Abstract

Abstract In the treatment of sarcoma, the reconstructive surgeon must consider not only limb salvage but also functional reconstruction. The aim of this study was to evaluate a functional reconstruction of a dorsal forearm defect after sarcoma resection using immediate tendon transfer. Patients who underwent reconstruction of a dorsal forearm defect after sarcoma resection with an immediate tendon transfer between 1997 and 2019 at our hospital were included in this retrospective study. Patient demographics, tumor characteristics, surgical characteristics and functional outcomes were examined. Nine patients were included in this study. Tendon transfer of the flexor carpi radialis (FCR) or the flexor carpi ulnaris (FCU) to the extensor digitorum communis (EDC), the brachioradialis (BR) to the EDC, and the palmaris longus (PL) tendon to the extensor pollicis longus (EPL) was performed in seven, two and five patients, respectively. Seven patients underwent reconstruction using a free flap. Neither anastomosis complications nor infections were encountered. Partial flap necrosis and donor site dehiscence were seen in one case each. The mean distal interphalangeal (DIP), proximal interphalangeal (PIP) and metacarpophalangeal (MP) joint active extension were 4.4°, 6.1° and 11.1° postoperatively. The mean Musculoskeletal Tumor Society (MSTS) score was 26. Immediate tendon transfers of the FCR or the FCU to the EDC and the PL tendon to the EPL can be considered an optimal functional reconstruction of a dorsal forearm defect after sarcoma resection.
