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.

入选标准

  • Primary Study Criteria (RANGER Avance):
  • Inclusion Criteria:
  • Males and Females who have undergone nerve repair using the Avance® Nerve Graft for the repair of a nerve injury
  • Returned for at least one post-operative follow-up visit

排除标准

  • Subject who in the opinion of the investigator, have not or likely will not complete at least some portion of the investigator's recommended follow-up.
  • 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:
  • Direct nerve repairs;
  • Nerve gaps greater than 70mm;
  • Subjects who, in the opinion of the investigator, were non-compliant to the investigator's post-operative treatment or rehabilitation instructions;
  • Any subject who at the discretion of the Investigator is not suitable for inclusion in the study.
  • Addendum 2 (Sensation-NOW) Criteria:
  • Inclusion Criteria:
  • Female ≥ 18 years old
  • Undergo post mastectomy autologous breast reconstruction with one type of autologous flap (no stacked reconstructions or use of implant with autologous flap)
  • Neurotization must be completed using a donor nerve from the flap and a recipient nerve from the chest
  • Complete Sensory Assessment Testing with Semmes Weinstein Monofilaments (SWMF) and the following Breast-Q Questionnaires 60 - 120 days post-reconstruction:
  • Breast-Q Physical Well Being of the Chest
  • Breast-Q Satisfaction with Breast
  • Breast-Q Physical Well Being of the Abdomen
  • Breast-Q Abnormal Breast Sensations
  • Breast-Q Impact of Breast Sensation on Quality of Life
  • Breast-Q Return of Breast Sensation
  • Able to provide informed consent and are willing to comply with post-operative care procedures and assessments
  • Exclusion Criteria:
  • Surgical history of secondary revision surgery for partial or total flap loss
  • Bilateral reconstruction with non-uniform treatment (i.e. 1 reconstructed breast is non-neurotized, 1 reconstructed breast is neurotized)
  • Currently prescribed medication known to impact nerve regeneration or to cause peripheral neuropathy
  • Currently undergoing IV chemotherapy or radiation
  • Any subject who at the discretion of the Investigator is not suitable for inclusion in the study or is unlikely to comply with follow-up schedule
  • Additional Eligibility criteria to Modules
  • Module 1: Native Skin Reconstructions with and without neurotization.
  • Buried flap reconstructions from nipple sparing mastectomy or skin sparing mastectomy OR a breast reconstruction from a skin sparing mastectomy with exposed flap skin in the peri-areolar region.
  • Sensory assessments must be completed on ≥ 8 Zones of Native Skin.
  • Center zone measurement may be on either Native Skin or Flap Skin.
  • All Inner and Outer zone measurements must be on Native Skin.
  • De-identified photo of the breast reconstruction with 9 zones identified.

结局指标

主要结局

Avance Nerve Graft: Incidence of Avance Nerve Graft Related Adverse Events

时间窗: Through study completion or until lost to follow-up, approximately 3 years

Participants will be followed through the course of their recovery based on Physician's standard of care practice or until lost to follow-up.

RANGER and MATCH: Motor Function as measured by Medical Research Council Classification (MRCC) for motor recovery

时间窗: Through study completion or until lost to follow-up, approximately 3 years

Participants will be followed for a change in motor function, if applicable, to the reconstructed peripheral nerve through the course of their follow-up using Physician's standard of care motor assessments or until lost to follow-up.
