S. Saitoh et al., Tardy ulnar tunnel syndrome caused by Galeazzi fracture-dislocation: A neuropathy with a new pathomechanism, J ORTHOP TR, 14(1), 2000, pp. 66-70
We present a case of late-onset ulnar tunnel syndrome following a Colles fr
acture. The nerve palsy was caused by a vascular branch that stretched over
the ulnar head, compressing the nerve and generating friction against the
ulnar head when the forearm was rotated. This is the first report of such a
pathomechanism.
