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
