The displaced intracapsular hip fracture continues to be difficult to manage. Despite significant advances in the technique of internal fixation, the incidence of non-union and avascular necrosis remain high. As a result, prosthetic replacement has been advocated as a solution to this proplem. But the criteria for the management of these fractures by internal fixation, hemi-arthroplasty, total hip replacement have not been clearly well defined, So, we reviewed the result of 28 internal fixation, 7 hemi-arthroplasty, 16 total hip replacement patients at Wonju Christian Hospital. The results obtained from obove patients in the review of esrly ambulation, early and late orthopedic complications, and hip function by Harris hip scoring were as follows ; 1. The average age of the patients were 64-year in the internal fixation, 72-yesr in the hemi-arthroplasty and 70-year in the initial total hip replacement. 2. The most common cause of injury was slip down and the most common type was the fracture of the base of femoral neck. 3. Among the internal fixstion group, the only 11 cases coulddo crutch walking within 2 weeks. But 5 cases(71%) in the hemi-arthroplasty and 11 case(74%) of the of the total hip replacement could do crutch walking within 2 weeks. 4. There was no specific differences in the early post operative complications between three groups. Avascular necrosis of the femoral head and non-union still exist in the internal fixation group and acetabular erosion and protrusion of metallic head occurs frequently in hemi-arthroplasty group. The late complication became increasingly higher in the internal fixation and hemi-arthroplasty group than the total hip replacement group. 5. The measured hip function at the final follow-up showed good end results(57% in the internal fixation, 71% in the hemi-arthroplasty and 81% in the total hip replacement).

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 %).

We conducted a retrospective study of 104 patients to examine the efficacy of two methods of urinary bladder management after total hip arthroplasty under spinal anesthesia. Patients who had total hip replacement was randomly assigned either to Group I, in which indwelling catheters were placed during the operation and removed the next morning, or Group II, in which urinary retention was managed by intermittent catheterization as needed. After the removal of the indwelling catheter, the patients in Group I had a lower incidence of urinary retention than those in Group II. Bladder distention(volume above 700ml) was more common in Group II and was associated with an increased need for subsequent long-term catheterization. There was no significant difference between the groups in the rates of urinary tract infection. We conclude that the short-term use of an indwelling catheter after extended surgery, such as joint replacement, reduces the incidence of urinary retention and bladder overdistention, without increasing the rate of urinary tract infection.

This is a follow up study on consecutive series 50 patients of total hip arthroplasty to assess for transient leg-length inequality. The authors report a clinical experience of 50 patients who have been pelvis tilt before total hip replacement. Retrospectively reviewed for the presence of pelvic obliquity preoperative and at the 1, 3 and 6 months follow-up visits. The results were as follows. Fourty-eight patients(96%) with functional leg length inequality related pelvic obliquity were improved within 6months postoperative follow up period after total hip arthroplasty. Two patients(4%) had persistent functional leg length inequality that affected factors-old age, female and soft tissue tightness due to pelvic obliquity. We believe that in most of these patients, the transient functional leg length inequality has a self-limited course, whereas in a small number, the profoud sense of inequality remains.

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).
