Abstract
Isolated radial nerve palsy (IRNP) in the newborn is a rare clinical condition that
must be distinguished from entities that are more common, such brachial plexus birth
palsy (BPBP). It should be suspected in newborns presenting with absent wrist and
digital extension but intact deltoid, biceps, and triceps function, as well as wrist
and digital flexor function. Whereas BPBP is highly variable depending on the extent
of the neurological involvement, IRNP resolves spontaneously, regardless of the severity
of the initial presentation. We herein present a case of newborn with IRNP whose initial
diagnosis was of BPBP.
