COMPLICATIONS AFTER SURGICAL TREATMENT OF JUPITER’S MONTEGGIA TYPE II FRACTURES

Abstract

ABSTRACT Monteggia fracture-dislocations are rare injuries, affecting about 2-5% of the population. Jesse Jupiter subdivided Bado’s Type II fractures into four types, all of which presented an associated radial head fracture. Associated chondral and ligament injuries can evolve with postoperative complications. Objective: To evaluate the incidence of complications and risk factors that may influence the postoperative outcomes of Jupiter lesions. Methods: This retrospective study was conducted with surgically treated patients. The characteristics related to fractures and surgical approaches were evaluated and these variables were correlated with radiographic and functional postoperative complications. Results: A total of 15 patients were evaluated, mostly men and with a higher prevalence of Types IIA and IID. The most frequent complications were heterotopic ossification and osteolysis around the radial head prosthesis. Postoperative instability occurred only in the lateral collateral ligament. According to MEPS functional score, 53% of the patients evolved with unfavorable outcomes. Conclusion: The studied cases evolved with high rates of postoperative complications, mainly in Jupiter’s Type IID fractures and associated coronoid fractures. Level of Evidence III, Therapeutic Study.
