Improvement in spinopelvic parameters after laminectomy and complete factectomies above prior fusion facilitated by posterior arthroplasty: illustrative case

Alleviation of lumbar stenosis not only provided symptomatic relief but also improved this patient's sagittal imbalance, illustrating the contribution of lumbar stenosis to sagittal imbalance. Laminectomy with total factectomies was facilitated by the posterior arthroplasty device, which prevented pathological motion despite the destabilizing decompressive procedure. https://thejns.org/doi/10.3171/CASE25565.
