Targeted muscle reinnervation surgery was performed on the left (nondominant) side of a 56-year-old male bilateral shoulder disarticulation-level amputee in conjunction with surgery to remove painful split thickness skin grafts. Surgery was performed approximately 9 months after the initial high-power electrical burns. The pectoralis major and minor muscles were denervated and used as recipient muscles for the brachial plexus nerves.4 This created 4 new physiologically appropriate myoelectric signals in the left pectoralis muscle (table 1). An unplanned, but fortuitous, result was that the median nerve reinnervated 2 functionally separate regions of the middle segment of the pectoralis major muscle. The hand close and wrist flexors portion of the median nerve reinnervated 1 region of the middle segment and was used to control hand closing, while the thumb abductors portion reinnervated a separate region of the middle segment and were used to control hand opening. The ulnar nerve transfer to the pectoralis minor was unsuccessful.
