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.

Conditions

  • Residual Limb Pain
  • Amputation Neuroma
  • Phantom Limb Pain
  • Pain, Neuropathic
  • Pain, Nerve

Interventions

PROCEDURE

Targeted Muscle Reinnervation (TMR)

Surgical procedure used to rewire injured proximal nerves to motor nerves directly innervating an otherwise redundant target muscle.

PROCEDURE

Regenerative Peripheral Nerve Interface (RPNI)

Surgical procedure where the the nerve is split into fascicles and wrapped in free muscle grafts.

PROCEDURE

Standard neuroma treatment, neuroma excision, and muscle burying

Surgical procedure where the neuroma is excised and the nerve stump is buried in an adjacent deep muscle.
