Ni-Ti memory alloy clamp plate for fracture of short tubular bone.
The clamp shape implant has a special memorial function. It consists of one main rod and 3 or 4 pairs of curved short arms located at both sides of the rod. Each pair of arms rolls into a circle, which can embrace 2/3 of the circumference of the fractured bone shaft, thus fixing fragmental bones at multiple points more securely without any limitation to the motion of adjacent joints. Therefore, clamp implant is especially useful for comminuted fracture of the short tubular bone, which is difficult to fix by other methods.
