Spinal Stenosis Prevalence and Association with Symptoms: The Framingham Study

Abstract

Background Context-The prevalence of lumbar spinal stenosis (LSS) in the general population and association with low back pain (LBP) remains unclear. Purpose-1) to evaluate the prevalence of congenital and acquired LSS observed on computed tomography (CT) in a community-based sample; 2) to evaluate the association between LSS and LBP. Study design/Setting-Cross-sectional observational study. This study was an ancillary project to the Framingham Heart Study. Sample-3529 participants underwent multi-detector CT. 191 were enrolled in this study. Self-report Measures-LBP in the preceding 12 months was evaluated using a self-report questionnaire. Physiologic Measures-LSS (congenital and acquired) was characterized using two cutpoints: 12 mm for relative LSS, and 10 mm for absolute LSS. Methods-Using multiple logistic regression we examined the association between LSS and LBP, adjusting for sex, age and BMI. Results-In the congenital group, relative LSS was found in 4.7% and absolute LSS in 2.6% of patients. Acquired LSS was found in 22.5% and in 7.3%, respectively. Acquired LSS showed increasing prevalence with age: <40 years, the prevalence of relative and absolute LSS was 20.0% and 4.0%, respectively; in those 60-69 years the prevalence was 47.2% and 19.4%, respectively. The presence of absolute LSS was associated with LBP with an odds ratio of 3.16 (95% CI: 1.05-9.53).

Changes in paraspinal muscles and their association with low back pain and spinal degeneration: CT study

“…The data about prevalence of spinal degeneration features in this studied sample and their association with LBP were previously published [24,26,27]. Although we were only able to identify a significant relationship between multifidus density and spondylolisthesis when we used the summative measure from the principle component analysis, when data were considered separately for each level we identified an association between muscle density of multifidus and/or erector spinae at a specific lumbar level and FJOA, disc narrowing, and spondylolisthesis and related levels.…”

Effectiveness of Surgery for Lumbar Stenosis and Degenerative Spondylolisthesis in the Octogenarian Population

“…Lumbar stenosis and degenerative spondylolisthesis affect the aging population. A 2009 study using computed tomography found that 47% of individuals at least sixty years of age had lumbar spinal stenosis 2 . The number of surgical procedures for lumbar degenerative disease performed in the elderly, particularly spinal arthrodesis procedures, has increased substantially over the previous decade 3 .…”

Электромиографическое Исследование Биоэлектрической Активности Мышц Нижних Конечностей У Пациентов С Дегенеративным Стенозом, Осложненным Синдромом Нейрогенной Перемежающейся Хромоты

“…По результатам когор-тного исследования, проведенного в Швеции (2009) и включающего 10 494 человека, ежегодное число опера-ций по поводу стеноза позвоночного канала на уровне поясничного отдела позвоночника составляет 9,7 на 100 тысяч населения. Причем в последние годы коли-чество операций по поводу поясничных стенозов еже-годно увеличивается на 4,7-13,2 % [10].…”

“…При центральном стенозе, как правило, наблю-дается компрессия корешков «конского хвоста», ко-торая клинически проявляется симптомокомплексом компрессионной полирадикуло(миело)ишемии (на-блюдается боль в поясничной области, иррадиирую-щая в нижние конечности, гипостезия кожи нижних конечностей, нейрогенная перемежающаяся хромота (НПХ)). Латеральный и центральный стеноз пояснич-ного отдела позвоночника в 20-30 % случаев сущест-вуют одновременно, вследствие чего возникает сме-шанная форма [6,10].…”
