Summary
Brief summary (as posted)
The purpose of this study is to examine the effect of targeted muscle reinnervation on the outcomes of amputees at a level 1 trauma center. The investigators propose to randomize all patients requiring amputation with and without targeted muscle reinnervation. This study will help delineate the efficacy of targeted muscle reinnervation in the general population.

Arms (2)
- type
- EXPERIMENTAL
- label
- Amputation with TMR
- description
- Amputation will follow standard procedure, but with the addition of the TMR procedure, which involves rerouting severed or injured nerves to new muscle targets using microsurgical techniques to provide the nerve endings with a new muscle to innervate.
- interventionNames
- Procedure: Targeted Muscle Reinnervation
