nerve graft
Surgical procedure using donor nerve tissue to bridge gaps in damaged nerves and restore function.
Full Definition
A nerve graft is a reconstructive procedure where a segment of nerve tissue is harvested from a donor site (often a sensory nerve) and used to bridge a gap in a damaged nerve. This technique is employed when primary nerve repair is not possible due to significant nerve loss or when tension-free approximation cannot be achieved. Common donor nerves include the sural nerve and medial antebrachial cutaneous nerve. The procedure requires microsurgical techniques and results in the sacrifice of donor nerve function in exchange for restoration of more critical motor or sensory function.
Usage
Usage note: Specify donor and recipient nerves for clarity in surgical documentation.
