“…Lumbar stenosis is a degenerative disease resulting from the narrowing of the vertebral canal or the intervertebral foramina, which leads to compression of the nerve roots or the thecal sac. 1,2 It is estimated that 1.7% to 8% of the general population may present clinical symptoms, with increasing prevalence starting in the fifth decade of life and more frequent in the lumbosacral spine and in women. 1 Spondylarthrosis is the most common cause of lumbar spinal stenosis and usually affects individuals over the age of 60.…”

Objective: To evaluate degenerative lumbar stenosis in symptomatic patients submitted to surgeryand the correlation between probable determining factors. Methods: A retrospective descriptive study in which themagnetic resonance images of 73 patients with degenerative stenosis,who underwent surgeries involving 141 levels performed by a single surgeon at the Hospital Ortopédico de Passo Fundo from 2015 to 2018, were evaluated. The patients were stratified by the degree of facet tropism, facet arthrosis, disc degeneration, and operated side, as well as by epidemiological data such as age, sex, etc. Tropism was measured using the Karacan method and evaluated numerically and categorically. Disc degeneration was classified by Pfirrmann and facet arthrosis by Weishaupt. To analyze and obtain the results, the Chi-square test and ANOVA were used with the SPSS statistical program, version 18.0. Results: Statistical significance was found in the relationship between facet tropism and disc degeneration (p=0.026) at the L4-L5 level. No correlation was found between tropism and facet arthrosis (p=0.161) or tropism and the operated side (p=0.573). Conclusion: The degree of tropism directly influences disc degeneration and greater asymmetries are related to more severe degenerations. Although tropism has not shown a statistically significant correlation with the operated side (p=0.573), it is believed that further studies should be carried out on this correlation. Level of evidence II; Retrospective study.

“…Lumbar central spinal stenosis (LCSS) is defined as the narrowing of the lumbar spinal canal due to bulging intervertebral discs and/or hypertrophy of the ligamentum flavum and facet joints that results in the compression of nerve roots [1]. Being a degenerative process associated with age, it predominantly affects individuals older than 50 years [2]. Symptomatic LCSS affects approximately 27% of the general population and represents one of the leading causes of visits to pain clinics [3,4].…”

Purpose: The purpose of this study was to investigate the findings of electrodiagnostic studies (nerve conduction study (NCS) and electromyography (EMG)) in patients with moderate and severe lumbar central spinal stenosis (LCSS). Methods: We retrospectively reviewed the medical records of Ulsan University Hospital and identified 32 consecutive patients (mean age = 66.9 ± 7.4 years; male:female = 8:24) with LCSS. Based on the results of T2 axial magnetic resonance imaging at the level of L4–5, patients were categorized as having severe (n = 14) or moderate LCSS (n = 18). Results from NCS and EMG were retrieved. Additionally, we included 15 age- and sex-matched volunteers without LCSS (mean age = 65.2 ± 8.0 years; male:female = 4:11) to serve as a control group. Results of NCS and EMG were compared between the three groups. Results: We found that, compared to normal subjects, patients with moderate or severe LCSS presented significantly lower distal amplitudes of the compound motor action potential of both peroneal and tibial nerves. Regarding EMG, positive sharp waves and fibrillation potentials were exclusively observed in patients with severe LCSS group (28.6%). Conclusion: Electrodiagnostic studies were significantly altered in patients with moderate and severe LCSS. Our results may be helpful to diagnose LCSS-induced radiculopathy and to differentiate it from other causes of peripheral nerve pathologies.

“…The surgical indication for lumbar stenosis is still controversial, and the criteria are not always clear. More recent studies [4][5][6][7][8] question the real efficacy of the procedure, and whether the results significantly improve the quality of life of the patients. It is difficult to compare the improvement of patients objectively following surgery, given that even after considerable decompressions, some patients continue to present symptoms.…”

Objectives: To compare the clinical outcomes between patients with degenerative lumbar stenosis who were treated by decompression with those awaiting the same kind of treatment for the disease. Methods: Retrospective study which divided patients with degenerative lumbar stenosis with surgical indication in 2 groups, operated and awaiting the procedure. The Oswestry Disability Index (ODI) questionnaire, visual analog scale and SF36 were applied. Results: Twelve operated patients and 18 awaiting the procedure were included. The average age of those operated was 59 years (43-70), and 55 (37-82) (p=0.3) for those awaiting surgery. The operated group had a mean ODI of 38.67 against 59.72 (p<0.05) in the non-operated group. The pain analog scale had lumbar result of 5.33 and pain radiating to the lower limbs of 3.83 in operated patients, against 6.78 (p>0.05) and 7.22 (p<0.05) in the awaiting surgery patients, respectively. As for the SF36 scale, functional capacity, limitations due to physical aspects and pain had an average score of 36.25, 19.58 and 21.67 in the operated group against 35.94, 27.50 and 32.61 in the awaiting group (p>0.05), respectively. Conclusion: The operated patients showed improvement of referred pain in the lower limbs (leg VAS) and improved function (Oswestry), however showed no significant change in quality of life according to SF36 scale and low back pain (lumbar VAS) were found. 55 (37-82) (p = 0,3). el grupo operado tuvo odi promedio de 38.67 contra 59.72 del grupo de espera (p < 0,05). la escala analógica del dolor lumbar tuvo resultado de 5,33 y el dolor que se irradia a las extremidades inferiores de 3,83 en los operados contra 6,78 (p > 0,05) y 7,22 (p < 0,05), respectivamente, en el grupo de espera de la cirugía. en cuanto a la escala sF-36, la capacidad funcional, las limitaciones debidas a aspectos físico y el dolor tuvieron puntuación media de 36,25, 19,58 y 21,67 en pacientes operados contra 35,94, 27,50 y 32,61, respectivamente, en los que esperan la cirugía (p > 0,05). conclusión: los pacientes operados mostraron una mejoría del dolor referido en las extremidades inferiores (eva de la pierna) y mejoría de la función (oswestry). sin embargo, no se observaron cambios significativos con respecto al dolor lumbar (eva lumbar) ni en la calidad de vida medida a través del cuestionario sF-36.
