Prevalence and impact of pain at the greater trochanter after open surgery for the treatment of femoro-acetabular impingement

Femoro-acetabular impingement can cause pain and degenerative changes of the hip joint. Traditionally, surgical dislocation of the hip joint has been performed for correction of pathologic abnormalities in the proximal part of the femur and the acetabulum. Failures of surgical treatment are often related to postoperative pain in the groin or in the area of the greater trochanter, associated with this surgical approach. The aim of our study was to determine the prevalence and functional impact of pain at the greater trochanter after surgical dislocation of the hip.
