Abstract
Introduction: Distal metaphyseal ulnar fractures are often found in conjunction with distal radius fractures. However, there is no consensus on optimal management. The purpose of this study was to determine whether simultaneous fixation of both distal radius and distal ulnar fractures would improve outcomes. Materials and Methods: Patients treated for distal radial fractures over a 4-year period at our trauma center were identified, and their medical records were analyzed. Twenty-three patients met the inclusion criteria for this study. All radius fractures were fixed using a volar locking plate. Fourteen ulnar fractures were treated with surgical fixation, and nine were treated conservatively. Data were collected on patient demographics, mechanism of injury, whether it was a closed or open fracture, Gustilo classification, AO/OTA classification, immobilization period, follow-up period, and type of treatment. Physical findings comprising the active range of motion and grip strength and radiological findings, including the ulnar variance compared to the healthy side and bone union, were evaluated. Clinical outcomes were assessed using the quick Disabilities of the Arm, Shoulder, and Hand scores. Results: There was no significant difference between the groups in the quick Disabilities of the Arm, Shoulder, and Hand scores, but the arc of dorsi-palmar flexion was more restricted in the operative group than in the conservative group. Other results were not significantly different between the two groups. Discussion: Fixation of distal metaphyseal ulnar fractures can be challenging, and several studies have shown the validity of conservative treatments. This supports the view that if the distal radius fracture is anatomically and rigidly fixed, distal metaphyseal ulnar fractures can be successfully managed conservatively. Conclusion: Our results did not show any merit in the simultaneous fixation of both distal radius and distal ulnar fractures. Thus, needless surgery should be avoided.
