Radial head arthroplasty: A pillar of stability in complex elbow fractures.

Abstract

Radial head (RH) arthroplasty (RHA) has emerged as a critical intervention in the management of complex elbow fractures, particularly Mason type III and IV injuries where the native RH is irreparable. Beyond its role in pain relief and joint congruity, RHA serves as a biomechanical cornerstone for restoring the lateral column and ensuring elbow stability, especially in the presence of associated ligamentous injuries or fracture-dislocations. This editorial synthesizes current evidence on RHA in Mason type III and IV RH fractures, with attention to biomechanical rationale, implant design, and complication trends. Aiming to reaffirm RHA's position as a vital tool in contemporary elbow trauma care, a simplified treatment algorithm is presented to support individualized surgical decision-making.
