Description of intervention(s) / exposure
Treatment: Devices - Axoguard HA+ Nerve Protector™

Other: First Revision Cubital Tunnel with application of Axoguard HA+ Nerve Protector - Single group assignment. Patients will receive the Axoguard HA+ Nerve Protector™ in their first revision cubital tunnel surgery.


Treatment: Devices: Axoguard HA+ Nerve Protector™
Axoguard HA+ Nerve Protector™ is a surgical implant that provides non-constricting protection for non-transected peripheral nerve injuries where there is no gap. Axoguard HA+ Nerve Protector™ is designed to be an interface between the nerve and the surrounding tissue.

Summary
Brief summary
This single-cohort, prospective case series is designed to evaluate and characterize the use of Axoguard HA+ Nerve Protector™ to protect the ulnar nerve in a first revision cubital tunnel decompression procedure. Data on the primary cubital tunnel syndrome decompression, first revision decompression utilizing Axoguard HA+ Nerve Protector, participant-reported pain, motor and sensory functional outcomes, quality of life (QoL) outcomes, and recurrence/revision will be collected. This case series will help to establish the ability of Axoguard HA+ Nerve Protector to provide clinical benefits for patients undergoing a first revision cubital tunnel decompression procedure.
