BACKGROUND CONTEXT: Lumbar epidural corticosteroid injections (LECI) are frequently used in the treatment of lumbar intervertebral disc herniation with radiculopathy and lumbar spinal stenosis. Although widely utilized, their effect on the outcomes and complications of subsequent surgery is unclear. Post-operative infection can be a morbid complication following spine surgery, and recent literature has suggested that the risk may be increased in patients undergoing lumbar spinal surgery who had previously received LECI...

BACKGROUND: Oblique lumbar interbody fusion is a commonly used surgical method of achieving lumbar interbody fusion. There have been some reports about complications of oblique lumbar interbody fusion at the L2-3 level. But to our knowledge, there have been no reports about ureter injury during oblique lumbar interbody fusion. We report a case of ureter injury during oblique lumbar interbody fusion to share our experience. CASE DESCRIPTION: A 78-year-old male patient presented with a history of lower back pain and neurogenic intermittent claudication...

BACKGROUND: Degenerative lumbar spinal stenosis (DLSS) is a common health problem in the elderly and usually associated with three-joint complex degeneration. Schmorl's nodes (SNs) are described as vertical herniation of the disc into the vertebral body through a weakened part of the end plate that can lead to disc degeneration. Since SNs can harm the spine unit stability, the association between DLSS and SNs is expected. The aim of this study is to shed light on the relationship between degenerative lumbar spinal stenosis and SNs...

PURPOSE: The aim of the present study was to examine the natural history in patients with lumbar spinal stenosis. The incidence of surgery for this condition has increased considerably during the past decades in spite of a fairly favorable natural history in previous studies. METHODS: 146 consecutive patients with clinical signs and image findings of lumbar spinal stenosis, who were not recommended surgical treatment, were followed; the reason as to why surgery was not recommended was a moderate symptom level...

INTRODUCTION: By using a combination of magnetic resonance imaging (MRI) and computed tomography (CT) of the lumbar spine, it is possible to distinguish between spinal stenosis caused by bone compression and specific soft tissue epidural intraspinal lesions that cause localized spinal canal stenosis and neural compression. Examples include facet cysts and yellow ligament hypertrophy. Many of these patients are elderly with medical comorbidities that make open surgery problematic. MATERIALS & METHODS: This is a study of patients with predominantly soft tissue stenosis being treated with targeted intraspinal radiofrequency (RF) heat ablation...

BACKGROUND: Lumbar decompression surgery is often used to treat neurological symptoms of the lower extremity as a result of lumbar disease. However, this method also leads to the improvement of the accompanying low back pain (LBP). We studied the extent of LBP improvement after lumbar decompression surgery without fusion and the associated preoperative factors. METHODS: Patients (n = 140) with lumbar spinal stenosis (n = 90) or lumbar disc herniation (n = 50) were included...

BACKGROUND: When considering various risk factors such as age, comorbidities, and complications related to the surgical procedure itself, open surgery in degenerative spinal stenosis is likely to cause more complications. Here, we report the surgical procedure and preliminary clinical results of percutaneous endoscopic stenosis lumbar decompression (PESLD) technique using a uniportal-contralateral approach for bilateral decompression of degenerative spinal stenosis. MATERIALS AND METHODS: Electronic medical records (EMR) of 48 consecutive patients who were treated between January 2016 and August 2016 were reviewed retrospectively...

RATIONALE AND OBJECTIVES: Emergency department (ED) patients with acute low back pain (LBP) may present with ambiguous clinical findings that pose diagnostic challenges to exclude cauda equina syndrome (CES). As a proof of concept, we aimed to determine the efficacy of a rapid lumbar spine (LS) magnetic resonance imaging (MRI) screening protocol consisting of a single 3D-T2 SPACE FS (3D-T2 Sampling Perfection with Application optimized Contrasts using different flip angle Evolution fat saturated) sequence relative to conventional LS MRI to exclude emergently treatable pathologies in this complex patient population...

INTRODUCTION: A small subset of patients who underwent successful vertebral compression fracture (VCF) augmentation procedures may develop subsequent pain requiring spinal injections. In a retrospective analysis, we determined whether the pain was related to the original fracture site or to another area within the lumbar or thoracic spine. The pain occurred either at the same/adjacent level and/or non-adjacent level as the VCF. Interventional treatments primarily targeted the facet joints, specifically in the form of facet joint blocks and/or radiofrequency ablation to the medial branches...

OBJECTIVE: To identify differences in health factors, neuromuscular attributes and performance-based mobility among community-dwelling older adults with symptomatic lumbar spinal stenosis (SLSS); and to determine which neuromuscular attributes are associated with performance-based measures of mobility. We hypothesized that: (1) community-dwelling older adults with SLSS would have poorer health, greater neuromuscular impairment and worse mobility; and (2) greater impairment in trunk extensor muscle endurance, leg strength, leg speed and knee flexion range of motion (ROM) would be associated with performance-based mobility...

Percutaneous endoscopic surgery for the lumbar spine, which was established in the last decade, requires only an 8-mm skin incision and causes minimal damage to the paravertebral muscles; thus, it is considered to be a minimally invasive technique for spinal surgery. It has been used to perform percutaneous endoscopic discectomy via two main approaches: the TF approach is a posterolateral one through the intervertebral foramen and can be done under local anesthesia; the IL approach is a more traditional one through the interlaminar space and is difficult to perform under local anesthesia...

Lumbar degenerative scoliosis is a relatively common problem, and is being treated more frequently due to the confluence of an aging population and an increased capacity and willingness to manage difficult problems in older patients. Lumbar degenerative scoliosis is a complex pathology as it often involves the intersection of degenerative spinal stenosis and spinal deformity. While previous studies provide an indication that these patients may benefit from surgical treatment, the substantial variability in treatment underscores the opportunity for improvement...

BACKGROUND: Decompression without fusion is a treatment option in patients with lumbar spinal stenosis (LSS) associated with stable low-grade degenerative spondylolisthesis (DS). A minimally invasive unilateral laminotomy (MIL) for "over the top" decompression might be a less destabilizing alternative to traditional open laminectomy (OL). OBJECTIVE: To review secondary fusion rates after open vs minimally invasive decompression surgery. METHODS: We performed a literature search in Pubmed/MEDLINE using the keywords "lumbar spondylolisthesis" and "decompression surgery...

INTRODUCTION: The debate on efficacy of fusion added to decompression for lumbar spinal stenosis (LSS) is ongoing. No meta-analysis has compared the effectiveness of decompression versus decompression plus fusion in treating patients with LSS. METHODS: A literature search was performed in the Web of Science, PubMed, Embase, and Springer databases from 1970 to 2016. Relevant references were selected and the included studies were manually reviewed. We included trials evaluating decompression surgery compared to decompression plus fusion surgery in treating patients with LSS...
