Delayed rupture of flexor tendons in zone V complicated by neuritis 18 years following Galeazzi fracture-dislocation.

We report a rare case of an 84-year-old woman who presented with delayed, complete rupture of superficial (flexor digitorum superficialis) and deep flexor tendons (flexor digitorum profundus) of the third, fourth and fifth digits of the right hand in zone V of the flexor tendons. The patient, who was otherwise healthy, active and independent, incurred a closed fracture of her right wrist 18 years ago, which was treated conservatively. Current X-rays and operative findings confirmed a malunited Galeazzi fracture-dislocation with volar dislocation of the ulna from the distal radioulnar joint. She underwent surgical treatment to improve her hand function and agonising neuritis symptoms, as she was unable to use her middle, ring and little fingers and had developed severe neuritis of the ulnar nerve. Exploration and repair of the flexor tendons, nerve decompressions and Darrach procedure were performed. On follow-up, the patient showed improvement in hand function with the neuritis completely resolved.
