Overview
Brief Summary
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.
Detailed Description
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.

Eligibility Criteria
Inclusion Criteria
- •The pulp or fingertip defect in only one finger
- •A defect greater than or equal to 1.5 cm in length
- •Necessity to preserve finger length
- •A patient between 18 and 60 years of age
Exclusion Criteria

Outcomes
Primary Outcomes
static 2-point discrimination (2PD) test
Time Frame: 18 months to 26 months
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.
Secondary Outcomes
- Cold intolerance(18 months to 26 months)
