1. An anchor drill guide for use in a surgical treatment of acetabular impingement comprising:
- an elongated main body that has a distal end and has a bore formed therein that is open at the distal end, the main body having an inner edge and an outer edge;
a pointed tip portion that is at the distal end of the main body and is formed along the outer edge for stable alignment of the guide on a bone without impeding rotation of the guide, wherein the pointed tip portion terminates in a sharp tip that is configured to penetrate bone and the anchor drill guide is configured to pivot about the sharp tip;
a rounded tip portion that is formed along the inner edge of the main body at the distal end thereof for retracting the labrum into an inner recess, wherein the pointed tip portion is more distal than the rounded tip portion; and
a contoured tip portion that is joined to inner edge of the main body such that the contoured tip extends outwardly from the inner edge of the main body and distally beyond the sharp tip portion and the inner recess is defined between the main body and the contoured tip portion, the contoured tip portion for resting on cartilage.
