- A fall onto an outstretched hand classically causes a ____, a dorsally displaced fracture of the distal radius.
- Colles fracture
- What is the earliest and most reliable clinical sign of compartment syndrome?

- Which nerve is most commonly injured in an anterior shoulder dislocation?
- The axillary nerve.
- A posterior shoulder dislocation should raise suspicion for which two causes?
- Seizure or electrical shock.
- How does a patient with a displaced hip fracture typically present on exam?

- What is the classic patient profile for slipped capital femoral epiphysis (SCFE)?
