Verified step by step guidance

Understand the anatomy of the hip joint: The hip joint is a ball-and-socket joint formed by the articulation of the femoral head (ball) and the acetabulum (socket) of the pelvis. Stability is crucial for weight-bearing and movement.

Analyze the role of the acetabular labrum: The acetabular labrum is a ring of fibrocartilage that surrounds the acetabulum. It deepens the socket, increases the surface area for contact, and enhances the stability of the joint by preventing dislocation.

Evaluate the articular cartilage of the femoral head: Articular cartilage covers the femoral head and acetabulum, providing a smooth surface for movement and reducing friction. While it aids in joint function, it does not significantly contribute to stability.

Consider the synovial membrane: The synovial membrane lines the joint capsule and produces synovial fluid for lubrication. Its primary role is to reduce friction and nourish the cartilage, not to stabilize the joint.

Assess the ligamentum teres: The ligamentum teres connects the femoral head to the acetabulum and carries a small artery to the femoral head. While it has a minor stabilizing role, it is not the primary contributor to hip joint stability compared to the acetabular labrum.
