Experimental Study for the Effects of Free Physeal Transplantation to Regain Bone Grwoth after Partial Physeal Injury / 대한정형외과학회잡지

This study is performed to investigate whether free transplanted iliac physis can grow in the resected epiphyseal plate and prevent growth arrest secondary to an injury of epiphyseal plate. Growth arrest, angulation and regeneration of epiphyseal plate after free physeal transplantation from iliac crest in the partial resection of epiphyseal plate on the lateral aspect of the distal femoral epiphysis were analysed in process of time and compared with those of the simple partial resection of epiphyseal plate of distal femur. Seventy-six skeletally immature, three month-old rabbits with an initial weight of about 1200 to 1400gm were used for this study. The following experimental groups were made after partial resection of epiphyseal plate on lateral aspect of distal femoral epiphysis(2×7×3mm). Group A: partial resection alone(19 rabbits); Group B: muscle piece interposition(19 rabbits); Group C: free autogenous iliac crest physeal transplantation (38 rabbits). The opposite side of the leg was used as a control. Animals were killed and examined at the following time-intervals(14, 21, 30, 60 and 90 days after operation). The following results were obtained. 1. In the group of partial resections alone, the bone-brige formation between the femoral epiphysis and metaphysis revealed as early as 14 days, and this bridging was found consistently in all anlmals, which led to the growth arrest and valgus deformity. 2. In the group of muscle piece interpositions, the interposition materials were found temporarily effective for the prevention of epiphysiometaphyseal bone-bridge formation, but the effect was not significant to regain bone growth. 3. Histological studies showed that the grafted physis united with the residual part of the original femoral physis at 14 days after transplantation, and regained its columnar arrangement. The physeal graft appeared to be viable and contribute endochondral bone formation in following section (60, 90 days). 4. In the grodp of free autogenous iliaccrest physeal transplantations, the transplanted physis prevented or minimized the formation of a bone brige, growth arrest, and valgus deformity in most animals. Although not all of the physeal transplants were successful, physeal grafts would be most suceessful method regaining bone growth after focal injury of epiphyseal plate.

The Clinical Observation of the Septic Hip / 대한정형외과학회잡지

A clinical analysis of the septic hip was made on 15 patients, who had been undergone operation in Chung Nam National University Hospital from April, 1977 to Dec., 1978. The following results were obtained. 1. The ratio of male and female was 2.8:1. 2. The most common age group was 7~12 years (5 cases, 33.3%), and next common was 13–20 years (4 cases, 26.7%). 3. The most common causative microorganism was staphylococcus aureus(66.7%). 4. The most common duration of symptoms were less than 5 days (6 cases, 40%), and next common was 6~10 days (4 cases, 27%). 5. The patients, more than 10 days duration of symptoms, had late sequela in 80% but the patients, less than 10 days, had good prognosis in 80%. 6. In authors experience, the most effective treatment for septic hip was early diagnosis and hospitalization, followed by surgical decompression with specific antibiotics.

Disseminated Bone Tuberculosis / 대한정형외과학회잡지

Disseminated bone tuberculosis is a rare manifestation of skeletal tuberculosis in adults in which cystlike lesions occur in the axial skeleton, shoulder, and pelvic girdles. Varied nomenclature applied to the entity of multiple cystic bone lesions in bone tuberculosis have been described in the literature. We experienced 2 cases of disseminated bone tuberculosis in adult.

A Case of Fibromatosis Associated with the Skeletal Change in Childhood / 대한정형외과학회잡지

Fibromatosis in childhood is a rare tumor and also prone to aggressive behavior. This tumor may spread to involve contiguous soft parts and osseous structures, but does not metastasize. We experienced a case of fibromatosis in an 12-year-old giri who complained of palpable masses in the region of the right buttock and right foot. The case has been followed for 6-years since February 1973. Bony change has occured even after several attempts of surgical excision but a distant metastasis has not occured.
