Chondroma of Soft Tissue: A Case Report / 대한정형외과학회잡지

A case of chondroma of soft tissue of right hand in 23-year old man was reported. The presenting symptom was a slow growing mass, causing mild tenderness. Radiologic examination revealed a well demarked and lobulated calcified mass, was located extraskeletally. Specimen exised from soft tisssue of the hypothenar area of the hand was 5×4×3.5cm sized mass, had gelatinous and gray-whitish appearance. On microscopical examination, the tumor was classified as a chondroma of soft tissue.

Osteochondritis Dissecans of the Knee / 대한정형외과학회잡지

Osteochondritis dissecans is a condition in which part of the articular surface of a joint separates, due to a plane of cleavage through the subchondral bone. It is found most commonly in the knee although other joint can be affected, notably the elbow, ankle and hip. The etiology remains unclear, and treatment still provokes controversy in the orthopedic community. This review is confined to osteochondritis dissecans of the knee and reports the result of different methods of treatment including arthroscopic drilling. The authors experienced 7 cases of osteochondritis dissecans with received treatment at C.A.F.G.H. from May 1982 to November 1984. The results were obtained as follows: 1. Common symptoms and signs were pain, limitation of motion, quadriceps atrophy and weakness. 2. Five of six cases had histories of trauma. 3. The methods of treatment were as follows: Curettage and drilling................................................... 2 Excision ...................................................................... 2 Curettage and bone graft .............................................2 Arthroscopic drilling .................................................... 1

Congenital Pseudarthrosis of the Tibia: 5 Cases Report / 대한정형외과학회잡지

Five cases of congenital pseuduthrosis of the tibia were treated at Department of Orthopedic Surgery, Yonsei Medical Center from September 1971 to February 1982. In four cases, many cafe-au-lait spots were shown on the whole body skin, which are suggestive of neurofibromatosis. The evidence of hereditary factor is elicited on Case 2. Satisfactory bony union occurred in Case 1 & 3 in which the delayed autogenous bone graft was used. Among various methods of treatment of the congenitaeudarthrosis, in this study, the delayed autogenous bone graft and the free vascularized bone graft was recommended.

Cubitus Varus Deformity following Long-term Crutch Walking in Crippled Children (Crutch Elbow) / 대한정형외과학회잡지

Cubitus varus deformity caused usually by malunion in supracondylar fracture or epiphyseal injuries of the elbow joint, but the other causes of cubitus varus deformity have not been reported. 7 cases of cubitus varus deformity were found among the patients in Sam Yook Childrens Rehabilitation Center in Oct. 1981 all of whom used crutches in order to ambulate due to late sequele of poliomyelitis. The results were as follows. l. After long-term crutch walking, cubitus varus deformity and bowing around the proximal forearm were seen among the patients who mis-used the crutches. 2. Gross carrying angle was greater than radiographic carrying angle and it caused by hypertrophy of the extensor muscle group in forearm and bowing around the proximal forearm. 3. Etiologic factors of the cubitus varus deformity were considered to be improper measurement of the crutches, degree of paralysis of lower extremity and duration of the crutch walking, etc. 4. The mechanism of this deformity could be explained biomechanically by the abnormal axial loading onto the elbow following long-term crutch walking. 5. The correct measurement of the crutches and proper flexion of the elbow during crutch walking were stressed.

Clinical Analysis on the Metastatic Bone Tumors / 대한정형외과학회잡지

A total of 200 cases of metastatic bone tumors was treated at the Yonsei Medical Center during the 5 years period from January 1976 to December 1980. The results of clinical radiological and pathologic analysis are as followings. 1. Among 200 cases of metastatic bone tumors, common site of cancer comprised the lung (30.5%), breast (15.0%), uterus (8.5%), stomach (6.4%), thyroid (3.5%), liver (3.5%), kidney (3.5%), nasopharynx (3.0%), and prostate (2.0%). In male, common primary sites of cancer were lung, stomach, kidney, oropharynx in decreasing order of incidence and in female, breast, uterus and lung. 2. In metastatic bone tumors, 75.5% were observed in the age group between 41 and 70 year of age, and average age was 53.1 years. 3. The sex distribution was 107 males (53.1%) and 93 females (46.5%). 4. The bones affected most frequently in this series were as followings; In only 9 cases (4.5%), metastasis to bone distal to the elbows and knees occurred. 5. Clinical features in this series were classified according to various conditions. Bone pain noticed on 163 cases (81.5%), fatigue on 152 cases (76.0%) and weight loss on 128 cases (64.0%). 6. Pathologic fractures occurred on 22 cases (11.0%); among them, 13 cases on the femur, 5 cases on the vertebrae, and 1 case on the acetabulum, humerus, rib and clavicle respectively. 7. Hematologically, serum calcium and phosphorus was noticed within normal limits. Serum alkaline phosphatase was slightly elevated and serum acid phosphatase was elevated in all cases of prostatic carcinoma. Serum albumin/ globuline ratio was slightly reversed (3.4/3.5mg%). 8. Radiologically, 86 cases were osteolytic, 10 cases were osteoblastic and 44 cases were mixed type. False negative on X-ray examination with positive finding of scan with 99mTc-MDP were found in 17 cases (27.4%). 9. All cases was treated by various methods; among this series, radiation and chemotherapy performed in 57 cases, radiation in 49 cases, chemotherapy in 14 cases, hormone therapy in 16 cases and radioisotope therapy in 5 cases. For 22 pathologic fractures, conservative treatment was performed in 9 cases, open reduction and internal fixation in 13 cases, open reduction and internal fixation with acrylic cement in 5 cases.
