Radial nerve palsy caused by spontaneously occurring nerve torsion

Case report

Restricted access

✓ An 18-year-old man presented with a spontaneously occurring radial nerve palsy that spared the triceps muscle. At surgery, the portion of the radial nerve located at the midarm level had an hourglass-like appearance. Under magnification, an external—internal neurolysis of the narrowed portion of the hourglass-shaped portion revealed nerve torsion. Straightening of the twisted nerve and fixation accomplished using epiperineurium—fascia stitches to avoid a new torsion resulted in complete functional recovery of the radial nerve.
