Abstract

Background: The purpose of this study was to report outcomes in patients with nonstyloid distal ulna fractures treated in conjunction with open reduction internal fixation (ORIF) of distal radius fractures. Methods: A retrospective review of all patients who had undergone ORIF of a distal radius fracture over a 5-year period at a single institution was performed. Radiographic review was performed to identify patients with a concomitant fracture of the distal ulna. Radiographs were examined to determine whether and how the distal ulna fracture was stabilized and to assess healing of the distal ulna. Range of motion (ROM) was determined by review of the patients' charts. All skeletally mature patients with distal ulna fractures (not including isolated styloid fractures) undergoing surgical fixation of the distal radius fracture were included. Patients were excluded if follow-up was inadequate. There were 172 fractures of the distal ulna meeting the inclusion criteria. Seven patients were excluded. There were 91 patients treated without ulna fixation (ulna-no) and 74 patients treated with ulna fixation (ulna-yes). Results: Seventy-two (97%) of the ulna-yes patients healed. All patients in the ulna-no group healed. The only significant difference in ROM was in pronation, although the magnitude of this difference was relatively small. Conclusions: Fractures of the distal ulna have high rates of healing and result in equivalent motion regardless of whether the distal ulna is treated operatively. Routine surgical fixation of concomitant distal ulna fractures during distal radius ORIF does not appear to be necessary.
