for motor and sensory nerve repair
allograft is a new standard of care

from efficacy to economics:
examining a new standard of care

Data continues to confirm allograft nerve repair efficacy and economics are comparable to autograft for motor and sensory nerves across gaps up to 70 mm.


allograft outcomes are comparable to autograft1


1,550+ nerve repairs across 35 studies

Meta-analysis examining the most comprehensive clinical evidence to date

key takeaway

Allograft demonstrates comparable outcomes to autograft in both mixed-motor and sensory nerve gap repair

more findings

No significant differences between allograft and autograft, holding true across:
• Motor and sensory
• >5 to ≤30 mm gaps
• 30 to ≤70 mm gaps

allograft: a cost-comparable alternative to autograft2


1,360+ peripheral nerve graft repairs

Cross-sectional study of procedure costs for allograft and autograft repairs

key takeaway

Allograft and autograft procedure costs are not statistically different

  • Inpatient: $24,733 for allograft, $23,694 for autograft
  • Outpatient: $9,874 for allograft, $9,621 for autograft

more findings

Allograft nerve repair saves OR time compared to autograft

  • Inpatient: Saves 13.7 minutes
  • Outpatient: Saves 40.5 minutes

… allograft nerve reconstruction is an effective and cost comparable treatment to autograft nerve reconstruction that avoids the burden, risk and long-term complications from harvesting a healthy nerve.”

— Joseph F. Styron, MD, PhD

allograft eliminates the risk of complications at a second surgical site
The probability of autograft donor site complication is high with symptoms like chronic pain (25.6%), functional impairment (10%), cold sensitivity (22.2%), sensory loss (87.2%).3


motor recovery in action

When compared to autograft, allograft is established as a suitable and often preferred method of nerve reconstruction with comparable outcomes.*1


autograft nerve repair costs more than just extra OR time

Autograft nerve repair for gaps less than 70 mm requires an additional surgical procedure for the patient and brings the risk of secondary site comorbidities that can disrupt patients’ quality of life long after surgery.

secondary site comorbidities3

Patients who received an autograft nerve repair required a secondary site incision, leading to:

  • 87.2% sensory loss
  • 25.6% rate of pain
  • 22.2% cold sensitivity
  • 10.0% functional impairment


Allograft nerve repair does not require an additional procedure, which decreases the time spent in the OR and cuts down on overall costs.2 Avance® Nerve Graft is the only off-the-shelf biologically active processed human nerve allograft available in a variety of lengths and diameters for intraoperative versatility.

dalton’s story

The autograft did have chronic implications for my quality of life that maybe an allograft wouldn’t have. There wasn’t an allograft option presented at all [to me].”

Proprietary testing to ensure identity, purity and safety.

This study takes the established fact that allograft is a suitable and often preferred method of nerve reconstruction and expands upon its desirability by showing it is also a cost neutral alternative to autograft. Despite having a higher implant cost, the study shows that allograft nerve repairs have statistically comparable procedure costs due to the offset of OR, room and board and other direct costs associated with an autograft nerve harvest and a secondary surgical site.
