Osteogenesis imperfecta is a heterogenous group of inherited disorder, which has abnormalities in the synthesis of collagen. Among variable clinical manifestations, orthopaedic clinical features are laxity of ligament and deformities arising from frequent fractures or angulation due to skeletal fragility. We had managed 4 cases of osteogensis imperfecta, which were belonged to type IV-B in two cases, type I-A in one, and type I-B in remained one by Sillence classification and they had suffered from recent fractures or deformities due to previous fractures in the long bones of the lower extremities. These patients had been treated with various types of intramedullary nails, such as Bailey-Dubow extensile rod. Rush rod and Kuntcher nail, and the result of intramedullary nailing lead to improvement of walking ability.

The congenital radio-ulnar synostosis is a rare malformation which often completely perevents pronation and supination of the forearm. Recently, this disese has no good result by treatment including various operative techniques. The authors have experience a case of the congenital radio-ulnar synostosis, which was corrected by modified Green method and satisfactory result was obtained.

The stress or fatigue fracture is well known in military medicine, but it is an unusual occurrence in civilian practice. The stress fracture of metatarsal bone is familiar to most, but in the tibia it is unusual. The clinical symptoms of pain, swelling and limping following strenuous activity were seen in the affected lower leg and proceeded radiological evidence of fracture. 17 cases of stress fracture of tibia were investigated in a military hospital between March 1973 and May, 1974. The results of this study are as follows, 1. The fractures mainly occurred in the upper one third of the tibia (13 cases among 17). 2. The cases with only callus formation were more frequent than the cases with fracture line on the tibia (11 cases among 17). 3. If pain occurs in the lower leg after strenuous activity, there should be attention with serial radiological checking.

Leg length discrepancy in children occurs chiefly as an aftermath of poliomyelitis. In spite of immunization, there remain a few infantile paralysis patients with significant leg length discrepancy. The methods to correct leg length inequality have included epiphysiodesis, long bone shortening and growth stimulation. But the limitation of accomplishing equalization by these methods has made it clear that there is a need for an accurate and uncomplicated leg lengthening method. Anderson and others devised a well controlled distraction apparatus and performed surgery upon many, cases with few complications. This study is a report of 7 consecutive patients all operated on by a reverse method, with the application of the Charnley compression apparatus. The results are as follows. 1. Correction of 2. 5 to 4. 5 cm (average 3.4 cm) was achieved. 2. Major complications were delayed union in 5 cases, pin tract infection in 2 cases and nerve injury in 1 case. 3. When either inadequate union or failure of union of the distracted fragments is established in the mature patients, it is suggested that the fragments should be stabilized with bone graft as soon as possible.

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.
