Extraskeletal Neoplasm Resembling Ewings Sarcoma was firstly reported with comprehensive review of 39 cases by L. Angervall and F.M. Enzinger in 1975. The tumors chiefly affected young adults and most commonly involved the soft tissue of lower extremity. Microscopically, they were consisted of solidly packed small, round or ovoid cells arranged in sheets or lobules, which were indistinguishable from those of the Ewings sarcoma of bone. The authors recently experienced a soft tissue sarcoma occurring in deltoid area of young male patient, which was diagnosed extraskeletal neoplasm resembling Ewings sarcoma. The case review is presented.

The goals of hip arthroplasty have been to eliminate pain, decrease deformity, increase morbility and obtain stabiIity. Currently total hip replacement is the best avaliable procedure to accomplish these goals. A prospective study of total hip arthroplasty was begun at the orthopedic dept of Kyung Hee Medical College in 1974. Between May, 1974 and June, 1977. 69 total hip replacements of the Charnley type, the Trapesoidal-28 type and the Muller type were peformed by the authors. Of the 60 Patients involved in this study, 9 had bilateral operations. The Charnley type Prosthetic device was used in 56 cases, the Trapesoidal-28 type in 7 cases and the Muller type in 6 cases. Complications included wire breakage, dislocation, loosening, femur shaft perforation, nonunion of greater-trochanter, acetabular protrusion, transient femoral nerve palsy, femur shaft fracture, infection, socket lateralization, ectopic bone formation and death. In 59 patients of the 60 patients, 53 patients felt that they were definitely improved, 5 patients felt their condition was unchanged and 1 patient felt her condition was worse.

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.

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%.

Two cases of synovial hemangioma have been experienced at the Department of Orthopedic surgery, Seoul National University Hospital. In the first case, synovial hemangioma about 1.5cm in diameter was found to be attached to the anterior aspect of the medial condyle of the left femur, which was excised completely with good follow-up result. In another case, cavernous hemangioma was observed diffusely invading tendon sheaths, lower one third of the tibia and also synovium of the ankle joint. Because of diffuse involvement, complete removal was not possible. After partial removal, a total 800 r Roentgen therapy was taken.

Congenital Hyperextension of the Knee is a extremly rare deformity, in which the tibia is displaced anteriorly in relation to the femur. It is usually classified into three subtypes according to severity of the status: genu recurvatum, subluxation and dislocation. (Curtis and Fisher) We experienced a genu recurvatum type of congenital hyperextension of the knee in June, 1976.

The previous reports about Supracondylar-Condylar Fracture of the femur which extends to articular surfaces revealed poor results in general, regardless of the methods of treatment. But those results are thought to be much alleviated if they are treated according to the principles of ASIF. Fifteen cases of Supracondylar-condylar fractures of the femur from 13 patients were treated by open reduction and rigid internal fixation during last 3 years at Department of Orthopedic Surgery, Early mobilization of knee joint was permissible in most of the cases without loss of fixation or other complications during convalescence Subsequently, greatifying results were obtained as observed in varying period of follow up days.

A cases is reported of congenital atlanto-occipital fusion in a 12-years-old girl. The lesion was treated by occipito-cervical arthrodesis by iliac bone grafting with wiring. The congenital atlanto-occipital fusion has not progressed in this 2 years of observation. This is presented with a review of literature.

Chondroblastoma is a rare primary bone tumor, The radiologic findings are so similar as giant cell tumor, osteolytic osteogenic sarcoma, enchondroma, bone tuberculosis, etc, but the treatment and prognosis are quite different, the differential diagnosis is mandatory. We experienced unusual huge giant chondroblastoma (10X7X5cm in size) occured in distal femur.

Both clinical and experimental evidence suggest that immunological mechanisms are involved in the pathogenesis of endogenous uveitis. We have analyzed the percentages of T cell, B cell, T cell subpopulations(OKT4, OKT8) and OKT4/OKT8 a in seventeen patients diagnosed clinically as uveitis. The results were as follows; 1. The percentages of T cell and B cell in peripheral blood were 53.0% and 21.1% respectively. 2. The percentages of OKT4 and OKT8 and OKT4/OKT8 were 49.4%, 29.0% and 2.0 respectively, and those were in normal ranges.
