Document Summary

The pelvic girdle is made of the: The hip bone is actually 3 bones fused together: These 3 ossify together at the acetabulum this is where the femur ball and socket joint is. Sacroiliac joint between sacrum and ilium. Strong interosseous ligament limits most movement. Allows weight transfer from legs to hip to spine. Seen as the 2 ridges near top head. The patella is a sesamoid bone sitting near the bottom head. The hip joint is a ball and socket joint for the femur. Deepened by labrum good congruency between ball and socket. Reinforced by 3 strong ligaments (1 from each part of the hip bone) The bony trabeculae of the hip and femur. The trabeculae form over time and align in the way where greatest force is being exerted. For this reason, the neck of the femur tends to be less dense than the head and is thus prone to injury. This often disrupts blood supply (next lecture)
