ABSTRACT:
The proposed apparatus for joint movement restitution comprises two pairs of needles each of which is designed to be driven through one of the joint ends, one of the needles being aligned with the pivotal axis of the joint. Each pair of needles is secured in at least one brace so as to define with the brace a rigid system to be secured on the respective joint end. The two rigid systems are interconnected by distractors which are fixed to one of said systems and connected to the other system by way of ball joints whose fulcrums lie on the longitudinal axis of the needle aligned with the pivotal axis of the joint. The apparatus of the invention provides for joint movement after various angular deformation of the joint ends secured in the apparatus have been corrected.
