Effect of Prophylactic TMR and RPNI on Neuroma and Phantom Limb Pain

Amputation Clinical Trial

Official title:
Prophylactic Treatment of Neuroma and Phantom Limb Pain With Targeted Muscle Reinnervation (TMR) and Regenerative Peripheral Interface (RPNI) at the Time of Major Limb Amputation: A Randomized Control Trial

Clinical Trial Summary

The purpose of this study is to analyze the efficacy of novel interventions in post-amputation surgical care (specifically Targeted Muscle Reinnervation and Regenerative Peripheral Nerve Interface) on post-amputation pain and functional outcomes at the time of amputation. These novel interventions have been shown to be successful in treating the downstream effects of amputations (pain, phantom limb pain, neuroma pain, etc.), but has not been studied in a randomized manner at the time of amputation.

Clinical Trial Description

The investigators plan a randomized control trial of all eligible patients undergoing major limb amputation at Parkland Memorial Hospital. Eligible patients undergoing an amputation will be consented for all possible interventions and randomized to either receive Targeted Muscle Re-Innervation (TMR), Regenerative Peripheral Nerve Interface (RPNI), or standard post-amputation surgical care at the time of their operation. Key pre-operative data including patient sex, age, BMI, past medical history, past surgical history, medications, allergies, social history, social support systems, exposure to narcotic medication, and reason for amputation will be analyzed. Intra-operatively, patients randomized to the treatment arm will receive TMR or RPNI and the transected nerve ends addressed will be recorded. Post-operative data that will be recorded include hospital stay, complications related to the procedure, complications leading to reoperation, functional results, need for pain medication, incidence of phantom limb pain, incidence of painful neuromas, length of follow-up, and all adverse events/complications. Analyses will be conducted using data obtained from patient medical records from the Parkland Health & Hospital System. ;
