Implants, surgical methods and instruments for femoroacetabular impingement surgery

Abstract

Implants, surgical methods and instruments for the treatment of femoroacetabular impingement. In certain embodiments, the implant is placed or formed on the acetabulum to replicate the anatomy of the acetabulum (e.g., acetabular rim and / or lip, load-bearing surface in the acetabulum, cartilage, etc.). Embodiments of materials and instruments for mounting and / or forming such implants on the acetabulum are also provided. Embodiments of guide jigs for use in preparing the acetabulum to receive such implants are also provided.

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 402,249, filed August 26, 2010, the contents of which are incorporated herein by reference. technical field [0003] The present invention relates generally to hip surgery and more particularly to implants, surgical methods and instruments for the treatment of femoroacetabular impingement. Background technique [0004] Femoroacetabular (or FAI) is a condition of the hip joint in which the head of the femur and the acetabulum rub against each other abnormally, causing damage to the hip joint. There may be injury to the articular cartilage of the femoral head or acetabulum, or to the labial cartilage on or around the acetabular rim. FAI is increasingly recognized / as a cause of severe hip pain and disability and has been implicated as a cause of secondary osteoarthritis. [0005] The FAI can take one of two forms: cam or clamp. The difference betw...
