title: A new surgical method for treating lateral ray polydactyly with brachydactyly of the foot: lengthening the reconstructed fifth toe.
abstract: Lateral ray polydactyly is the most common anomaly of the foot. However, when both the fifth and sixth toes are markedly shorter than a normal toe, reconstruction of a normal-length fifth toe has not been performed, because the toe rarely serves a functional purpose. The authors devised a new method whereby the fifth toe could be lengthened using the excess toe as a composite flap. Fifteen patients (15 toes) underwent our procedures and were evaluated in this study. The stepladder island flap is used. The decision as to which toe to use as the flap was made preoperatively based on nail size, and its morphologic and radiographic conditions. Stepladder incision lines were designed on the dorsal and plantar sides of the duplication. Care was taken to preserve the neurovascular bundle with the subcutaneous pedicle and osteotomies were made at the middle phalanx of the flap and the distal or middle phalanx of the recipient in almost all cases. The elevated composite toe flap was advanced and the bone was fixed rigidly for 1-2 months after the operation. During our follow-up periods, the reconstructed toes grew normally, and good aesthetic results had been achieved apart from the bulkiness of the reconstructed toes. There was no deficiency in circulation or function for walking, running, or shoe-fitting in this series.
