Supracondylar fractures of the humerus
A free high-yield preview for the UKMLA Applied Knowledge Test, covering how to recognise this condition. The full SA Note notes add investigations, management and complications, with practice questions on this topic.
Key high-yield points
- Typical patient: child after fall from height (playground, bicycle) - FOOSH with elbow in extension
- Severe elbow pain, rapid swelling, inability to move arm
- Visible S-shaped/bayonet deformity in severe displacement (Types III-IV)
- Neurovascular exam - check radial pulse, capillary refill, AIN (OK sign), median, radial, ulnar nerve function
A 'pink pulseless hand' (warm hand, CRT <2 s, absent radial pulse) still requires urgent joint orthopaedic and vascular surgical review - collateral circulation may maintain perfusion temporarily.
