Purpose This study examined whether preoperative radiological evaluations can predict syndesmotic instability according to the lateral malleolus fracture pattern in supination-external rotation-type ankle fractures. Materials and Methods This study enrolled 132 patients (132 ankles) with supination-external rotation stage 3 and 4 ankle fractures. Three-dimensional computed tomography was used for the morphological classification of the lateral malleolus fractures. A long oblique fracture was defined when the posterior cortical bone height of the fracture was 4.5 cm or more from the plafond of the distal tibial articular surface. A short oblique fracture was defined when the height was less than 4.5 cm. The demographic characteristics and syndesmotic instability of the two groups were evaluated. Results Short oblique fractures were confirmed in 102 cases, and long oblique fractures were confirmed in 30 cases. Long oblique fractures occurred at a statistically significantly higher incidence in younger ages and among males compared to short oblique fractures. Syndesmotic instability was more common in long oblique fractures. Conclusion In supination-external rotation-type ankle fractures, syndesmotic instability was observed in approximately 13%. Specifically, when the fracture pattern of the lateral malleolus is long oblique, the incidence of syndesmotic instability is approximately three times higher than in short oblique fractures. Therefore, meticulous evaluations of the lateral malleolus fracture pattern and establishing an appropriate treatment plan before surgery are crucial.
Purpose Patients with diabetes are known to have poor clinical outcomes due to the high incidence of complications after ankle joint fracture surgery. This study reports the clinical and functional outcomes based on glycemic control status among patients with ankle joint fractures who underwent surgical treatment. Materials and Methods Among patients who underwent surgical treatment due to ankle joint fractures from January 2015 to October 2019, 253 patients with a minimum follow-up of 12 months were identified. We divided them into 3 groups: 195 patients with no diabetes (Group A), 26 patients with well-controlled diabetes (Group B), and 32 patients with uncontrolled diabetes (Group C). In addition, patients with lateral, medial malleolar, bimalleolar, and trimalleolar fractures were identified using radi-ography. The functional outcome measures used for evaluation were the Revised Foot Function Index (FFI), Short Musculoskeletal Function Assessment (SMFA), and the Foot and Ankle Outcome Score (FAOS). Results Bone union at 3 months after surgery was high in Group A, showing significant differences compared to the other groups. There was a significant difference between the groups in the incidence of arthropathy and one or more complications. However, the FFI, SMFA, and FAOS did not show significant differences between the groups. Conclusion The incidence of complications was high in patients with uncontrolled diabetes compared to the patients with well-controlled diabetes and those with no diabetes. However, functional outcomes showed no significant difference.
This paper reports the use of a traction device for the treatment of neglected proximal interphalangeal fracture dislocations. A 44-year-old man with a fracture dislocation of a right ring finger proximal interphalangeal joint was admitted 17 days after the injury. Closed reduction and external fixation were performed using a dynamic traction device and C-arm under a brachial plexus block. Passive range of motion exercise was started after two weeks postoperatively and active range of motion exercise was started after three weeks. The traction device was removed after five weeks. No infection occurred during the traction period. No subluxation or displacement was observed on the X-ray taken two months postoperatively. The active range of motion of the proximal interphalangeal joint was 90°. The patient was satisfied with the functional result of the treatment with the traction device. The dynamic traction device is an effective treatment for neglected fracture dislocations of the proximal interphalangeal joint of a finger.
Transarterial embolization is accepted as effective and safe for the acute management in hemodynamically unstable patients with pelvic ring injury. However, transarterial embolization has potential complications, such as gluteal muscle/skin necrosis, deep infection, surgical wound breakdown, and internal organ infarction, which are caused by blocked blood flow to surrounding tissues and organs, and many studies on the complications have been reported. Here, we report an experience of the management of gluteal necrosis and infection that occurred after transarterial embolization, with a review of the relevant literature.
A pseudoaneurysm is a contained arterial disruption in the intimal and medial layers of an arterial wall. It may originate from a perforation caused by traumatic or iatrogenic injury or the dehiscence of a surgical anastomosis. Because of its insidious onset and delayed presentation, orthopaedic surgeons should be aware of the possibility of such a lesion after an initial trauma. We report on a case of a delayed huge pseudoaneurysm of the popliteal artery that occurred 11 months after conservative treatment of a supracondylar fracture of the femur in order to keep in mind the possibility of the delayed presentation of vascular injury after a distal femur fracture.
PURPOSE We compared visible blood loss and calculated blood loss after intramedullary fixation in intertrochanteric fracture, and evaluated correlation between blood loss and its risk factors. MATERIALS AND METHODS A total of 256 patients who underwent closed reduction and intramedullary fixation in femoral intertrochanteric fracture between 2004 and 2013 were enrolled in this study. The total blood loss was calculated using the formula reported by Mercuiali and Brecher. We analyzed several factors, including fracture pattern (according to Evans classification), gender, age, body mass index (BMI), anesthesia method, cardiovascular and cerebrovascular disease, preoperative anemia, American Society of Anesthesiologists (ASA) score and use of antithrombotic agents. RESULTS Total calculated blood loss (2,100+/-1,632 ml) differed significantly from visible blood loss (564+/-319 ml). In addition, the blood loss of unstable fracture patient was 2,496+/-1,395 ml and multivariate analysis showed a significant relationship between blood loss and fracture pattern (p<0.01). However, other factors showed no statistically significant difference. CONCLUSION Total calculated blood loss was much greater than visible blood loss. Patients with unstable intertrochanteric fracture should be treated with care in order to reduce blood loss.
PURPOSE To evaluate the results of using minimally invasive reduction techniques in patients with femoral subtrochanteric fracture. MATERIALS AND METHODS We retrospectively analyzed 40 patients (41 cases) with subtrochanteric fracture who underwent using minimally invasive reduction techniques. The mean age was 61.4 years (15-89 years), and the mean follow-up period was 32.7 months (12-66 months). Clinical results were assessed using the Parker-Palmer mobility score and the Salvati-Wilson hip functional score. Radiographic results were evaluated using bone union time and femur neck-shaft angle. RESULTS No significant difference was observed in the pre- and postoperative Parker-Palmer mobility score. Salvati-Wilson hip functional score showed more than good grade in 37 cases (90%) at the last follow-up. Union was achieved in all 41 cases at an average of 22.5 weeks (18-30 weeks). The mean femoral neck-shaft angle immediately postoperatively was 128.8 degrees (120-140 degrees), and the mean difference versus contralateral sides was 2.5 degrees varus (-6-13 degrees). CONCLUSION Fixation of femoral subtrochanteric fracture using minimally invasive reduction techniques showed excellent clinical and radiographic results and low complication rate.

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.

Fractures of the femoral shaft with marked bowing face some obstacles in fixation of the fracture such as difficulty in insertion of the intramedullary nail (IM nail) or exact contouring plate. Locking compression plates (LCP) are an option to manage this problem. However, we experienced consecutive breakage of LCP twice and IM nail once in an 80-year-old female. Finally, union of the fracture was achieved after fixation of the IM nail and additional plate together. Fractures of the femur shaft with marked bowing are thought to have different biomechanical properties; therefore, we present this case with a review of the literature.

PURPOSE To evaluate the clinical outcomes of operative treatment using a transolecranon approach with a dual locking plate for unstable intercondylar fractures of the distal humerus. MATERIALS AND METHODS Eighteen patients were followed for more than 1 year after surgical treatment for unstable intercondylar fractures of the humerus. Anterior transpositioning of the ulnar nerve and an early rehabilitation program to allow range of motion (ROM) exercise from postoperative week 1 were used for all cases. The clinical and functional evaluation was performed according to the Mayo Elbow Performance Index and Cassebaum's classification of ROM. RESULTS The range of elbow joint motion was a flexion contracture mean of 12.8 degrees to a further flexion mean of 119.3 degrees at the final follow-up. The Mayo Elbow Performance Index was an average of 88.5 points. Among the results, 6 were excellent, 9 good, 2 fair, and 1 poor. Therefore, 15 cases (83.3%) achieved satisfactory results. Fourteen cases (77.7%) achieved a satisfactory ROM according to Cassebaum's classification. All cases achieved bone union, and the interval to union was an average of 14.2 weeks. CONCLUSION Dual locking plate fixation through the transolecranon approach seems to be one of the effective treatment methods for unstable intercondylar fractures of the humerus because it enables the anatomical reduction and rigid fixation of articulation, and early rehabilitation exercise.
Multiple non-contiguous spinal fracture is a special type of multi-level spinal injury, which is rare but most frequently occur in motor vehicle accident or a falling from a height. We report five patients of multiple non-contiguous spinal fractures. All patients underwent segmental pedicle screws fixation without fusion for preserving facet joints and minimizing blood loss and operation time. We performed necessary operation for any concomitant injuries at the same day.
PURPOSE To evaluate the clinical and radiologic results of the arthroscopic treatment using TightRope(R) (Arthrex, Inc, Naples, FL) for management of acute acromioclavicular dislocation. MATERIALS AND METHODS Twelve patients with acromioclavicular joint dislocation Rockwood type V are underwent the arthroscopic acromioclavicular joint reconstruction using TightRope(R) between March, 2008 and March, 2009. The average age was 40.4 years (range 25~63 years) and mean follow-up was 10 months (range 8~16 months). The shoulders were evaluated using parameters include radiologic measurements by comparing the clavicle posteroanterior and lateral radiographs with the contralateral one. Clinical evaluation was made for pain, function, and range of joint motion by Constant score and KSS (Korean Shoulder Score). RESULTS All twelve patients returned to their work without pain in 3 months after operation. The average Constant score and KSS score was 98.4 (range 97~100) and 97.8 (range 97~100) at the last follow-up. Because of technical error and indication error, two patients showed failures of TightRope(R) fixation on the coracoid side and the acromioclavicular joint was redislocated, so these cases were excluded. 10 patients were satisfied with functional results and cosmetic appearance. CONCLUSION Considering its less morbidity, less hospitalization, excellent cosmesis, early rehabilitation, this new technique offers an attractive alternative in acromioclavicular joint stabilization if the early technical error would be overcome.

PURPOSE To compare anthropometric indicators around the hip between osteoporotic fracture group and control group. MATERIALS AND METHODS Thirty patients for osteoporotic hip fracture and the same number of patients for spine fracture who admitted our institute from November 2006 to March 2007 were matched with control patients without osteoporotic fracture. The waist circumference (WC), hip circumference (HC), thigh circumference (TC), and height were measured. From these measurements, waist to hip ratio (WHR), waist to thigh ratio (WTR), hip to thigh ratio (HTR), waist to height ratio (WHtR), hip to height ratio (HHtR), and thigh to height ratio (THtR) were calculated. All these indicators were compared between hip fracture and control group, and between spine fracture and control group. RESULTS Comparison between spine fracture and control group showed that the WC, WHR, WHtR were statistically significant, but all indicators failed to show accuracy in the ROC analysis. Comparison between hip fracture and control group demonstrated the TC, WTR, HTR, WHtR, HHtR, THtR were statistically significant. However, only the HTR showed fair accuracy in the ROC analysis. The area under the curve (AUC) of the HTR was 0.75 (95% confidence interval, 0.62 to 0.87) (p=0.001). CONCLUSION The HTR was fairly accurate in predicting the incidence of hip fracture compared with any other anthropometric indicators. Therefore, we can consider that the HTR has clinical usefulness.
PURPOSE To perform comparative analysis between the results of internal fixation and hemiarthroplasty in unstable intertrochanteric fracture of osteoporotic bone. MATERIALS AND METHODS From February 2003 to February 2006, 36 patients treated surgically for unstable intertrochanteric fractures were evaluated. The patient's age was older than 70 year old; the T-score of preoperative bone mineral density (BMD) was lower than -3.0; they were followed up for more than 1 year. The patient were divided into two groups. One group was treated with dynamic hip screw or proximal femoral nail (Group A, 23 cases), and the other group was treated with bipolar hemiarthroplasty (Group B, 13 cases). The two groups were compared in terms of hip joint function using Clawson classification and radiologically. RESULTS Nonunion and fixation failure happened in 6 cases (26%) of gruop A. However, all patients in group B showed stable maintenance of implant. Recovery of hip joint function was found in 13 cases (43%) of group A, whereas 12 cases (93%) of group B recovered. CONCLUSION Nonunion and failure of fixation happened more frequently in internal fixation than bipolar hemiarthroplasty, and the postoperative hip joint function was better in bipolar hemiarthroplasty than internal fixation. Therefore, bipolar hemiarthroplasty might be better operative treatment for unstable intertrochanteric fracture of osteoporotic bone.

PURPOSE To compare the clinical and radiological results after surgical treatments of the avulsion fractures of ACL between children and adults. MATERIALS AND METHODS 40 cases (18 cases of children, 22 cases of adults), who underwent surgical treatments after avulsion fractures of the ACL and followed up more than one year, were enrolled. Fractures were classified by modified Meyers & McKeever criteria. Range of motion, LK score, Lachman test, Pivot-Shift test, quadriceps muscle atropy and Telos® stress arthrometer were compared. RESULTS The types of fracture in children were categorized into 8 cases of type II, 10 cases of type III, and 2, 15, 5 cases of type II, III, IV each in adult group. Mean LK score showed significant difference between 99.3 points in children and 89.5 points in adults (p<0.05). In addition, accompanied injuries and the high degree of fracture leaded low LK score. However, there was no significant difference in range of motion, Lachman test and Pivot-Shift test. Anterior laxity by Telos® device showed an average of 2.0 mm in children, 2.5 mm in adults (p>0.05). CONCLUSION Children group showed better treatment results of avulsion fracture of ACL. Higher incidence of type II fractures and less combined injuries considered to be factors for better results.

PURPOSE To compare the results of open fixation and closed percutaneous pinning in managing Jakob stage II lateral condylar fractures of children's elbow. MATERIALS AND METHODS Since Febuary 2000, We operated 21 children with Jakob stage II lateral condylar fractures of elbow. Eleven of the 21 were treated with closed percutaneous pinning, open fixation was done to the other 10 children. Each patient was evaluated about range of motion, carrying angle, scar satisfaction and radiologic findings for comparison between closed pinning and open fixation groups. RESULTS Open fixation group showed 3.8 degrees decrease of elbow motion while closed pinning group showed no significant decrease. Carrying angle and radiologic findings were not different between the two groups. Open fixation group expressed dissatisfaction to their scars (average 5.2 cm) whereas all the patients of closed pinning group were satisfied with their functional and cosmetic outcomes. CONCLUSION In managing Jakob stage II lateral condyle fractures of children's elbow, closed percutaneous pinning was thought to be superior to open fixation because of the same functional outcome and much better cosmetic results.
Traumatic posterior hip dislocation should be reduced emergently, but diagnosis could be delayed in a patient with head trauma or in developing countries. We have experienced neglected posterior hip dislocation for three months in a crutch-walking patient who had ipsilateral tibia fracture and alert mentality. Open reduction followed by six-weeks skeletal traction was performed. At one year follow-up, the reduced hip showed good range of motion with no evidence of avascular necrosis.
PURPOSE To evaluate and report the clinical result of the intramedullary fixation by threaded Kirschner wire in the clavicle shaft fracture. MATERIALS AND METHODS From May 2000 to April 2004, twenty patients who had the fracture of the shaft of the clavicle were treated by the intramedullary fixation with threaded Kirschner wire. Thirteen patients were followed up and the clinical and radiological results were analyzed. RESULTS All of the cases had satisfactory fracture union but there were four cases of skin irritation signs by the tip of threaded Kirschner wire. In one case, the Kirschner wire was bent at the fracture site with malunion. According to the clinical scoring system of Kang et al, eight cases were excellent and five cases were good. CONCLUSION Authors think that intramedullary fixation with threaded Kirschner wire in the fracture of the shaft of the clavicle is one of a good operative method because of small operative incision, easy operative method, satisfactory fracture union and easy removability of the implant.
Fat embolism is a rare complication of multiple long bone fracture or extensive soft tissue injury. The pathogenesis of fat embolism has been poorly understood and definite pathogenesis and treatment were not fully established. Respiratory failure associated with fat embolism is a major cause of death, but is usually self-limited, and is responsive to intensive treatment. We have experienced fat embolism in cancellous bone fracture which occurred in spine, distal radius and talus. Patient's fractures were treated with conservative management. The patient was recovered from fat embolism with supportive treatment.

PURPOSE To evaluate the differences of associated factors in thoracolumbar fractures according to the mechanism of injury, level and type of the fracture, associated injuries were investigated for comparison between injuries by fall from height and by in-car accident injury. MATERIALS AND METHODS Medical records and X-ray findings of 249 patients with fractures of thoracolumbar spine were reviewed retrospectively. Among them, 169 patients were injured by the two main causes. McAfee classification was adopted to determine the type of fracture. Associated injuries were classified as head and neck, chest and abdomen, pelvis, proximal and distal extremity, and neurologic deficit. Statistical analysis using Chi-square method was used for comparison between the two groups. RESULTS In overall patients, the most common cause of thoracolumbar fracture was fall from height (44.6%) followed by in-car accident (23.3%) and fall down (16.9%). In fall-from height gruoup, burst fracture was the most common (44.1%) while flexion-distraction injury was the most popular (39.7%) in in-car accident group (p=0.05). Comparison according to height of fall showed significant increase of multiple fractures (p=0.0326). Associated injuries of distal lower and upper extremities and pelvis were common in fall-from-height group, while injuries of head and neck, proximal part of upper extremity, chest and abdomen were common in in-car accident patients. CONCLUSION Type of fracture and distribution of associated injuries were significantly different between the two main causes of thoracolumbar injury, which seemed to be useful for understanding the mechanical events of injury and detecting associated injuries in each victim.

PURPOSE To evaluate treatment results between internal and external fixation groups in two-stage reconstruction of infected nonunion of long bones using antibiotics-impregnated cement beads. MATERIALS AND METHODS In the first stage, preexisting hardwares were removed and radical debridement was done. The dead space was filled with antibiotics -impregnated cement beads and the nonunion site was immobilized by external fixation, cast or skeletal traction. In the second stage, all cases were divided into two groups; the nonunion was fixed by internal fixation in group I versus external fixation in group II. The intervening period between the first and second stage was average 8.7 weeks (range, 3~23 weeks). RESULTS The follow-up period was average 45 months (range, 16~71 months). Infection control and bone union were achieved in all 13 cases of group I. Infection recurred in two of 28 cases in group II, one underwent above-knee amputation and the other case was lost in follow-up. The mean number of supportive operations including repeated curettage, augmentation and change of infected pins, angular correction, and soft tissue flap was average 2 and 6.2 times respectively in group I and group II. Bony union period was average 19.3 and 23.1 weeks in each group. According to Paley's classification, group I was similar to group II in bony and functional result (p>0.05). CONCLUSION Antibiotics-impregnated cement beads provided positive effect on infection control. Internal fixation group showed less number of additional operations and earlier bony union than external fixation group.

PURPOSE To assess diagnostic efficacy of the MRI in thoracolumbar fractures, especially in changes of bone and soft tissue which cannot be documented by other diagnostic tools. MATERIALS AND METHODS Among 85 patients managed for thoracolumbar fractures between January 1997 and June 2003, MRI was performed in 30 patients to get more informations. Plain X-ray, CT and MRI of these cases were reviewed retrospectively by two orthopaedic spine surgeons and one radiologist to investigate the informations which only MRI could afford. RESULTS 14 (46.7%) among 30 patients had occult fractures of vertebrae other than main fracture which had not been diagnosed as fractured. Besides 6 patients who showed distraction of posterior structure on plain X-ray, injury of posterior ligament complex was confirmed by MRI in 12(40%) patients. Additionally, MRI visualized other soft tissue injuries such as intramuscular and subcutaneous hematoma, changes of the spinal cord and intervertebral disc. In 16 among 30 patients, informations achieved from MRI were the most important factors in deciding treatment modality. CONCLUSION MRI seems to be efficient in visualizing not only soft tissue injury such as ligament but also occult fractures of additional vertebra in thoracolumbar fractures, therefore MRI seems to be an important diagnostic tool in decision of treatment modalities, especially in cases of uncertain stability.

Avulsion fracture of the calcaneal tuberosity is an uncommon injury. Usually it occurs from indirect trauma, and can be seen in old patients with osteoporosis or in patients with diabetic neuropathy. Follow-up studies showed fracture healing in most cases, but skeletal deformity may develop in some cases. Therefore we should do plain X-ray evaluations in diabetic patients with foot and ankle pain, even though there have been no definite trauma history. Four cases of calcaneus avulsion fracture were treated operatively in diabetic patients, and reported.

PURPOSE To evaluate the surgical results between fixations by antibiotic-cement loaded intramedullary nailing and antibiotic-cement loaded external monofixator in the treatment of infected nonunion of long bone shaft with mild bone loss and shortening of less than 1 cm. MATERIALS AND METHODS Among the 15 cases of infected nonunion of long bone shaft, 6 cases treated with fixation by antibiotic-cement coated intramedullary nailing and 3 cases treated with fixation by intramedullary nailing along with antibiotic-cement beads insertion were divided as group I (n=9), and other 6 cases treated with fixation by external monofixator along with antibiotic-cement beads insertion were divided as group II (n=6). There was no difference between the two groups in the degree of infection in the laboratory data and clinical feature and degree of bone loss and shortening. Male was in 7 and 5 patients, average age of the patients was 34.8 (26~53) and 37.2 (20~63) years old and average follow-up period was 15.9 (12~35) and 19.3 (15~41) months in group I and II respectively. RESULTS Among the nine cases of group I, 3 cases were newly convereted into fixation by antibiotic-cement coated intramedullary nailing at average 9.5 weeks. Radiologic union was gained at the average of 26 weeks from the time of initial nail fixation. Infection was responsive at 6.1 weeks by laboratoey data. Knee ROM of more than 100 degrees was gained in all case and average shortening was 9.2 mm in the last follow-up. And external rotation deformity of more than 5 degrees was noted in 1 case. Among the six cases of group II, radiologic union was gained at 14 weeks in 1 case without converting to internal fixation, and the other 5 cases were converted to antibiotic cement loaded intramedullary nailing at average 12.5 weeks because of delayed uinon or angulation deformity, and radiologic union was gained at average 44 weeks from the time of fixation by external fixator. Infection was responsive at 10.2 weeks by laboratoey data. Knee ROM of more than 100degrees was gained in 5 cases, and average shortening was 11.8 mm in the last follow-up. CONCLUSION In the treatment of infected nonunion of long bone shaft with mild bone loss and shortening of less than 1 cm, the fixation by intramedullary nailing with the use of antibiotic-cement prefers to the fixation by external monofixator with the use of antibiotic-cement in the velocity of union, control of infection, and in the clinical aspects such as alignment, early ambulation and joint stiffness.
PURPOSE To establish the guidelines for the differential diagnosis and proper initial treatment of the gas forming infections through the review of literature and our clinical experiences. MATERIALS AND METHODS The radiological findings, clinical course, gram stain, bacterial culture, predisposing factors and treatment of four cases of gas forming infections from January 1994 to August 2001, were retrospectively analyzed. RESULTS Three cases diagnosed presumptively as gas gangrene were improved through amputation or disarticulation and intravenous antibiotics. One case diagnosed presumptively as non-clostridial infection was expired due to sepsis in spite of incision, drainage and intravenous antibiotics. In the bacterial culture, two cases were non-clostridial infection, one case was not able to diagnose and one case was clostridial myonecrosis(gas gangrene) CONCLUSION: The gas forming infections are rare but life-threatening. When the proper initial treatment is delayed, the fatal complications may result. So, the presumptive diagnosis through gram stain, clinical course, radiological findings should be made as soon as possible, and according to which, the appropriate initial treatment, such as, surgical debridement, amputation, intravenous antibiotics must be started. The following treatments should be corrected by definitive diagnosis through the bacterial culture.

PURPOSE The aims of this study were to investigate the prevalence and the causes of screw breakage in tibia nailing. MATERIALS AND METHODS Between 1995 and 2000, eighty-two tibial diaphyseal fractures were treated with interlocking nails. The loss of follow-up was 7 cases. We retrospectively reviewed seventy-five cases. We investigated the rate and location of metal failure and evaluated the fracture pattern, the presence of distraction after nailing and union abnormality. RESULTS Screw breakage was identified in seven cases (9.3%) and most frequently occurred on the second proximal locking screw. Screw breakage occurred in AO type B or C type fractures, fracture site distraction after nailing, open fracture, delayed union and nonunion. CONCLUSION The main cause of screw breakage is unstable bone to bone contact on the fracture site caused by comminution or distraction. The open fracture, delayed union, and nonunion also contributing factors for screw breakage. For preventing screw breakage, it is necessary to avoid fracture site distraction and delay full weight bearing in cases having unstable fracture site contact.

PURPOSE To investigate the effect of defatted safflower seed or matairesinol on spontaneous bone formation in surgically induced bone defects in young rabbits MATERIALS AND METHODS: Bone defects(20% of original femoral length) were created at the midshaft of the femur in 52 young rabbits and stabilized with external fixation. The periosteum was preserved. Fifty-two rabbits were divided into four groups as follows; the group I fed on safflower seed powders(30%) and normal diet(70%), the group II on matairesinol (5%) and normal diet(95%), the group III on normal diet(100%) with intravenous injection of matairesinol, the group IV on normal diet(100%). Radiographs were taken weekly to evaluate the bone regeneration and union time. Biomechanical testing on the new bone formation area was performed to measure bending stiffness. The area of new bone formation was scanned by quantitative computed tomography to measure bone mineral density(BMD). RESULT The mean union time(weeks) was 7.2 in the group I, 8.6 in the group II, 8.8 in the group III, and 8.5 in the group IV and was significantly different between the group I and the other groups(p<0.05). The BMD and bone strength of the callus were compared between the group I and the group IV. The mean BMD was 310.45 +/-49.58 g/mm2 in the group I and 291.16 +/-55.79 g/mm2 in the group and there was significant difference(p<0.05). The mean bending stiffness was 415.33 +/-137.18 N/mm in the group I and 358.75 +/-107.32 N/mm in the group IV and there was significant difference(p<0.05). CONCLUSION The diet with safflower seed powder was effective for decreasing union time and increasing bone strength of the callus formed at the bone defect whereas the diet or injection with matairesinol was not effective. More experimental studies are necessary to prove the effect of matairesinol on the callus.
