Articular cartilage can be damaged by trauma or by progressive degradation caused by disease. Unfortunately, it has a extremely limited capacity for repair and regeneration. The use of joint prosthesis has revolutionized but remains limited in its use. To know the possibility of clinical application of clinical application of autogenous bone-articular graft in open complicated intraarticular fractures we studied the change of bone-articular cartilage defect in medial femoral condyle of rabbits and viability of autogenous bone-articular graft stored within abdominal wall of rabbits. The results were obtained as follows: 1. There was over 90% viability of subchondral bone after 10 days storage in the adbominal wall but the articular cartilage showed degenerative change about 40% after 5 days passed. 2. The bone-articular defect was replaced by undifferentiated mesenchymal tissue and fibrous tissue, postoperative 6 weeks later. 3. In implanted bone-articular cartilage graft at 3 days, the chondrocyte of basal cell layer in articular cartilage was relatively well preserved but in 7 days, transplanted articular cartilage graft showed almost necrotic chage. Most of subchondral bones were well healed with host bone without regard to duration of implantation.

PURPOSE: We reviewed 5 years worth of experience with peritoneal drainage and dialysis in infants who underwent open heart surgery. The aim of this study was to investigate the effect of peritoneal drainage and peritoneal dialysis on fluid balance and several parameters of intensive care. METHODS: Six(10%) of 60 consecutive infants who underwent open heart surgery required peritoneal dialysis during peritoneal drainage. Simple peritoneal drainage was performed in the remaining 54 infants. The silicone rubber peritoneal dialysis catheter was inserted into the center of abdominal cavity just after operation, and subsequent peritoneal drainage was maintained during intensive care. RESULTS: Mean age of the study group was 0.48+/-0.21 years(M: F=32: 28). Early postoperative mortality amang the infants with congenital heart disease was 1.6%. Total amount of output was 7.0+/-2.28mL/kg/hr, urine output 5.14+/-2.9lmL/kg/hr, pleural fluid 0.80+/-0.5lmL/kg/hr, and peritoneal fluid 1.20+/-0.90mL/kg/hr. The ratio of output to intake(O/I) was 1.06. None of the complications required early termination of peritoneal drainage or peritoneal dialysis. Hemodynamics and pulmonary function were maintained steadily during postoperative intensive care. CONCLUSION: The early institution of peritoneal drainage and peritoneal dialysis in infants with congenital heart disease after cardiac operations not only removes fluid, thus easing fluid restriction, but may also improve cardiopulmonary function.

The ankle joint is a modified complex hinge joint which plays an important role in weight bearing, walking and standing. Injuries about the ankle joint cause destruction of not only bony architecture but often also the ligamentous and soft tissue component. So the goal of the treatment of ankle fracture is restoring normal relations of ankle mortise and regaining a smooth articular surface. The author have reviewed 84 cases of ankle fractures which were treated through the admission in the Orthopedic Department, In Je Medical College Pusan Paik Hospital from June 1979 to August 1986. The average duration of the follow-up was one year. The results obtained from this study were as follows : 1. The most common type was Danis-Weber type C. Nexts were B and A in order. According to the classification of Lauge-Hansen, the most common type was Pronation-external rotstion(39.2%). 2. In Danis-Weber type B and C, satisfactory result was obtained by operative treatment. 3. Danis-Weber's classification was very practical criteria for treatment of the ankle fracture.

Total anomalous pulmonary venous return(connection) is a congenital heart disease. Especially, the reports of the patients with double connections of all pulmonary veins were rare. An infant who underwent operation for total anomalous pulmonary venous return had double drainge of all pulmonary veins to both left vertical vein and anomalous descending vein. This second lesion was not diagnosed preoperatively, but in operative field. Operative treatments were performed by ligation of left vertical vein and central pulmonary vein-to-left atrium anastomosis without ligation of the descending anomalous vein. For these less common variants fo total anomalous pulmonary venous return,a more detailed and precise understanding of morphology can facilitate accurate surgical repair. And also, early detection of the disease is an another issue for a good prognosis.

Development of acetabulum and epiphysis of the femoral head following reduction in seventy-four patients with ninty-one congenitally dislocated hips were assessed radiologically. Acetabular index, CE angle of Wiberg, neck-shaft angle of the femur and overgrowth of the pelvis and femur were measured according to the various treatment. To evaluate results, the method of treatment was divided into four groups; closed reduction, open reduction, open reduction combined with pelvic osteotomy and modified Klisic operation (open reduction, pelvic osteotomy, femoral osteotomy and so on). Each treatment was compared with three subgroups according to ages; first subgroup was belong to patients under one year of age, second from one year to three years, third over three years. This paper agrees to Harris (1976) and Lindstrom (1979) about improvement of acetabular index and CE angle of Wiberg that showed a rapid rate of repair in the first 6 months and thereafter slowly progressed to normal range of degree. Overgrowth of pelvis and femur was also noticed in cases of hips treated pelvic and/or femoral osteotomy, moreover even in cases of open reduction only. The goal of this preliminary investigation may be supposed to propose the idea which method of treatment to the first visiting patient will approach the most satisfactory final result.

Pathologic fracture is a bresk of bony continuity within an abnormal bone. The abnormslity ma be due to systemic skeletal disease, infection, primary benign and malignant tumor, or metastati carcinoms. Among these, metastatic carcinoma to bone is most common cause of pathologic fractur excluding those due to osteoporosis. When considering the msnagement, pathologic fractures due to systemic skeletal disease usually heal with conservative treatment, while others often require operative treatment. We have experienced 20 cases of pathologic fracture in long bones for 8 years from 19 to 1987. The results were as follows ; 1. The average sge was somewhat different according to underlying diseases Malignant tumorous lesion; 53 years Benign tumorous lesion ; 17 years Chronic osteomyelitis, 42 years 2. The most common cause was malignant tumorous lesion, 8 cases(40%). 3. The most frequent site was femur, 17 cases(85%). 4. Surgical treatment was done in 17 cases(85%), and conservative treatment was done in 3 cas(1sw). 5. In 3 cases of pathologic fractures due to metaststic tumor, the pain was markedly relieved and essy nursing care was possible immediately after operation.

Thoracic disc herniation is an uncommon cause of thoracic cord compression. Herniation in this region is of particular importance because of the serious disorders of nervous function which result from anterior compresstion of the spinal cord. Early diagnosis and prompt surgical treatment are imperative because of the progressive and serious neurological deficit which results from delay. Numerous problems remain as to the safest surgical approach to the prolapsed thoracic intervertebral disc. We treated a case of herniated intervertebral disc occuring at Tll–T12 using the anterior approach. The result was favourable.

Pott's paraplegia has been frequently serious complication of tuberculous spondylitis, although antituberculous drugs have improved the prognosis and healing of the disease. There are much controvercy on treatement of Pott's paraplegia, which comprises immobilization with or without anterolateral antituberculous drugs, immobilization and early posterior arthrodesis, anterolatear decompression and radical anterior decompression with anterior spinal fusion. The method of anterior decompression and anterior interbody fusion which was introduced by Hdgson since 1956 has good reults. The author analyzed 27 consecutive cases of Pott's parsplegia operated at orthopedic departement, In Je Paik Hospital from May 1980 to August 1988. The results were as follows, 1. Number of cases in child was nine(33%), both sexes were similar. 2. Regions of spine involved were most common at thoracic spine(62%). Number of affected vertebrae was averaged 3.3 vertebrae. 3. There were nineteen early(70%) and eight late(30%) paraplegia. 4. There were two complete and twenty five incomplete paraplegia. 5. In operative finding, inflammatory products and sequestrated material was extrinsic factor in early in paraplegia. 6. The recovery of the paraplegia occur in twenty cases(74%) 7. The recovery of paraplegia after treatment was far better in type of early onset, type of incomplete paraplegia less than one year duration. 8. The radical anterior decompression and anterior interbody fusion was considered as recommendable method for remove of all pathologic foci, recovery of paraplegia and healing the tuberculosis with stability.
