Brief Summary
The purpose of our project is to determine if incorporating preventative surgical techniques such as regenerative peripheral nerve interfaces (RPNI) into sural nerve biopsy can reduce the incidence of symptomatic neuroma formation. Findings from this study will inform best practice guidelines and can dramatically impact patient care, improve patient quality of life, and reduce the number of required repeat operations.

Study Arms (2)
Biopsy Alone
ACTIVE COMPARATORPatients in this group will only undergo sural nerve and muscle biopsy
Biopsy and RPNI
EXPERIMENTALPatients in this group will undergo RPNI during their sural nerve and muscle biopsy
Interventions
RPNI is a surgical technique which wraps denervated muscle targets around severed nerve ends.
Eligibility Criteria
You may qualify if:
- Patient 18 years old and older who are referred for sural nerve and muscle biopsy to the University of British Columbia Division of Plastic Surgery from January 2025 onwards for diagnostic or prognostic clarification of a medical condition.
You may not qualify if:
- Patients with previous nerve trauma (traumatic injury, surgery, or repeat biopsy) of biopsied nerve.
