AI Article Synopsis
- - This study is an observational cohort analysis comparing outcomes of lumbar spinal stenosis patients with and without spondylolisthesis, focusing on factors like function, disability, pain, and quality of life both before and after surgery.
- - A total of 704 patients were assessed, revealing no significant differences in symptoms or quality of life between the two groups before surgery or at the 2-year follow-up, despite higher complication rates in those with spondylolisthesis.
- - The overall conclusion indicates that having spondylolisthesis does not affect the symptom burden or clinical outcomes for patients with lumbar spinal stenosis up to two years post-surgery.
Article Abstract
Study Design: Observational cohort study (secondary analysis of two randomized trials).
Objective: The aim of this study was to investigate whether function, disability, pain, and quality of life before surgery and patient-reported outcome as well as complication and reoperation rates up to 2 years after surgery differ between lumbar spinal stenosis patients with and without spondylolisthesis.
Summary Of Background Data: Lumbar spinal stenosis is a degenerative condition of the spine, which appears with or without degenerative spondylolisthesis often presenting similar signs and symptoms.
Materials And Methods: This study is a secondary analysis of two randomized trials on patients with lumbar spinal stenosis with and without spondylolisthesis conducted at 16 public Norwegian hospitals. Disability, function, back pain, leg pain, quality of life, complication, and reoperation rates up to 2 years after surgery were compared between the two cohorts.
Results: A total of 704 patients were included in this study, 267 patients with spondylolisthesis [median age: 67.0 yr (IQR: 61.0-72.0 yr); 68.7% female] and 437 patients without spondylolisthesis [median age: 68.0 yr (IQR: 62.0-73.0 yr); 52.9% female]. In the linear mixed-model analysis there were no significant differences in disability, function, back pain, leg pain, and quality of life scores between the two cohorts of patient with and without spondylolisthesis before surgery or at 2 years of follow-up. The complication rate was 22.9% in patients with spondylolisthesis and 12.1% in patients without spondylolisthesis ( P <0.001). There were no significant differences in reoperation rates.
Conclusions: In patients with lumbar spinal stenosis the symptom burden before surgery and the clinical outcome up to 2 years after surgery were similar independently of a concomitant spondylolisthesis.
Level Of Evidence: II.

Cerebral venous sinus thrombosis is an uncommon sequela of low intracranial pressure, which may result from a lumbar puncture (LP). We describe a case of a patient in their 40s presenting with 48 hours of persistent headache following intrathecal administration of nusinersen for spinal muscular atrophy (SMA) type 3. There were no focal neurological signs or symptoms apart from baseline symmetrical proximal limb weakness attributed to SMA.

Background: Delta large-channel endoscopy and unilateral biportal endoscopy (UBE) are prominent minimally invasive techniques for treating lumbar spinal stenosis, known for minimal tissue damage, clear visualization, and quick recovery. However, rigorous controlled research comparing these procedures is scarce, necessitating further investigation into their respective complications and long-term effectiveness. This randomized controlled trial aims to compare their perioperative outcomes, focusing on postoperative recovery and complications over time.

Background: Epigenetic modifications have been proved to play important roles in the spinal degenerative diseases. As a type of noncoding RNA, the microRNA (miRNA) is a vital class of regulatory factor in the epigenetic modifications, while the role of miRNAs in the regulation of epigenetic modifications in ligamentum flavum hypertrophy (LFH) has not been fully investigated.
Methods: The miRNA sequencing analysis was used to explore the change of miRNA expression during the fibrosis of ligamentum flavum (LF) cells caused by the TGF-β1 (10 ng/ml).

Purpose: We sought to evaluate the incidence, natural history, and management of cystic spinal lesions following myelomeningocele/myeloschisis closure.
Methods: We performed a single-center retrospective review of all patients who underwent myelomeningocele/myeloschisis closure from 2013 to 2018 with follow-up to 5 years old.
Results: We analyzed 100 fetal repairs and 81 postnatal closures from 305 total surgeries.
