Distal tibial metaphyseal fractures are commonly caused by high-energy injuries in young men and osteoporosis in older women. These fractures should be clearly distinguished from high-energy pilon fractures. Although the optimal surgical intervention methods for distal tibial metaphyseal fractures remain uncertain and challenging, surgical treatments for nonarticular distal tibia fractures can be broadly divided into two types: plate fixation and intramedullary nail (IMN) fixation. Once functional reduction is achieved using an appropriate technique, distal tibial nailing might be slightly superior to plate fixation in reducing postoperative complications. Thus, the surgical strategy should focus on functional realignment and proceed in the following sequence: (1) restoring the original tibial length, regardless of whether fibular fixation is to be done; (2) making the optimal entry point through an anteroposterior (AP) projection based on the overlapping point between the fibular tip and lateral plateau margin; (3) placing Kirschner wires (Ø2.4 mm) as blocking pins (in the AP orientation for coronal control and in the mediolateral [ML] orientation for sagittal control) as close to the upper locking hole as possible without causing further comminution on the concave aspect of the short fragment; and (4) making the the distal fixation construct with at least two ML and one AP interlocking screw or two ML interlocking screws and blocking screws. After the IMN is adequately locked, blocking pins (Ø2.4 mm) need to be replaced by a 3.5 mm screw.
Purpose The purpose of this study is to analyze the clinical results of patients with basicervical fracture undergoing cephalomedullary nailing (CMN) with an additional cannulated screw fixation compared to only performing CMN. We hypothesized that a difference may exist in the clinical outcomes if an ad-ditional screw is fixed with CMN compared to only performing CMN in basicervical fracture. Materials and Methods A total of 28 consecutive patients who underwent CMN for basicervical fracture were included. In 9 cases, only CMN was conducted, and in 19 cases, an additional cannulated screw fixation was performed with CMN. Bone union, sliding distance, reduction status, and fixation failure were evaluated by postoperative radiography, and ambulatory ability was evaluated by functional results. These findings were compared between a group of CMN and a group of CMN with an additional cannulated screw. Results There were 4 males and 24 females with a mean age of 84 years (range, 69–100 years). No significant difference was found in postoperative reduction, tip-apex distance, bone union, and walking function recovery after surgery between the two groups, but in the sliding distance of the lag screw, the CMN group demonstrated more sliding (6.2 mm [range, 2.5–13.4 mm] vs 3.5 mm [range, 0.1– 9.2 mm]; p=0.045). Among the two groups, only one case of fixation failure at the postoperative four months was observed in the CMN group (p=0.321), and hemiarthroplasty with nail construct removal was performed. Conclusion CMN with additional cannulated screw fixation is a safe and reliable surgical option in basicervical fracture. It provided favorable clinical outcomes and may be a good alternative for treating basicervical fracture.
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.
According to the Letournel classification, a transverse fracture is the only elementary fracture pattern that breaks both the anterior and posterior border of the innominate bone. A transverse acetabular fracture separates the innominate bone into two segments: the iliac segment and the ischiopubic segment. Therefore, minimally displaced transverse fractures can be stabilized by purchasing both segments with a large-diameter single screw. Although it is not a stable internal fixation construct compared with plates and screws, it provides sufficient stability to promote early mobilization and early weight-bearing while minimizing the risk of secondary displacement and preventing secondary complications associated with prolonged bed rest and immobilization. The authors successfully treated a case of minimally displaced transverse acetabular fracture with percutaneous column fixation using a retrograde fashion of a single anterior column screw. This report discusses the case with a literature review and deliberates the usefulness of the procedure.
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.
Purpose To evaluate the usefulness of percutaneous cannulated screws with tension band wiring (PC-STBW), a minimally invasive surgical technique, compared to conservative treatment for a minimally displaced patella transverse fracture. Materials and Methods The subjects included patients from 2010 to 2019 with transverse patella fractures, who were diagnosed as minimally displaced fractures, and were followed up for at least 1 year. Of these, 61 patients who were treated with cylinder casts were classified as Group A, and 53 patients who were treated with PCSTBW were classified as Group B. The clinical evaluation was carried out by evaluation of the radiographic bone union and calculation of the Bostman knee score. Any complications observed were investigated. Results All patients in both groups showed no further displacement of the fracture gap, and the bone union was achieved in all cases. The functional evaluation of the knee joint measured at the 8- and 12-week follow-up showed superior results in Group B wherein subjects were treated with surgery, and similar results were seen in both groups during the 6 months and 1-year follow-up. One case in Group A suffered the complication of knee stiffness. Conclusion For the treatment of minimally displaced transverse patellar fractures, both conservative treatment and PCSTBW showed similar good results at the 6-month and one-year follow-up. However, the PCSTBW technique showed superior clinical results in the early stage follow-up within 12 weeks.
Purpose This study compared the radiologic and clinical outcomes of metacarpal fractures treated with two minimally invasive surgical techniques: Kirschner wire (K-wire) fixation and headless screw fixation. Materials and Methods This study included 52 patients (46 males and 6 females; age 18-55 years) with distal metacarpal fractures (middle and distal shaft, including the neck) who had undergone K-wire fixation or headless screw fixation. All subjects were followed up for at least six months. The radiologic assessments were performed to evaluate the angular deformity and shortenings. The total active motion (TAM), grip strength, and patients’ subjective functional assessment were measured to evaluate the hand function. The time taken to return to work (RTW) and adverse events were analyzed. Results Of the 52 cases, metacarpal fractures treated with headless screw fixation and K-wire fixation showed a significant difference associated with early RTW (p<0.05). There were no significant differences between the subjects treated with K-wire fixation and those with headless screw fixation in terms of the radiologic measurement, hand function examinations, complications, and adverse events (p>0.05). Conclusion After a six-month follow-up, minimally invasive K-wire fixation and headless screw fixation produced similar clinical and radiologic outcomes in subjects with metacarpal fractures. Compared to K-wire fixation, however, headless screw fixation led to earlier functional recovery and might be a better option for treating metacarpal fractures in this regard.
Purpose This study examined the effect of lag screw insertion on proximal fragments by separating the right and left sides of intertrochanteric fractures in elderly patients that underwent intramedullary nailing. Materials and Methods Patients aged ≥65 years that underwent intramedullary nailing after a diag-nosis of intertrochanteric fractures during the period February 2012 to May 2016 were included in the study. The subjects were divided into right and left side groups. The effect of the clockwise rotational force generated when a lag screw was inserted on the proximal fragment was evaluated in both groups. Results In the right and left groups, most proximal fragments were located in the intramedullary canal after surgery (45 cases [75.0%] and 67 cases [73.6%], respectively). Clockwise rotation due to lag screw placement in the right group occurred in two cases (3.3%), which both showed internal rotation, and in four cases (4.4%) in the left group, all of which showed external rotation. Conclusion After intramedullary nailing of intertrochanteric fractures in elderly patients, proximal fragments were mostly located in the intramedullary cavity. The results obtained confirmed that the clockwise rotational force generated by lag screw insertion did not affect left or right sides.

Purpose This study was undertaken to compare outcomes of screw fixation and non-fixation of a small-sized posterior malleolar fragment involving less than 25% articular surface in ankle trimalleolar fractures.
Materials and Methods: A total of 32 consecutive ankles (32 patients), with posterior malleolar fragment involving 15%-25% of the joint surface, were enrolled in the study. Patients were divided into 2 groups according to whether the fragment was fixed or not (fixed: 20 ankles, non-fixed: 12 ankles).
The minimum follow-up period was 12 months. Median size of the posterior malleolar fragment in the fixed and non-fixed groups were 24.6% (range, 22.3%-25.0%) and 22.1% (range, 17.4%-24.3%), respectively. Complications as well as clinical and radiographic outcomes were compared and analyzed between the two groups.
Results: Clinical outcomes, including American Orthopaedic Foot & Ankle Society (p=0.501), visual analogue scale (p=0.578), and ankle range of motion (p=0.552), showed no difference between groups at the final follow-up. No differences were obtained in the radiographic outcomes, including joint stepoff (p=0.289) and fragment gap (p=0.289). Complications, including 1 case of delayed union and 1 case of wound infection, were reported in the fixed group.
Conclusion: Clinical outcomes and radiographic outcomes of the non-fixation group were satisfactory and comparable to the fixation group. Our results indicate that anatomical reduction with small-sized posterior malleolar fragment in ankle trimalleolar fractures is sufficient for satisfactory outcomes, without the need for additional internal fixation.
PURPOSE This study compared the clinical and radiological results between two groups of patients with percutaneous fixation or conventional fixation after hardware removal. MATERIALS AND METHODS The study analyzed 68 patients (43 open fixation and 43 percutaneous screw fixation [PSF] 25) who had undergone fixation for unstable thoracolumbar fractures. The radiologic results were obtained using the lateral radiographs taken before and after the fixation and at the time of hardware removal. The clinical results included the time of operation, blood loss, time to ambulation, duration of the hospital stay and the visual analogue scale. RESULTS The percutaneous pedicle screw fixation (PPSF) group showed better results than did the conventional posterior fixation (CPF) group (p<0.05) in regard to the perioperative data such as operation time, blood loss, and duration of the hospital stay. There were no significant differences in wedge angle, local kyphotic angle, and the ΔKyphotic angle on the postoperative plane radiographs between the two groups (p>0.05). There were no significant differences in the wedge angle and local kyphotic angle after implant removal (p>0.05) between the two groups as well. However, there were significant differences in the segmental montion angle (p<0.001), and the PPSF group showed a larger segmental motion angle than did the CPF group (CPF 1.7°±1.2° vs PPSF 5.9°±3.2°, respectively). CONCLUSION For the treatment of unstable thoracolumbar fractures, the PPSF technique could achieve better clinical results and an improved segmental motion angle after implant removal within a year than that of the conventional fixation method.

The subtrochanteric area is the place where mechanical stress is most concentrated in the femur. When a fracture happens, bone union is delayed and nonunion often occurs. The recommended treatment for atypical fractures is an anatomical reduction of the fracture site as the frequency of nonunion is higher than that of ordinary fractures. Various reduction methods have been suggested, and good results have been obtained. On the other hand, the occurrence of posterior displacement of the distal fragment during the insertion of an intramedullary nail is often overlooked. This is probably because the bone marrow of the femur tends to form an elliptical shape in the anteroposterior direction. The author attempted to insert a blocking screw into the distal part of the fracture to prevent posterior displacement of the distal fragment while performing intramedullary nailing of the femur fracture and achieved a good reduction state easily.
Avulsion fracture of the posterior cruciate ligament from its femoral insertion is quite rare, particularly in adults, and the treatment guidelines have not been established. A 68-year-old female patient with residual poliomyelitis presented with an avulsion fracture of the femoral insertion of the posterior cruciate ligament after a falling accident and was treated with arthroscopic headless compression screw fixation and pull-out suture of the avulsed ligament. We report this case with a relevant discussion of this type of injury.
A 22-year-old female patient visited the emergency room (ER) after a pedestrian traffic accident in a drunken state. An examination at the ER revealed fractures at the right side of the sacral ala, sacral foramina, left anterior acetabulum, right inferior ramus, and right superior articular process of S1. She underwent spino-pelvic fixation and iliosacral (IS) screw fixation. One year later, bone union was completed and implant removal was performed and the treatment was completed without complications. The authors recommend spino-pelvic fixation and IS screw fixation for unstable sacral fractures as one of the excellent methods for obtaining posterior stability of the pelvis among the various treatments of unstable sacral fractures.
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.

PURPOSE Iliosacral screw fixation is an effective and less invasive method that is used widely for the definitive treatment of unstable pelvic ring injuries. On the other hand, fixation failures after iliosacral screw fixation have been reported in vertically unstable pelvic ring injuries. This study examined the surgical outcomes of posterior pelvic fixation using S1 and S2 screws in vertically unstable pelvic ring injuries. MATERIALS AND METHODS Between January 2011 and April 2016, 17 patients with vertically unstable pelvic ring injuries who met the minimum 1 year follow-up criteria were treated with internal fixation using posterior pelvic S1 and S2 screws. Their mean age was 43.9 years. According to the AO/OTA classification, 10 patients had C1, 6 had C2, and 1 had C3 injuries. Surgical treatments of single or multiple steps, where necessary, were performed by two surgeons. The clinical and radiologic outcomes were assessed retrospectively using radiographs and medical records. RESULTS Overall, 16 patients had bone healing without screw loosening; however, one patient could not maintain anterior pelvic fixation because of an open fracture and deep infection in the anterior pelvic ring. Of five patients who complained of neurological symptoms after injury, three had partially recovered from their neurological deficit. At the last follow-up, the clinical outcomes according to the Majeed score were excellent in 5, good in 6, fair in 4, and poor in 2 patients. The postoperative radiologic outcomes by Matta and Tornetta's method were excellent in 5, good in 8, and fair in 4 patients. Malposition of the S2 screw was identified in one case. The mean time to union was 14.6 weeks after surgery. CONCLUSION S1 and S2 screw fixation can be an effective treatment option for posterior pelvic stabilization in vertically unstable pelvic ring injuries when considering the surgical outcomes, such as screw loosening and loss of reduction.

Hip fractures are common among elderly individuals. Internal fixation with the intramedullary system has been widely used to treat intertrochanteric femur fractures. The Gamma 3 nail is a useful device for fixating trochanteric fractures of the proximal femur. We report a rare complication of medial pelvic penetration of the lag screw of a Gamma 3 nail two months after surgery. There was a complete separation between the nail body and lag screw, and the lag screw penetrated through the acetabulum into the pelvis. We report a case of unstable intertrochanteric fracture with intrapelvic penetration after surgical treatment with proximal femoral nailing and a case followed by fatal results.

Most radial head fractures occur as the result of low-energy mechanisms, such as a trip or fall on the outstretched hand. These fractures typically occur when an axial load is applied to the forearm, causing the radial head to hit the capitellum of the humerus. Good results are shown with nonsurgical treatments for Mason type 2 fractures. However, if there is a limitation of elbow joint exercise or displacement of more than 2 mm, an operative treatment should be considered. We treated two patients with arthroscopic assisted bioabsorbable screw (K-METâ„¢; U&I Corporation, Uijeongbu, Korea) fixation for radial head fractures to prevent complications of open reduction and minimize radiation exposure.

In children with open physis, avulsion fracture of the tibia eminence, as an anterior cruciate ligament (ACL) injury, is more commonly observed than an ACL rupture. Pure cartilaginous avulsions of the ACL tibia insertion seldom occurs. In such case, cartilaginous lesion is frequently overlooked or misdiagnosed on plain radiograph and may result in a less favorable treatment outcome. We report two cases of cartilaginous tibia eminence fractures of the children that were initially overlooked from plain radiographs, and then diagnosed by magnetic resonance imaging, which was ultimately treated by arthroscopyassisted headless compression screw fixation.
PURPOSE The purpose of this study was to introduce our method of stabilizing unstable intertrochanteric fractures by using the dynamic hip screw (DHS) with a beta-tricalcium phosphate (β-TCP) graft and to compare the outcomes of this procedure with those of the conventional DHS without β-TCP. MATERIALS AND METHODS Patients who underwent surgery by using DHS between March 2002 and January 2016 were retrospectively reviewed for analysis of the outcomes. The inclusion criteria were: 1) age of 60 years and older; 2) low-energy fracture resulting from a fall from no greater than the standing height; 3) multifragmentary pertrochanteric fracture (AO classification 31-A2.2, 2.3); and 4) follow-up of over 3 months. We compared 29 patients (29 hips) who underwent surgery, using DHS without β-TCP, with 29 age-sex matched patients (29 hips) who underwent surgery using DHS with grafted β-TCP granules to empty the trochanter area after reaming. We investigated the fracture union rate, union time, and length of lag screw sliding. RESULTS Bone union was achieved in all cases. The mean union time was 7.0 weeks in the β-TCP group and 8 .8 weeks in the non-β-TCP group. The length of lag screw sliding was 3.6 mm in the β-TCP group and 5 .5 mm in the non-β-TCP group. There were no implant failure cases in both groups. CONCLUSION The β-TCP graft for reinforcement DHS acquired satisfactory clinical outcomes for treating unstable intertrochanteric fractures.
PURPOSE The purpose of this study is to evaluate the postoperative outcomes of elderly patients with stable 2-part intertrochanteric femur fractures surgically treated using dynamic hip screw with 2-hole side plate. MATERIALS AND METHODS From February 2008 to January 2014, 50 patients older than the age of 65 years, who had been followed-up for more than 6 months after the operation at The Catholic University of Korea, Bucheon St. Mary's Hospital were enrolled. A clinical evaluation of the skin incision length, operating time, and ambulatory status, using Clawson's Ambulation Capacity Classification, was performed, and a radiologic evaluation of Fogagnolo reduction quality, tip-apex distance (TAD), Cleveland index, sliding extent of lag screws, time duration till bony union, and complications was also done. RESULTS The mean skin incision length was 9.8 cm (range, 8-13 cm), the mean operating time was 41.4 minutes (range, 30-60 minutes), and 32 patients recovered their ambulatory function. Forty-eight patients gained bony union, and the time lapsed till union was average 10.6 weeks (range, 8-16 weeks). The evaluation of postoperative radiologic images showed the following reduction statuses by the Fogagnolo classification: 46 cases of "Good", 3 cases of "Acceptable," and 1 case of "Poor." Moreover, the mean TAD was 18.9 mm (range, 9.0-24.9 mm). While 45 cases fit into the zone 5 of the Cleveland index, other 3 were within zone 8 and the other 2 were within zone 6. The mean sliding length of the lag screws were 4.9 mm (range, 0.1-19.4 mm). There were a case of nonunion and a case of periprosthetic infection with nonunion as complications. CONCLUSION Using dynamic hip screws with 2-hole side plate for stable 2-part intertrochanteric femur fractures in elderly patients showed satisfactory results with respect to the recovery of ambulatory functions and bony union.
PURPOSE The purpose of this study was to evaluate the radiologic and clinical outcomes after intramedullary nailing with Poller screw insertion at initial stage in infraisthmal femur shaft fractures. MATERIALS AND METHODS Seven consecutive patients (7 femurs) treated with antegrade intramedullary nailing with Poller screw insertion for the infraisthmal femur shaft fracture were reviewed retrospectively. There were 4 male and 3 female patients. Mean age was 46.1 years (20-72 years). Operative time including Poller screw insertion, time for union, malalignment, and range of motion were evaluated. RESULTS All 7 cases had primarily healed successfully. Mean time for radiologic union was 19.1 weeks (16-24 weeks) postoperatively. One case had 5 degree valgus malalignment. One case of 15 mm shortening was reported and he required shoe lift orthosis. All cases had a full range of motion in hip and knee joint. CONCLUSION Antegrade intramedullary nailing with Poller screw insertion is useful in the initial treatment of infraisthmal femur shaft fracture, because it could provide additional stability. An additional 20 minutes were required but a Poller screw should be considered according to the anatomic location of a femur shaft fracture.
PURPOSE The aim of this study was to analyze the use of a compression hip screw with a trochanter stabilizing plate for treatment of reverse oblique intertrochanteric fractures. MATERIALS AND METHODS We reviewed the results of 33 cases of reverse oblique intertrochanteric fracture treated with a compression hip screw with a trochanter stabilizing plate from January 2000 to December 2012 which were followed-up for more than one year. We evaluated postoperative bone union period, change of neck-shaft angle, sliding of hip screw, and other complications. RESULTS Of 33 patients, satisfactory reduction was achieved in 28 patients. Five patients had an unsatisfactory reduction, with two cases of excessive screw sliding, one of broken metal, one of varus deformity, and one of internal rotation deformity. We performed corrective osteotomy in varus and internal rotation deformity and partial hip replacement in a case of excessive screw sliding. Bone union was achieved in 29 patients, and the average bone union period was 19.2 weeks. CONCLUSION We consider that a compression hip screw with a trochanteric stabilized plate is a good option for treatment of reverse oblique intertrochanteric femoral fractures. However, adequate fracture reduction and ideal implant placement are a basic necessity for successful treatment.
As volar plate fixation of distal radius fracture becomes more common, reports of ruptured extensor pollicis longus tendon by a protruding distal screw tip are also increasing steadily. Authors have experienced a rare case of ruptured extensor pollicis longus tendon at the prominent proximal screw of fixed volar plate for distal radius fracture, and we report it herein with a review of the literature.
PURPOSE To evaluate the outcomes of surgical treatment modality in unstable sacral fractures combined with spinal and pelvic ring injury depending on the presence of spino-pelvic dissociations. MATERIALS AND METHODS The subjects were 16 patients, with unstable sacral fractures combined with spinal and pelvic ring injuries, were operated from July 2004 to January 2011. The patients were divided into 2 groups depending on the presence of spino-pelvic dissociations: those with dissociations were group 1, and those without dissociations were group 2. Group 1 was treated with spino-pelvic fixations using iliac screw, while group 2 was treated with percutaneous iliosacral screw fixations. The availability of the radiological bony union with its application periods, and clinical results using visual analogue scale (VAS) and oswestry disability index (ODI) were evaluated, retrospectively. RESULTS Out of 16 patients, 8 patients in group 1 were treated with spino-pelvic fixation using iliac screw, and 8 patients in group 2 were treated with percutaneous iliosacral screw fixation. The mean bony union period was 17.4 weeks in group 1, and 19.6 weeks in group 2. The Mean VAS and ODI scores on the last follow-up were 2.5 points and 15.6 points in group 1, 2 points and 18.8 points in group 2, respectively. Both groups had favorable clinical results at the last follow-up. CONCLUSION For surgical treatments of unstable sacral fractures, spino-pelvic fixation using iliac screws is advised for cases with combined spino-pelvic dissociation, while percutaneous iliosacral screw fixation is advised for cases without combined dissociation.

Metallosis has been reported in the setting of weight-bearing joint arthroplasties, like the hip and knee joints. However, the prevalence of metallosis in non-articular portions is very uncommon. We report a rare case of a patient who had metallosis secondary by fibular nonunion after fixation with plate and screw. In addition, we discuss the clinical and the operative findings, as well as the outcome of this uncommon complication.

PURPOSE To compare the result between the compression hip screw (CHS) and intramedullary (IM) nail for the treatment of AO/OTA A2.2 intertrochanteric fracture. MATERIALS AND METHODS We retrospectively reviewed 95 cases of AO/OTA A2.2 intertrochanteric fracture, which were treated with CHS or IM nail by one surgeon from March 1994 to December 2009. One group was treated with CHS (Group I, 28 cases) and the other was treated with IM nail (Group II, 67 cases). We evaluated the mean operation time, the amount of bleeding and transfusion, hospital duration, radiological results and the clinical outcome with the mobility score of Parker and Palmer. RESULTS Radiologically, the tip-apex distance, change of neck-shaft angle, and union time were not significantly different between both groups (p>0.05). Clinically, the mean operation time, the amount of bleeding and transfusion, hospital duration and the mobility score were not significantly different (p>0.05). The post-operative complications were lag screw slippage over 25 mm (1 case) and loosening of device (1 case) in group I. In group II, there were perforation of the femoral head (1 case), nail breakage (1 case) and deep infection (1 case). CONCLUSION There was no significant differences that are clinical and radiological results in the treatment of AO/OTA A2.2 intertrochanteric fracture, using CHS and IM nail.

PURPOSE To acquire anatomical data for the normal pelvic bone structure using three-dimensional computed tomography (3D CT) and to propose the most appropriate angle and screw length for safe screw insertion during symphysis pubis plating. MATERIALS AND METHODS We performed 3D CT analysis in 52 patients who required plating and selected a medial and lateral insertion point between the symphysis pubis and the pubic tubercle. Using a three-dimensional medical image analysis program, we evaluated the appropriate screw length, sagittal angle, and oblique angle at each point in this cohort. RESULTS At the medial point, the sagittal angle was determined to be 49.1degrees with an average screw length of 49.4 mm. At the lateral point, we calculated an average screw length of 49.1 mm, oblique angle of 23.2degrees, and sagittal angle of 45.7degrees. The screw length was longer in men than in women (4.6 mm and 7.3 mm, respectively) at the medial and lateral point. CONCLUSION At the symphysis pubis diastasis, we can insert the screw caudally at 49degrees with a minimal length of 37 mm at the medial point. We can insert the screw caudally at 46degrees, medially at 23degrees, with a minimal 34 mm length at the lateral point.
PURPOSE To report the treatment results of anatomical reduction of all fracture fragments and internal fixation using an inter-fragmentary screw and plate in displaced mid-shaft clavicle fracture with comminution. MATERIALS AND METHODS Between June 2005 and August 2011, 13 consecutive displaced clavicle fractures with comminution (Edinburgh classification IIB2) treated by anatomic reduction and internal fixation using inter-fragmentary screw and plate were retrospectively evaluated. There were 11 male and 2 female patients with a mean age of 37.4 years (15~55 years). The right clavicle was injured in 4 patients and the dominant arm was involved in 46%. The mean duration from trauma to surgery was 7.0 days. The cause of injury was a traffic accident in three, a fall in two, and sports activity or direct injury in eight patients. All of the fracture pieces were anatomically reduced and fixed with inter-fragmentary screws. An additional plate was applied to maintain and reinforce the reduction of the fracture. Radiographic assessments for the numbers of fragments and the amount of shortening and displacement were performed. To verify the fracture healing and determine the time from fracture surgery to union and complications, all of the radiographs taken after surgery were evaluated. RESULTS The number of fragments was 2 in 7 cases, 3 in 5 cases, and 6 in one case. The mean shortening of the clavicle was 1.1 cm (0.3~2.1 cm) and mean displacement between the main fragments was 2.6 cm (1.3~4.5 cm). The mean duration of follow-up was 16.5 months (8~26 months). Radiographic union was achieved in all patients with a mean time to union of 10.8 weeks (8~14 weeks). There were no complications including metal failure, nonunion, or infection. CONCLUSION Anatomical reduction of all the fracture fragments and fixation using inter-fragmentary screws in addition to the usual plate fixation showed good fracture healing in displaced clavicle fracture with comminution.

PURPOSE To analyze the clinical and radiological results of the different fixation methods according to the type and displacement of unstable pelvic ring injuries. MATERIALS AND METHODS Twenty-three patients with unstable pelvic ring injuries from January 2005 to December 2009 were classified according to the AO/OTA classification system. When patients had been diagnosed with unstable pelvic ring injuries with partial instability, they were treated by anterior fixation with a plate and posterior percutaneous iliosacral screw fixation. When patients had been diagnosed with unstable pelvic ring injuries with complete instability, they were treated by open reduction and anterior to posterior fixation with a plate through the ilioinguinal approach. The radiological results were evaluated using Matta and Saucedo's method, and the clinical results were evaluated using Rommens and Hessmann's method. RESULTS The outcomes from the radiological evaluation were that the displacement of the posterior pelvic ring were improved by about 6.65 mm in unstable pelvic ring injuries with partial instability. The displacement of the posterior pelvic ring were improved by about 7.8 mm in unstable pelvic ring injuries with complete instability. The clinical results were excellent in 13 cases and good in 6 cases on latest follow-up. CONCLUSION Good results can be achieved by selecting the treatment method according to the type of unstable pelvic ring injurie and displacement.

PURPOSE To evaluate the radiologic results between compressive hip screw and compressive hip screw with additional trochanteric stabilizing plate in patients with femoral unstable intertrochanteric fractures in patients with more 65 years old. MATERIALS AND METHODS From 2006 to May 2009, 121 cases were included. Group I (compressive hip screw only) was 54 cases and group II (compressive hip screw with trochanteric stabilizing plate) was 67 cases. We checked the lag screw sliding, lateral translation of greater trochanter, changes of neck-shaft angle and complications through periodic follow up of radiographs. RESULTS Mean lag screw sliding was 7.6 mm in group I and 3.9 mm in group II (p=0.001). Mean lateral translation of greater trochanter was 3.86 mm in group I and 0.59 mm in group II (p=0.01). Mean changes of neck-shaft angle was nearly the same, 3.57degrees in group I and 3.66degrees in group II. Complications were 15 cases in group I and 10 cases in group II. CONCLUSION Compressive hip screw with additional trochanteric stabilizing plate was effective surgical option in patients with femoral unstable intertrochanteric fractures in patients with more than 65 years old. It decreased lag screw sliding, lateral translation of greater trochanter and complication rates.
