Pedicle screw placement usingcortical bone trajectory has become a popular method of fixation especially in minimal invasive spine surgery over the last few years. Complications of this technique have been rarely reported in the literature. A clear understanding of fractures and screw loosening is crucial before embarking on this new surgical technique. Fatigue failure in osteoporotic bone using this technique is alarming and warrants further study to understand its indication.
