Overview

Brief Summary

Complex digital injuries involving soft tissue loss and digital nerve defect pose challenging problems for hand surgeons. This study uses the heterodigital arterialized nerve pedicle flap including the dorsal branch of the digital nerve for reconstructing a digital neurocutaneous defect of the proximal phalanx.

Eligibility Criteria

Inclusion Criteria

•a neurocutaneous defect at the proximal phalanx
•a soft tissue defect on the volar, dorsal, and contiguous lateral aspects of adjacent fingers .associated digital nerve defect.

Exclusion Criteria

Outcomes

Primary Outcomes

Static 2-point discrimination test

Time Frame: 18 months to 24 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. The investigators stop at 4mm as a limit of 2PD and consider this normal.
