Three-Dimensional Starch Model for Simulation of Corrective Osteotomy for a Complex Bone Deformity: A Case Report

Abstract

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.

Three-Dimensional Computed Tomography Assessment and Planning for Severe Lower Limb Deformities: A Case Report of Bilateral Fibular Hemimelia

“…The development of 3D-CT has revolutionized the field of imaging in a variety of orthopedic surgeries. Reconstructed 3D-CT images have been widely used for preoperative planning [13][14][15][16][17][18]. Here we conducted a 3D-CT assessment of alignment for lower limb deformities using such images.…”
