Canine elbow repair and instrumentation

摘要

Instrumentation and assembly for arthroscopic elbow surgery which includes a humeral component. The humeral component is installed in a trough formed in the humeral condyle. The trough may be formed by using a plurality of drill pins and a plurality of corresponding cutters (and optionally a template). The two drill pins are passed through the template and drilled into the humerus, and cutters are advanced over the corresponding drill pins to form the trough. The humeral component may be employed in conjunction with an ulnar implant.

主权项

1. An elbow repair assembly, comprising:
a template configured to be aligned to a curvature of a humeral condyle and to assist in the formation of a humeral trough within the humeral condyle for an elbow repair; two drill pins with two thread guide posts, the two thread guide posts being introduced into the template to assist in the formation of the humeral trough; a retrograde cutter for removing bone from the humeral condyle to form the trough; and a humeral implant having an outer, articulating surface shaped in the form of the humeral condyle and an opposing underside surface which is substantially flat, and two projections extending from the underside surface opposite the outer, articulating surface and in a direction about perpendicular to the outer, articulating surface, for securing the humeral implant in the humeral trough formed with the template and the two drill pins with two thread guide posts, wherein each of the projections comprises a through hole for receiving at least one flexible strand, the humeral implant being pulled into the humeral trough by using the at least one flexible strand passing through the projections.
