Study Notes
The Hip Complex
- The hip requires mobility to perform daily and sport-specific movements, such as sit-to-stand, climbing stairs, and other functional movements.
Anatomy of the Hip
- The hip joint is a multi-axial ball and socket joint between the femoral head and the acetabulum, similar to the shoulder joint.
- The hip is surrounded by several ligaments that provide support and stability, including:
- Labrum, which attaches to the acetabulum deep within the socket between the femur and acetabulum.
- Iliofemoral or "Y" ligament, which resists extension.
- Ischiofemoral ligament, which resists extension and internal rotation.
- Pubofemoral ligament, which resists abduction.
- Muscles involved in hip function:
- Glute medius and minimus, located along the anterolateral aspect of the hip, stabilize in the frontal plane.
- Glute maximus, located in the sagittal plane posteriorly, facilitates hip extension.
Movement and Dysfunction
- The foot requires mobility to initiate movement.
- The knee requires stability for daily movements and dynamic sport movements, such as soccer or football.
