There are several different types of impingement. Global acetabular retroversion is a morphological variation involving posterior tilt of the acetabular opening, resulting in loss of the normal 17° ± 6° of anteversion of the acetabulum. First, the socket, also called the acetabulum, may develop abnormally as a child grows. femoral anteversion (i.e., femoral retroversion). The lines which mark its anterior and posterior limit (walls) intersect and the line that marks its posterior limit is located medial to the geometric center of the joint (posterior wall sign). [ 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. Surgical Treatment As the underlying problem As the underlying problem with acetabular retroversion is 17). Note the intersection of lines nearly at half of its height (acetabular retroversion index of about 50%). Background: Retroversion of the acetabulum is a cause of pincer impingement. "There are many factors to consider, involving the degree of correction and amount of arthroscopy work that may be needed," says Bruce A. However, these procedures are technically challenging and associated with high complication rates. result from poor spatial position of the acetabulum and not just from excess of anterior or posterior wall. Of all the available reconstructive osteotomies, the Bernese periacetabular osteotomy, developed by Ganz et al 11 in the early 1980s, currently is the acetabular procedure preferred by many centers for several reasons (Fig 2). 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.

Orthopedic surgeons can then collaborate to determine the most beneficial treatment plan for each individual patient. An excessive femoral retroversion can place stress on hip and knee joints, often leading to joint pain and abnormal wear. Surgical treatment of femoroacetabular impingement focuses on improving the clearance for hip motion and alleviation of femoral abutment against the acetabular rim. 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. Acetabular retroversion (AR) consists of a malorientation of the acetabulum in the sagittal plane. Radiographic evaluations of acetabular retroversion and posterior wall deficiency were based on the cross-over sign and posterior wall sign, respectively.

The aim of our study was to determine if patients with femoral retroversion have equivalent outcomes after surgical hip dislocation for Femoral Acetabular Impingement (FAI) as compared to those with normal femoral version. The optimal surgical management of patients presenting with symptomatic acetabular retroversion remains unknown. It is a common cause of hip pain and discomfort in young and middle-aged adults. BACKGROUND: Acetabular retroversion is a rotatory abnormality of the entire hemipelvis that includes anterior over-coverage and posterior deficiency of the acetabulum, and is associated with pincer-type femoroacetabular impingement and posterior hip instability. Corrective surgery including revision PAO and THA results in improved clinical outcome. They differ slightly depending on what gets pinched and where the impingement occurs. Femoroacetabular impingement (FAI) occurs in the hip joint. This includes basically the surgical resection of the impinging cause, by trimming the acetabular rim or the femoral headneck offset either via a surgical hip dislocation [3, 12, 54] or arthroscopically [55], or, rarely, by the reorientation of a retroverted acetabulum via a reversed periacetabular osteotomy [28]. Legal notice In many cases the best option is to reorient, direction the hip joint (socket) is facing and use the existing hip joint to more appropriately cover the femoral head (ball), If you are suffering from hip pain, and consider that you may have acetabular retroversion, please contact Dr Slattery’s Melbourne rooms to schedule an, appointment to talk about femoral retroversion, Unicompartmental (Partial) Knee Replacement, Rural, Interstate, and International Patients + Telehealth.
