As the donor nerve attached with the flap, the dorsal branch of the digital nerve and the dorsal digital nerve is commonly used for finger pulp reconstruction.This study compares two donor nerves: the dorsal branch of the digital nerve and the dorsal digital nerve.
The investigators compares two donor nerves attached with the flap for sensory reconstruction of finger pulp: the dorsal branch of the digital nerve and the dorsal digital nerve. The main outcomes were static 2-point discrimination and Semmes-Weinstein monofilament scores of the flap, and pain and cold intorlence of the reconstructed finger.

static 2-point discrimination (2PD) test
The test points are at the center of the radial or ulnar portion of the pulp. Each area is tested 3 times with a Discriminator. We stop at 4mm as a limit of 2PD and consider this normal.
Time frame: 18 months to 26 months
Cold intolerance
Cold intolerance in the reconstructed finger is assessed using the self-administered Cold Intolerance Severity Score questionnaire \[10\]. The maximum score is 100 and was group into 4 ranges (0-25, 26-50, 51-75, and 76-100), corresponding to mild, moderate, severe, and extreme severity, respectively.
Time frame: 18 months to 26 months
