(tears are usually in this order)
Medially: Deltoid ligament (very rare to injure)
What structures can be damaged in an anterior shoulder dislocation?
- Axillary nerve and posterior circumflex artery
- Supraspinatus tendon
- Bankart Lesion (anterior dislocation)
- Hill-Sachs Lesion (traumatic injury)
A patient refers severe shoulder pain. These pains are due to severe shoulder adhesions that lock the shoulder in place; seen with disuse of the shoulder due to pain or prolonged immobilization. The patient refers restricted use of the shoulder. X-rays are normal, Arthogram shows constriction of the joint capsule and loss of axillary and subscapularis spaces. What pathology is at hand?

Traumatic lesion to the posterolateral head of the humorous due to abrasion.
Lesion to the the posterior cord (C7) results in lesion to the axillary and radial nerve, causing what clinical manifestation?

Distortions of the hand: lesion is distal ulnar nerve injury. What is the presentation and problem with the nerve?
Ulnar claw - hand his unable to extend and is always in flexion. This claw appearance.

Median claw. The thumb, 2nd, and 3rd digits and unable to extend. The fingers look flexed.
Distortions of the hand: lesion is proximal median nerve injury. What is the presentation and problem with the nerve?
