Abstract

Special plate is suggested to provide extraosseous compression-dynamic osteosynthesis. The plate consists of two parts: base and rack. Longitudinal shift of the rack relative to the base is made by the rotation of the key which has a gear tenon on its end. The tenon and base are connected by gear transmission. Shift of the rack enables to put two bones fragments nearer and achieve their tightness and compression. Conditions for fracture healing are obtained.
