Author take off the pelvic bone from the cadaver and made the accruate reconstructed the pelvic bone as well as normal bone. Then author setted the pelvic bone into the specialized acrylic globe as the normal person erect position. For the acetabular posterior wall, projected the radiologic beam from the 0°to 45°cephalad direction and then pelvic bone rotated internally 0°~45°, each section is 5°. For acetabular anterior wall, projected the radiologic beam from 0° to 45° caudal direction and pelvic bone rotated externally 0°~45°, each section is 5° too. From the pelvic bone experiments, author get on the good radiologic angle for acetabular anterior and posterior wall. Ane then make the radiologic projection for normal person as the pelvic experiment. In pelvic bone model experiment, For acetabular anterior wall and anterior colum, external rotation 20°~30° caudal tilting 30°~45° angle projection has good visualization. For acetabular posterior wall and posterior column (including anterior column partially), internal rotation 15°~20° cephalad tilting 15°~30°angle projection has the good visualization. In normal person experiment, For acetabular anterior wall and anterior column, external rotation 20°caudal tilting 30°angle projection shows the good visualization. For acetabular posterior wall and column (including anterior column partially) internal rotation 20°cephalad tilting 30°angle projection shows good visualization. From the pelvic bone model and normal person experiments, the following conclusion are obtained. 1. For posterior wall and posterior column(including anterior column partially), internal rotation 20°, cephalad tilting 30°view is good. 2. For anterior wall and anterior column, external rotation 20°, caudal tilting 30°view is good.

The anterior cruciate ligament injury is one of the most common ligament injury of the knee joint, and anterior cruciate ligament is as important structure for stabilization as a primary restraint. Noyes reported that the diagnosis of a tek of the anterior cruciate ligament was made by the original treating physician in only 6.8%. And there are many controversies in its treatment. It is certain thatearly diagnosis and treatment are th most important clue. Authors studied 48 patients of isolated anterior cruciate ligament injury who were diagnosed by same physician from Jan. 1983 to Dec. 1985 after follow ups ranging from six mnths to 4 years, average beimng one year and two months. The results were as followings: 1. The most common cause was sports injury. 2. The most common sign and symptom were hemarthrosis in acute injury and giving way in chronic injury. 3. Anterior drawer test without anesthesia had 25% of diagnostic accuracy but pivot shift test under anesthesia 95.8%. 4. 31 cases in 48 cases (64.8) had associated meniscal injury. 5. In acute torn ACL, the primajy repair was preparable but conservative treatment with arthroscopic partial menisectomy was eful in chronic case.

The phenomenon of Myotonia consist in a failure of voluntary muscles to relax immediately when voluntary innervation ceases. The stiffness is accentuated by cold and relieved by exercise, while generalized muscle weakness and atrophy (or not commonly hypertrophy of muscle) is common. Myotonia is a feature of four principal clinical syndromes which have been classified myotonia congenita (Thomsens disease), myotonia atrophica (Steinerts disease), paramyotonia and myotonia and myotonia acquisita by Walton et al. We report here a forty six years old male of myotonia atrophica (Dystrophia myotonia, Steinerts disease) who presents bilateral cataracts, frontal baldness, gonadal atrophy, facial myopathy, sterno-cleidomastoid muscle atrophy and a progressive generalized myopathy of peripheral distribution in the limbs.

The authors did clinical analysis for 37 cases, ranging from 5 to 13 year old of age and following result obtained. 1. In group I partial involved type had brightful prognosis even in the neglected the cases. 2. Ischeal brace did not give any help to group II & III but in group I, it gave some help to the prognosis. 3. In untreated cases of old age group developed early arthritic changes. 4. The inital radiological bony changes in early L-C-P. cases was the demineralization of the subchondral area and subsequently subohondral vaccum phenomena followed.

During the last 18 years only a small number of successful replantation of lower extremities severed by trauma have been reported. In this paper we report the first successful case of replantation of completely amputated thigh In Korean literature. A 31-year-old man was admitted to Kyung Hee Unlversity Hospital on February 27th 1976, approximately 1 hour after accident in which the left thigh was completely amputated 15 cm above the knee joint. Circulation was restored 6 hours after amputation through anastomosis of the femoral vein, artery, great saphenous vein, profunda femoris artery and vein. The continuity of sciatic nerve was reestablished by secondary furnicular suture 7 week after injury. About 4 years and 7 months after injury the patient could walk without pain and returned to his occupation. Thre was a almost complete return of motor and sensory function of the posterior tibial nerve.

It is generally accepted that fractures should be treated by closed methods, however for certain femoral fractures in adults, closed methods yields an unacceptable high incidence of nounlon, malunion, delayed unlon, and disability. For these fractures various methods of open reduction and internal fixation have been recommended, but unfortunately, there are frequent reports of complications and failures. The recently developed association for study of Internal fixation (ASIF) compression plating apparatus, seems to satisfy the basic objectives of internal flxatlons: namely

Antibiotic-acrylic bone cement composites demonstrated antibacterial activity as a result of diffusion of antibiotic from bone cement into surrounding enviroment, accordingly, the use of antibiotic incorporation to bone cement for the prevention and treatment of infection after joint surgery replacement has been adovocated. Early report of clinical success by using antibiotic-acrylic bone cement composites are encouraging. Our authors applied this concept to the treatment of chronic osteomyelitis. Antibiotic contained with bone cement was chosen by sensitivity test on pus culture finding. Seven cases of chronic osteomyelitia treated by using antibiotic-acrylic bone eement composites were .studied in the Department of Orthopaedic Surgery, Kyung Hee University Hospital from July 1979 to March 1981. The follow-up period was from 3 months tc 22 months. The results were as follow: 1. Six cases showed no evidence of recurrence except one by using antibiotic acrylic bone cement composites. 2. The impregantion of antibiotic in acrylic bone cement shall be regarded to be effective in increasing the local antibacterial activity by leaching the antibiotic into surrounding tissue over a period continiously in treatment of chronic osteomyelitis. 3. The use of antibiotic-acrylic bone cement compositea into dead space by saucerization are consid- ered an one such approach to the decrease of dead space. 4. The impregnation of antibiotic in acrylic bone cement is regarded a new concept in treatment of chronic osteomyelitis.

Bone scan measuring bone metastasis were analysed in fifty five patients diagnosed as malignant tumor, seven were primary bone tumor and forty eight were metastatic tumor, who treated in Kyung Hee Hospital from March 1981 to January 1982. The results were as follows: l. In 55 patients, positive bone scan were found in 76.4% of the patients and positive X-ray were found in 56.4%. 2. 7 patients with primary bone tumor showed all positive bone scan, 45 patients with metastatic tumor showed positive bone in 72.9%. 3. Among the patients with metastatic tumor who no clinical symptoms, positive bone scan were found in 59.3% and positive X-ray in 26%. 4. Most common metastatic site was femur in primary bone tumor and vertebra in metastatic tumor. 5. In 48 patients of metastatic tumor, positive bone scan within negative X-ray were found in 56%, negative bone scan within positve X-ray were found in 5%. 6 The lesions showed clod area on bone scan were considered of positive finding as compared with clinical symptom and X-ray finding.

A tibial segment in 3cm length with vascular pedicle and periosteum (Living bone graft) and the segment without vascular pedicle and periosteum (Dead bone graft) was obtained from twenty four rabbits, being divided into two group respectively. Then it was replaced with the segmental bone in the initial osteomized defect. The grade of healing and the time factor required to accomplish the repair of resected segmental tibial transplant was determined at one week interval during one to eight weeks, aimed by the,comparative studies of microscopic (gross), radiological as well as histological observation during the healing process. The average time of callus formation in the living bone graft was approximately two weeks, as compared to four weeks of the dead bone graft. Radiographically the average time of bone union in the living bone graft was four weeks, compared with seven weeks for the dead bone graft. The living bone graft was permitted to the healing process of the simple fracture at the graft-recipient bone juncture, in the contrast with the dead bone graft it was united with replacement of the grafted bone by new bone, so called “creeping substitution”.

The normal vascularization of peripheral nervesand the vascular factor in peripheral nerve les ons have regained increasing interest among surgeons. So, several attempts have been made to assess the relative importance of the vasa nervorum and intrinsic longitudinal vascular plexuses of nerve in maintaining the blood supply.of a segment of nerve trunk. The purpose of our experiment was to determine in laboratory animals the maximum extent to which a nerve can be mobilized without impairing its vascular supply so much that nerve function is jeopardized. All our studies were carried out on both sides of the sciatic-tibial nerve of thirty-two rabbit which were anesthetized intraperitoneally with urethane. The experimental procedure differed in three groups, Group I in which the sciatic nerve was mobilized 3 cm in length, Group II was mob lized 7 cm length and Group III was mobilized 10cm long. The tibialis post. muscles of each group were analyzed at intervals ot 1,2,4,6 and 8 weeks after neurolysis. Each muscles were examined grossly and histologically after hematoxylin and eosin staining. Experimental studies showed that a peripheral nerve is a well vascularized structure with a considerable reserve capacity in its microirculation. The intrinsic collateral system is well developeed and experimental deta supported the view that peripheral nerves may be mobilized over a cons derable length with or the only minium interference with their microvascular flow. The results were as follows: 1. The first evidence of histologic change in the muscle fibers was in the sarcolemmal neclei. 2. Localized atrophy of muscle fibers were observed at the six weeks after neurolysis. 3. With increasing length of neurolysis, abnormal finding were developed in early stage. 4. Massive atrophy of muscle fibers were noted in the muscle fibers which neurolysed more 7cm.
