Radius Neck-to-Humerus Trochlea Transposition for Elbow Reconstruction After Resection of the Proximal Ulna: Report of 2 Cases

The structural and functional deficit created after wide excision of the proximal ulna for malignant bone tumors presents a difficult reconstructive challenge. The purpose of our report was to retrospectively review the outcome of the radius neck-to-humerus trochlea transposition after wide resection of malignant forearm tumors in 2 patients. Good function was obtained using this surgical technique. This surgical option provides a durable biologic solution to a complex reconstructive problem.
