Abstract
We present 19 ray lengthenings in 14 patients done with a small external fixator. In six cases the thumb was lengthened and in the other 13 cases, other digital rays. The most frequent reason for lengthening was an amputation sustained in a work accident.
All the lengthenings were done by an osteotomy and subsequent gradual distraction with a small external fixator. The mean lengthening achieved was 20 mm (range, 0–32). An iliac-crest graft was needed in nine cases, corrective osteotomy in five cases and a deepening of the web in the six cases of thumb lengthening. In five cases an additional technique was needed to achieve bony consolidation. We have analysed the functional results and the ability to perform activities of daily living and resume employment. Although most of the patients had multiples injuries, the results have been very favourable, achieving a very high level of patient satisfaction.
