BACKGROUND: The aim of study was to confirm the clinical effectiveness and results of wide and single anterior approach for fractures occurring along length of humerus. METHODS: A total of 23 patients with humeral fracture were enrolled into our study who were able to participate in at least one year of follow-up. Seven patients had segmental comminuted humeral fractures and 16 patients had distal humeral fractures. We made various tractions of the muscles to expose the proximal and the middle third humerus between the biceps and brachialis and the distal humerus by partial splitting of lateral side of biceps through a single incision. Postoperatively, we measured the Mayo elbow performance index (MEPI). RESULTS: we achieved bone union in all 23 patients. Solid union of the bone was achieved at an average 13.9 weeks. Postoperatively, two complications were observed screw loosening and nonunion. Revision surgery was performed in both patients. The patient with bone nonunion was treated using bone grafts. No postoperative infections or peripheral neuropathies were observed. At the final follow-up (average 20 months), we found that the average MEPI functional score of the patients was 91.7 points regardless of the fracture site. CONCLUSIONS: Our whole humerus with a single incision was effective for the treatment of segmental comminuted and distal fractures. we believe it is a useful alternative to preexisting methods of fracture fixation.

A clinical analysis of the septic hip was made on 15 patients, who had been undergone operation in Chung Nam National University Hospital from April, 1977 to Dec., 1978. The following results were obtained. 1. The ratio of male and female was 2.8:1. 2. The most common age group was 7~12 years (5 cases, 33.3%), and next common was 13–20 years (4 cases, 26.7%). 3. The most common causative microorganism was staphylococcus aureus(66.7%). 4. The most common duration of symptoms were less than 5 days (6 cases, 40%), and next common was 6~10 days (4 cases, 27%). 5. The patients, more than 10 days duration of symptoms, had late sequela in 80% but the patients, less than 10 days, had good prognosis in 80%. 6. In authors experience, the most effective treatment for septic hip was early diagnosis and hospitalization, followed by surgical decompression with specific antibiotics.

Articular cartilage have dual functions of shock absorber and bearing surface in a moving joint. Articular cartilage is avascular, so the chondrocytes in mature adult must receive their nourishment solely from synovial-fluid perfusion, and it is known that alteration of synovial-fluid perfusion causes degeneration of articular cartilage. Now, in orthopedic fields, the corrective cast immobilization and traction is in popular use. In order to study the cartilage changes induced by this long-term cast immobilization and traction, compression-immobilization and condylar resection of knee joint in rabbits were performed, and weekly histoiogic examinations of articular cartilage up to 5 weeks were followed. The observations were as follows: 1. Degenerative changes of articular cartilage were observed respectively with compression-immobilization and condylar resection, and the severity of the histologic changes appeared to be proportional to the duration of compression-immobilization and condylar resection. 2. Earlier degenerative changes of articular cartilage in condylar resection group than in compression-immobilization group were noted, and this earlier degenerative changes in condylar resection group suggests that hemarthrosis may play a role in cartilage degeneration. 3. Histologically unchanged calcific cartilage zone and mildly hypertrophied subchondral bone were noted in compression-immobilization group, but vascular invasion to calcific cartilage zone and subchondral osteoporosis were noted in condylar resection group.

On general principle, spondylolisthesis does not need surgical treatment but special features may arise in any such case to change the clinical picture and to indicate the necessity for operative intervention. There have been described a number of techniques and their combinations in the treatment of spondylolisthesis. Despitc continuing efforts to develop better techniques of lumber fusion, failure has been relatively common. In 1953, Watkins dcscribed a lateral approach to the transverse processes. Rombold recently described a lateral mass fusion of a single level for spondylolisthesis using extensive autogenous iliac grafts. He reported 96% roentgenographic fusion. It is the purpose of this paper to review a series of adults with symptomatic spondylolisthesis (16 cases) who were surgically treated by posterolateral fusion. 1. The site incidence of spondylolisthesis was 68.8%(11 cases) in L-5, 25%(4 cases) in L-4 and 6.2% (1 case) in L-4 & L-5. 2. Satisfactory resutts according to Gills criteria was 94% (15 cases). 3. In follow-up study, the younger the adult, the better the clinical results. 4. The fusion rate of intervertebral joint in roentgenographic finding was 100%. 5. There were no significant differences in duration and result of solid fusion between cases applied with hip spica cast and lumbosacral back brace or Norton-Brown brace.

The intraosseous ganglion is a rare cystic lesion of bone most frequently located in the subchondral epiphysis of long bones with or without direct communication with a joint cavity. This case is reported to call attention to this lesion which deserves consideration in the differential diagnosis of solitary cystic lesions of bone. We were reported a 59-aged woman without direct communication with the knee joint and osteoarthritis which was treated with the curettage and chip-bone graft.

Paget's disease is a disorder of middle or older aged persons in which abnormal osteoclastic and osteoblastic activity spontaneously occurs within the affected portion of any particular bone or bones. This causes a gradual gross structural alteration through continuous remodeling. The occurance of Pagets disease is extremely rare in China, Japan, Middle East, and Africa. We have experienced one case of Paget's disease of bone affecting the spine and femur, which is reported in this paper with brief review of literature.
