BACKGROUND To evaluate the utility of additional fixation methods and to suggest a method of reduction in the treatment of unstable pertrochanteric femur fractures with a sliding hip screw (SHS). METHODS A retrospective study was performed on thirty patients with unstable pertrochanteric femur fractures, who were operated on with a SHS between September(More)
We have carried out a biomechanical study to investigate the effect on flexion, extension, and rotation of seven systems of fixation on five cadaveric lumbar spines. Pedicle fixation proved the most effective method to restrict these movements. Facet screw fixation was also successful. Harrington distraction rods, the Hartshill rectangle and the Luque(More)
