Non-Surgical Interventions for Lumbar Spinal Stenosis Leading To Neurogenic Claudication: A Clinical practice guideline.

J Pain 2021 Apr 12. Epub 2021 Apr 12.

Health Systems Management, Rush University, Chicago, Illinois, USA; Director of Research, American Hip Institute. Electronic address:

Lumbar spinal stenosis (LSS) causing neurogenic claudication (NC) is increasingly common with an aging population and can be associated with significant symptoms and functional limitations. We developed this guideline to present the evidence and provide clinical recommendations on non-surgical management of patients with LSS causing NC. Using the GRADE approach, a multidisciplinary guidelines panel based recommendations on evidence from a systematic review of randomized controlled trials and systematic reviews published through June 2019, or expert consensus.

Transverse myelitis masquerading as cauda equina syndrome, stroke and cervical myelopathy.

Biomedicine (Taipei) 2020 28;10(1):45-50. Epub 2020 Mar 28.

Division of Spine, Department of Orthopaedic Surgery, Tan Tock Seng Hospital, Singapore.

Transverse myelitis is an uncommon but well-defined neurological syndrome. However, a high index of suspicion is needed to diagnose this condition, especially when it occurs in concomitance with preexisting spinal canal stenosis. We report our patient, a 48 year old male, who initially presented to our spine clinic with acute onset unilateral lower limb weakness associated with urinary retention, which was suspected to be cauda equina syndrome due to a prolapsed intervertebral disc.

Spine Surg Relat Res 2021 9;5(2):91-97. Epub 2020 Oct 9.

Department of Orthopaedic Surgery, Capital Corps of Republic of Korea Army, Yongin, Korea.

Lumbar Spinal Canal Stenosis from the Perspective of Locomotive Syndrome and Metabolic Syndrome: A Narrative Review.

Nobuyuki Fujita

Spine Surg Relat Res 2021 20;5(2):61-67. Epub 2020 Aug 20.

Department of Orthopaedic Surgery, School of Medicine, Fujita Health University, Aichi, Japan.

Patients with lumbar spinal canal stenosis (LSS) have impaired activities of daily living because of pain or motor paralysis, but no effective preventive treatment is currently available. The number of patients with LSS is predicted to continually increase as the average age of the global population increases. To provide a conceptual framework for improving healthy life expectancy, the Japanese Orthopaedic Association introduced the concept of locomotive syndrome, to which LSS is related. Read More

Minimally invasive tubular laminectomies in multilevel spine surgery-an illustrative case-based review of techniques and combined approaches.

J Spine Surg 2021 Mar;7(1):83-99

Section of Neurosurgery, Cleveland Clinic Indian River Hospital, Vero Beach, FL, USA.

Minimally invasive techniques have become part of the spine surgeons' armamentarium and are currently utilized to treat many conditions involving the cervical, thoracic, lumbar and sacral spine. Surgical treatment of severe degenerative conditions such as multilevel spinal stenosis, tandem stenosis, combination of stenosis or disk herniation and spondylolisthesis at adjacent spinal levels, as well as extensive infections or hematomas, may require a multilevel tailored approach with all the challenges that such surgical planning entails. Although the use of minimally invasive tubular decompressive procedures has gained widespread popularity in the recent years, the adoption of such techniques during multilevel spine surgery can be at times challenging.

A Technical Nuance to Avoid Lumbar Five Radiculopathy with Anterior Lumbar Fusion and Posterior Instrumentation.

Case Rep Orthop 2021 24;2021:5514720. Epub 2021 Mar 24.

Department of Neurologic Surgery, Mayo Clinic College of Medicine and Science, 5777 East Mayo Boulevard, Phoenix, AZ 85054, USA.

The anterior lumbar interbody fusion (ALIF) is a well-established procedure used to treat a multitude of spinal pathologies. When performed at the L5-S1 level, the ALIF is often supplemented with posterior pedicle screw and rod fixation. Because the interbody device can restore disk and foraminal height, one benefit of the ALIF procedure is indirect neural decompression in the spinal canal and neural foramina. Read More

Foramen Magnum Dural Arteriovenous Fistula Presenting With Thoracic Myelopathy: Technical Case Report With 2-Dimensional Operative Video.

Oper Neurosurg (Hagerstown) 2021 Apr 7. Epub 2021 Apr 7.

Background And Importance: Dural arteriovenous fistulas (dAVFs) are vascular abnormalities of the central nervous system that can cause a wide array of neurological dysfunction depending on their location, flow, and propensity to rupture. Symptomatic dAVFs at the cranio-cervical junction usually result in hemorrhage or cervical myelopathy. Distantly located dAVFs of the foramen magnum are a rare cause of thoracic intrinsic myelopathy.

Late-week surgery and discharge to specialty care associated with higher costs and longer lengths of stay after elective lumbar laminectomy.

J Neurosurg Spine 2021 Apr 6:1-7. Epub 2021 Apr 6.

2Department of Neurosurgery, Cleveland Clinic, Cleveland; and.

Objective: In a healthcare landscape in which costs increasingly matter, the authors sought to distinguish among the clinical and nonclinical drivers of patient length of stay (LOS) in the hospital following elective lumbar laminectomy-a common spinal surgery that may be reimbursed using bundled payments-and to understand their relationships with patient outcomes and costs.

Methods: Patients ≥ 18 years of age undergoing laminectomy surgery for degenerative lumbar spinal stenosis within the Cleveland Clinic health system between March 1, 2016, and February 1, 2019, were included in this analysis. Generalized linear modeling was used to assess the relationships between the day of surgery, patient discharge disposition, and hospital LOS, while adjusting for underlying patient health risks and other nonclinical factors, including the hospital surgery site and health insurance.

The Scoliosis Research Society adult spinal deformity standard outcome set.

Spine Deform 2021 Apr 6. Epub 2021 Apr 6.

Department of Orthopedic Surgery, Norton Leatherman Spine Center, University of Louisville, Louisville, KY, USA.

Purpose: Symptomatic adult spinal deformity (ASD) with an extremely variable presentation with pain, with and without neurogenic leg pain, and/or disturbed sagittal and coronal balance, causes a significant societal burden of disease. It is an important consequence of the aging adult population, generating a plethora of spine-related interventions with variable treatment efficacy and consistently high costs. Recent years have witnessed more than a threefold increase in the prevalence and treatment of ASD, and further increases over the coming decades are expected with the growing elderly population worldwide.
