Radial Head Arthroplasty Through a Posterior Elbow Approach in Monteggia Type IID Fracture-Dislocation: A Case Report.

Monteggia fracture-dislocation is an inherently unstable injury in the elbow region, characterized by a fracture of the proximal ulna associated with dislocation of the radial head, often with high rates of postoperative complications. Some variants of this injury involve a combination with a fracture of the radial head, which further complicates the scenario, often requiring multiple surgical approaches, increasing soft tissue damage, and promoting a higher risk of complications. The objective of this study is to report the case of a patient undergoing surgical intervention through a posterior approach to the elbow, during which radial head arthroplasty and ulna osteosynthesis were performed. Ambulatory follow-up revealed, through the excellent early functional outcome presented, that minimizing damage through treatment with a single approach provides significant benefits.
