Osteochondritis dissecans occurs most commonly in knee joint and often in elbow, ankle, shoulder, hip than in other joint. In osteochondiritis dissecans, an area of subchondral bone undergoes avascular necrosis and degenerative change ususlly occurs in cartilage overlying it. During the course of disease, unless interrupted by treatment or spontaneous healing, the necrotic bone and cartilage seperates from adjacent bone and cartilage and together becomes loose body. To promote healing, the proper treatment is necessary before degenerative change developes. The authors reviewed 11 cases of osteochondritis dissecans which recieved treatment at Severance hospital from January 1972 to December 1981. The results were obtained as follows: 1. The incidence of osteochondritis dissecans in male was a little more frequent than that of female and 50% were observed in the age of 16 to 30 years. 2. The most common symptom and sign was pain and limitation of motion, instability senastion, tenderness, snapping sound in order of frequency. 3. The most common area involved was the knee in 9 cases, 5 cases involved the medial femoral condyle, 4 cases involved the lateral femoral condyle. The ankle and elbow was 1 case for each. 4. Eight(72.7%) of 11 cases had history of trauma. 5. Among 9 cases of knee inlovement, 5 (55.6%) cases were associated with rupture of meniscus. 6. The methods of treatment were as follows. Conservative..................................................................1 Operative Curettage and drilling........................................................6 Excision......................................................................3 Curettage and bone graft.......................................................1 Internal fixation..............................................................1 7. Conservative treatment was performed in one case, but failed. So, all 11 cases recieved operative treatment and obtained satisfactory results in 72.8%.

Birth injury is defined as any condition that affects the fetus adversely during the labor or delivery. These traumatic injuries are subdivided further into those that from hypoxia and mechanical factors. We analyzed 57 patients of birth trauma including fractures, nerve injuries and head injuries during the delivery at Severance Hospital from Jan. 1980. to Dec. 1985 and 24 patients which were transfered from other hospital after delivery and the following results were obtained. 1. The rates of birth trauma in our hospital were 0.36% including clavicle fractures 0.27%,femoral fractures 0.006%, brachial plexus injuries 0.031%, skull fractures 0.025% and intracranial hemorrhage 0.025%. 2. The site of clavicle fractures were all middle one third, and 71.4% of cases were displaced. 3. Five cases of brachial plexus injuries were found, and each type was Erb's palsy 3 cases, Klumpke's palsy 1 case and whole arm palsy 1 case. Three cases were recovered completely and 2 cases were recovered partially. 4. Methods of delivery were as followed; normal delivery 50.6%, breech delivery 3.7%, forcep 7.5%, vacuum 21.0%, and Cesarian section 17.2%. 5. The primipara was 65.4% of the patients of birth trauma. 6. There was no statistical significances in the birth weight, head circumferences, and chest circumferences of the patients comparing to the normal infants.

Soft tissues, which are wide spread in body, are derived from a common primitive mesenchyme and the tumors are arising from them tend to closely resemble the prototype tissues in varying degree. Some soft tissue tumors have benign course, which can be cured by local excision and the others have malignant course being resistant to therapy and resulting in recurrence or metastasis to other organs or tissues. The authors reviewed 241 cases of soft tissue tumors which had been received treatment at Department of Orthopedic Surgery in Severance Hospital, Yonsei University College of Medicine from January 1972 to December 1981. The results were obtained as follows: l. Among 241 cases of soft tissue tumors, 202 (83.8%) were benign and 39 (16.2%) were malignant. 2. The most common benign tumor was lipoma (68.7%) which was followed by hemangioma (8.4%), neurofibroma (6.4%) and schwannoma (5.0%) in decreasing order of incidence. Among malignant tumors, fibrosarcoma (35.9%) and rhabdomyosarcoma (33.3%) were the two most common ones, liposarcom (12.8%) and Kaposi's sarcoma (7.7%) being the next common group of tumors. 3. There was no apparent sex preference in benign soft tissue tumors, but in malignant tumors, male was affected about 3 times more common than female. 4. There was no predilection sites in benign tumors, which in malignant tumors, lower extremity was predominant site of occurence. 5. Metastasis of the malignant tumors was taken placed 13 cases (33.3%) at the time of admission, and the lung was the most common frequent site of metastasis. 6. Most of the benign tumors were treated by local excision, and malignant tumors were treated by wide excision with combination of chemotherapy and/or irradiation. 7. Local recurrence of benign tumors was developed in 12 (5.9%) out of 202 cases. 8. Among 19 cases, on follow up examination had been made, 13 survived more than 1 year and 2 cases longer than 5 years after surgery.

Clonorchiasis procucts diffuse dilatation of the small and medium sized intrahepatic bile ducts and its cholangiogram shows visualization of many bile ducts, especially, tertiary, quaternary, and more peripheral tributaries up to the 6th tributaries. In an attempt to clarify this cholangiographic sign quantitively, we counted the visualized smaller bile ducts in clonorchiasis and compared the number of visualized ducts in normal cholangiogram, recurrent pyogenic chlangitis and carcinoma of the extrahepatic ducts. In clonorchiasis the number of visualized smaller bile ducts was considerably geater than in normal subjects and recurrent pyogenic cholangitis, but there was no singnificant statistical differences in the number of visualized bile duct tributaries between clonorchiasis and carcinoma of the bile ducts. Thus it is considered that too many ducts sign is not a unique cholangiographic finding of clonorchiasis, but we believe that in the presence of this sign with other we l known cholangiographic findings, diagnosis of clonorchiasis is very easy.

The os calcis is fractured more frequently than any other tarsal bone. Fractures involving subtalar joint can, be associated with prolonged and severe disability. So there is no universal agreement in the treatment of these fractures. Calcaneal fractures of 64 feet in 56 patients who were treated at Severance Hospital, Yonsei University College of Medicine from Jan. 1971 to Dec. 1980 were analyzed in clinical and radiological aspects. The results obtained from this study were as follows; 1. Of 56 patients, 46 patients were male and 10 female. 2. The main cause of fractures of calcaneus was a fall from a height in 71.4 percents of cases, and spine injury was associated in 15 patients (26.8%) with calcaneal fractures. 3. The fractures were almostly closed (89.1%). 4. Fractures involving subtalar joint were in 52 feet (81.3%) and Rowe's type 5 were 38 fractures (39.4%). Of these type 5 fractures, 31 fractures were treated by closed reduction and axial pin fixation and then favourable results were obtained. 5. The most common complication after treatment was persistant foot pain. Pain beneath the lateral malleolus was the most common (8 feet), and correlated with the decrease of Bohler's angle.

Carpal tunnel syndrome is most commonly applied to compression neuropathy of the median nerve at the wrist, and is the most cause of buring pain, numbness and tingling in the thumb, index and long fingers, and in the lateral half of the palm, with or without progressive atrophy of the thenar muscles. Fifteen symptomatic hands of 13 patients of the carpal tunnel syndrome managed and operated at the Department of Orthopedic Surgery Severance Hospital from Jan. 1972 to Mar. 1982 were analized in clinical aspect. l. Among 13 patients, 3 were male and 10 were female. 2. Nine patients (69.2%) were affected on dominant hand. 3. Average duration of the symptoms was 17 months. 4. In electromyographic study, conduction delay of the motor fiber of the median nerve was found in 11 cases(73.3%) and sensory fiber in 13 cases(86.6%). Fibrillation of the thenar muscles was found in 11 cases(73.3%). 5. Ten patients, 11 cases were followed up from 11 months to 9 years and 11 months and 72.8% was improved.

Clinical Study

Ossifying fibroma is one of a group of fibro-osseous lesion which arises typically within the jaw bone and only rarely affects the long bones. In 1966, Kempson described two patients with ossifying fibroma of the tibia, noting its unique, aggressive local behavior. This rare lesion resembles monostotic fibrous dysplasia, but can be differentiated from it on histologic and clinical ground. Histologically, ossifying fibroma is characterized by osteoblasstic rimming spicules of bone within a fibrous stroma with evidence of the lamella transformation of bone, and clinically by, frequent recurrence and aggressive progression of the lesion. We experieced three cases of ossifying fibroma, two cases in the tibia and one case in the fibula. In case 1, recurrence was developed after local curettage and bone graft, so reoperation was performed at 11 months after the first opecation. The 2nd case was healed after wide curettage and free vascularized fibula graft, and the 3rd case being followed up after segmental resection of the fibula.

The elbow injury is frequent among the children. The cubitus varus and cubitus valgus deformities are the common late complications of the elbow fracture. Although, these deformities rarely limit elbow function, the correction is frequently requested due to cosmetic problem and/or tardy ulnar nerve palsy. We performed 33 supracondylar closed wedge osteotomies from Jan. 1976 to Jan. 1986, of which 27 cases were cubitus varus, and 6 cases were cubitus valgus at Yonsei University College of Medicine. The results were as follows; 1. Cubitus varus deformity was more common than cubitus valgus; the ratio was 4.5 : 1. 2. The most common initial injury resulted in such angular deformity of elbow was supracondylar fracture of humerus. 3. The duration of plaster-cast immobilization after operation was much longer in cases who operated over 15 years old than under 15 years old. 4. There is no relationship between the duration after initial injury and the result of operation. 5. The result of supracondylar osteotomy was excellent in 11 cases(33.3%), good in 17 cases(51.5 %), and poor in 5 cases(15.2%). 6. Three fourths of cases resulted in excellent and good result were under 15 years old. 7. It is recommeneed that the angular deformity of elbow is corrected early rather than at the conclusion of growth.
