Although the clavicle is probably the most commonly fractured bone, nonunions are rare. We experienced 19 cases of clavicle nonunions, trested at the Depatment of Orthopedic Surgery of Wonju Christian Hospital, between January 1980 and June 1988(seven years and six months). This study focused on predisposing factors in relation to nonunion of clavicle and treatment. The factors predisposing to nonunion were middle and lateral 1/3 of clavicle, primary open reduction, severe trauma with associated injury and persistent gross displscement of fregment. Among the 19 patients, 16 patients were treated with semitubular plating and iliac bone grafting, 2 patients with the resection of the distal fregment and one patient was treated with treated with K-wire fixation and bone graft. All patients achived good union by the postoperative 10.7 week on average and symptomes disappeared. It was concluded that symptomatic nonunion of the clavicle could be trested by operation, and the procedure of choice seemed to be rigid internal fixation with plate applied in compression and bone graft.

The treatment of frozen shoulder should initially be conservative, with the emphasis on passive stretching of the capsular structures. If the patient's clinical progress stalls or the condition worsens, and his or her life style is disturbed enough, manipulation under gerneral anesthesia is indicated. The Authors practiced the passive manipulation under the general anesthesia on 7 patients of frozen shoulder, who had been treated at the Department of Orthopaedic Surgery, Yonsei University, Wonju College of Medicine, from March 1988 to April 1989. The results obtained were as follows:l. All seven patients achieved nearly full range of motion with minimal or no pain. 2. After 3 months of follow-up, all seven patients showed neither signs of readhesions nor recurrence of pain. 3. There were no complications, such as humerus shaft fracture and dislocation of shoulder.

This is a follow-up study of 88 cases of cementless total hip replacement in 77 patients(59 males and 18 female), using AML, PCA and HGP prostheses, performed at the Department of Orthopaedic Surgery, Yonsei University Wonju College of Medicine, between September 1984 and December 1987. The follow-up period ranged from 18 to 56 months, the average being 34 months. The youngest patient was 21 and the oldest one was 79, the average being 47 years. The results were as follows:1. The average of Harris hip score was 89.7 points(Preop, 55.4 pints) at one year for 77 patients and 91.4 points at two years for 68 patients. 2. Radiographic analysis. a. Radiodense line:10 cases(11.4%) around the acetabular cup. 20 cases(22.7%) around the femoral stem. b. Calcar resorption:4 cases with AML stem(4/30), 2 cases with HGP stem(2/7). c. Subsidence:5 cases in PCA group(5/51).d. Radiological loosening:1 cases in PCA stem(1/51). 3. Intraoperative complications a. Femur neck fracture:15 cases(17%);5 cases in PCA group(5/51), 8 cases in AML group (8/31), and 2 cases in HGP group(2/7). b. Lateral collateral ligament tear:One case in PCA prosthesis(1/51). 4. Postoperative complications a. Prosthetic joint dislocation occured in 3 cases:1 case, closed reduction after tight adductor release:2 cases, cup reinsertion due to poor cup position. 5. Heterotopic ossification developed in 5 cases(5.7%) without significant loss of ROM. 6. Postoperative infection developed in 2 cases(2.3%):One superficial and the other deep. All were treated successfully with systemic antibiotics after irrigation and debridement.

The titanium alloy Ti-6A1-4V is widely used for joint implantation. In spite of its favorable characteristics, titanium alloy can be particularly susceptible to wear, thus generating metallic debris that can lead to aseptic loosening of the implant. We report a case of osteolysis by metal debris after cementless total hip arthroplasty.

The results of treatment of fracture of the femoral shaft with interlocking nailing were evaluated to determine the clinical usefulness. Eighty-two femoral fractures that had been treated by interloking nailing between October 1988 and June 1993 and had been followed for more than one year were included in this study. Fifty-one cases were fresh closed fracture and twenty-four, fresh open fracture. Five cases were delayed union and two were non-union. Closed intramedullary nailing was used in seventy-five cases and open intramedullary nailing in seven cases. The results were as follows; 1.According to Winquist-Hansen classification, 30 cases were type I, 16 type II, 13 type III, 14 type IV, and 9 type V 2. Static and dynamic interlocking nailing were done in 67 and 15 cases respectively. 3. The mean fracture healing period was 17 weeks with a range of 9 to 52 weeks. 4. Intraoperative complications were new fracture near the original fracture site(7 cases), femur neck fracture(l case), pudendal nerve neuropraxia(1 case). Postoperative compliction were delayed union(13 cases), limb shorteniln(4 cases), nonunion(3 cases), infection(3 cases), disal screw brokening(3 cases), nail breakage(l case), proximal screw brodening(1 case) and 12 valgus angulation(l case).

PURPOSE: The study of the causative factors, surgical approachs and the clinical course of symptoms related to sciatic nerve injury after THR. MATERIAL AND METHODS: A retrospective review of 6 patients with sciatic nerve injury in 669 hips total hip arthroplasty during the period from Jan., 1986 to Dec., 1994. Each patient's record was reviewed with respect to age, sex, possible etiology, clinical course, surgical approach, treatment, and clinical condition at follow-up examination. RESULTS: ➀ The increased prevalence of nerve palsy was seen in revision surgeries(4 cases, 3.2%) compared to primary arthroplasty(2 cases, 0.4%) ➁ There was 2 cases(0.8%) of sciatic nerve injury in direct lateral approach and posterior approach, 4 cases(1%) ➂ Possible mechanisms of nerve injury included excessive soft tissue traction(3 cases), electrical thermal injury(1 case), Trochanteric fracture during femoral stem removal(1 case), and overlengthening of femur(1 case). ➃ The isolated peroneal division of the sciatic nerve was injured in 5 cases, and the both peroneal and tibial divisions were injured in one case. ➄ At a following period of 5 month, recovery of neurologic function was complete in con case, and two years follow up, 4 cases had a enough recovery of neurologic function(modified Sunderland scale 1,2). However, remained one case had a persistent severe weakness & dysesthesia at even 3 years follow-up. The prognosis for neurological recovery was related the degrees to which the nerve was damaged.

From Jan. 1987 to May 1994, we carried out cementless total hip arthroplasties using hydroxyapatite-coated Omnifit system, and among these, 63 cases in 49 patients were followed up more than 24 months. The average Harris Hip Score was 46.3 points preoperatively, 95.4 points at POD 1 year and 96.2 points at POD 2 years. Two patients (3%) complained thigh pain at POD 2 years. On the radiologic findings, endosteal bone formation was noted in 34 cases (53,9 %), radiolucent lines were seen at the non-coating region of distal stem in 41 cases (65.3%), which were less than 2mm and not progressive. Cortical hypertrophy was noted in 5 cases (8.4%), and calcar atrophy was observed in 31 cases (49 %).
