Impingement refers to some portion of the soft tissue around the hip socket getting pinched or compressed. Acetabular retroversion in the nondysplastic hip is one of the causes of pincer-type femoroacetabular impingent (FAI) (1,2) and has been implicated in the development of hip osteoarthrosis (OA) (3–6).The prevalence of acetabular retroversion in the normal population is 5% to 6% but this figure rises to approximately 20% in hips affected with OA (3,4). Orthopaedic Surgeon 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. How to diagnose femoroacetabular impingement? There are several different types of impingement. They differ slightly depending on what gets pinched and where the impingement occurs. Surgical Treatment As the underlying problem As the underlying problem with acetabular retroversion is All rights reserved Dr Slattery is still available for consultation during the COVID-19 pandemic.

In many cases your symptoms may respond to non-operative treatment such as activity modification, medications, injections and hip physiotherapy programs. Data protection As the underlying problemAs the underlying problem with acetabular retroversion is one of the hip joint being malpositioned, it may require correction with surgery. Having an acetabular retroversion treatment may involve either arthroscopic trimming of the bone, or osteotomy (cutting the pelvis and realigning it). In these situations, a surgical procedure known as a femoral osteotomy may be used. Both these procedures are technically complex and require careful patient selection. Acetabular retroversion can be associated with anterosuperior pincer-type impingement, posterolateral instability, labral tears, chondral damage, and posterior undercoverage. 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. In 60 cases with surgery for cam, Espinosa et al.
