About

Reconstruction of soft-tissue defects in multiple digits poses a significant challenge. This article reports simultaneous reconstruction of multiple small-to-moderate soft-tissue defects using regional dorsal digital island flaps and evaluated the efficacy of their application in such complex situation. A retrospective study will be conducted with 26 patients who had multiple-digit soft-tissue defects treated with regional dorsal digital island flaps. At the final follow-up, we will evaluate the efficacy of their application in such complex situation.

Full description

For the recipient where sensory restoration is important, sensation of the flaps is assessed using static two-point discrimination (2PD) and Semmes-Weinstein monofilament (SWM) testing at final follow-up. The cold intolerance of the injured finger is measured using the self-administered Cold Intolerance Severity Score questionnaire that was rated into mild, moderate, severe, and extreme (0-25, 26-50, 51-75 and 76-100). The pain of the injured finger is given subjectively by the patient using a grading system that included grade 1, none; grade 2, mild, no interference with daily activities; grade 3, moderate, patient works but has some limitation in use of the hand because of pain; and grade 4, severe, cannot work or use hand. To sum up, patients report their satisfaction with functional recovery of the injured finger according to the Michigan Hand Outcomes Questionnaire that was based on a 5-point response scale.
