An 11 year-old girl had 66 degrees of kyphosis in the thoracolumbar junction. For the purposeof planning for kyphosis correction, we created a 3-D, full-scale model of the spine and consultedspinal navigation. Three-dimensional models are generally used as tactile guides to verify the surgical approach and portray the anatomic relations specific to a given patient. We performed posterior fusion from ThlO to L3, and vertebral column resection of Thl2 and LI. Screw entry points, directions, lengths and diameters were determined by reference to navigation. Both tools were usefulin the bone resection We could easily detect the posterior element to be resected using the 3D model. During the anterior bony resection, navigation helped us to check the disc level and anterior wall of the ver-tebrae, which were otherwise difficult to detect due to their depth in the surgical field. Thus, the combination of navigation and 3D models helped us to safely perform surgery fora patient with complex spinal deformity.
