Radial Forearm Vascularized Osteomuscular Flap for Proximal Ulnar Deficiency After Revision Total Elbow Arthroplasty

This is the authors' abstract. We don't add key points for this paper.

CASE: A 61-year-old woman presented with a failed proximal ulna allograft-prosthetic composite after revision total elbow arthroplasty (TEA). The ulnar deficiency was addressed using an osteomuscular flap from the distal radius pedicled on the radial artery. At final follow-up, she had minimal pain and a flexion-extension arc of 0° to 130°. Radiographs demonstrated graft incorporation and a stable TEA construct. CONCLUSION: This demonstrates utilization of a vascularized osteomuscular flap from the radius for treatment of proximal ulnar deficiency in the setting of revision TEA. This technique offers an alternative option for the challenge of a failed TEA with ulnar bone loss.
