Abstract

A sacral insufficiency fracture is a rarely reported complication after lumbosacral fusion. As the majority of those undergoing surgery are elderly patients with degenerative disease, osteoporosis is usually involved along with other reported risk factors such as female, obesity, and multi-segment fusion. Through two cases experienced by the authors, this paper reports a newly found risk factor (cement-augmented pedicle screw), and the fracture treatment process with a review of the relevant literature.
