Elbow interposition arthroplasty in a young adult: A case report.

Introduction: Posttraumatic elbow arthritis in young adults is a rare yet challenging condition, presenting primarily with progressive pain and stiffness that limits functional activities. Achieving a functional, low-pain elbow joint with future treatment options is essential for younger, active patients. Unlike total elbow arthroplasty (TEA), which is prone to loosening in young patients, interposition arthroplasty (IA) offers bone preservation, pain reduction, and improved joint function.
