[ 12 ], using 3D-CT, found that 38% of cases with cam also had acetabular retroversion and in 54% of cases of pincer, cam was also noted. Acetabular retroversion is a form of hip dysplasia (where the hip fails to form normally). Patients with Pincer FAI due to protrusio acetabuli or acetabular retroversion have intra-and extraarticular anterior subspine hip impingement on a 3D-CT based impingement simulation. Often, surgery for hip impingement can be performed arthroscopically.

", see section ""Bernese" Periacetabular Osteotomy". My 19 son with EDS 3 has just been told he has acetabular dysplaysia and might benefit from surgery (an acetabular osteotomy). Acetabular retroversion (AR) consists of a malorientation of the acetabulum in the sagittal plane. When the retroversion is marked, however, there is a demonstrable alteration in the pattern of hip flexion in the neutral line. Acetabular retroversion is a form of pincer morphology and predisposing factor for femoroacetabular impingement and is thought to promote osteoarthritis of the hip 3. Corrective surgery including revision PAO and THA results in improved clinical outcome. Questions/purposes The purpose of this study was to compare the acetabular morphology in terms of acetabular version and coverage of the femoral head in adolescents who sustained a posterior hip dislocation during sports and recreational activities with a control group of patients without a history … reported that all 60 had acetabular surgery, 25 rim and labrum resection, and 35 rim resection and labrum reattachment . Two to three anchors of surgeon choice (knotless vs. knotted) are used to reattach the labrum with care not to leave the knots on the intra-articular side if using knotted anchors. Symptoms of this condition which may be present from birth, but may only become evident in adolescence or adulthood generally include hip pain and restricted mobility.

Among the 68 hips, 33 had acetabular retroversion (retroversion group) and 35 had anteversion (control group) preoperatively. 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.

The … Note the intersection of lines nearly at half of its height (acetabular retroversion index of about 50%). In many cases the best option is to reorient the pelvis via an osteotomy (bone realignment procedure) to change the direction the hip joint (socket) is facing and use the existing hip joint to more appropriately cover the femoral head (ball). These bones may rub against each other during movement and cause pain.

This surgery includes cutting and realigning the femur. Acetabular retroversion Some forms of femoroacetabular impingement pincer type (see section "What is femoroacetabular impingement?") result from poor spatial position of the acetabulum and not just from excess of anterior or posterior wall.
