Document Summary

The lo(cid:449)er e(cid:454)tre(cid:373)it(cid:455) is also k(cid:374)o(cid:449)(cid:374) as (cid:862)the leg(cid:863) There are 3 joints that we will consider: 1) hip, 2) knee, 3) ankle. The hip the hip is the articulation between the head of the proximal femur and the acetabulum of the pelvis the acetabulum is a deep socket that provides a great amount of bony constraint. However, the hip joint also possesses a large range of motion in all three planes: circumduction, externally, internally rotate, adduction, abduction, very strong and stable. Holding the femoral head in the acetabular socket are some large ligaments. Outside the socket is the ischiofemoral ligament on the posterior side: butt side of hip, twitst unwinds when extend and compacts when you flex loopy bit of pelvis that goes down. Articular capsule keeps hip joint water tight. In addition to the bony and ligamentous constraints, several muscles act to stabilize the femoral head within the acetabulum.
