Talar bone plate

A surgical method for use of a talar bone plate with a multi-component ankle prosthesis comprising:

• providing a talar bone plate having a body including a medial side, a lateral side, an upper surface, a lower surface, a medial-anterior end, a lateral-anterior end, a medial-anterior portion that extends out in an anterior direction beyond the lateral-anterior end, and a posterior side with a length between the medial-anterior end and the posterior side of the body being greater than the length between the lateral-anterior end and the posterior side, and further with the body having at least one elongated screw hole located at a posterior end, the body defining an elongated sloped surface that slopes downwardly from the upper surface at the medial-anterior end toward the lower surface and the elongated screw hole provided in the medial-anterior portion and a plurality of screw holes provided in the area between the at least one elongated screw hole and the posterior side;
• creating an incision in a patient in proximity of the patient's ankle;
• exposing the multi-component ankle prosthesis implanted in the patient;
• disassembling at least one component of the multi-component ankle prosthesis;
• affixing the talar bone plate to the patient's talus using screws;
• and
• affixing the medial-anterior portion of the talar bone plate to the patient's navicular bone using a screw inserted through the at least one elongated screw hole such that the engagement of the screw with the elongated sloped surface applies a force to the talar bone plate that enhances the compression function of the at least one elongated screw hole.
