Overview
Brief Summary
This study is a comparison of sensory recovery outcomes following the use of AVANCE Nerve Graft or hollow tube conduit for peripheral nerve gap repairs in the hand.
Detailed Description
The CHANGE study is a post-marketing study designed as a prospective, single-blind, randomized, two phase study comparing clinical outcomes of AVANCE Nerve Graft to hollow tube conduits. The first phase (pilot phase) assesses projected differences expected between two treatment groups. The second phase of the study provides comparison data between the two treatment groups. AVANCE Nerve Graft is current regulated in the United States as a 361 HCT/P Tissue for transplantation; not a Drug, Biologic, or Medical Device. Hollow tube conduits are currently regulated in the United States as medical devices.

Eligibility Criteria
Inclusion Criteria
- •Require primary or secondary nerve injury repair with Hollow Nerve Conduit or AVANCE™ in at least 1 digital nerve;
- •Undergo End to End nerve to nerve graft coaptation on both the proximal and distal portion of the nerve gap in the AVANCE™ group or nerve entubulation in the Hollow Nerve Conduit group;
- •Be willing to comply with all aspects of the treatment and evaluation schedule over a 12 Month duration; and
- •Sign and date an IRB-approved written informed consent prior to initiation of any study procedures, including screening procedures.
Exclusion Criteria
- •Nerve gaps of \< 5 mm or \> 20 mm;
- •Estimated distance of regeneration of \>125 mm (distance from injury site to sensory target)
- •Nerve crush or avulsion injuries;
- •Incomplete nerve transections;
- •Injury requiring replantation of target digit;
- •Contralateral digital injuries corresponding to the target digit;
- •Nerve injuries in the affected limb proximal to the crease of the wrist;
- •End to side nerve repair;
- •Injuries with significant vascular damage which may impair adequate perfusion of the target limb;
- •Subjects who are undergoing treatment with chemotherapy, radiation therapy, or other know treatment which affects the growth of neural and/or vascular system;
