Ulnar nerve paresis secondary to lunate dislocation

Ulnar nerve paresis secondary to lunate dislocation A volar dislocation of the lunate is a severe injury associated with rupture of the palmar capsule usually occurring as a triad with radial styloid and transcaphoid fractures. Associated median nerve palsy can occur due to palmar rotation of the dislocated lunate into the carpal tunnel, but ulnar nerve dysfunction is rare. We present the second reported case of ulnar nerve paresis secondary to lunate dislocation resulting from a wrist hyperextension injury. Early open reduction and screw fixation lead to rapid resolution of symptoms. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png European Journal of Plastic Surgery Springer Journals

Abstract

A volar dislocation of the lunate is a severe injury associated with rupture of the palmar capsule usually occurring as a triad with radial styloid and transcaphoid fractures. Associated median nerve palsy can occur due to palmar rotation of the dislocated lunate into the carpal tunnel, but ulnar nerve dysfunction is rare. We present the second reported case of ulnar nerve paresis secondary to lunate dislocation resulting from a wrist hyperextension injury. Early open reduction and screw fixation lead to rapid resolution of symptoms.
