Shoulder and hip joints

Transverse acetabular ligament

Further deepens and strengthens the acetabulum which crosses the acetabular notch on the inferior edge of the acetabulum

Shoulder joint

Glenohumeral joint; A ball-and-socket joint that has less stability, but more mobility than the other ball-and socket joint, the hip

Hip joint

Coxal joint; The femoral head articulates with the relatively deep, concave acetabulum of the hipbone to form this structure

Rotator cuff

The four muscles which holds the humeral head tightly within the glenoid cavity

Ligament of the head of the femur

Weak, flat band from the margin of the acetabular notch and the transverse ligament to a fovea in the center of the femoral head

Glenoid labrum

A fibrocartilage ring to which the joint capsule is attached

Subacrominal bursa

Located near the joint cavity but separated from the cavity by the joint capsule

Iliofemoral ligament

Strong, thick band between the anterior inferior iliac spine and the intertrochanteric line of the femur

Acetabular labrum

A lip of fibrocartilage which deepens and strengthens the acetabulum, which is incomplete inferiorly

Injury of the shoulder

Most common traumatic shoulder disorders are dislocation of bones and tears of muscles and tendons Most commonly dislocated joint in the body

Subscapular bursa

Opens into the joint cavity
