Fracture of the scaphoid constitute 60% to 70% of all diagnosed carpal injury. The acute fracture will heal approximately 90% of the time if recognized early and properly immobilized. But nonunion are common since the symtoms do not alert patients to seek early medical treatment and the diagnosis is easily missed. Authors have experienced 19 cases of scaphoid nonunion and accomplished good result in all case by Russe procedure. The results were summerized as follow: 1 The cause of fratures was mainly due to fall down dinjury (36.8%). 2. The most common mechanism of the fracture was fall on the outstretched hand (52.7%). 3. Fractures were shown on the anterior-posterior, lateral and billiards view in all cases. 4. In ten cases, the fractures were found on the waist of scaphoid. 5. The cases of nonunion were probably inadequate intial treatment and delayed diagnosis. 6. The good results were obtained by bone graft according to Russe procedure.

The herniation of intervertebral disc is possibly diagnosed through the myelography, electromyography, discography or computerized tomography. Among them, the myelography is regarded as the popularized method that helps accurate analysis on the location and pattern of the lesion. The authors have studied 363 cases of herniated intervertebral disc with respect to the diagnostic accuracy of myelographic examination from January, 1982 to December, 1985 at the Department of Orthopedic Surgery and Radiology, National Police Hospital. The results were as follows; 1. The most common age group was 21 to 30 years old and ratio of male and female was 9.7: l. 2. The most common site of the lesion was between L4 and L5 vertebra in myelography. 3. Of the 363 cases which underwent the myelography, 305(84.0%) represented positive findings. 4. Myelographic accuracy was coincided with the clinical diagnosis regarding the location of herniation of intervertebebral disc in 262 cases(72.1%).

Reduction in the extremity length of more than three to four centimeters has significant effect on both gait disturbance and aesthetic change. The method of Anderson has been one of the most successful procedures of surgical leg elongation but requires long period of bed rest and immobilization. Also. the lengthening occurs the tibia, although shortening occurs twice as frequently in the femur as in the tibia. Wagner in 1971 reported his experience with the technique that allows correction in both the femur and tibia yet does not require prolonged immobilizaton. This involves a two stage procedure with rigid external fixation and lengthening of 1.5mm per day. The second stage is for osteosynthesis and may be suppleniented by bone graft. We began using the Wagner's technique of leg lengthening at Chonju Presbyterian Medical Center about 18 months age. Two patients are presented with 7 and 9 month follow-ups after femoral lengthening of 5 cm each. Both femurs united well and the leg length discrepancy was corrected. These cases indicate that this method is a good addition to the armamentarium of treating leg length discrepancy. A subsequent review of more cases and their follow-up using this tretment program shall be forthcoming.

The skeleton is a frequent site of bone tumor metastasis. Radiographic examination Is not sufficiently reliable in early detection since an abnormality is unlikely to be observed until more than 50% of the bone material has been lost. Therefore there was much effort to discover radiographic materials for use in scanning. At the present tirne, 99m Tc-labeled diphosphonate is the best available material for bone scanning. We applied whole body scanning with 99m Tc-to 40 patients who had bone tumors (primary or secondary), infection and other cases. The results obtained are as follow: 1. The scan can detect the extensiveness of the tumor better than plain X-ray in the early stage. 2. In metastatic disease, 60% of all patients were positive in the scan and all of there were negative in X-ray. 3. In cases of cancer, definitive treatment planning can be facilitated by the information obtained from whole body scanning. 4. In inflammatory disease, we can differentiate osteomyelltis from cellulitis or pyogenic arthritis in the early stage. 5. In fibrous dysplasia, it was possible to differentiate monostatic from polyostotic disease. 6. In nonunion of bone, scan was positive but X-ray was eouivocal.

Ganglia are ubiquitous but periosteal ganglion is rare. This case is presented showing an unusual radiological picture. The radiological picture with honey combed appearance is striking. Previaus reports have stressed the concavity in the cortex. Histologically the structure is identical to that of soft tissue ganglia.

A simple out-patient's procedure with the use of a simple 17 or 18G hypodermic needle for the percutaneous release of trigger finger is described. The authors are reporting the satisfactory result obtained by means of percutaneous release of tendon sheath without skin incision in 21 trigger fingers of 17 patients treated at the out-patient-basis.

Moving on the femoral srticular surface, the patella is doing a significant role in the patellofemoral mechanism as one of the most important components of the knee. The knowledge of patellar movement would be very helpful to understand the functional mechanism of the knee We studied the distance of patellar movement during the knee motion on the lateral X-ray view of 100 normal adult knees. The results were as follows :1. The average distance of patellar movement from full extension to full flexion of the knee was 8.4cm. 2. Patella moves average 1.7cm(20.2%) form 0° to 30° flexion, 2.6cm(31.0%) from 30° to 60° flexion, 1.7cm(20.2%) from 60° to 90° flexion, 1.3cm(15.5%) from 90° to 120° flexion and l.lcm(13.1%) from 120° to full flexion.

Ulnar lengthening, one of the operative treatment methods for Kienbock's disease, is based on the theory that ulnar minus variance is a significant causative factor of Kienbock's disease. It is considered that this method can promote the revascularization of the devascularizied lunate by reducing the forces concentrated at the wrist joint and that over-all carpal collapse is halted or reversed when the ulnar part of the carpus is supported better. 4 patients with Kienbock's disease treated by ulnar lengthening with iliac bone graft were reviewed after follow-up ranging from12 months to 30months. In all of 4 patients, relief of pain was satisfactory and there was no remarkable complication.

Through the review of 137 cases of ankle fracture treated and followed up in Department of Orthopedic Surgery, National Police Hospital, we got the following results. 1. Slipping was the most frequent cause of the fractures(45.3%). 2. Supination-external rotation type of Lauge-Hansen classification was more common than any other types(67.9%). 3. 94 cases out of 137 cases were treated by open reduction and internal fixation, and remaining 43 cases were treated conservatively. 4. The average duration of cast immobilization was 7.3 weeks for the operatively treated cases and 9.1 weeks for the conservatively treated cases. 5. The result of treatment was good or excellent in 87 cases(92.6%) of operatively treated 94 cases and in 36 cases(83.7%) of conservatively treated 43 cases. 6. We think that the anatomical reduction of the lateral malleolar or distal fibular fracture is necessary for better end results.
