Description of intervention(s) / exposure
The exposure being observed is the use of Remplir collagen membrane in peripheral nerve surgery.

The observation period will be dependent on the specific indication/intention of the surgical procedure and associated length of time required to assess the success of the procedure:
- Peripheral nerve protection (e.g. during treatment of compression syndromes/peripheral nerve tumour excision, or prophylactic use during other surgical procedures) - 6 months
- Neuroma management (treatment or prevention) - 12 months
- Reconstruction of peripheral nerve (including nerve transfer/free-functioning muscle transfer) - up to 24 months

Participants still in normal clinical follow-up will be asked to provide consent for data collection, and to complete a global rating of change questionnaire.

All patients who underwent (or undergo) a peripheral nerve procedure using Remplir with the site investigator(s) from the 1st January 2019 until closure of prospective recruitment will be screened for eligibility.
