Single-bone Forearm Reconstruction for Malignant and Aggressive Tumors

Abstract

Limb-salvage surgery for malignant and aggressive forearm tumors presents a unique surgical challenge. We performed single-bone forearm reconstructions after extensive resections of the radius and ulna in four patients for such tumors. Radiocarpal arthrodesis was performed in three patients. We recorded the presence of metastases or local recurrences, Musculoskeletal Tumor Society upper extremity scores, and complications. One patient had local recurrence and one died of metastases. The average Musculoskeletal Tumor Society score at the last followup was 26 of 30 (88%; range, 24-28). Complications included wound infection/necrosis, delayed union, nonunion, and acute carpal tunnel syndrome. Single-bone forearm reconstructive surgery provided satisfactory functional outcomes in these four patients, and we believe it is a reasonable treatment option for individuals with malignant or aggressive tumors of the forearm requiring massive bone resection. Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.
