Neurologic Deficits: following Supracondylar Frx
- See: Nerve Injury
- always consider an occult compartment syndrome before a neurpraxia;
- median nerve:
- most common neural injury is to anterior-interosseous branch;
- in type III frx, upto 50% of pts may show median nerve deficits;
- is frequently missed because of lack of sensory changes;
- may be seen injured in postero-laterally displaced supracondylar frx & is associated w/ vascular injuries;
- nerve is tethered on the medial spike of proximal fragment;
- note that a median nerve palsy may mask a pending compartment syndrome;

- The irreducible supracondylar fracture of the humerus complicated by anterior interosseous nerve palsy.
- Iatrogenic nerve injuries in the treatment of supracondylar humerus fractures: are we really just missing nerve injuries on preoperative examination?
- radial nerve;
- may be injured by anterior spike of proximal fragment of humerus w/ supracondylar frx w/ post-medial displacement;
- in type III frx, upto 25% of pts may show radial nerve deficits;

- ulnar nerve:

- Tardy ulnar nerve palsy caused by cubitus varus deformity.
- How should one treat iatrogenic ulnar injury after closed reduction and percutaneous pinning of paediatric supracondylar humeral fractures?
- Ulnar nerve lesions after osteosynthesis of a supercondylar humerus fracture during childhood. Indications for revision
- most nerve palsies resulting from supracondylar frx are neuropraxias, and therefore will resolve spontaneously;
- motor function should recover by 3 months and sensory changes should recover by 6 months;
- a mixed palsy (motor loss but no sensory loss) may have a better prognosis than a complete palsy (motor and sensory loss)
