Littler heterodigital neurovascular island flap applied to tissue defects of the distal thumb

Abstract

To observe the results of Littler heterodigital island flap utilized in the treatment of pulpa defects of the thumb and evaluate our findings in the light of the literature. Twelve patients who applied to our clinic with defects on the distal tissue of the thumb between 2008 and 2016 were included in the study. Ten of the patients were male, 2 were female. Mean age was 40.25 (range, 30-55) years. Eight patients had tissue defects on their right 1st digital and 4 on their left. The sensory and functional outcomes and wound healing on the receiving site were evaluated. Additionally, we determined 2-point discrimination and cortical re-orientation. In all patients, the flap was healthy and no necrosis was observed. Mobility and stability of the thumb was optimal in all cases. In 2 patients, scar tissue development was observed at the donor site, but there was no functional deterioration. Sensory examination was normal in all patients. Mean value of 2-point discrimination was determined as 7 (range, 4-10) mmÂ’s. Littler neurovascular island flap is an effective treatment which re-establishes sensory ability in distal thumb injuries with tissue loss.
