Soft Tissue Defect of the Finger
Conditions
Keywords
Dorsal digital nerve, dorsal branch of the digital nerve, dorsal branch of the digital artery, dorsal digital island flap, finger pulp defect.
Brief summary
As the donor nerve attached with the flap, the dorsal branch of the digital nerve and the dorsal digital nerve is commonly used for finger pulp reconstruction.This study compares two donor nerves: the dorsal branch of the digital nerve and the dorsal digital nerve.
Detailed description
The investigators compares two donor nerves attached with the flap for sensory reconstruction of finger pulp: the dorsal branch of the digital nerve and the dorsal digital nerve. The main outcomes were static 2-point discrimination and Semmes-Weinstein monofilament scores of the flap, and pain and cold intorlence of the reconstructed finger.
Interventions

Eligibility
Inclusion criteria
* The pulp or fingertip defect in only one finger * A defect greater than or equal to 1.5 cm in length * Necessity to preserve finger length * A patient between 18 and 60 years of age
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| static 2-point discrimination (2PD) test | 18 months to 26 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. We stop at 4mm as a limit of 2PD and consider this normal. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Cold intolerance | 18 months to 26 months | Cold intolerance in the reconstructed finger is assessed using the self-administered Cold Intolerance Severity Score questionnaire \[10\]. The maximum score is 100 and was group into 4 ranges (0-25, 26-50, 51-75, and 76-100), corresponding to mild, moderate, severe, and extreme severity, respectively. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Pain | 18 months to 26 months | Using the visual analogue scale (VAS), patients are asked to report pain sensations of the reconstructed pulps and donor sites. The VAS consists of a 10 cm line that is grouped into mild (0-3 cm), moderate (4-6 cm) and severe (7-10 cm). |
