Q

What are the normal anatomic factors that make the shoulder joint vulnerable to dislocation?

A
  1. Poor bony fit of round humeral head and shallow socket of the glenoid fossa
  2. Relatively loose joint capsule

Q

Identify the Rotator Cuff Muscles and their functions.

A
  1. supraspinatus: lateral abduction
  2. infraspinatus: external rotation
  3. teres minor: external rotation

16
Q

Where is there no muscular reinforcement of the joint capsule?

A

Inferiorly

17
Q

What anatomic relationships makes the axillary nerve vulnerable to injury in shoulder dislocation?

A

Because the axillary nerve courses anterior and inferior to the glenohumeral joint, it will be placed on traction by an anteroinferior dislocation.

Q

What is the lesion visible in this x-ray?

A

Midshaft fracture of humerus
