In supracondylar fracture pediatrics:
- anterior interosseous nerve (AIN) neurapraxia (branch of median n.) is the most common nerve palsy seen.
- Radial nerve palsy is second most common neurapraxia (close second).
- ulnar nerve palsy is seen with flexion-type.
- Nearly all cases of neurapraxia following supracondylar humerus fractures resolve spontaneously and further diagnostic studies are not indicated in the acute setting.
- Rich collateral circulation can maintain circulation despite vascular injury.
