Description of intervention(s) / exposure
Surgical Repair of Peripheral Nerve Injury with CelGro "Registered Trademark" Collagen Scaffold:
CelGro "Registered Trademark is a next-generation porcine collagen membrane manufactured in Australia from locally-produced source material. It is classified as a Class III Medical Device and is intended for use in surgical applications such as tendon and soft tissue repair and guided tissue regeneration.
This is an open label pilot study where adult patients who have a traumatic injury to one or more of the peripheral nerves of the upper limb or hand that requires surgical repair will receive a single surgical implantation of CelGro "Registered Trademark at the site of the nerve end repair to be used as a conduit for nerve repair. The implantation will be performed by an Orthopaedic surgeon. The length of surgery time and recovery will depend on the number of nerves damaged and the size of the nerve gap.

Haemostasis of the nerve ends will be achieved prior to placement of CelGro"Registered Trademark". Tensionless repair will be achieved using atraumatic sutures to secure the CelGro"Registered Trademark" scaffold to the epineurium of each nerve end, resulting in a tube of CelGro"Registered Trademark" connecting and encasing the nerve ends. The site of CelGro"Registered Trademark" attachment to each nerve end will be a distance approximately greater than or equal to the nerve diameter. Fibrin glue may be used to assist with adhesion. The size of the CelGro"Registered Trademark" scaffold used will depend on the size of the nerve gap.
CelGro"Registered Trademark" is a classified as a medical device and is delivered in a sterile sealed pouch and presents as a white to off white sheet with a smooth and a slightly rough side and is intended for single use only.
