Although ulnar neuropathy can occur at the wrist in association with distal radius fractures, few late-onset cases have been reported. The authors describe 2 cases of delayed-onset ulnar neuropathy at the wrist, which developed 12 and 30 years after sustaining a conservatively treated distal radius fracture. During late neurolysis, both patients were found to have a perforation in the volar wrist capsule and synovitis and arthritis in the distal radioulnar joint.
