Amputation through the epiphyseal plate is very rare. Authors experienced only one case of ankle amputation through the epiphyseal plate in one huadred seventeen replantation cases during last seven years. It can make severe growth disturbance after replantation especially if the bone shortening is carried out at epiphyseal plate. Authors have developed new idea to make boae shortening during replantation with preservation of the epiphyseal plate in amputation through the epiphyseal plate in three years old female. It is, so called, double osteotomy shortening. Bone shortening is performed at 5cm above amputated epipyaeal plate to avoid further damage in epiphyseal plate, and a bone segment 3cm in length is resected,by double osteotomy shortening technique. After then, bone reduction and internal fixation is followed. With above technique, authors succeeded in replantation without further damage in epiphysis. In three years and ten months follow-up, bony growth in replanted tibia shows normal pattern, and epiphyseal plate in replanted site is working and remained open. The patient can walk without pain, and motor-sensory function have almost completely recoverered.

Great efforts have been expended to compensate for nerve gap in the repair of a peripheral nerve injury. And yet, this nerve gap presents a great problem in surgical management. End-to-end anastomosis is most frequently used for repair of peripheral nerves, but the main problem is tension at the suture site. The purpose of this experiment is to observe the relationship between the tension and the nerve healing, when stretching is applied to the suture site of the peripheral nerve trunk. We used 25 rabbits of both sexes divided into 5 groups according to the nerve gap and the period of immobilization for this study. Gross and histological examination were used to compare the results of end-to-end suture under a tension and suture without tension. We concluded that: 1. The best results were obtained when end-to-end suture was done without tension. 2. Direct suture under a tension produced the results quite inferior to that of the suture without tension. 3. Better results were obtained from the group of immobilization, at least, for 4 weeks among the tension group. 4. Immobilization period may be prolonged according to the degree of the tension affecting the suture site. 5. Tension at the suture site causes proliferation of connective tissue.
