Ulnar Nerve Neuropathy after Distal Radius Fracture Malunion. Uncommon Intra-Operative Findings and a Review of the Literature

Distal radius fractures are among the most common fractures. Though associated neurologic problems are not uncommon, ulnar nerve dysfunction is a rare complication. An interesting case of sensory impairment of the ulnar nerve in a female patient with distal radius malunion, 6 months after a conservatively treated fracture, in which surgical intervention revealed an anatomic variation of ulnar nerve route, is presented in conjunction with a review of relevant literature.
