Reconstruction in cases of skin and soft tissue loss may be particularly challenging. Here we present a 79-year-old female with recurrent, previously radiated left shoulder chondrosarcoma who underwent forequarter amputation with a ‘spare parts’ filet of forearm flap and targeted muscle reinnervation to the flap. The patient healed without complication and achieved reinnervation with minimal pain. Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.
