A case of pathological hip dislocation in a child, aged 2 years 6 months, who had surgical treatment, is reported. The boy has history of osteomyelitis of right ilium at age of 10 month, which ended up with the right hip dislocation. Postoperatively cephalocotyloid relation of the right hip was very well reestablished during five years of postoperative observation. Through this case, it is reconfirmed that a child hip has a natural remodelling power even in case of hip joint destruction.

According to literatures, the different types of fractures can occur as a result of arm wrestling ; Spiral fracture of the humeral shaft associating often with a bntterfly fragment, fracture of medial epicondyle of the humerus, and the marginal radial head fracture with anterior dislocation. The last type is very rarely reported. In addition to the fracture occurrence, other injuries such as muscular strain of the arm, and sprain or luxation of the shoulder, elbow and wrist joints can be taken place. However, it is thought that the most of those injuries by arm wrestling have been treated simply by general practioners unreported. The arouse the attention of the jury of the game, wrestlers and the surgenons, the cases of bony injuries sustained during the arm-wrestling are reported. Thirteen patients were treated by us since 1977. Among them, five cases had fractures of the humeral shaft, and eight cases had fractures of medial epicondyle of the humerus. Among the five shaft fractures, three were treated by conservatively, and two by operatively. Among 8 avulsion fractures of the medial epicondyle only two were treated conservatively, and 6 operatively. One patient sustained the medial epicondylar avulsion fracture twice for which K-wire fixation treatment was done. The results of treatment were all satisfactory. However, because of the possibility of wrestlers sustaining such injuries. Arm wrestling should not be considered a totally benign sport.

Voluntary habitual dislocation of the hip is very rarely reported in children, and only 13 cases have been reported in the literature. We add a new case in a 5 year old boy. The boy did not have previous history of trauma, skeletal and/or soft tissue anomalies, nor known connective disease. He was treated by intertrochanteric varusinward rotation osteotomy of the affected hip on February 25, 1985 and was followed until January 11, 1993. Postoperative convalescence was uneventfully successful, and the hip developed well without any obvious dysplasia at the latest follow-up.

Authors presented the experience of Ender nail treatment for the humeral shaft fractures in 24 patients. The results of treatment in all were satisfactory, though there were four cases of delayed union. Bridging callus was formed at 8.2 weeks on an average. The average clinical union time was 14 weeks. No complications developed during nailing procedure. A case of radial nerve palsy after fracture recovered spontaneously. Longer nails which hit the end of medullary canal of distal fragment distracted the fracture gap, and resulted in delayed union in 4 cases. Therefore, it is recommended to use the proper size of nail to avoid the distraction effect of the inserted nail, and to use two nails at minimum for better fixation. However, when intramedullary Ender nailing is properly done, single nailing also can give consistently good anatomic and functional results.

Authors presented the gratifying result of treatment of chronic osteomyelitis with overlying skin defect and/or poor skin condition, which developed the wide skin necrosis after saucerization and resulted the second skin graft necessary. Five cases were treated by primary extensive saucerization of tibia which left a cavity with bleeding walls. The exposed bony surface with bleeding walls was covered by delayed free skin graft when the good granulation covered the bony surface. Through this experience, delayed free skin graft is justified the best procedure in these cases to cover the post-surgical raw bone surface and to have primary healing of the bone infection. A method of hemicylindrical pedunculated skin graft to obliterate the deeply excavated surgical bony defect is introduced.

The present study was designed to define the role of prostaglandin in the development and hatching of mouse embryo. The effects of indomethacin, an inhibitor of prostaglandin synthesis, on the development and hatching of morula and blastocyst were examined. In early morula stage, embryos were degenerated significantly at 100 muM and 200 muM indomethacin. However, :he viability of embryos was not influenced by concentration in any other embryonic stages. In all embryonic stages, the hatching was suppressed with concentration dependent manner, but expansion was not suppressed. Particularly, in 84h embryos post hCG injection, the hatching was suppressed significantly compared with post hCG 72h or 96h embryos. When embryos were treated with 100 muM indomethacin for a specific time (12h) in according to the development stage, the hatching was suppressed all groups. These suppressional effect was decreased as embryonic development stage was progressed. However, the expansion was not affected in all treatment group. This study suggests that hatching-related metabolic substances are synthesized from morula stage and intraembryonic signaling mediated prostaglandin was important for development and hatching of mouse embryo.

Fracture of the tibial shaft is one of the most common fracture of the long bones and, due to its frequency and easy accessibility to traumatic insults, it is frequently complicated with malunion, delayed union and nonunion, and osteomyelitis. Recently, closed flexible intramedullary nailing of the fracture of the long bones has gained popularity. And its application to the tibial shaft fracture is reported to meet the object of fracture treatment by providing maintenance of reduction and by allowing early mobilization of the injured leg. There are other advantages such as stimulation of forming external callus by allowing some motion at fracture site, adequate fixation without exposure of the fracture site. Authors carried out retrospective study of the 56 tibial shaft fractures in 54 patients which were fixed with Rush nails (31 tibial fracture in 30 patients) or Ender nails (25 tibial fractures in 24patients). The results were analyzed to compare the effectiveness of these two methods. The results were as follows: 1. Tibial fracture treated with rush nailing united clinically at 15.7 weeks and united radiologically at 21.8 week on an average postoperatively. 2. There was a tendency of earlier healing of fracture of tibial shaft treated with Ender nailing:clinical union and radiological union were obtained at 12.8 weeks and 18.8 weeks on an average, respectively. 3. Ender nailing has advantage such fracture fragment during insertion. 4. Additional insertion of Ender nail as ease of nailing, low incidence of displacement of undisplaced provided greater stability at the fracture and it was attributable to earlier healing of tibial fracture treated with Ender nailing. 5. Rush and Ender nailings failed to maintain reduction of the fracture of proximal tibia shaft. As the advantages of Ender nailing surpass those of Rush nailing, authors have preference of Ender nailing in the treatment of the tibial shaft fracture.
