Abstract
Abstract A spinal implant, e.g., to replace an excised disc, comprises a rigid generally horseshoe shape of biocompatible material, such as carbon-fibre reinforced plastics, having upper and lower planar faces (10, 11) converging towards the ends (12) of the horseshoe, and at least one hole (13, 14) from each planar face (10, 11) emerging in the outer curved face (15) of the horseshoe, to enable the horseshoe to be fixed by screws inserted through one or more selected holes in each plurality (13, 14) from the ends in the outer curved face (15) into respective adjacent vertebrae, with the screw heads bearing against shoulders (18), and with the space bounded by the inner curved face (17) of the horseshoe available for the insertion of bone graft or a bone graft substitute.
