Apparatus and Method for Aligning a Guide Pin for Joint Re-Surfacing
First Claim
1. A drill guide for aligning a guide pin comprising:
- a base having a concave inner surface, an outer surface opposite the inner surface, and a central axis perpendicular to the inner surface;
a drilling template extending axially from the outer surface of the base along the central axis, wherein the drilling template includes a plurality of through-bores extending completely through the drilling template to the inner surface of the base;
a first curved member extending along a central longitudinal axis from a fixed end integral with the base to a free end distal the base;
a second curved member extending along a central longitudinal axis from a fixed end integral with the base to a free end distal the base;
wherein the first curved member and the second curved member are angularly spaced about 180 degrees apart relative to the central axis;
wherein each curved member includes an elongate locking slot aligned with the central longitudinal axis.

Abstract
A drill guide for aligning a guide pin. In an embodiment, the drill guide comprises a base having a concave inner surface, an outer surface, and a central axis perpendicular to the inner surface. In addition, the drill guide comprises a drilling template extending axially from the outer surface of the base along the central axis. The drilling template includes a plurality of through-bores. Further, the drill guide comprises a first curved member extending along a central longitudinal axis from a fixed end integral with the base to a free end distal the base, and a second curved member extending along a central longitudinal axis from a fixed end integral with the base to a free end distal the base. The first curved member and the second curved member are angularly spaced about 180° apart relative to the central axis and include an elongate locking slot.

21. A method of aligning a guide pin for re-surfacing a joint comprising:
-
(a) providing a drill guide comprising; a base having a curved inner surface, an outer surface opposite the inner surface, and a central axis perpendicular to the inner surface; a plurality of curved members extending from the base and angularly spaced relative to the central axis, wherein each curved member extends along a central longitudinal axis from a first end coupled to the base to a second end distal the base; a drilling template centered on the upper surface of the base, wherein the drilling template includes a plurality of through-bores; wherein each curved member includes an elongate locking slot positioned along the central longitudinal axis; (b) placing the drill guide over a ball portion of a ball and socket joint such that the inner surface of the base engages the ball portion; (c) restricting the rotation of the drill guide relative to a first axis; and (d) restricting the rotation of the drill guide relative to a second axis orthogonal to the first axis. - View Dependent Claims (22, 23, 24, 25, 26)
