PURPOSE The purpose of this study was to compare the characteristics and clinical features of greater tuberosity fractures with or without a shoulder dislocation. MATERIALS AND METHODS A total of 108 cases of greater tuberosity fractures (56 cases with shoulder dislocation, 52 cases without shoulder dislocation) were reviewed retrospectively. Age, sex, side, injury mechanism, fracture displacement, fracture morphology, number of fracture fragments, main fragment size, treatment, and combined injuries were investigated. RESULTS The age, sex, side, injury mechanism, treatment, and combined injuries were similar in both groups (p>0.05). A statistically significant difference in fracture displacement, fracture morphology, number of fracture fragment, and main fragment size was observed between the two groups (p < 0.05). CONCLUSION In greater tuberosity fractures with a shoulder dislocation, the prevalence of fracture displacement was high and the depression type of fractures occurred frequently. In addition, the number and size of the fracture fragment increased. Therefore, an understanding of these fracture patterns will be helpful for deciding treatment and prognosis.
PURPOSE To evaluate the results and efficacy of posterior dual plating for distal shaft fractures of the humerus. MATERIALS AND METHODS We retrospectively analyzed 12 patients, who underwent open reduction and internal fixation using posterior dual plating for distal shaft fractures of the humerus, between July 2007 and July 2015, with at least 6 months of follow-up. After locating the radial nerve without dissection via posterior triceps splitting, the fracture was stabilized using a short 3.5 mm locking compression plate. Then additional fixation, using a long 3.5 mm locking compression plate, was performed. The clinical outcomes were assessed in accordance with the Mayo Elbow Performance Index (MEPI) scoring system, and the radiological outcomes were assessed using serial plain radiographs. RESULTS Eleven patients (91.7%) had bony union, and the mean union period was 13.9 weeks. In one patient, delayed union was treated by autogenous iliac bone graft at 8 months after surgery, which resulted in bony union. The mean MEPI score was 95.8, and the clinical outcomes were excellent in 9 patients and good in 3 patients. Postoperative complications included 1 elbow stiffness by heterotopic ossification and 1 temporary radial nerve palsy. One patient with temporary radial nerve palsy was completely recovered within the first 4 days after surgery. CONCLUSION Posterior dual plating for distal shaft fractures of the humerus revealed satisfactory clinical and radiological outcomes. It can be a useful alternative to provide stable fixation without the need for a dissection of the radial nerve.
Fracture of the lateral humeral condyle is a relatively common injury in children. It is an itraarticular fracture involving the growth plate so, the treatment should be done very carefully to reduce aditional damage and complication. The authors analyzed 34 fractures of the lateral humeral condyle in children who were treated from Mar. 1993 to Feb. 1998, to know the releationship between the factors affecting the development of complications and the results. The results were summerized as follows ; 1. There were 1 case (2.9 %) of Milch type I and 33 cases (97.1 %) of Milch ype II, and according to Jakob' stage, 9 case (26.5 %) of stage I, 19 cases (55.9 %) of stage II, and 6 cases (17.6 %) of stage III. 2. They were treated with cast immobilization in 5 cases (14.7 %), with closed rduction and percutaneous K-wire pinning in 8 cases (23.5%), and with open reduction and K-wire fixation in 21 cases (61.8%). 3. According to the criteria of Hardacre, the result of 5 cases of cast immobilization were excellent, 8 cases of closed reduction and percutaneous K-wire pinning were 3 excellent, 4 good, 1 poor, and 22 cases of open reduction and K-wire fixation were 19 excellent, 2 good, so there were 22 cases (64.7%) excellent, 11 cases (32.4%) good, and 1 case (2.9%)poor. 4. The complications were 11 cases (32.4%) of bony spur, 6 cases (17.6%) of overgrowth of the lateral condylar or capitellum, 1 case (2.9%) of premature epiphyseal fusion, and 2 cases (5.9%) of pinning site infection.

The tibial plateau fracture often produce some disabilities of the knee joint because it is the intraarticular fracture and often associated with soft tissue, ligament and meniscal injury. The authors analyzed 42 cases of the Tibial Plateau fractures, which were treated at the department of orthopaedic surgery, Seoul Adventist Hospital from 1992 to 1997, to know the releationship between the type of fracture, the methods of treatment, and the results. The results were summerized as follows; 1. The most common fracture type by Schatzker classification was type I(18 case 42.9%). 2. Sixteen cases among of 42 cases were treated with conservative treatment, and 26 cases were treated with operative method 3. The clinical result according to Blokker method, acceptable were 34 cases (81.0%) and unacceptable were 8 cases (19.0%) 4. The complications were limitation of range of motion(4 case), peroneal nerve palsy(2 case), posttraumatic arthritis(1 case), wound infection(1 case).
