MRI

›MRI role

›MRI performance high for full thickness tears per ACR evidence based criteria

›Use when ultrasound expertise limited

07Disposition/dispo17

Discharge vs urgent referral

›Disposition framework

›Pseudoparalysis

›ED ortho consultation or transfer

›Associated dislocation not reducible
