Axillary lateral view

5

Complications of shoulder dislocation

- Labral tear (cartilage surrounding glenoid)

Diagnostic modality for rotator cuff tear

MRI

14

Tests for rotator cuff inflam or impingement

- Hawkin's test: pain abducting shoulder or flexing elbow
- Neer's test: pain w/ forward arm flexion

15

How to tell bt impingement and rotator cuff tear

Rotator cuff tear: there is a pop/rip

Frozen Shoulder AKA...

Adhesive capsulitis

17

Pathophys of frozen shoulder

Inflam, loss of motion from thickening of glenohumeral capsule

Treatment for frozen shoulder

Decrease inflam (NSAIDS, steroids), improve motion (PT)
- May take 2-3 yrs to resolve
