The suture techniques to anastomose successfully small vassels of 1mm in diameter were continuous suture and interrupted suture, and patency rate of them has been estabilished by orthopaedic surgeon. In 1962, Chase and Schwarz reported better results with interrupted suture than with a continuous suture, Firsching reported less time using with continuous suture than with interrupted suture, but no difference in flow rate, in 1984 Lilly reported that interrupted suture does no result in stenosis of venous end to end anastomoses by continuous suturing technique, Mao reported that there was no statically significant difference between two suture methods in patency rate. The authors have experimentally studied the patency rate and histopathological findings of two suture techniques in the 20 Newzealand white rabbit at the department of Orthopaedic Surgery, Hanyang University Hospital and can be obtained the following results. l. In arterial patency, the interrupted suture and continuous suture were 100% in rate and patency rate in veins were 95% in interrupted suture and 75% in continuous suture. 2. Subintimal hyperplasia occured earlier in arteries than in veins and it may be due to the medial component of vessel. 3. In anastomoses of small vessel the accurate apposition of cut vessels edges decreased the thrombi formation of vessel.

The human hand is a highly sophisticated tool of sensibility and prehension, and the reconstruction of injured hands are essential to not only reconstruct of hand function but also reconstruct of body. Seven cases of tendocutaneous flap, a case of osteocutaneous flap, nine cases of thumb reconstruction with a free neurovascular wrap-around flap from the big toe, two cases of second toe-to-index trander, and a case of left ring finger to right index finger transfer were performed at the Department of Orthopedic Surgery of Hanyang University Hospital, and satisfactory results were obtained both comsmetically and functionally.

Keratoacanthoma (KA) is a rapidly growing cutaneous tumor and is difficult to distinguish from squamous cell carcinoma (SCC) on histomorphology alone. In the present study, we compared the clinicopathological and immunohistochemical findings using antibodies for p21 (WAF-1/CIP1), p53, laminin, and Ki-67 proteins in 27 cases of KA and 31 cases of well differentiated SCC. KA was characterized by occurrence in sun-exposed skin, shorter duration, and smaller size. Expression of p21 protein was increased according to the maturation and involution of KA, but there was no statistical significance. Expression of Ki-67 was decreased in the involutional stage of KA than in SCC (p<0.05). But p53 protein and Ki-67 were expressed in the cells at the periphery of both KA and SCC. The immunoexpression pattern of p53 and Ki-67 suggests that proliferative activities of the two lesions are similar. Laminin was present in the infiltrative cell nests of fully developed and involutional stages of KA, and it may be related to the healing process of KA. In conclusion, it is suggested that the degree of proliferative activity in the proliferative and fully developed stages of KA is similar to that of SCC and that p21 gene expression represents the differentiation property of KA and may be associated with its regression.

The present study is an observation of 678 cases of children's fractures; which was treated in the Dept. of Orthopedic Surgery, inchon Christian Hospital, for the past ten years, from 1968 to 1978. The peak age was in from 5 years to 6 years. The sex ratio was 2.9 male to 1 female. The ratio between the right and left extremity was nearly equal. The frequency of fracture of the upper extermity was silghtly dominant then lower extremity. The cause of fracture was fall down Injury in nealy 70% of all cases. The epiphyseal Injury was noted as 16.8% of total orthapedic cases. The most common type of Salter & Harris Classiflcation was type II or 56.1%. Mostly all of children's fractures were treated by closed method, and others were treated by open reduction. Complication Included 29 cases of changed carring angle 18 cases of traumatic arthritis and 8 cases of malunlted supracondylar fracture and 3 cases of postoperative Infections and 2 cases of radial nerve palsy and 3 cases of delayed ulnar nerve palsy of the elbow. In fractures of the femur, 3 cases of the peroneal nerve palsy and 2 cases of leg longth discrepancy was noted. Brief discussion and review of Iiterature is presented.

A case of severe osteoarthritic patient of both hip treated with McKee-Farrar total endoprosthesis on one hip is reported. The introduction, indication, procedure of the surgery and the use of the self curing acrylic cement were reviewed briefly. The hip following the surgery, even though the follow-up duration is short, showed exceIlent result.
