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.

Extraskeletal Neoplasm Resembling Ewings Sarcoma was firstly reported with comprehensive review of 39 cases by L. Angervall and F.M. Enzinger in 1975. The tumors chiefly affected young adults and most commonly involved the soft tissue of lower extremity. Microscopically, they were consisted of solidly packed small, round or ovoid cells arranged in sheets or lobules, which were indistinguishable from those of the Ewings sarcoma of bone. The authors recently experienced a soft tissue sarcoma occurring in deltoid area of young male patient, which was diagnosed extraskeletal neoplasm resembling Ewings sarcoma. The case review is presented.

The goals of hip arthroplasty have been to eliminate pain, decrease deformity, increase morbility and obtain stabiIity. Currently total hip replacement is the best avaliable procedure to accomplish these goals. A prospective study of total hip arthroplasty was begun at the orthopedic dept of Kyung Hee Medical College in 1974. Between May, 1974 and June, 1977. 69 total hip replacements of the Charnley type, the Trapesoidal-28 type and the Muller type were peformed by the authors. Of the 60 Patients involved in this study, 9 had bilateral operations. The Charnley type Prosthetic device was used in 56 cases, the Trapesoidal-28 type in 7 cases and the Muller type in 6 cases. Complications included wire breakage, dislocation, loosening, femur shaft perforation, nonunion of greater-trochanter, acetabular protrusion, transient femoral nerve palsy, femur shaft fracture, infection, socket lateralization, ectopic bone formation and death. In 59 patients of the 60 patients, 53 patients felt that they were definitely improved, 5 patients felt their condition was unchanged and 1 patient felt her condition was worse.

The injury of the epiphysis or epiphyseal plate produces undesirable effects on the normal growth of the bone, such as bone bridge, growth arrest and angular deformity. Authors performed vascularized fibular epiphysis and epiphyseal plate transplantation in 7 years old girl, who received the excision of the exostosis on distal ulna, followed by progressive varus deformity of right forearm and growth arrest of distal ulna.

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.

A case of intraneural ganglion of the peroneal nerve in an eleven year old boy is reported. The cystic ganglion, 5.5cm×2.0×1.0cm, which was located at the region of the bifurcation of the peroneal nerve without communication of any joint or bursa, was excised, The ganglion was recurred at 6 weeks after the first excision.

46 knees with injured meniscus diagnosed by the use of history and physical examination as well as by arthrography were meniscectomized from January in 1974 to June in 1978. Statistical analysis of data obtained from the histories, physical examinations and arthrographic studies of 46 knees with a mean follow up 6 months after meniscectomy revealed as follows. 1. Lateral meniscus injuries were higher incidence than medial meniscus. 2. In the posterior horn of the medial meniscus and in the middle third of the lateral meniscus on the injured location were more frequently encountered. 3. To compare the results of twe methods of diagnosis were obtained with 67% accuracy by the use of history and physical examination and with 85% accuracy by arthrography 4. We should be able to diagnosis with 91% armed with a history and physical examination and an arthrogram. 5. As being the excellent results after meniscectomy were classified with 78%.

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.

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”.
