Nerve Injury:
- Discussion:
-
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;
-
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;
- Treatment:
- 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);
