The library of 100 publications, spanning the use of Avance Nerve Graft and the Axoguard family of products, includes: Research from nearly 300 surgeon and clinical investigators; More than 90 independent non-sponsored papers, which highlights growing surgeon interest and acceptance of the Axogen portfolio of products; Repair of digital nerves in 37 publications and repair of mixed and motor nerves in 29 publications, with consistent results in short and long gap nerve injuries and sensory, mixed and motor nerve repairs; 18 publications in oral and maxillofacial reconstruction, a growing surgical application; and Six publications featuring data reports from the RANGER Study, with an 85% overall meaningful recovery rate across all nerve repairs in the study.
The protocol recommended by Preston and Shapiro for EDX evaluation of a suspected RNI was followed.6 NCS were performed by two operators, who were qualified physiatrists, using surface electrodes to assess sensory and motor nerves of the upper extremities.
Also, the pulsing sequences are designed to preferentially excite motor nerves rather than sensory nerves.

Previous findings of our research group show that adenosine [A.sub.2A] receptors play a pivotal role in motor nerves, favoring muscarinic [M.sub.2] inhibition by breaking [M.sub.1] receptor counteractions caused by downstream signaling involving activation of protein kinase A (PKA) and [Ca.sup.++] level in the motor nerve (Oliveira & Sa, 2005).
