Many injuries of the hand have been occurred in these days because of frequent industrial hazards and frequent handling of tools in modern civilizing life. A voluminous amount of literature has been recently concerned with many problems and questions posed by tendon surgery. Many investigations have been devoted to discussion of suture materials, tendon suturing, grafting, healing, rate of healing, nutrition and related clinical and laboratory endeavors. Whatever the material, the aim of tendon suture is not only restoration of a strong mechanical union but also sliding function of the tendon. Thus the question has always been after what delay active mobilization can be allowed or encouraged. If immobilization allows fibroblasts to invade the tendon extremities and form a scar mass, its prolong leads to adhesion and loss of normal sliding. On the other hand, one can admit that early passive or active mobilization, even if only over a short distance may distend the adherences and transform them into a kind of mesotenon assuring a better sliding function. Before permiting early motion, several factors must be considered such as tensile strength of the suture material, holding power of the suture for the tnedon, bulkiness of the repair and stress that must be withstood. Thus it is the purpose of this study to analysis and comparing of tensile strength and morphological changes in the healing process of tendon tissues by different suturing methods. For this study deep flexor tendon on third toe of adult chicken with an initial weight of about 2Kg was used. The animals were divided into 4 sutured groups which including different suturing methods. Suturing methods used were interrupted suture, Bunnels lace suture, Kessler suture and end-weave anastomosis, which have been applied frequently in tendon surgery. All suture material used were the same size 4-0 Ethilon which has least tissue reaction but high strength. In the animals, after the sharp dissection of the distal portion of the deep flexor tendon on third toe, the tendon stumps were approximated and sutured by 4 different methods. Then a long leg cast in the position of flexion of the foot and ankle joint was applied. On operation day and fifth, tenth, fourteenth and twenty-first postoperative day; the animals were sacrified and the specimens were gained. The measurement of the tensile strength of the sutured tendon was performed through the use of force transducer with the recording of polygraph for permitting continous monitoring of a progressively increasing load until the failure of tendon repair. Specimens stained with hematoxylin-eosin and Massontrichrome stain were observed during 42 days after operation. The findings are as follows. 1. The tensile strength of sutured tendon groups using interrupted suture, Kessler suture, and end-weave anastomosis were reduced maximally on fifth postoperative fay and the tensile strength of Bunnel's lace suture group was reduced maximally on tenth postoperative day. Thereafter the strength was increased progressively on entire experimental groups. 2. The tensile strength of end-weave anastomosis group was the strongest among all experimental groups during experimental period. 3. Just after the repairs of injured tendon, the order of strength was Bunnel. Kessler and inerrupted suture but the strength was nearly approximated on 21st day. 4. The morphological healing process of interrupted and Kessler suture were better than that of Nunnel and end-weave suture. From these morphological and physical results, it is suggested that Kessler suture is better suturing method in tendon repair.

In recent years, the incidence of traumatic dislocation of the hip joint appears to be on the increase, year by year, as the rate of traffic and industrial accidents increases. To prevent complications after dislocation of the hip, many authors have pointed out the importance of the early accurate reduction. But many authors have advocated different methods for aftercare treatment. In this paper, the author has reviewed 34 patients of traumatic disolocation of the hip who had been hospitalized and treated at Hanyang University Hospital from May 1972 to Dec. 1980. It was possible to follow 21 of these patients for an average followup period of 54 months. With this study, the following results were obtained. l. Of 34 patients, 31 patients were male and 3 were female. The prevalent age distribution was from 21 to 30 years of age 12 patients (35.3%) showing this distribution. 2. 30 (88.4%) of 34 dislocations of the hip were the result of traffic accidents, 22 of these being auto accidents. 3. The order of incidence according to the Thompson-Epstein classification is; posterior type I (44.1%), III (23.5%) and type II (11.8%). 4. 28 (82.4%) dislocations of the hip were complicated by multiple injuries at other sites. The most common site of associated injury was the ipsilateral lower extremity, which occurred in 15 patients. 5. 27 closed reductions, 5 open reductions and 1 prosthetic replacement of femoral head were performed, and 24 (88.9%) of 27 closed reductions were performed within 24 hours. 6. By Thompson-Epstein method, the author evaluated 21 patients who could be followed for an average of 54 months, and so obtained excellent or good results in 16 patients (71.4%) and fair or poor results in 5 patients (28.6%). Of these 21 patients, 13 patients who were performed closed reduction with 24 hours were results of excellent of good. 7. As complications avascular necrosis, traumatic arthritis and ectopic ossification developed in one, four and three patients respectively. In addition 5 patients developed sciatic nerve injuries, 3 of these recovered completely.

Fractures of the neck of the femur in children are so rare that none has a great experience of them. Therefore the literature is scanty and no detailed study of a large series of cases can be found. Generally there were several differens between femoral neck fracture of adult and child. Those are rare incidence, the mechanism of fracture, different blood supply of femoral head, difficulty discision of definitive treatment and high incidence of complications. In this report, we presented 4 cases. One of them was the dispiaced fracture and was treated with conservative method. The other 3 cases were the displaced fractures and were treated with operative method. Relatively good results were obtained.

The cleidocranial dysostosis is relatively rare congenital and familial disorder with autosomal dominant inheritance. After the first report of a case of this was that of Cutter in 1870, which was quoted from Soule, A., in 1946, Marie and Sainton supplied the name of the Cleidocranial dysostosis with the report of 2 cases of this in 1897. Since that time approximately 350 cases have been described in the literature. This condition is characterized by deficient formation of the clavicle, delayed and imperfect ossification of the cranium and less often involvement of other bones, We experienced 2 cases of this and reported them in this paper with a brief review of the literatures.

Traumatic dislocation of the hip with ipsilateral femoral shaft fracture was a rare injury. In this paper, 3 cases of these combined injuries are reported together with a review of the literature. After closed reduction of the two dislocated hips, the shaft fractures were treated, one with the Kiintscher nail, and the other with blade plate & screws. The remain was treated by Watson-Jones method. In the follow-up study, a fair result in one case and good results in two cases were obtained. Complications in 2 cases were peroneal nerve palsy. One case had pathologic ossification and one developed traumatic arthritis.

There were many acceptable theories, which described the etiology, incidence, classification, operation time and operative method for the congenital hand anomalies, but so much troublesomes in these aspects were remained. So authors reviewed 57 cases in 49 patients with the congenital hand anomalies, managed at Department of Orthopaedic Surgery, Hanyang University Hospital from Feb. 1972 to Apr. 1986, and the results obtained were as follows. The sex incidence was 26 male(53%) and 23 female(47%) among 49 patients and the ratio between male and female was 1.1: 1. Right hands were involved in 26 patients (53%), left hands were in 15 patients(31%), and both hands were in 8 patients(16%). 2. The most common anomalies among 59 cases in 49 patients were polydactyly (27 cases, 47%) The next anomalies were trigger thumb (25 cases, 44%), syndactyly (3 cases, 5 %), macrodactyly (1 case, 2%), and cleft hand (1 case, 2%) in that orders. 3. The associated congenital anomalies and the maternal histories during pregnancy were not specific. 4. The treatment was stressed upon the functional improvement than the cosmetic one.

BACKGROUNDS: Intestinal obstruction is one of the main causes of neonatal operations. It is caused by congenital factors, inherited diseases, and acquired diseases. A study was made to understand the status of neonatal intestinal obstruction cases at our hospital. METHODS: This was a clinical analysis of 53 cases of neonatal intestinal obstruction which had been experienced from March 1992 to February 1998 at the Department of General surgery, Sung-Ae General Hospital. RESULTS: 1) Operations for neonatal intestinal obstructions accounted for 42.4% of all neonatal operations. 2) There were 38 males and 15 females; the male-to-female ratio was 2.5:1. 3) Gestational period of 9 cases (16.9%) was less than 36 weeks and the weight in 10 cases (18.8%) wre below 2,500 gm at birth. 4) The main clinical symptoms on admission were vomiting or abdominal distension. 5) There were 49 cases (92.4%) of mechanical obstruction and 4 cases of a paralytic ileus. 6) Associated anomalies were present in 9 cases (16.9%). 7) The postoperative complication and motality rates were 30.1% and 7.5% respectively. CONCLUSIONS: Our clinical data might provide clinical suspicisions leading to early diagnosis and treatment.
