Forequarter Amputation: Reconstruction With Targeted Muscle Reinnervation to the Filet of Forearm Free Flap.

Forequarter amputation is a rarely indicated operation that has the potential for delayed wound healing, chronic pain, and dysfunction. 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.
