Novel 3D-Printed Reverse Shoulder Prosthesis for Reconstruction After Resection of the Scapular: A Report of 2 Cases

Abstract

Case: The effective reconstruction and functional restoration of the shoulder joint after surgical treatment of shoulder girdle tumors, especially those involving resection of the glenoid, poses significant challenges. Reconstruction methods include allograft reconstruction and shoulder prosthesis. In this report, we present 2 cases of scapulectomy for tumors involving the glenoid, followed by shoulder reconstruction using custom-designed reverse shoulder prostheses that are partially fixed to the clavicle. Functional outcomes were satisfactory at 25 and 19 months, respectively.

Conclusion: This novel prosthesis design, which is partially fixed to the clavicle, provides stability and promising functional outcomes in scapular reconstruction with short-term follow-up.
