The growth plate is responsible for longitudinal bone growth and is involved in 6–15% of children's fracture. Of these injuries, 25–35% have been reported to result in some shortening or deformity, but in only 10% are the deformities sufficiently severe to lead to functional problems. The problem of repair of a demaged growth plate in children has never been adequately solved. The purpose of this study is to clarify that allograft of cultured chondrocytes can survive in the growth plate defect and can prevent the angular deformity by avoiding the formation of bone bridge. The chondrocytes were obtained from the rib cartilage of rabbit weighing 500g. The chondrocytes were cultured by socalled micromass culture method. The rabbits were divided two groups; the group I in which medial proximal tibial growth plate was destroyed, and the group II in which the cultured chondrocytes were transplanted into the right medial proximal tibial physeal defect. Each group has 10 rabbits. The tibial growth was observed grossly, radiologically and histologically until 16 weeks after graft. The angular deformity was observed from 3 weeks after operation and histologically the fusion of growth plate was observed in all of group I. In group II, there were no angular deformity and no fusion of growth plate in 7 out of 10 rabbits. Allografted cultured chondrocytes survived and produced matrix in the physeal defects. Through this study it was inferred that allograft transplantation of cultued chondrocytes in the iatrogenical physeal defect is a useful method to keep the physeal growth without cessation. However, further studies will be necessary to prove that the longitudinal growth potential resides in the transplanted chondrocytes as growth plate cartilage.

Kyphosis and scoliosis develops from various causes, Tuberculosis is the main cause of kyphosis and spinal deformity in Korea. Such spinal deformities are frequently accompanied by cardiac and respiratory changes. In 1969, Westgate and Moe reported that, when a kyphoscoliotic patient dies, he dies because of cardio-respiratory failure and not because of skeletal abnormality, and, in 1968, Nilsonne and Lundgren reported that the mortality in patients with severe spinal deformity was twice as high as in normal persons, and that heart or lung disease was the main cause of death. One must consider the cardiopulmonary status when treating patients with severe spinal deformities. While there are numerous reports on pulmonary dysfunction due to scoliosis or kyphoscoliosis, studies on pulmonary function of patients with tuberculous kyphosis are surprisingly few. The authors investigated the correlation of the degrees of curvature and pulmonary function on 17 cases of adults with tuberculous kyphosis and compared the results with those of the children reported in 1972 by Moon and Lee. The results of this study are as follows: 1. The over-all mean degree of kyphosis was 92.6 (Salters angle). Vital capacity was 63.1% and maximum breathing capacity 61.7% of the predicted normal value. 2. Vital capacity showed a negative correlation with the degree of kyphotic curvature; i. e. the greater the spinal curvature, the less the vital capacity and vice versa, R=0.45, P=<0.1, but there was no correlation between maximum breathing capacity and the degree of curvature. 3. Vital capacity showed a relatively significant positive correlation with maximum breathing capacity as kyphosis increased. 4. The over-all mean tidal volume increased 9.3% of the normal predicted value. 5. When comparing with the pulmonary function of the children with same level and same degree of kyphosis, the adults had significant decrease in vital capacity and maximum breathing capacity, but had increased tidal volume. Such disparity was more prominent in the thoracic spine than in the lumbar spine and when the kyphotic curvature was greater than when less. 6. Timed vital capacity was within normal limits in spite of kyphotic changes of the spine.

Nowadays the clinical impression in Korea is that genu varum uncommon though there was high incidence of this deformity by vitamin D deficiency in the early 1900. Authors reviewed the case histories and x-ray of 18 patients treated for this condition at the Dept. of Orthopaedics, St. Mary's hospital for past 5 years: 17 patients were under 5 years of age. 12 patients had rachitic bowIeg and among them four had active ricket. Six patients had physiologic bowleg deformity. Classification in four grades according to severity of bowleg is attempted. Among the cases eleven patients having less than 10 degree of bowleg treated conservatively with good end result, but corrective osteotomy is routinely scheduled for seven patients having bowleg of knee over 10 degree and resist to treatment. Lasting it is stressed that physiologic bowleg shoud be distinguished from pathologic one. Diagnosis of bow leg can not be made before age of 2–3 years, that is, before transitional phase of development of knee angle.

It has been well known that the incidence of delayed or nonunion of tibial shaft fracture is high and in order to improve methods of treatment and to get satisfactory final results in these fractures, it is important to find out as early as possible whether the fracture is healing normally or not. The fracture healing is closely related to the circulatory conditions at the fracture site, however, in contrast to animal experiments it is impossible to visualize directly the circulatory conditions at the fracture site. There have been many efforts to visualize indirectly these vascular re-establishments through angiography. Kaski(1974) reported a paper concerning osteomedullography of tibial fracture with phlebocompression and noticed 5 types of veins related to the process of healing. We performed 54 cases of osteomedullography in 41 tibial fracture at 3 months after treatment and the following results were obtained: 1. The sinusoidal vein in the proximal fragment was observed most frequently and the next were intra-osseous crossing vein, periosteal callus vein, ascending branch of main efferent vein, and periosteal veins of proximal fragment in decreasig frequency. 2. The rate of positive finding in osteomedullography at 3 months after treatment was lower, and periosteal callus veins were observed more frequently in the group treated with only cast immobilization than in the group treated with plate and screws. 3. In the group treated with compression plate and screws, osteomedullographs were positive in all 3 cases within 3 months after operation and sinusoidal veins in the proximal fragment were visualized in all cases, however periosteal callus vein was not visualized at all. 4. After bone graft, the differentiation of periosteal callus from grafted bone was not easy in plain X-ray film, but osteomedullography was very useful in these cases. Positive findings were noticed in 2~3 months in all cases following bone graft. 5. The authors found that the ideal time of performing osteomedullography was 3 months following treatment. If found to be negative after 4 months following treatment, bone graft was necessary.

Fifty seven consecutive trochanteric hip fracture treated with Smith-Petersen nail and Thornton plate who were treated at the Department of Orthopedic Surgery, St. Marys Hospital Catholic Medical College, during the period of January 1969 to September 1975 were reviewed. This covered a period of six years and nine months. Of the fifty seven cases treated with this method, only thirty four cases were able to be analysed completely. Of these thirty four cases, in two cases the nail penetrated to the hip joint, four cases showed a loosening bolt of the S-P nail, one case involved a delayed union and three cases resulted in malunion, showing a total failure rate of 29.4%. In addition, four cases of intertrochanteric hip fractures of children were reviewed. 1) The sex ratio was 2.1:1 (male to female). Those in their fifth decade showed the highest incidence at 26.3%, next came those in their third decade. 2) The most common cause of the trochanteric hip fractures was traffic accidents (57.9%), other cause were slipping or falling down, direct trauma and pathological fractures. 3) The ratio of left trochanteric hip fractures to right was 7:6. 4) In the group which received external immobilization with Buck's extension skin traction and delayed weight bearing method, the results were better than that group to which external immobilization was not applied and early weight bearing was allowed. 5) The group which received the external immobilization and delayed weight bearing method showed a total failure rate of 21.8% 6) The group to which external immobilization was not applied and early weight bearing was allowed a total failure rate of 64%.
