Description
Fan Mo and Shaoqi He write a 2026 commentary on a computer model of spinal fusion surgery. The target study used finite element analysis to test cement support for pedicle screws in multilevel lumbar fusion. Cement can steady screws in weak bone, but it may also stress the next segment.
The letter questions the main stress measure used to predict screw loosening. Peak von Mises stress, the authors argue, tracks real loosening poorly in validation work. A reported fracture risk at the top lumbar level also draws their doubt. Sharper metrics would make such models more useful at the bedside. The exchange shows peer critique at work.
