hip joint
Ball-and-socket anatomy
The hip joint is the ball-and-socket joint where the thighbone meets the pelvis, allowing the leg to move in multiple directions.
It bears most of the body's weight when standing or walking.
Hip joints commonly need replacement in older adults due to arthritis or fracture: She's recovering from hip joint surgery.
