Pediatric Supracondylar Humerus Fracture

Gartland I–III (± IV for multidirectional instability). Complications to watch: **brachial artery injury**, **median/anterior interosseous nerve palsy**, **compartment syndrome**, **cubitus varus**. Radiographic checks: **Baumann angle**, **anterior humeral line** intersecting capitellum, and **medial comminution** (varus risk). Preferred fixation: **crossed pins** for maximal stability vs **lateral‑entry 2–3 pins** to avoid ulnar nerve injury—technique‑dependent choice. Urgent reduction/pinning for pulseless but perfused hand; vascular exploration if **pulseless and poorly perfused** after reduction.
