Ulnar Nerve Palsy with Dislocation of the Nerve around the Ulna Following a Fracture of the Distal Radius
Ulnar nerve injury is a rare complication following fracture of the
distal radius. Dislocation of the nerve due to additional disruption of
the distal radio-ulnar joint (DRUJ) occurs even less frequently with
only a number of cases reported in the literature.
In this article we present a unique case of dislocation of the ulnar
nerve following distal radius fracture with dislocation of the ulnar
nerve through the DRUJ and rotation around the ulna. Surgical
repositioning of the ulnar nerve in this case resulted in nearly
complete recovery of nerve function.
In addition to its rareness, this case shows the importance of
careful neurologic examination in distal radius fractures and the
need for early explorative surgery or advanced imaging in cases
with combined DRUJ dislocation and suspected ulnar nerve injury.
