Nerve Transfer for Finger Sensory Reconstruction With Dorsal Branch of the Digital Nerve

Not Applicable

Completed

• Conditions: Sensory Restoration of the Reconstructed Finger Pulps; Cold Intolerance of the Reconstructed Finger; Pain of the Reconstructed Finger
• Interventions: Procedure: Nerve transfer

• Registration Number: NCT01559337
• Lead Sponsor: The Second Hospital of Tangshan

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.

Arm && Interventions

Group	Intervention	Description
Nerve repair	Nerve transfer	the dorsal branch of the proper digital nerve was used as a pedicle nerve for reconstructing PDN defects

Primary Outcome Measures

Name	Time	Method
static 2-point discrimination (2PD) test	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 Outcome Measures

Name	Time	Method
self-administered Cold Intolerance Severity Score (CISS) questionnaire	26 months	The maximum score was 100 and was grouped into 4 ranges (0-25, 26-50, 51-75, and 76-100), corresponding to mild, moderate, severe, and extreme severity, respectively.
