Study Comparing Avance Nerve Graft and Autograft for Functional Recovery Following Mixed and Motor Peripheral Nerve Reconstruction

This is a multicenter, 1:1 randomized, prospective, evaluator blinded, comparative study in participants requiring reconstruction of a mixed or motor nerve in the upper extremity. The study will assess recovery of motor and sensory function via MRCC score for nerve repairs with Avance Nerve Graft (Study Treatment) and sural nerve autograft (Comparator) through non-inferiority analyses. Participants will be considered enrolled to the study once all screening and eligibility criteria have been met and the participant has been centrally randomized to either Avance Nerve Graft or sural nerve autograft; Inclusion and exclusion criteria are defined at decision points for pre-operative screening eligibility and operative eligibility. This study will consist of a screening visit, an operative visit, and 9 post-operative follow-up visits at Week 4, and Months 3, 6, 9, 12, 15, 18, 21, and 24.
