Fig. 2From: Ideal T1 laminar screw fixation based on computed tomography morphometry a Process for creating the modified sagittal reconstruction. b Minimal outer cortical (T) and cancellous heights (Ts) obtained at the narrowest point of the lamina in the modified sagittal reconstruction. c Spinous process height (H) was measured at the cross-point of the bilateral ideal laminar screw placement in the modified sagittal reconstructionBack to article page
