- Procedure: Composite Flap
- Registration Number
- NCT01837407
- Lead Sponsor
- The Second Hospital of Tangshan
- 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.

- Primary Outcome Measures
Name Time Method Static 2-point discrimination test 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.
- Secondary Outcome Measures
Name Time Method Cold Intolerance Severity Score (CISS) questionnaire. 18 months to 24 months The maximum score is 100 and is grouped into 4 ranges (0-25, 26-50, 51-75, and 76-100), corresponding to mild, moderate, severe, and extreme severity, respectively.
