A 7-year-old boy presents to the emergency department after a fall on his outstretched hand (FOOSH) while playing cricket. On examination, he has severe pain and swelling over the anterior elbow with the arm held in slight flexion. Neurovascular examination reveals absent radial pulse, cold hand, and intact median nerve function. Plain radiographs show a displaced supracondylar fracture of the humerus with anterior angulation. What is the most appropriate immediate management?

Explanation

## Management of Supracondylar Fracture with Vascular Compromise ### Clinical Scenario Analysis This child has a displaced supracondylar fracture with a **"pulseless hand"** — a vascular emergency. The absent radial pulse with intact median nerve function suggests **brachial artery compression** from the fracture fragment, not complete transection. ### Key Point: **Immediate closed reduction is the priority in pulseless supracondylar fractures.** In 90% of cases, the pulse returns after reduction alone, indicating the artery was kinked or compressed, not torn. ### Why Immediate Reduction Works 1. Displaced supracondylar fractures cause the proximal fragment to angulate anteriorly 2. This angulation stretches and compresses the brachial artery 3. Gentle closed reduction realigns the fracture and relieves vascular compression 4. Restoration of flow prevents ischemic complications (Volkmann contracture, tissue necrosis) ### High-Yield: **"Pulseless but pink"** = vascular compression from angulation, NOT arterial transection. Reduce first, reassess pulse. If pulse returns → proceed with percutaneous pinning. If pulse remains absent after reduction → vascular surgery consultation. ### Clinical Pearl: Median nerve function is preserved because the nerve is not stretched as severely as the artery (artery is more anterior and vulnerable to compression). This finding supports vascular compression rather than complete arterial injury. ### Timing - **Immediate reduction** (within minutes) under GA to prevent ischemic time - Vascular reassessment post-reduction - Percutaneous pinning to stabilize the fracture - Vascular intervention only if pulse does not return after reduction [cite:Rockwood & Green's Fractures in Adults 9e Ch 9]
