The authors treated twenty cases out of 62 scoliosis patients with Milwaukee brace from January 1968 to September 1972 at Department of Orthopedic Surgery, Seoul National University Hospital. The average age were 10.2 years old ranging from 4 to 15 years. Eleven cases were idiopathic, four were paralytic and five were cogenital. The average curvature before the Milwaukee brace application was 44.4 degrees, ranging from 21 to 67 degrees. The average follow up was 15.4 months with average correction of 11.1 degrees, correction rate 19.2 percent. Mild curvature recognized early could be treated successfully by the Milwaukee brace, and also severe curvature of growing period could be not only corrected, but make it more easy for the operative treatment later. Close cooperation with patients and parent are essential for successful trestmant with Milwaukee brace.

Harrington instrumentation with posterior spinal fusion were caried out on 9 patients among 62 scoliotic patients at Department of Orthopedic Surgery, Seoul National University Hospital from January 1968 to September 1972. The youngest patient was 13 years old and the oldest was 17 Six cases were idiopathic and three cases were paralytic type. Preoperative localizer cast was applied and posterior window was made through which snrgery was performed. Harrington inatrumentation was applied in all cases with meticulous posterior fusion and massive autogenous iliac bone graft in Goldstein method. Postoperative immobilization in localizer cast was continued between 25 to 34 weeks, in average of 29.5 weeks. Average preoperative scoliotic curvature was 87.6 degrees ranging from 59 to 118 degrees. Correction obtained by preoperative localizer cast was 37.4 degrees with correction rate of 42.9 percent. Immediate postoperative correction by Harrington instrumentation was from 41 to 69 degrees with average of 50.1 degrees and correction rate of 63.5 percent. The loss of correction in average after two years follow up was 5.2 degrees with rate of 10.2 pecent. Solid bony union was obained in all cases with satifactory result. This treatment is considered excellent method of scoliosis correction and maintainence.

46 knees with injured meniscus diagnosed by the use of history and physical examination as well as by arthrography were meniscectomized from January in 1974 to June in 1978. Statistical analysis of data obtained from the histories, physical examinations and arthrographic studies of 46 knees with a mean follow up 6 months after meniscectomy revealed as follows. 1. Lateral meniscus injuries were higher incidence than medial meniscus. 2. In the posterior horn of the medial meniscus and in the middle third of the lateral meniscus on the injured location were more frequently encountered. 3. To compare the results of twe methods of diagnosis were obtained with 67% accuracy by the use of history and physical examination and with 85% accuracy by arthrography 4. We should be able to diagnosis with 91% armed with a history and physical examination and an arthrogram. 5. As being the excellent results after meniscectomy were classified with 78%.

The giant cell tumor is a primary. neoplasm of bone characterized histollogically by a vascularized network of plumpish or ovoid stromal cells heavily interposed with multinucleated giant cells. The majority of cases occur in patients between 20 and 40 years old and in the long tubular bones, particuarly in proximity to the epiphysis. A rare case of giant cell tumor involving the patella was recently experienced by authors. Case summary with brief review of reference is presented.

One of the most difficult problems confronting the orthopedic surgeon today is what to do when faced with a large defect in a peripheral nerve. Recent advances in engineering and neurophysiology have improved our technical ability to understand the consequences of severing a nerve. We have treated a large traumatic ulnar nerve defect with microsurgical nerve graft technique. In a follow-up study of twehre monthes post surgery, the results were satisfactory.

We assessed the accuracy of clinical evaluation, arthrography, and arthroscopy in the diagnosis of meniscal lesions in twenty-nine knees in which arthrotomy and menisectomy were performed after evaluation by these three methods, At surgery, thirty menisci of twenty-nine knees were removed, of which twenty-eight were abnormal and two were normal. In these thirty menisci, a correct diagnosis was made clinically eighteen times, arthrographically twenty times, and arthroscopically twenty-seven times. Posterior horn tears of medial meniscus and discoid lateral meniscus were well visualized but lateral meniscal tears were poorly visualized on arthrogram. The errors of arthroscopy occurred in two tears confined to outer one half of medial menscal posterior horn, and in a normal meniscus as false positive. Based on this study, it was concluded that both the arthrography and arthroscopy are valuable techniques for the diagnosis of meniscal lesions, and that we can expect correct diagnosis of all the meniscal lesions by the use of complementary roles of the two and by the experiences.

Amputation through the epiphyseal plate is very rare. Authors experienced only one case of ankle amputation through the epiphyseal plate in one huadred seventeen replantation cases during last seven years. It can make severe growth disturbance after replantation especially if the bone shortening is carried out at epiphyseal plate. Authors have developed new idea to make boae shortening during replantation with preservation of the epiphyseal plate in amputation through the epiphyseal plate in three years old female. It is, so called, double osteotomy shortening. Bone shortening is performed at 5cm above amputated epipyaeal plate to avoid further damage in epiphyseal plate, and a bone segment 3cm in length is resected,by double osteotomy shortening technique. After then, bone reduction and internal fixation is followed. With above technique, authors succeeded in replantation without further damage in epiphysis. In three years and ten months follow-up, bony growth in replanted tibia shows normal pattern, and epiphyseal plate in replanted site is working and remained open. The patient can walk without pain, and motor-sensory function have almost completely recoverered.

Bornstein and plate (1911) and Bassoe (1913), followed by many European and American, described the radiographic appearance of avascular necrosis of the bone in compressed air worker. Divers bone lesions was described for the first time by Grutzmacher in 1941. There is not any report of information on the caisson disease and divers bone lesions in this country. Inview of these considerations, during the period from March to June 1981, 124 traditional civilian divers and 132 Naval divers, were observed in eight Korean coastal cities (In-cheon, Sam-chun-po, Sin-hae, Pu-san, Ul-san, Ku-ryung-po, joo-moon-jin and Sok-cho). For each divers, a record was made of his medical history, diving experiences and frequencies of bends attacks. The clinical examination included blood pressure, body weight, a chest radiograph and routine checks of the shoulders, hips and knees, but an X-ray examination extended to the spines, ankles, elbows when symptoms existed. The results were as follow: l. Out of 256 divers, 113 (44.2%) had bone lesions, seventy-five traditional divers (60.5%) had bone lesions out of 125 divers, but naval divers, only thirty eight (28.8%) of 132 had such lesions. 2. Divers bone lesion incidence is increased with diving experience especially over 10 years. 3. The most frequent bone lesions occured in the upper end of the humerus, the upper end of the femur, the lower end of the femur and proximal tibia. 4. The most frequent divers bone lesions in X-ray was dense areas (Bl). 5. There was a high incidence (93.1%) in man with a history of the bends and significantly relate between the sites of the bends and those of the lesions. 6. Divers bone lesions incidence was increased with the length of diving experiences, diving depth, diving time, ages and with bends experiences.

A case of intraneural ganglion of the peroneal nerve in an eleven year old boy is reported. The cystic ganglion, 5.5cm×2.0×1.0cm, which was located at the region of the bifurcation of the peroneal nerve without communication of any joint or bursa, was excised, The ganglion was recurred at 6 weeks after the first excision.

A case of very rare synovial hemangioma of the right knee joint is presented. The duration of disease is for fifteen years. A hemangioma about 6X7X1cm in dimension has been found to be originated from lateral capsular synovium just above lateral meniscus and just anterior to lateral collateral ligament. The joint space was occupied with pedunculated mass. The complete excision could be done. The end result is good.
