An acetabular labrum tear or hip labrum tear is a common injury of the acetabular labrum resulting from a number of causes including running, hip dislocation, and deterioration with ageing. Most are thought to result from a gradual tear due to repetitive microtrauma .
The goal of the arthroscopic treatment of pincer impingement is to reduce the acetabular over coverage of the hip. Methods to reduce this over coverage of the ball by the socket include labral detachment or peel back, acetabular rim trimming using burrs, often reattaching the labrum with anchors at the end of the procedure.
Elementary fracture Description Associated fractures Description Posterior wall: This is the most common variety of acetabular fracture. It typically occurs due to dashboard injury; when a person travelling in a vehicle involved in a head-on collision, the force applied over the flexed knee travels along the femur bone to the head of the femur, breaking the posterior wall of the acetabulum.
In radiography the presence of a "crossover sign" is produced when the posterior wall of the acetabulum crosses the anterior wall before reaching the acetabular roof. It is a sign of acetabular retroversion and it has been linked with overcoverage and pincer impingement. Nevertheless, this sign has been described in 6% of the normal population.
The most severe degrees of labral pathology is often unresponsive to labral repair, with damage far too diffuse for focal debridement. In these cases, labral reconstruction is the best option for not only restoring the biomechanics of the acetabular labrum, but for treatment of the patient's pain.

The acetabular labrum (glenoidal labrum of the hip joint or cotyloid ligament in older texts) is a fibrocartilaginous ring [1] [2] [3] which surrounds the circumference of the acetabulum of the hip, deepening the acetabulum. The labrum is attached onto the bony rim and transverse acetabular ligament. It is triangular in cross-section (with the ...
The dedicated medical staff at a Duquesne women's basketball game sprang into action last month to save Ed Wesolowski, a father of three, after he suffered a widow-maker heart attack and collapsed ...
Protrusio acetabuli is an uncommon defect of the acetabulum, the socket that receives the femoral head to make the hip joint. The hip bone of the pelvic bone/girdle is composed of three bones, the ilium, the ischium and the pubis. In protrusio deformity, there is medial displacement of the femoral head in that the medial aspect of the femoral ...
