Upper Instrumented Vertebra Hounsfield Unit Assessment and Association With Mechanical Complications Following Posterior Spinal Fusion
CT-based measurement of HU at the upper instrumented vertebra has excellent intrarater and good interrater reliability. In this cohort of lumbar and thoracolumbar spinal fusion patients, patients with HU under 105 at the UIV had an increased risk of mechanical and junctional complications following spinal fusions. Future studies may work to refine HU assessment and the association with postoperative complications, as using HU to guide surgical candidacy and UIV selection may be beneficial.
