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.

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.

The arthrodesis of the hip is the only certain method for eliminating pain and providing stability in young and middle aged adults. The first used arthrodesis in old congenital dislocation was reported by Heusner, Lampugnani, and Alert as early as 1885 according to Nove-Josserand. The various papers published on this operation appear to be concerned mainly with surgical methods and the frequency of bone healing, rather than with loss of function and its causes. The purpose of this study is to evaluate function of the arthrodesed hip especially the relationship between position of the hip and its daily use. The author studied arthrodesis of the hip clinically in 89 cases of arthrodesed patients, admitted to the Orthopedic Department of Severance Hospital during the 14 years from June 1957 until May 1970. The auther also studied 40 cases which confirmed sound bony ankylosis of the hip by X-ray examination. The follow-up included a careful inquiry into the patients ability to use the fixed hip in various functions of daily life. The results are as follows. 1. The average age of the patients at the time of operation was 16.9 years and tuberculosis of the hip was the most common cause 83(93%) of arthrodesis. 2. The most common type of operation in this series was intraarticular arthrodesis 67(75.3%), and the fusion rate was relatively good in intra & extraarticular arthrodesis 20(85.5%). 3. The average length of follow-up was 3.9 years. The average position of the arthrodesed hip was 37.7 degrees of flexion, 9.1 degrees of abduction and neutral rotation. Actual shortening of the leg averaged 3.8cm. 4. The gait was poor in the group which had 5cm shortening of the leg and was in 43 degrees of flexion for the arthrodesed hip. 5. The ability to sit and defecate in the ordinary toilet was satisfactory when there was 39 degrees of flexion or more for the arhrodesed hip. 6. 10 patients (25%) had back pain and 12 patients (30%) had mild scoliosis. Average Ferguson angle was 47.8 degrees and the Line of Weight Thrust showed over 40 degrees. 7. The ideal hip position of arthrodiesis in Koreans was assumed to be under 40 degrees of flexion, some degrees of abduction and no rotation.
