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.

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%.

Together with review of literatures, authors reported a case of fatigue fracture of right 3rd metatarsal bone in an A-K amputee of lefe side, and added an amputation of contralateral lower extremity as a predisposing factor of fatigue fracture of metatarsal bone.

Synovial chondromatosis is a rare entity characterized by metaplastic cartilage formation within the synovial connective tissue and the shedding of loose bodies into the joint. Of the four cases of synovial chondromatosis, experienced by authors, three involved the knee joint and one the proxiaml phalanx of the left index finger. A huge chondroma was found in the knee joint of 2 years old boy and the other one in the proximal phalanx of the left index of 11 years old girl. Histological findings disclosed the metaplastic transformation of synovium into cartilage in all cases.

Calcaneal fractures of 82 feets in 68 patients which were treated at the Dept. of Orthopedic Surgery, St. Mary's Hospital since 1974 to 1978 were cllnically analysed, and the following results were obtained. 1. Of 68 patient 50 patients were male and 18 female. Their ages ranged from 9 to 58 years and averaged 33 years. 2. Fourteen patients had both calcaneal fractures, and the spine fractures were associated in 14 patients with calcaneal fractures. 3. Of 82 fractures 50 fractures were Rowe's type 5. Of these type 5 fracture 14 cases of tongue type were treated by axial pin flxation and favourable result were obtained. All the other types of fractures were treated conservatively. 4. After treatment, the most common complication after treatment was presistant foot pain. The commonest site of residual pain was beneath the lateral malleculus. Of 82 fractures 22 cases had this complaint. This residual pain occured in the seventeen cases type 5 fracture. 5. Residual flat foot deformity and weakness of triceps power were clinically not significant if the residual foot pain is nat associated with those two factors.

The authors reviewed 17 patients with radial nerve palsy complicating fracture of humerus who were treated at the Department of Orthopedlc Surgery, St. Mary's Hospital Catholic Medical College, for past 3 years from Jan. 1974 to Dec. 1976, and the following results were obtalned. 1. The ratio of male to female in 17 cases with radial nerve palsy was 4 to 1, and In patients within the first decade the ratio was same (1:1). But those in the 3rd and 4th decade showed high incidence of palsy. 2. Among 113 humerus shaft fractures, 17 cases (15.0%) complicated the radial nerve palsy; among 17 cases the middle shaft fractures were 15, lower 2, none in the upper third. 3. The radial nerve was the most vulnerable to injury at the middle third of the humerus, especially when there was comminution of fracture. 4. The incidence of radial nerve palsy in closed fracture (102 cases) was 13.7% (14 cases), and 27.2% (3cases) in open fracture (11 cases). 5. By early surgical exploration the practlcal cause of radial nerve palsy in 9 cases were found; 2 cases by bruise, 2 by interposition, 2 severance of nerve, one stretching, one impaled, and one unknown. 6. There were no signiflcant correlation between the type of nerve damage and the degree of its recovery, and between duration of paralysis since onset and its prognosis. 7. Of the 17 cases with palsy, complete recoveries were obtained 11 cases, 5 incomplete, and no recovery in one.
