It has been generally agreed that most fractures of the humeral shaft are best treated non-operatively although occasionally there are indications for primary operative treatment. Recent advances in internal fixation techniques and instrumentation have led to an expansion of surgical indications, and operative treatment produces higher rates of nonunion, infection and other associated complication when compared with closed treatmet techniques. Because of the significant morbidity of the operative treatment, closed intramedullary fixation techniques that provide stability of the fracture site without opening and reduce the postoperative complications, were developed. In this paper we document forty two fractures of the humeral shafts that were treated by functional bracing(Group I: 24 cases) and intramedullary fixation with functional bracing(Group II: 18 cases) between October, 1982 and August, 1986. And the obtained results were as follows: 1. The everage healing time was 9 weeks in the Group I, and 11 weeks in the Group II . 2. The non-union has not been encountered in the Group I, but non-union and delayed union were 4 cases (22.2%) in the Group II. 3. The complication rate was 9 cases(37.5%) in the Group I, and was 12 cases(66.7%) in the Group II, but deep infection did not occured in all cases. 4. The residual angulation more than 5 degrees was 20 cases(83.3%) in the Group I, and was 2 cases(11.1%) in the Group Il. However the results of the group Il were inferior ot the group I, of more proper selection of the patients, more accurate technique and adequate type of nails have been used, the better results will be taken.

The thoracolumbar spine is relatively easily traumatized and result in serious complications such as neurologic impairment and instability, so its proper management is very important. Formerly the thoracolumbar spine injury was evaluated mainly by plain radiographs, and tomograms if indicated,but because computed tomography visualizes bone and soft tissues three-dimensionally, we tried to compare its value with that of plain radiographs in potentially unstable thoracolumbar injuries. From January 1984, we determined the stability of the potentially unstable thoracolumbar spine injury according to computed tomography finding and compared with plain radiography finding, and the following results were obtained. 1. By Holdsworth classification, it was difficult to determine the stability of the thoracolumbar spine injury. 2. In cases of compression fracture and burst fracture by Denis classification, it was necessary to determine the stability by computed tomography. 3. In cases of unstable burst fracture by McAfee classification, there was no direct relationship between the degree of canal occlusion and neurological deficit, but above 25% in conus medullaris lesion and above 50% in cauda equina lesion usually manifested neurological deficit. 4. In our cases, the neurological status of initial injury was important factor to determine the improvement rate.

We experienced a rare case of thoracic outlet syndrome caused by hypertrophic nonunion of the first rib. A diagnosis was made mainly upon provocative tests and imaging studies. Pain and tingling could be reproduced and the radial pulse obliterated by the hyperabduction test. Abundant callus formation on the posterior aspect of the first rib with fracture line was visible on plain radiograph. Two-dimensional computed tomography showed right thoracic outlet narrowing mainly caused by the mass-effect of the callus. Dynamic arteriographic studies revealed an external compression of the right subclavian artery and duplex ultrasonography demonstrated a reduction in right subclavian artery blood flow when the shoulder is in 90 degrees of abduction. Surgery was performed after the conservative management for three months which failed to relieve the patient of his complaints. Resection of the first rib via transaxillary approach was undergone uneventfully in combination with the myotomy of the scalenus anticus muscle. At postoperative one year follow up, the patient was free of symptoms, and had a full range of motion of the right shoulder with no evidence of arterial insufficiency.

PURPOSE: To clinically and radiologically assess cemented total knee arthroplasty. MATERIALS AND METHODS: Among the patients with rheumatoid arthritis or degenerative arthritis treated at the Department of Orthopaedic Surgery of Pusan National University Hospital by cemented total knee arthroplasty between January 1990 and October 1992, 21 patients (22 knees) were followed up for more than 5 years. The Knee Rating Scale of Hospital for Special Surgery was used for the clinical assessment and the American Knee Society Roentgenographic Evaluation and Scoring System was adopted for the radiological assessment. RESULTS: The average preoperative knee rating score was 46.4 and improved to 83.2 at the latest follow up. The average range of motion was 88 preoperatively and 120 at the latest follow up in rheumatoid arthritis. In degenerative arthritis, it was 104 preoperatively and 115 at the latest follow up. Four of 22 knees had radiolucent lines at the bone-cement interface, but most of them were nonprogressive and clinically insignificant. In conclusion, cemented TKA can be indicated for the painful arthritic knees in old patients. Rheumatoid arthritis showed better improvement in HSS knee score and ROM than degenerative arthritis. But, similar results were shown in the radiological assessment of rheumatoid arthritis and degenerative arthritis. CONCLUSIONS: Even though cemented TKA for the painful arthritic knee has shown good results, long-term follow up studies will be required to determine both the long-term clinical results as well as the radiological results.

The purpose of this study is to compare 76 cases of fractures of the proximal humerus both clinically and radiologically which were treated at Pusan National University Hospital from January 1987 to December 1996. According to Neers classification, among the 76 patients, there were nine one-part fractures (11.8%), forty two-part fractures (52.6%), eighteen three-part fractures (23.7%), four four-part fractures (5.3%), and five head-splitting fractures (6.6%). In terms of treatment method, among the 76 patients, 49 patients (64.5%) were treated conservatively. Thirty seven patients (75.5%) of one-part and two-part fractures were treated conservatively, and twelve patients (54.5%) of three-part and four-part fractures were treated operatively. The results of the cases were rated by the Neer s assessment, 42 patients (85.7%) had excellent or satisfactory results in one-part and two-part fracture, and 7 patients (31.8%) had unsatisfactory or failed results in three-part and four-part fracture. Total cases with complications were 14 cases (18.4%). From the viewpoint of the type of fracture, the results in two-part and three-part fractures were much better than those of fourpart fractures. The joint stiffness which was the most common complication must be prevented by allowing the early motion of the joint to obtain a better result.
