Published online October 31, 2020; DOI: https://doi.org/10.12671/jkfs.2020.33.4.210

Abstract PDF: Purpose
This study compared the clinical and radiographic results of two proximal femoral nail antirotation II (PFNA-II) angled by 125° and 130° in patients with intertrochanteric fractures.
Materials and Methods
From March in 2015 to September in 2016, 65 patients who underwent a closed reduction and internal fixation with PFNA-II for a femoral intertrochanteric fracture were evaluated retrospectively. The minimum follow-up period was two years. Of those, 30 and 35 patients underwent 125° angled PFNA-II and 130° angled PFNA-II, respectively. The clinical performance was evaluated using the Harris hip score, WOMAC (Western Ontario and McMaster Universities Osteoarthrtis Index), and UCLA (University of California Los Angeles) score. Radiographic analyses were performed using standardized anteroposterior and lateral radiographs to assess the implant position and quality of reduction. The blade length, distance between the blade tip and the tip of the greater trochanter, and distance between the blade tip and the most lateral protrusion point of the greater trochanter in the two groups were measured and compared.
Results
The clinical results, including the Harris hip score, WOMAC, and UCLA, were similar in the two groups at the last follow-up postoperatively. In the radiography evaluation, the implant position, quality of reduction, and the blade length were similar in the two groups. The distances between the blade tip and the tip of the greater trochanter were 52.60±3.53 mm and 58.07±5.54 mm in the 125° angled PFNA-II and 130° angled PFNA-II groups, respectively. The distance between the blade tip and the most lateral protrusion point of greater trochanter were 16.48±2.54 mm and 21.19±4.43 mm in the 125° angled PFNA-II and 130° angled PFNA-II groups, respectively. The differences were significant (p=0.031, p=0.012).
Conclusion
The operation with the 125° angled PFNA-II showed a more superior and lateral position of the blade than that with the 130° angled PFNA-II. Nevertheless, lateral thigh pain can occur when the blade is positioned superolaterally.

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

Abstract

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.

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

Abstract 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.

Abstract PDF: PURPOSE
In the femoral head fracture associated with posterior dislocation of hip, we analyzed the clinical results according to the fracture types and treatment methods to promoting the guide of treatment.
MATERIALS AND METHODS
We used 20 cases of fractured femoral head with posterior dislocation of hip from January 1990 to December 1997, and analyzed the treatment methods and clinical results according to the Pipkin classification.
RESULTS
Among the 20 cases, male was 19 cases(95%), motor vehicle accident contributed 15 cases(75%), and the case of type II and IV of Pipkin classification were 7(35%) and 9(45%) cases. Closed reduction performed within 12 hours after injury with good results was conducted in 9 cases(60%) among the 15 cases. According to the treatment methods after closed reduction, good result was showed only 3 of 8 cases(37.5%) in the conservative treatment, whereas 8 of 12 cases(66.7%) in the operative treatment. According to the type of Pipkin classification, good result was showed 3 of 6 cases(50%) in conservative treatment and all of 3 cases in operative treatment among the 9 cases of type I and II, whereas none of 2 cases in conservative treatment and 5 of 9 cases(56%) in operative treatment among the 11 cases of type III and IV. The following complications were encounted; 2 cases of avascular necrosis, 1 case of traumatic arthritis, 1 case of peroneal nerve palsy and 1 case of nonunion CONCLUSION: Good results were obtained in patients with early, stable, and accurate reduction. The Computed Tomogram was helpful to find the small fragment and check the accurate reduction. Open method that restoration joint congruity seemed to be the better procedure than closed method.

Published online April 30, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.2.222

Abstract PDF

PURPOSE
: The purpose of this paper was to present the clinical and roentgenographic results were obtained with bipolar hemiarthroplasty as a primary treatment for comminuted unstable intertrochanteric fracture in elderly patients with severe osteoporosis. The goal of this treatment is early ambulation with early weight bearing to prevent the complications such as a deep vein thrombosis, pulmonary embolism, pneumonia or atelectasis, and pressure sore.
MATERIALS AND METHODS
: Twenty consecutive patients who were more than seventy years old with severe osteopotosis and had an comminuted unstable intertrochanteric fractures were treated by primary bipolar hemiarthtoplasty from January 1995 through January 1998 at the Department of Orthopaedic Surgery of Soonchunhyang University Hospital. If there were fractured at the lesser or the greater, a circlage wire or Dall-Miles system (trochanter cable grip system) was passed through the lesser and the greater trochnater to permit its subsequent fixation to the medial and the lateral side of the femoral component. The functional results were judged according to the hip rating scale of Merle d' Aubigne.
RESULTS
: The mean age at operation was 79.8(70 to 92) years old. The most common type according to the Evans classification system was I -d(10 cases, 50%). Singh index was case(5%) of Grade I , 7 cases(35%) of Grade II, 10 cases(50%) of Grade III and 2 cases(10%) of Grade IV. The mean bone mineral density(BMD) was -4.24(-6.95 - -3.17). The functional results in 75% of the patients were rated as excellent, very good, or good and in 25% as fair, poor, or bad.
CONCLUSION
: Primary bipolar hemiarthroplasty for the treatment of comminuted unstable intertrochanteric fractures in elderly patients with severe osteoporosis could return these patients to their pre-injury level of activity quickly, thus obviating the postoperative complications caused by immobilization.

A Clinical Analysis of Distal Fracture of the Femur with DCS Fixation & Early Exercise: Soo Jae Yim, Dong Jin Kim, Seung Ryul Yoon; J Korean Soc Fract 1998;11(3):514-521. Published online July 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.3.514

Abstract PDF

Fracture of the distal femur is not as common as femoral shaft or hip fracture. A widening medullary canal, thin cortex, osteopenia make open reduction and internal fixation difficult, enen for an experienced surgeon, The surgical treatment for supracondylar femoral fractures has a better outcome becuse of improved implants, fixation technique and preoperative planing during the past two decades. We reviewed 33 cases of fractures of the distal femur at Soon Chun Hyang Gumi Hospital from June, 1992 to March, 1996 with minimum 12 months follow up. Following results were obtained. 1. In age distribution, fourth decade was most frequent. 2. The most common cause of these fractures was traffic accident. 3. The most common fracture type was type C by Muller classification. 4. Complication were as follows : pain, knee joint stiffness, bursitis, skin infection etc 5. The satisfactory results could be obtained by the open reduction and rigid internal fixation followed by early R.O.M. exercise of knee joint.

Abstract PDF: Fracture of the talus are relatively uncommon injury, when they occur, however, they are of major importance, because of the relativily heigh frequency of complications and long term disability. Complications such as non-union, avascular necmsis, traumatic arthritis are frequently developed as a late sequele in fracture or fracture-dislocation of the talus because of talar surface is covered mainly with articular ratilage and poor blood supply. Authors have reviewed 19 cases of the talus fracture & fracture-dislocation surgically treated at Soonchunhyang University Kumi Hospital from January 1987 to October 1995 with minimal 1 year follow up period. The result were as follows 1. Of 19 cases, 16 male and 3 female with their average age of 29.8 years. 2. The rause of injury were traffic accident(motor veiheicle accident)-lO/l9 cases (53%), direct trauma-2/l9 cases(11%), sport injury-l/l9 cases(5%) and fall from height-6/l9 cases(32%). 3. The most common concomittant injury was the ipsilateral fracture of the tibiofibular (including medial malleolar fracture)-9/19 cases(47%). 4. According to the hawkinsclassification, 5 cases in type I, 8 cases in type II, 5 cases in type III and 3 cases in type IV. 5. According to the Hawkinstherapeutic criteria, excellent results in 8 cases, good in 1 cases, fair in 3 cases but poor in 1 case. 6. Avascular necrosis was occured in 7 cases(37%) and ankle stiffness in 4 cases(21%) but nonunion was not observed.

Abstract PDF: Posterior hip dislocation with femoral head and neck fracture(Pipkin type III) was considered as a rare injury, However, the advance of high speed motor vehicle accidental injury has contributed to its increased incidence and the choice of treatment is still controversial. Mechanism of injury was considered as a kind of secondary trauma of inversion or internal rotation force with hip joint was flexed position state. Three cases of posterior hip dislocation with femoral head and neck fracture(Pipkin type III)have been experienced and follow up still now at Soon Chun Hyang University hospital. The results were evaluated by Thomson Epsteins clinicoradiologic criteria and Harris hip score and follow up radiologic findings. As a results of this study, we are more prefer primary open reduction and rigid internal fixation than primary joint replacement arthroplasty due to be occured in young age group. And futher evaluation should be needed.

Clinical Comparison in Intramedullary Fixation to Plate Fixation on Treatment of the Both Forearm Bone Fractures: Seog Yeong Jeong, Ung Moon, Soo Jae Yim, Seung Ryeol Yoon, Soo Kyun Rah, Chang Uk Choi; J Korean Soc Fract 1995;8(4):893-901. Published online October 31, 1995; DOI: https://doi.org/10.12671/jksf.1995.8.4.893

Abstract PDF

The diaphyseal fractures of radius and ulnar have many problems like nonunion, malunion and functional disturbance with conservative treatment. Therefore, open anatomical reduction and rigid internal fixation have been widely used. The plate fixation has been employed in most both forearm bone fractures and the intramedullary pinning usually used in cases of the open fractures, comminuted types, multiple fractures or poor general conditions. Seventeen patients were treated with semitubular plate and eighteen cases by the closed or open reduction and intramedullary fixation with Rush pin(the operation methods were decised alternatively) were followed up more than one year at Soonchunhyang Gumi Hospital from June 1988 to Nov. 1992 and the results were compared and analyzed clinically. 1. Those two groups were demographically similar. 2. The operation time was 65 minites in Rush pin group, 85.6 minutes in plate group and the blood loss was 37.1cc in Rush pin group,85.3cc in plate group. 3. The immobilization period and the radiologic bone union time did not differentiate two groups significantly. 4. In plated group, one nonunion and one radius refracture after union(plate removed state) were occurred. 5. Between the two operatio methods selected alternatively, immobilization period, radiologic bone union and functional results were not different significantly, but the Rush pinning method was preferred due to simple operation technique, small operation scars, short operation time, a little blood ioss, a few complications.
