Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Regenerative Peripheral Nerve Interface
symptomatic neuroma is excised, and the end of the peripheral nerve is implanted into a small denervated free muscle graft harvested from the patient
Regenerative Peripheral Nerve Interface (RPNI) surgery
Surgeons will perform neuroma resection and RPNI creation using a free muscle graft from the brachioradialis muscle harvested through a small separate incision
Traction Neurectomy
simple excision and traction neurectomy
Traction Neurectomy
Surgeons will perform neuroma resection and traction neurectomy,
