Brief Summary
This is a double-blind randomised controlled trial (RCT) which compares the effectiveness of three surgical techniques for alleviating residual limb pain (RLP), neuroma pain and phantom limb pain (PLP). The three surgical treatments are Targeted Muscles Reinnervation (TMR), Regenerative Peripheral Nerve Interface (RPNI), and an active control (neuroma excision and muscle burying). Patients will be follow-up for 4 years.
Eligibility Criteria
Inclusion Criteria: * The participant must have a major limb amputation. * The participant is ≥ 18 years old at the time of consent. * The participant must be in generally good health to undergo a surgical intervention, as per the clinical investigator's opinion. * Time since the last amputation must be over a year at the time of consent. * The participant must have an average residual limb pain score equal or greater than 4 on the Numerical Rating Scale (NRS, 0-10) after the baseline period. * If the participant has been prescribed pharmacological treatments for pain, there must be no variations in dosage (steady consumption) for at least 1 month before the screening visit. * If the participant has been prescribed non-pharmacological treatments for pain, such as spinal cord stimulation, transcutaneous electrical nerve stimulation, and mirror therapy, the treatment must have ended at least 1 month before the screening visit. * The participant must have a stable prosthetic fitting for a
