Evaluation of recurrent macrodactyly with three-dimensional imaging

Macrodactyly is a deformity that may progress beyond initial surgical resection. Three-dimensional computed tomography imaging may aid in the surgical planning, given the osseous irregularities that may exist. The objective in revisional surgery of this type is to provide the most functional and cosmetic result. In this case, the hallux was saved when the patient previously had requested an amputation. The case also illustrates that when earlier surgery has been performed, the classic approaches to macrodactyly advocated in the literature may not be feasible. The surgeon must then approach the deformity with some flexibility, and three-dimensional imaging may be a useful tool.
