Many different methods have tried for the treatment of fractures of the calcaneus in order to search for better results. But there was no general agreement on the treatment of the fracture of the calcaneus, especially involving the subtalar joint. Thirteen displaced intra-articular fractures of the calcaneus(in eleven patients) were treated by open reduction and internal fixation with a plate and screws, or Steinmann pins using a lateral and when needed, a medial approach, followed by early motion. From Feb. 1985 to June 1987, 13 feet in 11 patients of calcaneal fractures involving the subtalar joint were treated by open reduction and internal fixation at the Dept. of Orthopedic Surg., Chonbuk National University Hospital and the results were ss follows : l. Of 11 patients, 9 patients were male and 2 were femsle. 2. The main cause of frscture of calcaneus wss a fall from a height in 81.8% of cases. The spine fractures were associsted in 3 patients. 3. Of these displaced intra-articular frsctures, 3 fractures were tongue type and 9 fractures were joint depression type by Essex-Lopresti classificstion. 4. The tongue type fractures were treated with Steinmann pin and joint depression type fractures were treated with plate and screws. Anatomic reduction was obtained by open reduction snd internal fixation. 5. The average Bohler's angle was 8.1 before reduction and the aversge bohler's angle was 22.1 after open reduction. So, Bohler's angle was 14 increased. 6. After sverage seventy-two months follow-up, the assessment of result by Salama was satisfied in 76.9%-excellent in four(30.8%), good in six(46.1%)-and unsatisfied in 23.1%-fair in two(15.4%), poor in one(17.7%). 7. The surgical approach was used usually lateral approach and, when needed, a medial approach, followed by early motion. 8. The most common complication after treatment was pain on the heel snd subtalar joint.

Forty-six patients (fifty hips) underwent revisions of a total hip arthroplasty that had failed but was not associated with infection, Three of these patients had a third revision. The mean length of follow-up was approximately two years. Thirty patients reported that their condition was improved. On final roentgenographic examination showed, two loosening of the acetabular components and five of the femoral components in which there was one sympto matic loosening (moderate severe pain and probable roentgengraphic loosening) noted. The extralong stems are not necessary in all revision cases, cortical defects at the tip of standard stem obviously should require bypass the stress riser with a longer stem. If the stability can be achieved with host bone, Revision may be carried out with a relatively short stem. Significant postoperative complications as subsidence and progressive loosening were noted in seven out of the forty-six patients. We consider that extensive porocoated cementless stem or standard flute stem seem to be a better outcome in revision arthroplasty.

The authors experienced a case of gastroduodenojejunal trichobezoar detected by ultrasongraphic examination. We thought that tricholbezoar had relatively specific ultrasonographic findings such as a broad hyperechogenic superficial bandlike rim with a complete posteior sonic shadowing and multiple linear echogenic strands on its surface representing hairs, which were better seen after water ingestion. So we were able to get the correct diagnosis of trichobezoar prior to conventional barium studies in a patient who could not be suspected suspected clinically.

Late aseptic loosening of the acetabular component following total hip arthroplasty become increasing frequently after about 10 years and has become a more severe problem both in frequency and severity than femoral component loosening. The complexity of acetabular revision depends largely on the reconstruction required to restore normal anatomy due to acetabular bone loss. The clinical and radiologic results of acetabular revision using a porocoated acetabular component fixed to the pelvis with screws were studied in 36 patients (40 hips) who had moderate or severe acetabular loss. Acetabular revision in patients whose bone stock had already been destroyed provied more formidable problems at revision surgery. The mean Harris hip score was improved 46 to 84. Bone graft union was achieved by 7.4 months and incorporated by 16 months. The graft bone resorption was noted minor degree lateral to the cup. Of 40 cases, 2 cases required re-revision of acetabular cup for identifiable failure of fixation and one was showed probable loosening. The results of the present study suggest that revision of the acetabulum with use of a hemispherical cementless component stabilized with multiple screws and morselized bone grafts filling bone defects appears to be successful in restoring bone stock and providing a stable, pain-free reconstruction.

Patients with severe acetabular bony deficiency in total hip revision arthroplasties need the use of autogenous or allogenic bone grafts. The Authors performed 28 cases of total hip revision arthroplasties between June 1991 and January 1995 with femoral head allograft for acetabular bony deficiencies and evaluated the clinical and radiological results according to AAOS classification. The clinical result was evaluated by D'Aubigne and Postel score. The mean score was improved from 3.9 points to 5.1 points at follow-up. In radiological evaluation, osseous union of graft was achieved within 12 month and rerevision were performed in two cases (92.8% survival rates) but radiological radiolucent line in at least one zone was seen in five hips in two year follow up. In conclusion, the results of hemispherical microporocoat cup with allogenic bone in segmental or cavitary defect using with acetabular reinforcement ring in combined deficiency were encouraging to date. Success rate of allograft reconsruction of the acetabulum results from a variety of acetabular defect. In our studies, only 40% showed stable bony fixation over short period.

Despite the continually improving results of total knee arthroplasty, infection remains the most debilitating complication. The treatments of infected total knee arthroplasty were variable, but initially we removed infected implants and inserted antibiotic containing cemented spacer. Postoperatively, patients were mobilized in a 30 knee flexion state and treated with parenteral antibiotics. After control of infection was clinically and radiologically determined, we inserted PCL substitute total knee prosthesis. Five days postoperatively, patient began touch down standing exercise. We observed two cases in whom infected total knee arthroplasty had been salvaged successfully with two-stage implantation using cement spacers containing antibiotics.

Displaced acetabular fractures have given rise to difficulty to the management, It has been unique diagnostic and operative challanges for the surgeon. We made a retrospective study of hip arthroplasty in fourteen patients who had a history of previous acetabular fracture. The most of patients was sutfered from traumatic osteoarthritis, We performed two bipolar hemiarthroplasty, eleven non-cement cup and one case Charnley cup replacement were done. The purpose of this stady was to determine the outcome long-term cup. The clinical results showed that pain was most improved at foliow-up, but the incidence of radiographic loosening and revisions were higher 42.8% within 10 years. We conclude that a history of prior acetahular fracture has a significant adverse impact on the long term out come of acetabular cup in total hip arthroplasty.
