Description
Dongyue Li and co-authors ask whether hip coverage keeps spinal balance after a major fusion in a 2026 study. Adults with spinal deformity often get screws anchored to the pelvis, yet some lose upright balance over the next two years. The team tracked two hundred twenty four patients and grouped them by how femoral head coverage changed after surgery.
Patients whose coverage barely changed showed more balance loss, more forward drift, and more junction problems at two years. Among those whose coverage did shift, failure to recover it also predicted decline. Two change thresholds flagged risk with fair accuracy. The authors read hip flexibility as a reserve: when the hip cannot adjust, the spine pays.
