In 408 patients with degenerative lumbar spinal stenosis, sarcopenic obesity independently predicted worse ODI scores, more severe disc degeneration, foraminal stenosis, and Modic changes, supporting routine SO screening in preoperative workup.
Paraspinal Muscle Quality and Functional Outcome After Lumbar Spinal Stenosis Surgery.
In 344 lumbar spinal stenosis surgery patients, greater preoperative multifidus fatty infiltration—but not psoas size—predicted worse two-year disability outcomes and lower odds of meaningful improvement.
A Prospective Comparative Study of UBE-ULBD Versus Endo-ULBD for Lumbar Spinal Stenosis.
This RCT of 110 patients found biportal (UBE-ULBD) and single-port endoscopic (Endo-ULBD) decompression for lumbar stenosis yielded comparable clinical and radiological outcomes at 12 months, differing only in operative time and hospital stay.
In a Finnish registry of lumbar stenosis surgery, complications occurred in 16.8% of patients and were linked to older age, higher ASA grade, and multilevel/fusion surgery, substantially raising reoperation risk (especially with hematoma or infection).
Adding TLIF to posterior instrumentation for short-segment lumbar stenosis improves radiologic fusion but not functional outcomes, while increasing operative time and transfusion needs versus decompression alone.
Preoperative BMI-adjusted sarcopenia independently predicted worse 1-year disability and quality-of-life gains after lumbar spinal stenosis surgery.
Evaluation and Treatment of Tandem Spinal Stenosis.
This review discusses the prevalence, diagnostic challenges, and surgical management strategies—simultaneous versus staged—for tandem spinal stenosis affecting noncontiguous cervical and lumbar regions.
Revision after spinal stenosis surgery.
This literature review on reoperation after spinal stenosis surgery highlights causes like inadequate decompression or hardware malposition and stresses careful preoperative planning and intraoperative imaging to reduce revisions.
In degenerative lumbar spondylolisthesis with stenosis, adding intertransverse process arthrodesis to decompression produced significantly better pain relief than decompression alone.
