Chronic complication of diving and working in compressed air is dysbaric osteonecrosis. Dysbaric osteonecrosis could be diagnosed by simple bone x-ray, in the case of exposure history to dysbaric atmosphere. The case is 44 years old man who worked as a shell fish diver for 20 years. He was exposed dysbaric atmosphere during diving. He had bone necrosis in both femur head, both distal femur and proximal tibia. He had multiple attacks of decompression sickness. Other causes of bone necrosis are ruled out. We conclude that diver's bone necrosis is dysbaric osteonecrosis.

Thirty nine cases (38 patient) of acetabular fracture and fracture-dislocation were treated in our hospital during the period 1973 to 1977. The short summary of the observation were as follows; 1. Among 39 cases (24 were male and 15 female), the most common cause of acetabular fracture and fracture-dislocation was traffic accident. 2. The acetabular fractures and fracture-dislocations were treated by conservative measures in 25 cases and by open reduction in 14 cases. The results were as follows; excellent in 12(30%), good in 19(48%), fair in 5 (15%) and poor in 3 cases (7%). 3. Among 3 cases of poor results, secondary traumatic arthritis and limitation of motion were observed in two cases and aseptic necrosis of the femoral head, in one case. 4. The result of conservative treatment was satisfactory if the stability of the hip joint and the congruity of the superior weight bearing dome of the acetabulum was well preserved.

We have experienced 52 intra-articular fractures(24 malleolar, 17 patellar, 11 olecranon) treated with tension band wiring from 1972 to 1981 and the results are as followings; 1. The operative technique is relatively simple and easy. 2. In avulsion fractures without communition, anatomical reduction and rigid internal fixation can be achieved. 3. In comminuted fractures, the fragments can be securely fixed with a few additional K-wires including tension band wiring. 4. In avulsion fractures, where the fragment is either too small for screw fixation or too osteoporotic a tension band wiring can be applied with no difficulty. 5. Early joint motion reduces the functional disability and promote the fracture healing.

The bone formation of periarticular connective tissue after head injury and total hip arthroplasty is included in the category of heterotopic ossification. Induction of a new bone formation in the soft tissue is related to various materials such as bone morphogenic protein. The alkaline phosphatase and acid phosphatase act as important factors in the formation and absorption of the bone. The acid phospatase has the important function of acting as the control with specific activity of phosphatase in vivo. Cholecalciferol induces absorption of the calcium in the alimentary tract and bone resorption and increment of bone calcification, whereas disodium etidronate inhibits the deposition and dissolution of calcium salt and formation of heterotopic bone. This paper reports on the relationship of alkaline phosphatase and various phosphoaminoacid phosphatase which affect the cellular differentiation and remodelling in the heterotopic ossification, with the effect of cholecalciferol and disodium etidronate on the heterotopic bone induction in rats. The following results were obtained: 1. The contents of the calcium in the implanted bone matrix increased markedly from two to five weeks. There was no changes in the calcium content by cholecalciferol or in the administration of small doses of disodium etidronate (5mg/kg). However, in the administration of large dose of disodium etidronate (25mg/kg), calcium mobilization was totally suppressed for the whole period of the experiment. 2. The protein content in the implanted bone matrix did not much change for the whole period of the experiment and the administratinn of cholecalciferol or disodium etidronate also had no effect on the protein content. 3. The activities of alkaline phosphatase in the implanted bone matrix peaked at two weeks in control or cholecalciferol group, whereas disodium etidronate admninstration caused the highest activity in the third week. 4. The activity of acid phosphatase in the implanted bone matrix increased in first and third weeks by cholecalciferol treatment. Disoidum etidronate inhibited the activity of the acid phosphatase in the first, fourth & sixth weeks of implantation. 5. The activity of phosphoserine phosphatase increased due to cholecalciferol treatment, but was significantly inhibited by disodium etidronate (25mg/kg) treatment. 6. The activity of phosphothreonine phosphatase in the implanted bone matrix slightly increased due to cholecalciferol treatment, whereas the activity decreased significantly for the whole period of the experiment by disodium etidronate (25mg/kg) treatment. 7. The activity of phosphotyrosine phosphatase in the implanted bone matrix was not change much for the whole period of the experiment and the administration of cholecalciferol or disodium etidronate had no effect on the activity of phosphotyrosine phosphatase. In conclusion, the disodium etidronate (25mg/kg) almost completely inhibited the molilization of calcium and the activities of acid phosphatase, phosphoserine and phosphothreonine phosphatases. Therefore, it can be suggested that the above phosphatases are closely related to the action mechanism of disodium etidronate.

Granular cell tumor is one of the rare tumorous condition. At present there are estimated 600 reported examples of the tumor in the medical literature. Malignant granular cell tumor is a well established but extremely rare entity that is found in appr- oximately 2 % of all granular cell tumor. Diagnosis should be restricted to neoplasms that are similar in their histological appearance to benign granular cell tumors but can be seperated on the basis of cellular pleomorphism, mitotic activity, and, most importantly, their capacity to produce metastases. The authors had experienced that a 55 years old male patient had two large malignant granular cell tumors at the left thigh and left inguinal area with metastatic lesion.

PURPOSE: To investigate the role of porous polyethylene sheet in preventing the recurrence of ptosis after frontalis sling with Prolene(R) and the safety of porous polyethylene sheet. METHODS: Prolene(R) was placed subcutaneously in the thigh of white rabbits. In one group, Prolene(R) was placed with porous polyethylene sheet (treated group) and in the other group, Prolene(R) was placed without porous polyethylene sheet (control group). Prolene(R) was tightened and the loosening of the skin was evaluated at 1, 2, 4 and 8 weeks postoperatively. At the same time, the occurence of complications such as infection, granuloma formation was observed. Histologic examination was done at 2, 4 and 8 weeks postoperatively. RESULTS: In the treated group, skin loosening was progressed significantly for 2 weeks (p<0.05, Mann-Whitney U test) but thereafter there was no significant progression. In control group, skin loosening was progressed for 8 weeks (p<0.05, Mann-Whitney U test). Skin loosening was more severe in the control group at each follow-up evaluation (p<0.05, Wilcoxon signed ranks test). No complication was observed during the follow-up period of 8 weeks. On histologic examination, inflammatory reaction and fibrosis ere seen around Prolene(R) in the control group and fibrovascular ingrowth into the pores of porous polyethylene sheet was seen in the treated group. CONCLUSIONS: This study shows that porous polyethylene sheet can be safely used to prevent the slippage of Prolene(R) and the use of porous polyethylene sheet will be helpful in preventing the recurrence of ptosis after frontalis sling with Prolene(R).
