研究概览
简要总结
This study is a registry of general use of Avance Nerve Graft and is intended to evaluate the uses, response rates, and safety of Avance Nerve Graft in the real-life clinical setting. Optional addendums 1 and 2 included in the protocol are intended to establish comparative groups and focused subgroups within the registry.
详细描述
This is a multicenter registry study to collect utilization, safety, and outcomes data from medical record chart review of nerve reconstruction procedures throughout the body with Avance® Nerve Graft.
Addendum 1 (MATCH) establishes a comparative arm to collect data on nerve injuries repaired with nerve autografts and nerve tube conduits at select RANGER® participating sites.
Addendum 2 (Sensation-NOW) establishes a focused arm to collect data on autologous breast reconstructive procedures where neurotization was completed. Post-mastectomy autologous breast reconstruction procedures without neurotization will serve as an internal control group to allow for comparisons.

- •Addendum 1 (MATCH) Criteria:
- •Inclusion Criteria:
- •Have nerve transection injuries to the upper extremity;
- •Have undergone tension free end to end nerve coaptation on both the proximal and distal portion of the nerve gap with nerve autograft or nerve entubulation with nerve tube conduit at a participating ANG-CP-005 registry site after 2004 and;
- •Have completed sufficient follow-up assessments at a regeneration rate of 2mm/day to determine the outcomes of the repair or is willing to comply with site specific post-operative care procedures and assessments to determine the outcome of the repair.
- •Exclusion Criteria:
