What is the most common type of acetabular labral tear?

• A. Posterior
• B. Lateral
• C. Medial
• D. Anterio

Answer: (D)

The most common type of acetabular labral tear is the anterior tear. This type of injury typically occurs as a result of hip joint instability, which can be caused by repetitive activities or trauma. The anterior portion of the labrum is particularly vulnerable to tears due to its anatomical location and the stresses placed on that region during movements such as running, pivoting, or deep squatting.

In terms of pathomechanics, anterior labral tears are commonly associated with conditions like femoroacetabular impingement (FAI), where abnormal contact between the femur and acetabulum can lead to labral damage. This highlights the importance of understanding the biomechanics of the hip when assessing labral tears and their implications for function and mobility.

The anterior labral tears often present with symptoms such as pain in the groin area, a catching sensation in the joint, and decreased range of motion. These characteristics contribute to the higher incidence of anterior labral tears compared to other types. Knowledge of the patterns of labral tears can assist clinicians in creating effective treatment plans and interventions tailored to the specific needs of patients experiencing hip problems.
