Study Notes
Hip Joint Anatomy
- The teres ligament in the hip joint strengthens the joint capsule and helps to stabilize the femoral head.
Labrum Function
- The labrum, a fibrocartilaginous ring, deepens the acetabulum, allowing for greater articulation and increasing the range of motion.
Acetabular Fossa
- The acetabular fossa is divided into a central non-articular region and a peripheral articular region.
Hip Joint Mobility
- The hip joint has 3 degrees of freedom, allowing for flexion, extension, abduction, adduction, rotation, and circumduction.
Congruency in Hip Joint
- The head of the hip joint maintains congruency with the acetabulum.
Transverse Acetabular Ligament
- The transverse acetabular ligament completes the acetabular rim, converting the acetabular notch into a foramen.
Hip Joint Structure
- The acetabular labrum is described as 'horseshoe-like' in shape.
Weight Bearing Effects
- As weight bearing occurs, the acetabulum is compressed, increasing the stability of the hip joint.
