An Experimental Evaluation of Microvascular Grafts / 대한정형외과학회잡지

Vascular grafts are often required in clinical stiuations to bridge arterial or venous grafts. Numerous studies exist in the literature concerning the results of such arterial and venous graft of relatively large vessels. There are only a few reports dealing with experimental microvascular grafts. Histopathological features of the grafted vessels were studied after autogenous venous grafts,autogenous arterial grafts and venous allografts using microsurgical techniques. The results were summerized as follow. 1. The patency rate of grafted vessels by microsurgical techniques was 86.8%. 2. In autogenous venous grafts histopathological changes occur later, and to a less pronounced degree, than that in autogenous arterial grafts. 3. Venous allografts showed severe acute inflammatory reaction throughout the layer at 3~7 days postoperatively, but histopathological features of grafted vessels of autografts and venous allografts' did not differ each other in later results. 4. Autogenous venous grafts, autogenous arterial gtafts and venous allografts persist as living sucture but undergo certain histological changes consisting of fibrous reinforcement. 5. It may be said that histological examination of the specimen led general conclusion that the most useful microvascular graft to reestablish circulation of damaged vessels is the autogenous venous graft, but autogenous arterial graft and venous allograft are also applicable when autogenous venous tissue is not available.

A Clinical Study on the Fractures of the Calcaneus / 대한정형외과학회잡지

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.

Spondylometaphyseal Dyslpasia

There sibs with identical features of short-limbed dwarfism, a normal skull and face and normal intelligence are described. On the basis of the radiological and clinical characteristics, the condition must be included within the group of Spondylomephyseal dysplasia. In contract to the familial cases described up to now in which the mode of inheritance was autosomal dominant, the trait in the three children described here was transmitted as autosomal recessive.

Progressive Muscular Dystrophy: A Case Report / 대한정형외과학회잡지

Progressive Muscular Dystrophy is a hereditary disorder characterized by progressive weakness and wasting of muscules. The etiology of muscular dystrophy is unknown, and no from of pharmacological treatment is considered effective. We report 2 cases of progressive muscular dystrophy occuring in a family, which were diagnosed by clinical findings, serum enzyme study and electromyography.

Marfan Syndrome Occurring in One Family / 대한정형외과학회잡지

Marfan syndrome is an uncommon congenital disease originally described by Marfan in 1896. It is inherited as an autosomal dominant trait and can affect the tissues of mesodermal origin, mainly skeletal, ocular, and cardio-vascular systems. We report 4 cases of Marfan syndrome occurring in one family, one of which was found to have an acute attack of glaucoma and underwent extract operation of a right dislocated lens. A brief summary of the literature is submitted.

Clinical Observation of Acromioclavicular Seperation / 대한정형외과학회잡지

Twenty four cases of acromioclavicular seperation were admitted and treated at Severance Hospital, Yonsei University from October 1964 to September 1975. Of these, six cases were subluxations and eighteen cases were dislocations. Acromioclavicular joint injury is relatively rare and there are many methods of treatment. In our cases, all the six subluxations and seven of the eighteen dislocations were treated by conservative method, while eleven of the eighteen dislocations were treated by operative method. The results of all the subluxated cases were satisfactory. In cases of dislocation, the results were considerably better in operated cases with Weavers method.

Myositis Ossificans Progressiva: A Case Report / 대한정형외과학회잡지

Myositis ossificans progressiva is a rare disease characterized by the formation of areas of calcification in the interstitial connective tissue of muscles, tendons, ligaments, fascia, and aponeuroses. There may be exacerbations and remissions of the disease, but the general course is an insidious loss of body motion, affecting especially the neck, spine and upper extremities and, rarely, the hips and lower extremities. It is commonly associated with various congenital anomalies. The cause is unknown and there is no known effective treatment. Myositis ossificans progressiva associated with brachydactyly of both great toes, in a 34 year old femaIe, is presented with a review of the literature. Chief complaints were ankylosis of the left knee and hip of 9 years duration. We performed biopsy of tubular bone which is placed antero-lateral side of the left knee.

A Case of Aneurysmal Bone Cyst / 대한정형외과학회잡지

Aneurysmal bone cyst is an uncommon tumor-like lesion of the bone, containing distended channels or cavities filled with blood. This case, a eighteen years old female, complained of pain and swelling in the right lateral aspect of thigh. Roentgenograms showed a ballooned-out distension of the shaft of the femur, eccentric buldging of the cortex and soap-bubble appearance of interior of the lesion. The case was treated with radical curettage and autogenous bone graft with bone chips which were taken from the iliac wing. Pathological examination grossly and microscopically revealed an aneurysmal bone cyst. Patient made an uneventful recovery, and 11 months later she had no complaints and no evidence of recurrence.
