Though various methods stimulating the bony fusion due to compression has been devised for osteosynthesis, the appliance for compression is needed in these methods and a hole has to he provided in the bone for its application. A new compression plate for osteosynthesis has been developed in our clinic, which needs no appliance. This plate decreases in its use the damage to the bone and soft tissues.This compression plate has its characteristics in the groove of the screw of the Scherman type. When the screw is turned in the fractured surfaces of the proximal and distal fragments draw near and are compressed.The mean weight applied to the fractured surface is 60kg per square of cross section in plate with a strain gauge, and the maximum weight 125kg.In 19 cases of femoral and tibial shaft fracture, the sign of bony fusion has been showed between 40 to 70 days in using the compression plate.
