EPIDEMIOLOGY AND TREATMENT OF MONTEGGIA LESION IN ADULTS: SERIES OF 44 CASES.

OBJECTIVE: To analyze the epidemiology, treatment and outcome of a series of adult patients with Monteggia lesion treated in Uruguayan institutions.

METHODS: This is a retrospective article, we retrospectively identified from two Uruguayan institutions 44 adult patients with Monteggia lesion and analyzed their characteristics including Bado classification, associated injuries, treatment modality and outcome (Morrey score).

RESULTS: Using Bado classification, 23 cases (52%) were type II, 12 (27%) type I, seven (16%) type IV and two cases (5%) type III. Associated lesions were radial head fractures, found in 15 patients, coronoid ipsilateral fractures in seven patients, and neurological injuries in four. Radial head dislocation was reduced in 93% of the cases with closed maneuvers. Ulna fractures underwent open reduction and internal fixation in all 30 cases using 3.5 mm DCP plates. Complications after surgery occurred in 21 cases. Revision surgery was done in 15 cases. Outcomes after primary and revision surgery were good or excellent in 37 cases.

CONCLUSIONS: In our series we observed that Monteggia lesion in adults is a serious injury with a high number of complications that often require revision surgeries. Level of Evidence IV, Retrospective Study, Case Series.
