Brief summary
Soft tissue reconstruction in the finger continues to evolve. The dorsum of the finger is a reliable flap donor site in reconstructive hand surgery because of its similar quality to the original. The dorsal homodigital island flap can be used as a reliable alternative for reconstructing small to moderate defects of the fingers. In this retrospective study, the investigators would evaluate the efficacy of the technique for tissue reconstruction in different regions of the finger, with an emphasis on sensibility, pain and donor site morbidity.
Detailed description
At final follow-up, sensory restoration of the flap is measured using the static 2-point discrimination test and Semmes-Weinstein monofilament test. We evaluate pain sensations of the reconstructed fingers and donor sites with a visual analog scale. The system consist of a 10 cm line that is grouped into mild (0-3 cm), moderate (4-6 cm) and severe (7-10 cm). Active motion of the joints is measured using a goniometer. The motion arcs of the reconstructed fingers are compared with the opposite side.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Static 2-point discrimination test | 18 months to 24 months | The test point is at the center of the flap. Each area was tested 3 times with a Discriminator (Ali Med, Dedham, MA). We stop at 4mm as a limit of 2PD and considered this normal. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Cold intolerance | 18 months to 24 months | We access the cold intolerance of the injured and donor fingers using the self-administered Cold Intolerance Severity Score questionnaire10 that is rated into mild, moderate, severe, and extreme (0-25, 26-50, 51-75 and 76-100). |
