Lumbar spinal stenosis (LSS) can impair blood flow to the spinal nerves giving rise to neurogenic claudication and limited walking ability. Reducing lumbar lordosis can increases the volume of the spinal canal and reduce neuro-ischemia. We developed a prototype LSS belt aimed at reducing lumbar lordosis while walking.
Patients with lumbar spinal stenosis (LSS) who have radiographically similar degrees of stenosis may not necessarily exhibit equivalent symptoms. As part of a cross-sectional study, we examined factors associated with symptomatic LSS (sLSS) in the general population of Japan.
The degenerative lumbar spinal stenosis is one of the most commonly treated spinal disorders in older adults; despite its increasing frequency, it is not yet clear what the most effective therapy might be. The aim of this study is to investigate the very long term results of a homogenized cohort of patients suffering from lumbar spinal stenosis: the first subset of patients operated on with laminectomy and the second subset of patients was also advised to undergo laminectomy but never operated on.
Retrospective study OBJECTIVE.: To examine practice variation in the treatment of lumbar spinal stenosis and identify targets for reducing variation.
Lumbar spinal stenosis (LSS) is a narrowing of the spinal canal due to spinal degeneration, and its main clinical symptom is neurogenic claudication. Surgical treatment is pursued for patients who do not improve with conservative care. Patients with symptomatic LSS who also have significant medical comorbidities, although clearly in need of intervention, are unattractive candidates for traditional open lumbar decompressive procedures. Thus it is important to explore minimally invasive surgical techniques...
Observational prospective study.
The purpose of this study was to provide a new classification of the lateral region of the lumbar canal (LLSC) and evaluate the clinical outcome of surgical treatment of LLSC stenosis guided by the classification.
Decompression surgery for lumbar spinal stenosis (LSS) is the most common spinal procedure in the elderly. To avoid persisting low back pain, adding arthrodesis has been recommended, especially if there is a coexisting degenerative spondylolisthesis. However, this strategy remains controversial, resulting in practice-based variation.
To compare the effectiveness of a comprehensive non-surgical training program to a self-directed approach in improving walking ability in lumbar spinal stenosis.
Degenerative lumbar spinal stenosis is a condition related to aging in which structural changes cause narrowing of the central canal and intervertebral foramen. It is currently the leading cause for spinal surgery in patients over 65 years. Interspinous process devices (IPDs) were introduced as a less invasive surgical alternative, but questions regarding safety, efficacy, and cost-effectiveness are still unanswered.
In degenerative lumbar spinal stenosis (DLSS) variability of symptoms according to the severity of stenosis is not well understood. Therefore, another factor that impacts functional outcomes of DLSS patients has been evoked: patient's comorbidities. The aim of this study was to investigate influence of comorbidities on clinical symptoms and functional outcomes in DLSS patients.
Lumbar spinal stenosis is a condition where the neural structures are compressed in the narrowed spinal canal and often situated only within a single specific segment of the spine, most frequently in the lumbar spine. A case report demonstrates a surgical solution of lumbar spinal stenosis with using oxidized cellulose as a prevention of post-operative adhesions and failed back syndrome. A female patient (68) with a significant pain of the lumbar spine lasting for a number of months due to advanced spondylo...
This study evaluated the long-term durability of the minimally invasive lumbar decompression (MILD) procedure in terms of functional improvement and pain reduction for patients with lumbar spinal stenosis and neurogenic claudication due to hypertrophic ligamentum flavum. This is a report of 2-year follow-up for MILD study patients.
To investigate the prevalence of frailty in patients with symptomatic lumbar spinal stenosis (LSS) and a propensity score-matched control group, and to analyze the association between symptomatic LSS and frailty.
The aim of the study was to evaluate the safety and short-term effects of dynamic stabilization via minimally invasive system for degenerative lumbar spinal stenosis. Patients with degenerative lumbar spinal stenosis and treated with Transforaminal Lumbar Interbody Fusion via minimally invasive minimally system (mis-TLIF) were served as the control group.From April 2011 to March 2015, 47 patients (29 male, 18 female; mean age 47.6 [range, 26-52] years) with lumbar spinal stenosis were treated with decompres...
Decompression alone to treat degenerative lumbar stenosis with and without concomitant degenerative spondylolisthesis (DS; non-DS) has shown ambiguous results in the literature.
Examining spine surgery patterns over time is crucial to provide insights into variations and changes in clinical decision making. Changes in the number of surgeries, surgical methods, reoperation rates and cost-effectiveness were analyzed for all patients who underwent surgery for lumbar spinal stenosis without spondylolisthesis in 2003 (2003 cohort) and 2008 (2008 cohort).
Traditional open approach is an efficient way to treat lumbar spinal stenosis (SS) combined with disk herniation (DH); however, risk factors such as advanced age, osteoporosis etc. are associated with the complications after the surgery. This study aims to analyze the early clinical and radiological outcomes of treatment on SS&DH by using newly developed minimal invasive TESSYS-ISEE technique.
Although a number of prognostic factors have been demonstrated to be associated with surgical outcome of degenerative lumbar spinal stenosis (DLSS), no study has investigated the relation between hand grip strength (HGS) and treatment outcome of DLSS.
Lumbar spinal stenosis (LSS) is one of the most frequent neurosurgical affections. It has been reported that the anatomical shape of the spinal canal (oval, round, trefoil) predicts outcome of bilateral decompression performed in an undercutting technique via a unilateral laminotomy in monosegmental LSS. The poorest results were observed in a trefoild spinal canal, leading to the proposal of using a bilateral instead of a unilateral laminotomy. We have been routinely performing a unilateral microsurgical ap...
Various minimally invasive techniques have been described for the decompression of lumbar spinal stenosis (LSS). However, few reports have described the results of endoscopic posterior decompression (EPD) with laminectomy performed under local anesthesia. This study aimed to evaluate the clinical and radiological outcomes of EPD performed under local anesthesia in patients with LSS and to compare the procedural outcomes in patients with and without preoperative spondylolisthesis.
Degenerative spondylolisthesis (DS) and lumbar spinal stenosis (LSS) are the most common degenerative spinal diseases. The evaluating of spinopelvic sagittal alignment of the two diseases using pelvic radius (PR) technique have not been reported. The purpose of this study was to use PR measurement technique to compare the differences in spinopelvic sagittal alignment between DS and LSS.
Lumbar spinal stenosis (LSS) and low-grade degenerative spondylolisthesis are frequently associated with facet joint degeneration, considered the main cause of low back pain. Surgery is the treatment of choice in patients affected by LSS unresponsive to conservative treatment. The aim of this study was to evaluate the clinical and radiologic outcome of patients treated with posterior decompression and transfacet fixation for single-level LSS and facet joint degeneration.
Full endoscopy spine surgery is one of the minimally invasive procedures for lumbar spine disease and is especially popular in East Asia. As for the interlaminar approach, lumbar recess stenosis can be manipulated through a uniportal bigger diameter working channel spinal endoscope or a smaller one, or a biportal arthroscope. Each kind of procedure has its advantages and shortcomings. Here, a novel experience in biportal interlaminar approach for lumbar recess stenosis is presented. A smaller uniportal spin...
Retrospective cohort study OBJECTIVE.: The purpose of this study is to characterize the utilization and costs of MNTs prior to spinal fusion surgery in patients with symptomatic lumbar stenosis or spondylolisthesis.
