Arthroscopic Treatment of Pincer Type Impingement of the Hip

The concepts of hip arthroscopy and femoroacetabular impingement both date back to the 1930s, although their clinical association in hip-preservation surgery took decades to emerge. As the technique has evolved to allow better maneuverability and tissue management, the indications for hip arthroscopy have expanded to include a variety of hip abnormalities. The two patterns of femoroacetabular impingement are cam impingement and pincer impingement, although the majority of patients present with a combination of both deformities. Cam impingement is the result of asphericity and/or loss of offset of the femoral head-neck junction. Pincer impingement is characterized by focal or global acetabular retroversion or global overcoverage. Both types of impingement cause damage to the acetabular labrum and chondrolabral junction. With improvement of minimally invasive surgical techniques and our understanding of femoroacetabular impingement as a source of pre-arthritic hip pain, arthroscopy has become a successful and frequently utilized treatment for femoroacetabular impingement. The prevalence of hip arthroscopy has grown over the past decade, with a 365% increase between 2004 and 2009. This review will address the arthroscopic techniques that are currently used to treat abnormalities of the central compartment, with a focus on focal pincer-type impingement and acetabular labral tears.
