Abstract

Summary: Neurofibromatosis type 1 (NF1) is an inherited multisystem disorder that affects one in 2500 to one in 5000 people. Neurofibromas are the second-most common benign peripheral nerve sheath tumors arising from Schwann cells and are associated with neurofibromatosis. Chronic pain and opioid use is elevated in patients with NF1 when neurofibromas are associated with sensory nerves. Surgical excision is the primary treatment of neurofibromas when they become large, malignant, or painful, but they are associated with high rates of recurrence. Targeted muscle reinnervation and regenerative peripheral nerve interfaces are two prophylactic surgical techniques that are used to prevent neuroma-associated residual limb and phantom pain in amputees. Both techniques stimulate physiologic regeneration of the nerve via trophic stimulus from denervated muscle. This case report describes two patients with NF1 who underwent targeted muscle reinnervation and/or regenerative peripheral nerve interfaces at the time of amputation. Despite the abnormality of the peripheral nerves involved, both patients had excellent postoperative outcomes with minimal pain. This experience advocates for the use of prophylactic nerve management techniques in neurofibromatosis patients despite baseline nerve pathology.
