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.

Condition or disease Intervention/treatment Phase
Sensory Restoration of the Reconstructed Finger Pulps Cold Intolerance of the Reconstructed Finger Pain of the Reconstructed Finger Procedure: Nerve transfer Not Applicable

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 17 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Study Start Date : May 2007
Actual Primary Completion Date : June 2009
Actual Study Completion Date : January 2012

Arm Intervention/treatment
Nerve repair
the dorsal branch of the proper digital nerve was used as a pedicle nerve for reconstructing PDN defects
Procedure: Nerve transfer
the dorsal branch was used as a pedicle nerve for reconstructing PDN defects
Other Name: Local pedicle nerve transfer

Primary Outcome Measures :
  1. 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 Outcome Measures :
  1. self-administered Cold Intolerance Severity Score (CISS) questionnaire [ Time Frame: 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.
