PURPOSE To compare the clinical and radiologic outcomes of various surgical techniques for an isolated fracture of greater tuberosity of the humerus. MATERIALS AND METHODS From February 2001 to December 2008, 31 patients, who underwent an operation for isolated greater tuberosity fracture and were followed up for more than 1 year, were enrolled in this study. The mean age at the time of operation was 49.3 years (range, 23-73 years). The operation methods included in this study were as follows: a transosseous suture using nonabsorbable suture material (16 cases), a fixation by cannulated screws (10 cases), tension band wiring (2 cases), bony fragment excision with rotator cuff repair (2 cases), and percutaneous pinning (1 case). RESULTS At the last follow-up, the average Constant score was 79.4 and Korean Shoulder Score (KSS) was 81.2. Among the various operation methods used in this study, the transosseous suture had the highest scores with 82.5 in Constant score and 89.3 in KSS. Bone union was achieved at average 10.3 weeks (range, 7-15 weeks), and there were 2 cases in which the reoperation was required due to internal fixation failure. Postoperative shoulder stiffness occurred in 3 cases, and all the cases were done with the deltopectoral approach. CONCLUSION Clinically and radiologically satisfactory results were obtained using various operation techniques for an isolated greater tuberosity fracture of the humerus. The transosseous suture showed relatively better results than the other methods used in this study. To achieve favorable clinical and radiologic results, it is important to select an appropriate surgical approach and fixation method according to the fracture site, degree of displacement, and size of fragment.

PURPOSE To evaluate the relationship between radiographic parameters and clinical results after operative treatment of the displaced intra-articular calcaneal fractures. MATERIALS AND METHODS We analyzed 35 patients of unilateral displaced intraarticular calcaneal fractures who had operative treatment with minimum follow up of 1 year. At the last follow up, we measured the radiographic parameters including Bohler angle, Gissane angle, heel height, calcaneal length, talocalcaneal angle, talar declination angle, subtalar incongruity between normal and affected site. Clinical results were measured by Creighton-Nebraska Health Foundation Assessment Score (CNH). The correlation between the radiographic parameters and the clinical results were analysed by Pearson correlation method. RESULTS Among the all radiographic parameters we analyzed, only subtalar incongruity shows strong negative linear correlation with clinical results. The average difference of subtalar incongruity between normal and affected site was 0.54 mm (0~2.5) and the correlation coefficients with CNH score was -0.784 (p=0.002). CONCLUSION We suggest that the subtalar incongruity is significantly correlated with the clinical results after operative treatment of the displaced intraarticular calcaneal fractures.

PATIENTS & METHOD: Open reduction and internal fixation on patient with closed displacement ankle fracture over the age 60 years were studied in 51 cases. Statistical analysis by t-test was used to assess the factors affecting to the post-operation radiological results among the age, sex, classification of fracture, the degree of fracture displacement, bone fragility between anatomical reduction group and non-anatomical reduction group in average 16 months, RESULTS: There are statistical significance(p<0.05) of the sex and bone fragility in post-operation radiological results. CONCLUSION The radiological results in old age with ankle fracture is affected by sex and bone fragility in open reduction & internal fixation.
PURPOSE The current study was performed to evaluate the treatment and functional results of the three and four part fractures of proximal humerus. MATERIALS AND METHODS Nineteen patients with displaced 3 part and 4 part fractures and fractures-dislocation were followed for more than one year and analyzed. The causes of injuries, classification of fracture, associated injuries, functions, results of treatment and complications were investigated. RESULTS According to Neer's classification, there were 15 cases of 3 part fracture and 4 cases of 4 part fractures. The range of motion and functional results of the shoulder in 3 part fractures (flexion 138.6degrees , abduction 124.3degrees , Constant score 60.3) were better than 4 part fractures (flexion 77.5degrees , abduction 60degrees , Constant score 29.5). We compared the humeral offset of injured side with the healthy one. In the cases of less than 4mm difference, the range of motion was 150degrees in flexion and 40.3degrees i n abduction, and the constant score was 67.3. But in the cases of more than 4mm difference, the range of motion was 84.3degrees in flexion and 58.6degrees in abduction, and constant score was 30.9 points. Clinical results was better in the cases of less than 4mm difference. CONCLUSION Range of motion and functional results of 3 part fractures were better than 4 part fractures and restoration of humeral offset resulted in better clinical results.
PURPOSE We analyzed the anatomical results of operative treatment in acetabular fractures according to fracture pattern and surgeon's experience.
MATERIAL AND METHODS: From December, 1993 to December, 1999, 100 cases of acetabular fractures operated by single surgeon were analyzed. Fracture configuration was classified by Letournel's method. The anatomical results were classified by Matt' s criteria and Claude Martimeau score. RESULTS There were 36 elementary fractures(anterior column type: 4 cases, posterior wall type: 29 cases, transverse type: 3 cases) and 64 complex fractures(posterior wall and posterior column type: 4 cases, anterior and posterior hemitransverse type: 8 cases, transverse and posterior wall type: 16 cases, T type: 6 cases, both column type: 30 cases). According to Matta's criteria, all elementary fractures were seen anatomic or satisfactory results however, eleven cases of combined fracture were seen unsatisfactory results. Mean Claude Martimbeau's score was 6.1 point. Elementary fracture was 7.5 point and combined fracture was 5.4 point. Both column fracture was 4.4 point and it was the lowest point among the fractures. In both column fracture, the improvement of surgeon's skill made more good anatomical results. There were four cases of infection and 2 cases of nerve injury. CONCLUSION In operative treatment of acetabular fractures, complexity of fracture demands more appropriate surgical approach and skillful surgeon,

PURPOSE Monteggia fracture is a combination of ulnar fracture and radial head dislocation. Despite of low incidence, Monteggia fracture has a problem in the treatment. So satisfactory results could not be achieved easily. The purpose of this study was to analyze factors affecting functional results in Monteggia fracture. MATERIALS AND METHODS From January 1990 to June 1998, we retrospectively reviewed 24 patients out of 40 patients who had been treated for Monteggia fracture. The functional assessment was performed with Broberg and Morrey system10). RESULTS Excellent and good results were achieved in 16 cases(66.6%), whereas fair and poor results in 8 cases(33.4%). Satisfactory results were obtained in 66.6% overall.
According to the Bado classification, functional results were not different significantly between types. According to the mechanisms of injury, unsatisfactory results were obtained in 8 of 17 patients with high energy injury. Monteggia fractures with ulnar fracture at the diaphyseal level showed satisfactory results significantly compared to others. In terms of the methods of internal fixation, the plate and screw fixation showed satisfactory results in 14 of 16 patients whereas tension band wiring or intramedullary nailing showed unsatisfactory results in 6 of 8 patients. CONCLUSION In Monteggia fractures, factors affecting functional result may be the mechanism of injury, the level of ulnar fracture and the method of internal fixation.

PURPOSE : The purpose of this study is to detect the factors influencing the results of treatment for Lisfranc injuries of the foot. MATERIALS and METHODS : We assessed the correlation between the AOFAS Scale and each of the variables which might influence the results of treatment in 25 cases of Lisfranc injuries, using the SPSS version 7.5. RESULTS The mean AOFAS Scale rated 81.48 points. The degrees of initial soft tissue injury had close correlation with the AOFAS Scale; while time from injury to operation, accuracy of reduction such as the alignment of the tarsometatarsal joints, gap between the first and the second metatarsal bases, and the foot arch angles had moderate correlation with AOFAS Scale(p<0.05). The age at operation, types of fractures, joint space of the tarsometatarsal joints had little or fair degrees of correlation with the AOFAS Scale(p>0.05). CONCLUSION : The factorf influencing the results of treatment for Lisfranc injuries included initial deree of soft tissue injury, time form injury to operation, and variables related to the accuracy of reduction such as the alignment of tarsometatarsal joints, gap between the first and the second metatarsal bases, and the maintenance of the foot arch.
Forty-six patients who had had forty-nine calcaneal fractures were managed with closed reduction and a cast, closed reduction and axial pin fixation, and open reduction and internal fixation. The results were reviewed retrospectively, between twelve months and twenty-six months after the treatment, with criteria usued in assesssment of result by Salama30) and with plain radiographs. The purpose of this study were to analyze the relationship between the prognostic factors and post-treatment results. The results of treatment and prognostic factors obtained from this study were as follows. 1. The negative prognostic factors that were associated with an unsatisfactory out come were an age of more than fifty years, a greater body weight, work involving strenuous labor, subtalar incongruity, a decreased fibulocalcaneal space, and a decreased B hler-angle ratio of the fractured to the normal side. 2. Patients who had had a tongue-type fracture had a better result than those who had had a central depression fracture, while those who had had a central depression fracture had a better outcome than those who had had a comminuted fracture. 3. The length of the Achilles-tendon fulcrum, which is directly related to the calcaneal length, was not related to the outcome.

The intraarticular fractures of the distal tibia. so-called pilon fractures have been difficult in management due to the severe comminution of articular surface and frequent soft tissue problems. So there have been many controversies in the method of treatment. Although historically the results of various type of treatment of these fractures have been less than optimal, there has been a recent trend that suggests success in the majority of cases through operative treatment following the principles outlined by the AO/ASIF group. Among the patients of pilon fracture admitted to our hospital from October 1989 to August 1995 who were treated by open reduction and internal fixation, 32 patients(34 cases) were included who could be follow up for more than 2 years. According to AO/ASIF classification, type B1 5 cases, type B2 7 cases, type B3 5 cases, type C1 3 cases, type C2 4 cases, type C3 10 cases. The authors analyaed the clinical and radiological results of tibial pilon fractures exclusively treated by internal fixation.
The results as follow : 1. Among 34 cases, 12 cases(35.3%) were not associated with of fibula fracture. There was no stastical relationship between the severity of pilon fracture and the presence of flbula fracture.
2. Good results in fracture reduction was obtained at 26 cases(76.5%) and good functional reults was obtained at 26 cases(76.5%).
3. The most commom postoperative complication was infection combined with skin problem(6 cases), which were treated by antibiotics and flap surgery.
4. Anatomical reduction and stable internal fixation of articular surface, careful manipulation of soft tissues and early range of motion exercise yielded good results of surgical treatment of pilon fracture.
