title: Ulnar nerve palsy following fractures of the distal radius: clinical and anatomical studies.
abstract: We report three cases of progressive ulnar nerve palsy following fractures of the distal radius. One was an open injury and one involved dorsal displacement of the nerve through a dislocated distal radio-ulnar joint. All were associated with dense scar tissue formation around the nerve. Early surgical decompression was successful in all cases. An anatomical study indicated that the relative immunity of the nerve to injury in this region may be due to its greater excursion and mobility compared with the median nerve.
