Preplanning for correctional osteotomies: sculpture your result

Traditionally, correctional osteotomies are pre-planned on paper, but there is also the possibility of assembling a stereolithographic model from CT-scan data or even employing computer-assisted 3D virtual osteotomy systems for the more complicated cases. The simplicity of the one was combined with the extra dimension of the other. This resulted in a method where preplanning was performed with a clayed model. With a case report of a posttraumatic malunion, the procedure is illustrated for a correctional osteotomy in the proximal femur.
