Purpose: Most of the patients who have acute Monteggia fracture require surgical treatment. Open reduction and restoration of the alignment for the ulna, and early reduction of the radial head are the principles of treatment. The authors performed anatomic reduction and plate fixation of the ulna in acute Monteggia fractures and the aim of this study is to report the radiological and clinical results of the management.
Methods: Medical records and imaging data of 13 patients who had only internal fixation of the ulna in acute Monteggia fracture were reviewed retrospectively. The mean age was 38.8 years and average follow-up period was 23.9 months. We evaluated the range of motion, Mayo elbow performance score (MEPS), Disabilities of the Arm, Shoulder and Hand (DASH) score and complications at the last follow-up. Bone union and reduction of the radial head were reviewed by assessing serial radiographs during the follow-up.
Results: Bone union was obtained in all cases and radial heads were maintained their reduced position on the follow-up radiographs. The mean MEPS was 91.15 and the mean DASH score was 7.9 at the last follow-up. The mean elbow flexion was 136.5°, elbow extension was 1.2°, forearm pronation was 79°, and forearm supination was 71°. There was no specific complication during the follow-up and 3 patients had secondary surgery for plate removal by patients’’ request.
Conclusion: Anatomical reduction and secure fixation of the ulnar fracture without manipulating radial head dislocation in the acute Monteggia fracture showed satisfactory outcome in this study.
