 degrees. Complications were occurred in 6 cases. Osteolysis was occurred in 3 cases and in 2 cases among theses 3 cases, radial head excision was performed. Synovitis was occured in other 3 cases and in one case joint fluid was drainaged from operation wound for 2 weeks and in other 2 cases, synovitis was progressed to arthritis.
CONCLUSION
The absorbable rod made of PGA in radial head and neck fracture have relatively high rate of adverse tissue responses. So surgeon should consider adverse tissue response of PGA. Development of more biocompatible absorbable and slow degrading material should be needed.

Sung Jung Kim, Shin Yoon Kim, Gi Bong Cha, Chang Wug Oh, Il Hyung Park, Joo Chul Ihn
J Korean Soc Fract 2002;15(2):201-208.   Published online April 30, 2002
DOI: https://doi.org/10.12671/jksf.2002.15.2.201
AbstractAbstract PDF
PURPOSE
To investigate the relationship between the complications of intracapsular femoral neck fractures treated by multiple pinning and several affecting factors.
MATERIALS AND METHODS
Sixty-eight patients with intracapsular femoral neck fractures were treated by multiple pinning from March 1993 to January 2000 and followed at more than one year. Relationship between the complications such as failure of union, collapse of femoral head due to osteonecrosis of femoral head and several affecting factors including displacement of fracture according to Garden stage, state of reduction, position of screws, time interval from injury to operation, and fracture level were analyzed. The Fisher exact test, chi-square test, and multivariate logistic regression analysis were used to find the relevant factors influencing incidence of complications. Statistical significance was set at p < 0.05.
RESULTS
Position of screw was the most important single factor affecting the results of treatment of intracapsular femoral neck fracture (p=0.046). Moreover, the Garden stage and position of screw were revealed affecting the incidence of complications together with other factors (each p value was 0.028 and 0.027).
CONCLUSION
We considered that satisfactory position of screw was important to reduce complications after multiple pinning for intracapsular femoral neck fracture. And the results of operation also seemed to closely relate with multiple factors including Garden stage and status of reduction.

Kee Haeng Lee, Youn Soo Kim, Chang Hoon Jeong, Suk Ku Han, Hyoung Min Kim, Jun Seok Kim
J Korean Soc Fract 2001;14(4):567-574.   Published online October 31, 2001
DOI: https://doi.org/10.12671/jksf.2001.14.4.567
AbstractAbstract PDF
PURPOSE
To determine the value of bone scintigraphy in predicting avascular necrosis following femoral neck fracture, and to analyze of relationship between pintract sign (increased radioactivity along the pins) and avascular necrosis after multiple pinning of femoral neck fracture.
MATERIALS AND METHODS
We analyzed 20 femoral neck fractures, which were fixed with cannulated screws(14 cases) or Knowles pins(6 cases). The follow-up period was longer than 18 months, and bone scintigraphy was carried out at postoperative 3 weeks, 3 months interval to 1 year, 6 months interval to 2 years, and then every 1 year.
RESULTS
There were 14 cases with positive pin-tract sign and increased uptake of femoral head on bone scintigraphy performed at the postoperative 3 weeks, and I case with positive pin-tract sign and partially decreased uptake of femoral head. None of them developed avascular necrosis. There was I case with negative pin-tract sign and partially decreased uptake of femoral head, which showed increased uptake later and didn't develop avascular necrosis. There were 4 cases with negative pin-tract sign and generally decreased uptake of the femoral head, and all of them developed avascular necrosis.
CONCLUSION
Bone scintigraphy is a useful method predicting the avascular necrosis following femoral neck fracture, and pin-tract sign may be an early postoperative sign indicating that there is little possibility of development of avascular necrosis.

Sang Won Park, Seung Beom Han, Soon Hyuck Lee, Woong Kyo Chung, Seung Yong Wang
J Korean Soc Fract 2001;14(3):323-330.   Published online July 31, 2001
DOI: https://doi.org/10.12671/jksf.2001.14.3.323
AbstractAbstract PDF
PURPOSE
To evaluate the effectiveness of bone scintigraphy using 99mTc-methylene diphosphonate(99mTc-MDP) for prediction of viability of femoral head in femur neck fracture that have been treated with osteosynthesis.
MATERIALS AND METHOD
Thirty two patients were included in this study who underwent preoperative and postoperative bone scintigraphy using 99mTc-MDP following femur neck fracture. The uptake of istope was estimated visually as either normal or reduced compared with the opposite side. The complications as avascular necrosis and non-union were checked and compared with the preoperative and postoperative bone scintigraphy and the predictive values of positive and negative scintigraphy were calculated.
RESULTS
Among thirty-two patients, bone union occured in nineteen patients except 12 avascular necrosis and 1 non-union. Average bone union peried was 4.4 months and 50% was occured between 3 and 6 months. In seventeen patients who showed reduced isotope uptake, twelve patients developed complications and predictive value of positive scintigraphy was calculated as 0.76. In fifteen patients shown normal isotope uptake, none developed complications and predictive value of negative scintigraphy was calculated as 1.00.
CONCLUSION
Preoperative bone scintigraphy using 99mTc-MDP was useful method to evaluate the viability of femoral head following femur neck fracture and to choose the treatment modality of displaced femur neck fracture especially in elderly person.
