Unicameral bone cyst is an uncommon tumor-like lesion of the bone, containing distended channels or cavities filled with serous fluid. Four cases of cystic lesion at the upper end of the humerus were revealed to be unicameral bone cyst roentgenographically and microscopically. Two cases were treated with radical curettage followed by homogenous and autogenous bone graft, and one case was treated with radical curettage followed by homogenous bone graft. The other was treated with radical curettage followed by autogenous fibula graft. All cases made uneventful recoveries, and they had no complaints and no evidence of recurrence, A brief summary of literatures is submitted.

Tuberculosis of the vertebral column is a slowly developing disease, characterized by pain, spinal deformity, and occasionally paralysis. The following varieties of vertebral tuberculosis are commonly recognized, such as a central variety, metaphysial tuberculosis (inter-vertebral articular type), an anterior or periosteal variety, appendiceal tuberculosis, and a true tuberculous arthritis. Among these appendiceal tuberculosis is rare. This form of Potts disease may be unilateral or bilateral and may be isolated or present at multiple levels. Disk space changes and deformity are minor features, but large paravertebral abscesses are invariable. Extradural extension may lead to the development of paraplegia. Two cases of destructive lesions at the neural arch of 10th. and 11th. thoracic vertebra were revealed to be appendiceal tuberculosis. All cases treated with antituberculous medication, radical curettage and body jaket casts and made recoveries. Patients had no complaints and no evidence of recurrence. A brief summary of the literature is submitted.

Legg-Calve-Perthes disease is a hip disorder of undetermined etiology, occurring in children and charaterized by necrosis and repair of the proximal femoral epiphysis. Its etiology and treatment continue to command intense interest among orthopaedic surgeons. It is the purpose of this paper to evaluate the result of our experience in the selected patients with Legg-Calve-Parthes disease treated by innominate osteotomy, In this study, six cases of Legg-Calve-Perthes disease treated at Severance Hospital from March 1976 to November 1978 were analysed clinically, and gratifying results were obtained.

The ankle is a complex, weight-bearing joint and has an important role in walking. The injuries to the ankle joint complex include not only injuries that cause disruption of the bony architecture of the ankle joint but often significant ligamentous and soft tissue components. The literature on ankle fractures have divergence of opinion on treatment. However, the method used to obtain a good end result of treatment is a matter of differing opinion. One hundred and seventy six patients with one hundred and eighty cases of ankle fractures treated at Severance Hospital, Yonsei University College of Medicine from Jan. 1971 to Dec. 1980 were analized in clinical and radiological aspect. The results obtained from this study were as followings: 1. Among the 176 patients, male was 126 patients and female 50 patients (M:F=2.5:1). The average age was 29. 2. Of the 180 cases, the main cause of fractures was traffic accident, 74 cases (41.1%) and the other causes were falling from a height (16.1%), slipping down (15.0%) and sports injuries (12.8%) in order. 3. The fractures were almost closed fractures (84.4%). 4. According to the classification of Lague-Mansen, the pronation-external rotation type (40.6%) was the commonest type. 5. One hundred and twelve cases (62.2%) were treated by open reduction and 68 cases (37.8%) by closed reduction. 6. The average period of the cast immoblization after the open reduction was 8 weeks but the closed reduction was 10 weeks. 7. According to clinical and radioiogical assessment of the result of the treatment, the open reduction was better than closed reduction. 8. The fibular fracture involving lateral malleolus and the diastasis of the distal tibiofibular syndesmosis were very important in ankle stability and were treated by internal fixation for accurate anatomical reduction.

Supracondylar fractures of the humerus is the most common elbow fractures in children. Many papers has been published about the treatment of the supracondylar fractures of the humerus in children and prevention of both Volkmann's ischemic contractures and nerve injuries associated with these fractures, however, unfortunately it is still one of the most difficult fractures to manage. After successful reduction, the late complications of loss of elbow motion, the change in carrying angle, myositis ossificans, and progressive ulnar nerve palsy still lie ahead. For the period of 5 years from January 1975 to December 1979, 110 patients who had been treated for supracondylar fractures of the humerus at Severance Hospital, Yonsei University Coilege of Medicine were studied and analyzed retrospectively and the results are summerized as follows: 1. The age of the patients varied from 1 to 26 years, the majority (80.0%) being between 4 to 11 years and the fractures were on the left side in 71.8% and males comprized 75.5%. 2. The extension type comprized 94.5%. 3. Most common complications were cubitus varus deformities. 4. Percutaneous pinning and open reduction and internal fixation elicited rare cubitus varus diformities. 5. Limitation of motion was most frequent camplication after open reduction and internal fixation. 6. All cases which showed cubitus varus deformities were initially medially displaced fractures. 7. Four median nerve injuries were associated with posterolateral displacement and one radial nerve injury was associated with posteromedial displacement. 8. Finally, with prompt and adequate treatment, there were no Volkmanns ischemic contractures seen in this study.

Early detection of skeletal disorders was very important role in establishing therapeutic modality and prevention of complications. Since Tc-99m-phosphates derivatives used in bone scan agent, remarkable improvement was noted in effectiveness, cost, radiation hazard to patient and image quality than previously used agents such as strontium or fluoride. Bone scan with Tc-99m-MDP was done in 155 cases for early diagnosis of skeletal disorders at Severance Hospital, College of Medicine, Yonsei University from August, 1980 to May, 1982 were analyzed both clinically and radiologically, and the following results were obtained. l. Among 19 cases of avascular necrosis, positive cases were 17 (89.5%) in bone scan and 6(31.6%) in X-ray. Positive pattern could be classified into 3 types and the radionuclide uptake in the femoral head was decreased in 3 cases which was negative in X-ray and duration of their symptoms was within 4 months. 2. Fifteen among 17 hip fractures or dislocations were positive in bone scan. In 12 (80.0%) among 15 cases, complications were revealed and positive cases in X-ray were 7(58.3%), which were all positive in bone scan. 3. In 20 bone scans for early diagnosis of acute osteomyelitis, positive in bone scan were 17 and 14 (82.4%) of 17 cases were finally diagnosed as acute osteomyelitis. Among 15 cases diagnosed as acute osteomyelitis, positive in X-ray were 8(53.3%) and sensitivity of acute osteomyelitis in bone scan was 93.3%. 4. In 25 cases of the suspected infection of the joint, 15 were positive in bone scan and among them, cases diagnosed as pyogenic arthritis were 12 (80.0%) and positive in X-ray were 2 (16.7%). Only one of 10 cases of transient synovitis of the hip joint was positive in bone scan. 5. In rheumatoid arthritis, 13 of 15 cases were positive in bone scan and 10 among them were revealed the diffuse uptake of the radionuclide in the joint. In degenerative arthritis, 7 of 8 cases were positive in bone scan and they were revealed the focal uptake of the radionuclide in the same site where the bone was changed in x-ray. 6. Among 28 cases showed spine fracture in X-ray after trauma, 15 (53.6%) were positive in bone scan. In spine fracture, it was difficult to differentiate fresh fracture from old fracture with bone scan. The positive duration of bone scen in fracture of weight bearing bone was longer than in spine fracture. Rib fracture which was not found in X-ray could be diagnosed with bone scan.

Congenital muscular torticollis is a distinct entity, in which the primary pathologic picture is limited to the sternocleidomastoid muscle. Associated deformities of the face, head and cervical spine are secondary in character, resulting from an abnormal position of the head both prior and subsequent to birth. The etiology of congenital muscular torticollis is not clear yet. There are various opinions about adequate age and methods for treatment. From January 1970 to December 1984, 53 cases of congenital muscular torticollis were treated surgically at the Department of Orthopedic Surgery, Severance Hospital. From January 1980 to December 1984, 10S cases of congenita muscular torticollis were treated conservatively at the same hospital. Totally, 161 cases were studied and analyzed retrospectively and the results are summerized as follows: 1. Among the 161 cases, thers were 88 males and 73 females. The lesion was on the left side in 89 cases. 2. There were 85 cases of normal spontaneous vaginal delivery and 58 cases of complicated labor including 34 cases of breech delivery. 3. There were 6 cases associated with other congenital anomalies; one of them was combined with congenital subluxation of the hip joint. 4. Results of conservative physiotherapy were good under 1 year of age and results of surgical correction were good under 6 years of age. 5. The failure of conservative physiotherapy did not influence the results of surgical correction performed later. 6. The results of reoperation, when the initial surgical correction failed, were not as good. 7. Facial asymmetry correction results were especially good under 6 years of age when much growth potential remained. 8. There were no differences in results according to the various kinds of cervical braces although the results were good when the cervical brace was worn over 3 months. 9. On pathologic examination, there was no hemorrhagic reaction. The muscle was atrophied and was replaced by fibrous bands. Therefore, congemtal muscular torticollis is thought to be caused by abnormal intrauterine position rather than by birth trauma, and it is expected to get a good result by treating congenital muscular torticollis as early as possible.

We analyzed 27 cases of Legg-Calve-Perthes disease that were treated by operative methods at the Department of Orthopedic Surgery, Yonsei University College of Medicine from 1975 to 1981. The modalities of treatment were innominate osteotomy in 17 patients; subtrochanteric osteotomy of femur in 4 patients; and adductor-iliopsoas tenotomies in 6 patients. Most of the cases were in Catterall group III or IV diseases with two or more of “head at risk”signs in the preoperative roentgenogram. All but one case were aged more than 7 years at the time of surgery. In all cases clinical and radiological evaluations were performed until the affected femoral head had been fully regenerated. The average period of follow-up was 2 years and 11 months. Final result by Catterall's criteria was good in 15 cases (56%), fair in 7 cases (26%) and poor in only 5 cases (18%). Among 17 cases treated by innominate osteotomy, 13 cases (76%) were in good result and there was no poor result; 15 cases (86%) showed normal containment at the last follow-up x-ray. To compare these end results with those of noncontainment treatment reported by many authors, we were encouraged to proceed our current policy of early definitive containment surgery especially in patients with poor prognostic factors. In cases of estabilshed femoral head deformities that can be confirmed by preoperative arthrography, adductor-iliopsoas tenotomies were useful to restore normal range of motion of hip joint and to prevent further subluxation of the femoral head. The significant prognostic factors at the time of surgery were the patients age; stage of disease; involvement of femoral head; and finally early established irregularities of the femoral head. In every cases of Legg-Calve-Perthes disease these factors should be carefully assessed to make proper decision for the choice of the most effective modality of treatment.

Synovial sarcoma is a very rare malignant tumor which arising from the synovial lining connective tissue, tendon sheaths and bursae. However, there are a few case reports of this tumor arising from the bone. We have experienced 3 cases of the tumor from the bone, i. e. the head of the left fibula, the sacrum and the right ileum, and the distal end of the left femur. Microscopically they showed typical slit like spaces, lined by epitheloid cells or cuboidal cells and one could easily find out spindle, polygonal, or giant cells. The proximal third of the left fibula was excised, and the other case arising from the sacrum & right ilium was treated with radiation therapy. Another case refused hip disarticulation, The effectiveness of the treatment is uncertain.
