Study Overview
Brief Summary
A proper digital nerve (PDN) defect causes partial or complete sensory loss of the finger pulp, which results in functional disability.The dorsal branch of the PDN can be transferred for reconstruction of such nerve defects.In this study, the investigators modified the Lesavoy et al' technique and evaluated the efficacy of dorsal sensory branch transfer for PDN defects. For comparison, the investigators collected a consecutive series of 32 patients with finger PDN defects treated using a traditional sural nerve graft from February 2005 to October 2008.

Nerve repair
the dorsal branch of the proper digital nerve was used as a pedicle nerve for reconstructing PDN defects
Intervention: Nerve transfer (Procedure)
Outcomes
Primary Outcomes
static 2-point discrimination (2PD) test
Time Frame: 26 months
At final follow-up, we measured the sensibility of the pulps and the donor sites using the static 2-point discrimination (2PD) test. The test points were at the center of the radial or ulnar portion of the pulp and the donor sites separately. Each area was tested 3 times with a Dellon-Mackinnon discriminator. Two out of 3 correct answers were considered proof of perception before proceeding to another lower value.
Secondary Outcomes
- self-administered Cold Intolerance Severity Score (CISS) questionnaire(26 months)
