ABSTRACT
Polydactyly is a common congenital deformity of the foot that can be categorized as preaxial, central, or postaxial. Current treatments involve resecting the supernumerary toe(s) and repairing the normal toe(s) and soft tissue. Here, we present the first published report describing a very rare case of polydactyly of the foot, in which the supernumerary toe originated from a deformed calcaneus, which formed an abnormal bony bump. Preoperatively, 3-dimensional (3D) computed tomography reconstruction images revealed the morphology of the deformed toe and calcaneus, and gait analysis showed an abnormal weightbearing zone in the left foot. The 3D printing technology and a specially designed 3D-printed guiding plate were used for osteotomy. Postoperatively, x-ray showed that the calcaneus had a normal shape and surface, whereas gait analysis showed that the left foot was uniformly loaded and the area of pain was eliminated. Our findings should raise awareness among clinicians that a 3D-printed guiding plate is useful in the treatment of such an unusual deformity.
