Objectives: We have used a simple and very light weight external fixator we designed and discuss the results of distraction and advantages of this device . Materials and Methods: We applied our distractor to treat ۱۴ men and four women, with a mean age of ۳۹ years. There were three thumbs and ۲۳ fingers; ۲۶ digits (۱۸ patients) lengthened by distraction callotasis and second stage bone grafting evaluated accordingly. Results: All patients but one were satisfied with the results and a stable pinch and grip was obtained. After lengthening, all patients maintained sensation of the finger pulp, as assessed by the Semes - Weinstein test.
