1 Hip Joint

2 The hip is the most proximal of the lower extremity joints. It is very important in weight- bearing and walking activities. Like the shoulder, it is a ball-and-socket joint. The rounded or convex-shaped femoral head fits into and articulates with the concave-shaped acetabulum. Unlike the shoulder, the hip is a very stable joint and therefore sacrifices some range of motion. The hip joint (a triaxial joint) has motions in all three planes.
