Three-dimensional starch model for simulation of corrective osteotomy for a complex bone deformity: a case report.
The complex valgus deformity of the right ankle of a 24-year-old Maffucci syndrome man was corrected by three-dimensional osteotomy followed by limb lengthening. Before surgical correction of the deformity, we used computed tomography data to make a life-size three-dimensional plastic model of the deformed ankle for an accurate understanding of the anatomical deformity. We then used this model to perform a simulated osteotomy. The real osteotomy was performed immediately afterwards and valgus and recurvatum deformities were corrected accurately. We recommend simulated surgery using a three-dimensional plastic model which will improve the pre-operative planning technique and the accuracy of the end results.
