What is acetabular Overcoverage?

What is acetabular Overcoverage?

Abstract. Introduction: Acetabular overcoverage promotes hip osteoarthritis causing a pincer-type femoroacetabular impingement. Acetabular coverage in the horizontal plane is usually poorly defined in imaging studies and may be misdiagnosed.

What is acetabular Osteoplasty?

Osteoplasty involves the use of a motorized burr to trim the excess bone at the femur neck. Acetabular rim trimming involves the use of a motorized burr to trim the acetabular rim. The amount of bone removed during this procedure depends on the presence and type of impingement.

How is acetabular Retroversion treated?

As 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).

How do you fix femoral acetabular impingement?

Femoroacetabular impingement (FAI), also called hip impingement, is a condition where the hip joint is not shaped normally. This causes the bones to painfully rub together. This condition can be treated with corticosteroids, nonsteroidal anti-inflammatory drugs (NSAIDs), physical therapy, rest and surgery.

Do you need surgery for hip impingement?

Patients diagnosed with hip impingement syndrome can preserve their hip joint through a combination of nonsurgical and surgical treatment methods. Surgery is often recommended if nonsurgical methods have failed to reduce symptoms.

What causes pincer impingement?

Pincer impingement occurs when the acetabulum is excessively deep or covers too much of the femoral head. In the case of the latter, it often results from excess bone growth that extends out over the normal rim. The overhang can impinge the neck of the femur and tear labrum.

What is the recovery time for arthroscopic hip surgery?

You will probably need about 6 weeks to recover. If your doctor repaired damaged tissue, recovery will take longer. You may have to limit your activity until your hip strength and movement are back to normal. You may also be in a physical rehabilitation (rehab) program.

How is Osteoplasty done?

Is acetabular Retroversion painful?

However, some patients may develop symptoms due to the femur (thighbone) abnormally hitting the pelvis, or instability from the femoral head slipping backwards out of the hip joint. Common symptoms include: Hip Pain.

Is acetabular Retroversion rare?

Conclusion: Early after diagnosis, the prevalence of acetabular retroversion in our skeletally immature children with LCPD was extremely rare (1.8%), and there was no significant difference in version between the normal hips and hips with LCPD.

Can hip impingement go away on its own?

Patients diagnosed with hip impingement syndrome can preserve their hip joint through a combination of nonsurgical and surgical treatment methods. Surgery is often recommended if nonsurgical methods have failed to reduce symptoms. The key, however, is early intervention.

Does xray show hip impingement?

The diagnosis of hip impingement can be made with a physical exam and X-rays. Often, the X-rays will show the imperfections in bone structure that can cause impingement. A torn labrum cannot be seen on X-ray, but an MRI can show a tear.

What are the types of acetabular overcoverage?

–Coxa profunda –Protrusio •Focal acetabular overcoverage –Anteriorly: acetabular retroversion –Posteriorly: prominent posterior wall vs deficient posterior wall Coxa profunda: medial wall of acetabulum projects medial to the ilioischial line, femoral head remains lateral to it.

What is the difference between anterior and posterior acetabular retroversion?

–Normal acetabulum is anteverted •Anterior Rim projects medial to posterior wall line. •Cranial Acetabular Retroversion the anterior rim line becomes lateral to the posterior rim in the cranial part of the acetabulum and crosses medial in the inferior part making a figure 8 or crossover sign.

What is the pathophysiology of OS acetabulum fracture?

This os acetabulum is an acetabular rim fracture, presumed to be a stress or impingement fracture, resulting from a constant jamming of the femoral head against the acetabulum [ 27] (Fig. 16A, 16B ).

How is the original acetabular rim identified in hip fractures?

Through careful evaluation of the radiographs, the original acetabular rim can be identified. Occasionally, on the femoral side at the head–neck junction, a linear indentation may be observed in hips with pincer impingement and a cortical thickening (Fig. 17A, 17B ).
