Core Tip

Core tip: Sacral fractures following posterior lumbosacral fusion are rare. This article presents a case of totally displaced sacral fracture following posterior L4-S1 fusion. Computed tomography has been proved to be able to detect most such fractures and should probably be performed routinely when patients complain of renewed buttock pain within 3 mo after lumbosacral fusion. The majority of the patients responded well to conservative treatments, and extending the fusion construct to the iliac wings using iliac screws may be needed when there is concurrent fracture displacement, sagittal imbalance, neurologic symptoms, or painful nonunion.
