What Forms the Soft Rim of Your Hip Socket?

The acetabular labrum is a fibrocartilage lip at the hip-socket rim. It deepens the socket and helps maintain a fluid seal around the femoral head, unlike the articular cartilage coating the joint surfaces.

A superior hip section contrasts a salmon rim lip with blue surface cartilage around an ivory femoral head; a closeup labels lip and fluid film.

What the illustration shows

English anatomy poster titled “What Forms the Soft Rim of Your Hip Socket?” on a deep navy background. A large superior hip section shows ivory spongy acetabular bone above a rounded femoral head. Pale blue articular cartilage covers opposing joint surfaces; a salmon triangular acetabular labrum extends from the outer socket rim. Four leader labels identify socket, labrum, cartilage and femoral head. A small pelvis locator circles the hip. A lower enlarged rim detail labels the fibrocartilage lip and a thin fluid film. Text says the rim deepens the socket, helps maintain a fluid seal, and differs from cartilage covering joint surfaces. The section is simplified and not to scale; the seal is not a rigid lock.
