Oner K, et al. - This study was attempted to ascertain the ideal placement of the lag screw taking into account the fracture morphology in the sagittal plane. Researchers constructed three different morphology of fractures on the sagittal plane in femur models obtained in 3D CT scanning: posteriorly angled (Type A), transverse (Type B), and anteriorly angled (Type C). The anteverted placement is ideal placement in type C fractures, while the ideal lag screw placement in a type A fracture in the sagittal plane is the retroverted placement. It was indicated that fracture morphology in the sagittal plane should be taken into account in the lag screw placement.
