Common Injuries and Treatments
The hip joint is a very stable "ball and socket" joint. The "ball" is the top end of the femur (thigh bone). The "socket" (acetabulum) is an area on the bottom of the pelvis on each side.
Motion in the hip occurs in 3 opposing directions:
- Forward and backward (flexion and extension)
- Out to the side (abduction) and inward (adduction)
- Rotation in and out (internal and external rotation).
