Recognition of the Femoroacetabular Impingement Syndrome on MDP SPECT CT

Abstract

The femoroacetabular impingement syndrome (FAI) is becoming increasingly recognized as a cause of intermittent hip or groin pain in physically active young adults (ie, 4th to 5th decades), which leads to early osteoarthritis. Repeated microtrauma from impingement of the femoral neck against the acetabulum occurs in those with predisposing hip geometries. Early diagnosis of this condition allows appropriate management, aimed at reducing the need for total hip replacement. This case demonstrates that FAI may be appreciated on SPECT CT MDP bone scanning.
