Background:
Missed Monteggia lesions results in chronic luxation and deficits in the range of motion. The overall therapeutic goal is a quick and stable anatomical repositioning of the lesion. The prognosis of Monteggia lesions in comparison to its equivalents is better, especially with early diagnosis.
Objective:
Comparison of the types of lesion, treatment modalities, hospitalization, immobilization, movement deficits, perioperative complications and outcome.
Material And Methods:
Retrospective study of 62 patients treated with acute Monteggia lesions and its equivalents during the period of 2009-2020.
Results:
2 patients were treated with cast immobilization only, 11 with repositioning under general anesthesia, 39 with intramedullary nailing and 10 with screw osteosynthesis. The average observation period was 4.1 months. Patients with cast immobilization needed only a short hospitalization (2 days), patients with repositioning or osteosynthesis had longer hospitalization (3.4 or 4.3 days, respectively). Deficits of the range of motion did not appear in simple cast immobilization or intramedullary nailing without reduction; however, patients with closed reduction or screw osteosynthesis showed some degree of deficits (9% and 40%, respectively). Monteggia lesions needed shorter hospitalization than their equivalents (3.7 vs. 4.5 days) and had less deficits in the range of motion (7% vs. 21%).
Conclusion:
Most patients were treated with osteosynthesis (79%). Patients with Monteggia lesions had a better outcome than patients with equivalent lesions.
