12 cases of Thompson's quadricepsplasty for extra-articular ankylosis of the knee joints which we experienced, were evaluated and analyzed. We obtained the following results. 1. Most of our cases had fracture in the middle one third of the femur. 2. Average 62.5 degrees of flexion range was gained by the operation. 3. Among the 2 cases in which extension lag existed before the operation, it has disappeared in one and still remained in the other case after the operation. 4 cases of new extension lags appeared after the operation. Average extension lag after the operation was 13 degrees. 4. Immediate postoperative exercises and adequate physiotherapy are considered to be very important.

For the management of adult dysplastic hips with early degenerative arthritis, we can prevent further progress of secondary degenerative changes of the hip by a Rotational Acetabular Osteotomy, which effectively corrects the preoperatively inadequate acetabular coverage of the femoral head. Biomechanical advantages of this procedure are, l. An adequate coverage of tl; femoral head then enlarges the actual weight-bearing surface area, and so diminishes the resultant force per unit area of the acetabular weight-bearing surface and femoral head. 2. The resultant forces are also diminished by a medial shift of the femoral head. 3. The shearing force is decreased by the reduction of roof obliquity. 4. Because of the rotation of the original articular surface, remodeling the post-operative acetabular articular surface as Chiari operation is not necessary, and so can be performed even on elderly patients.

BCG osteomyelitis occurs in the infants and children as complication of BCG vaccination and its occurrence is very rare. It involves the metaphysis of the long bone and its development is chiefly hematogenous spread and direct inoculation. Radiologic feature shows well demarcated, eccentrically located destruction in the metaphysis of the long bone and soft tissue swelling about the lesion but periosteal reaction was absent initially. We experienced a case of BCG osteomyelitis which occurs in the left proximal humerus in 3 month after BCG vaccination.

Supracondylar fracture of the humerus is the most common fracture of the elbow in children For period of 4 years from Jan. 1980 to Dec. 1983, 54 children with dispaced supracondylar fracture of the humerus were classified by direction of displacement of distal fragment and treated by immediate closed reduction after lateral skeletal traction. 32 cases of these were followed up for more than 6 months. The results were obtained as follows.: 1) The most common incidence (79.6%) was 5 to 12 years of age and male and female ratio was 2.4 : l. The left humerus was involved in 35 cases (64.8%). 2) Of all fracture, extension type was 96.3% and flexion type 3.7%. 3) Under the exact anteroposteier and lateral views, fractures were classified by displaced direction of distal fragment. Immediate closed reduction was done by using thick and strong periosteal hinge after lateral skeletal traction. The more accurate anatomical reduction was obtained by maintenance of reduction state and further correction during lateral skeletal traction, and complications such as VIC, loss of reduction were lessened probably. 4) For follow up study of 32 cases, final result were analized according to Mitchells classification. Excellent results were obtained 23 cases (71.9%) Good results were 8 cases (25.0%) Unsatisfactory result was 1 case (3.1 %) 5) In 2 cases of treatment failure, the brachialis muscle was buttonholed by metaphyseal spike of the proximal fragment. 6) During lateral skeletal traction, superficial infection was developed through pin tract in 4 cases. These were treated by the administration of antibiotics and there were no complication such as osteomyelitis.

The fractures of the supracondylar region of the femur are difficult to manage because of the wide range of potential complications. In the past, conservative treatment was considered superior to internal fixation of the supracondylar fractures of the femur in adults. Recently the new fixation devices and techniques were developed. After then, the accurate anatomical reduction, rigid internal fixation, and early ambulation have more improved results of the treatments than the past. However the management of supracondylar fractures of the femur remains controversial. The following clinical results was shown by analysis of 48 cases of supracondylar fractures of the femur treated in the Department of Orthopedic Surgery, Chosun University Hospital during the past 6 years from Jan. 1979 to Dec. 1984. 1. The ratio between males and females was 3: 1, and the most case was active age. 2. The most common casue of injury was traffic accident(32 cases). 3. A classification of supracondylar fractures was divided according to Schatzker's classification, and the most common type was type II (20 cases). 4. In the methods of treatment, surgical treatment by open reduction and internal fixation was used for 32 cases, the conservative management by using skeletal traction for 16 cases. 5. The satisfactory result of surgical treatment was 60% and conservative treatment was 43.7% respectively. 6. The most common complication was the ankylosis of the knee joint.
