Using computer graphics to preserve function in resection of malignant melanoma of the foot

The increasing incidence of malignant melanoma challenges physicians to find innovative ways to preserve function and appearance in affected areas that require partial resection. We carefully planned the resection of a malignant lesion between the third and fourth toes of a 77-year-old man with the aid of computer technology. The subsequent excision of the third, fourth, and fifth digits was executed such that the new metatarsal arc formed would approximate the dimensions of the optimal hyperbola, thereby minimizing gait disturbance.
