Positioning implement for shoulder prosthesis

摘要

The implement (1) has a sleeve (7) and a work head (8) for the glenoid bone (3). The work head has a pair of bosses (11) formed in the opposed ends of an elongated cavity (12) laterally defined by the grooved edges (13) of the osseous cut out and bordered by the bisectors (14) towards the interior of the cavity. The end bosses extend with respect to the edges and are adapted to engage in the corresponding holes (22) formed in the glenoid bone, when the head is forced into the latter and guides the implement during the forcing action on the edges.
