WebNov 24, 2024 · It’s usually due to one of three main causes. First, the socket, also called the acetabulum, may develop abnormally as a child grows. This can lead to a condition known as acetabular retroversion, in which the socket grows too far over the front of the ball, or femoral head, of the hip joint. WebAcetabular retroversion is a condition where the hip socket (acetabulum) faces backwards (retroversion) rather than forwards (anteversion). The position and direction of the hip joint is critical in determining a safe, and painfree hip range of motion. In the normal hip, the acetabulum (cup/socket) normally points forward approximately 20 degrees.
