Pain After Proximal Digital Amputation Prevention

Pain After Proximal Digital Amputation Prevention

Finger amputations are common and may be complicated by debilitating nerve pain. This study seeks to determine if nerve pain after digital amputation can be more effectively prevented with either of two new surgical techniques-targeted muscle reinnervation (TMR) or regenerative peripheral nerve interfaces (RPNI)-compared to standard treatment by traction neurectomy (TN).

Patients who require proximal amputations will have the opportunity to enroll in the study, will be randomized intraoperatively to receiving one of the aforementioned treatments, and will be followed at 3 and 6 month for outcome measures.

Inclusion Criteria:

• Patients requiring single finger amputations at the level of the proximal interphalangeal joint or proximal (i.e., closer to the body than this joint).
• Patients have the capacity to complete the informed consent process

Exclusion Criteria:

• Patients less than 18 years of age, prisoner, or other vulnerable population
• Patients with significant concomitant ipsilateral extremity injuries that would confound study
• Patients requiring emergent, staged (guillotine-type) amputations of any kind
