简要总结
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.
详细描述
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.

结局指标
主要结局
static 2-point discrimination (2PD) test
时间窗: 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.
次要结局
- Cold intolerance(18 months to 26 months)
