Guide for angularly positioning the bones of a joint in order to perform arthrodesis

Abstract

The invention provides a guide for angularly positioning bones in a joint in order to perform arthrodesis, the guide comprising: a base for positioning on the joint, and having an adjustment shaft whose position is designed to be adjusted so as to be substantially vertically above a fixed first geometrical reference point R of the joint; and an adjustment assembly mounted to slide axially and in rotation on the adjustment shaft to adjust respectively a height for the assembly relative to the first geometrical reference point R and a first angle α for the assembly about said axis, said adjustment assembly being formed by an angular adjustable member which can be positioned on a graduated piece to adjust a second angle β centered on the first geometrical reference point R, but situated in a plane different from the first angle α. The guide is suitable for metatarso-phalangeal positioning.
