PURPOSE: In this study, we addressed the correlation between the cross-sectional area (CSA) of the dural sac and the nerve root sedimentation sign (SedSign) and the correlation between the distance of claudication and the CSA of the dural sac or SedSign in patients with lumbar spinal stenosis. We also evaluated the reliability of clinical symptom prediction. METHODS: We checked claudication distance using a questionnaire, and we gauged low back pain when standing, referred pain, and radiating pain using visual analog scale scores...

Lumbar spinal stenosis (LSS) is characterized by the narrowing of the spinal canal, which subsequently induces impingement of neural elements in the lumbar spine. Thus, symptoms of LSS are typically associated with damage to those neural elements. Herewith, we target the genitourinary symptoms of LSS and the importance of differentiating these symptoms from other genitourinary pathologies, namely benign prostatic hyperplasia. Specifically, we review bladder dysfunction, lower urinary tract symptoms (e.g., urinary incontinence, detrusor overactivity and under-activity, as well as frequent urinary tract infections), renal osteodystrophy, and sexual dysfunction (e...

OBJECT: Although the sagittal spinal balance plays an important role in the spinal deformity surgery, its role in decompression surgery for lumbar canal stenosis is not well understood. To investigate the hypothesis that the sagittal spinal balance also plays a role in decompression surgery for lumbar canal stenosis, we performed a prospective cohort study analyzing the correlation between the preoperative lumbar lordosis and the outcome. MATERIALS AND METHODS: We analyzed a cohort of 85 consecutive patients who underwent decompression for lumbar canal stenosis during the period from 2007 to 2011...

BACKGROUND: Extreme lateral interbody fusion (XLIF) has rapidly become a popular operative procedure for lumbar canal stenosis and scoliosis. This approach provides direct access to the lateral aspect of the disc with minimal disruption of spinal structures, including ligaments and muscles. However, it involves risk of injuries to the lumbar nerve plexus, segmental artery and intestinal tract because of the limited surgical field. This study aimed to clarify the benefit of using a microendoscope to prevent these injuries...

Lumbar spinal stenosis (LSS) is a frequent cause of chronic low back and lower extremity pain in older patients. Symptomatic LSS typically is described as neurogenic claudication consisting of pain, weakness, numbness, and/or fatigue arising in the back and radiating into the buttock, thigh, or lower leg. The diagnosis is complicated by lack of reliable clinical or x-ray criteria. North American Spine Society guidelines recommend magnetic resonance imaging study without contrast to confirm anatomic narrowing of the spinal canal or nerve root impingement...

We present a case of double-crushed L5 nerve root symptoms caused by inside and outside of the spinal canal with spur formation of the lumbosacral transitional vertebra (LSTV). A 78-year-old man presented with 7-year history of moderate paresis of his toe and left leg pain when walking. Magnetic resonance imaging (MRI) revealed spinal stenosis at the L3/4 and 4/5 spinal levels and he underwent wide fenestration of both levels. Leg pain disappeared and 6-min walk distance (6MWD) improved after surgery, however, the numbness in his toes increased and 6MWD decreased 9 months after surgery...

Our study aimed to identify possible single nucleotide polymorphisms (SNPs) via a genome-wide association study (GWAS) approach and a candidate gene platform that were associated with lumbar developmental spinal stenosis (DSS). Southern Chinese population-based study volunteers were assessed (age range: 18-55 years). DSS was defined as the anteroposterior bony spinal canal diameter on T1-weighted axial MRI of L1 to S1. Genotyping was performed using the Illumina HumanOmniZhongHua-8 BeadChip. Using the canal diameter as the quantitative trait, genomic statistical analyses was performed...

PURPOSE: Lumbar spinal canal stenosis (LSCS) is associated with fibrosis, decreased elastin-to-collagen ratio, and hypertrophy of the ligamentum flavum (LF). Diabetes mellitus (DM) is known to cause metabolic disturbances within the extracellular matrix in multiple tissues. These alterations may play a major role in the severity of clinical symptoms of LSCS affecting diabetic patients. We aimed to examine the hypothesis that DM may contribute to the LF changes seen in patients with LSCS...

Percutaneous endoscopic surgery for the lumbar spine has become established in the last decade. It requires only an 8 mm skin incision, causes minimal damage to the paravertebral muscles, and can be performed under local anesthesia. With the advent of improved equipment, in particular the high-speed surgical drill, the indications for percutaneous endoscopic surgery have expanded to include lumbar spinal canal stenosis. Transforaminal percutaneous endoscopic discectomy has been used to treat intervertebral stenosis...

A 66-year-old male patient presented with symptoms and signs of L4/5 radiculopathy. He was found to be anaemic with elevated inflammatory markers and deranged hepatic enzymes. Imaging revealed lumbar canal stenosis and the presence of pyogenic liver abscesses from which Fusobacterium nucleatum and Streptococcus vestibularis were isolated. The hepatic abscesses were attributed to asymptomatic diverticular perforation. Multiple coexisting incidental infections were discovered, including oesophageal candidiasis, Helicobacter pylori, stool cultures positive for Strongyloides stercoralis, and sputum cultures positive for Enterobacter cloacae, Escherichia coli and Mycobacterium avium Extensive investigations for possible underlying immunosuppression were negative...

INTRODUCTION: Lumbar fusion is one of the most widespread techniques to treat degenerative lumbar pathology. To prevent complications such as non-union or adjacent segment degeneration, dynamic stabilization techniques were developed, but with controversial results. The aim of the present study was to compare long-term radiologic and clinical results between fusion and dynamic stabilization. MATERIAL AND METHODS: A single-center retrospective study included patients with recurrent lumbar discal hernia or lumbar canal stenosis managed by posterolateral fusion or by dynamic stabilization associated to neurologic release...

Ligamentum flavum (LF) hypertrophy causes lumbar spinal canal stenosis, leading to leg pain and disability in activities of daily living in elderly individuals. Although previous studies have been performed on LF hypertrophy, its pathomechanisms have not been fully elucidated. In this study, we demonstrated that infiltrating macrophages were a causative factor for LF hypertrophy. Induction of macrophages into the mouse LF by applying a microinjury resulted in LF hypertrophy along with collagen accumulation and fibroblasts proliferation at the injured site, which were very similar to the characteristics observed in the severely hypertrophied LF of human...

BACKGROUND: The intervertebral disc is the largest avascular structure in the body. It relies on passive diffusion from arteries at the periphery of the disc for nutrition. Previous studies have suggested a correlation between vascular disease and lumbar degenerative disk disease (DDD), but the association with facet arthritis and stenosis has not been evaluated. OBJECTIVE: To evaluate the degree of lumbar artery stenosis, aortic atherosclerosis on computed tomography angiography, and its relationship to lumbar DDD, facet arthritis, and spinal canal stenosis...
