Oper Neurosurg (Hagerstown) 2019 Mar;16(3):391

Hospital Italiano de Buenos Aires, Capital Federal, Argentina.

Neurogenic claudication is a common symptom of lumbar spinal stenosis; its pathophysiology is thought to be ischemia of the nerve roots secondary to compression from surrounding structures. The stenosis of the lateral recesses and neuroforamen can cause these symptoms and its surgical treatment is decompression. The placement of interbody cages that restore the disc space height may indirectly decompress the neuroforamen and alleviate the nerve impingement symptoms. Read More

2nd Radiology Department, Medical School, University General Hospital "ATTIKON", National and Kapodistrian University of Athens, 1 Rimini str, 12462, Haidari/Athens, Greece.

Vertebral compression fractures (VCFs) may result in a kyphotic deformity which can cause potential systemic complications secondary to respiratory and gastrointestinal dysfunction. The use of implants in the spine for VCF treatment represents a paradigm shift away from cement injection on its own, aiming to combine the analgesic and stabilizing effect of injecting cement into the vertebral body with vertebral height restoration and kyphotic angle correction. Spine implants which can be used for VCF treatment include stents, jacks, PEEK cages and fracture reduction systems. Read More

We tested if this neuromodulation technique affects the F-wave conduction on both sides to explore the underlying physiologic mechanisms.

Methods: We studied a total of 26 LSS patients, assigning 16 to a study group receiving repetitive tibial nerve stimulation at the ankle (RTNS) on one leg, and 10 to a group without RTNS. Read More

Characteristics and determinants of clinical symptoms in radiographic lumbar spinal stenosis in a tertiary health care centre in sub-Saharan Africa.

BMC Musculoskelet Disord 2017 Nov 28;18(1):494. Epub 2017 Nov 28.

Faculty of medicine and Biomedical Sciences, University of Yaounde I, Yaoundé, Cameroon.

Background: Lumbar spinal stenosis (LSS) refers to narrowing of the lumbar central spinal canal, lateral recess, and/or neuro-foramina. Radiographic LSS plays an important role in clinical LSS but is not solely accountable for the presence of symptoms. We sought to characterise clinical LSS and to determine factors associated with presence of symptoms of LSS in patients with radiographic LSS in a sub Saharan Africa setting. Read More

Effectiveness of a Decision-Making Protocol for the Surgical Treatment of Lumbar Stenosis with Grade 1 Degenerative Spondylolisthesis.

World Neurosurg 2018 Feb 10;110:e355-e361. Epub 2017 Nov 10.

Department of Neurosurgery, Bergman Clinics, Amsterdam, The Netherlands.

Background: Addition of fusion to decompression for stenosis with grade 1 degenerative spondylolisthesis is a controversial topic, and the question remains if fusion provides any benefit to the patient that warrants the increased health care utilization and perioperative morbidity. There is no consensus on indications for use of fusion over decompression alone.

Methods: Patients received fusion or decompression according to a decision-making protocol based on their pattern of complaints, location of the compression, and facet angles and effusion as proven predictors of postoperative instability. Read More

Nursing review of diagnosis and treatment of lumbar degenerative spondylolisthesis.

Surg Neurol Int 2017 10;8:246. Epub 2017 Oct 10.

NYU Winthrop Hospital, Mineola, New York, USA.

Background: In the lumbar spine, degenerative spondylolisthesis or degenerative (not traumatic) slippage of one vertebral body over another is divided into 4 grades - grade I (25%), grade II (50%), grade III (75%), and grade IV (100%). Dynamic X-rays, magnetic resonance (MR), and computed tomography (CT) scans document the slip secondary to arthritic changes of the facet joint plus stenosis, ossification of the yellow ligament, disc herniations, and synovial cysts. MR best demonstrates soft tissue pathology whereas CT better delineates ossific/calcified disease. Read More

Clinical classification criteria for neurogenic claudication caused by lumbar spinal stenosis. The N-CLASS criteria.

Spine J 2018 06 12;18(6):941-947. Epub 2017 Oct 12.

Division of General Internal Medicine, Massachusetts General Hospital, 50 Stanifort Street, Room 966, MA 02114, Boston, USA.

Background Context: Because imaging findings of lumbar spinal stenosis (LSS) may not be associated with symptoms, clinical classification criteria based on patient symptoms and physical examination findings are needed.

Purpose: The objective of this study was to develop clinical classification criteria that identify patients with neurogenic claudication (NC) caused by LSS.

Study Design: This study is a two-stage process that includes Phase 1, the Delphi process, and Phase 2, the cross-sectional study. Read More

Spine Conditions: Lumbar Spinal Stenosis.

FP Essent 2017 Oct;461:21-25

Virginia Commonwealth University Fairfax Family Medicine Sports Medicine Fellowship, 3650 Joseph Siewick Drive Suite 400, Fairfax, VA 22033.

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. Read More

Baastrup's Disease, Interspinal Bursitis, and Dorsal Epidural Cysts: Radiologic Evaluation and Impact on Treatment Options.

Cureus 2017 Jul 9;9(7):e1449. Epub 2017 Jul 9.

Miami Neurosurgical Center, University of Miami Hospital.

Baastrup's disease or "kissing spines syndrome" was first described as a cause of lumbar pain before computerized tomography (CT) and magnetic resonance imaging (MRI) scanning existed. The diagnosis was based on x-ray studies, which showed that the spinous processes, especially in the lower lumbar spine, became approximated to each other and this was a generator of positional back pain. Biomechanically, the interspinous and supraspinous ligaments that are degenerated in Baastrup's disease normally contribute significantly to sagittal alignment. Read More

Nursing Review Section of Surgical Neurology International Part 2: Lumbar Spinal Stenosis.

Surg Neurol Int 2017 7;8:139. Epub 2017 Jul 7.

NYU Winthrop Hospital, NYU Winthrop NeuroScience, Mineola, USA.

Background: The lumbar spine includes 5 lumbar vertebral bodies, L1, L2, L3, L4, and L5. At each level, there is a disc space defined by the two bones (vertebral bodies) in the back; for example, there is a disc space at the L5-S1 level etc. The normal front to back (anterior to posterior or AP diameter) measurement of the spinal canal is typically 18-20 mm, but some patients have narrowing called spinal stenosis.

Targeted Radiofrequency Ablation as an Adjunct in Treatment of Lumbar Facet Cysts.

Cureus 2017 Jun 6;9(6):e1318. Epub 2017 Jun 6.

Miami Neurosurgical Center, University of Miami Hospital.

Lumbar facet cysts are frequently found in patients with facet degeneration and segmental instability. When the facet cyst is localized in the neural foramina and lateral recess or becomes large, it can cause radiculopathy or neurogenic claudication. These symptomatic cysts are typically treated interventionally with drainage and a corticosteroid injection or attempts via overinflation to rupture the cyst; however, these procedures have a significant recurrence rate (up to 50%) and often need to be repeated or lead to lumbar surgery if unsuccessful.
