MRI Morphology of Surgically Treated Lumbar Canal Stenosis

Abstract

LCS seems to produce predictable patterns on T2 axial MRI. The triangular configuration correlates most frequently with surgical LCS. Further studies are needed in normal individuals, in prospective patients, and to determine the outcome of treatment based on MRI morphology.

Psychosocial Factors in Patients Indicated for Lumbar Spinal Stenosis Surgery

“…43 None of the quantitative parameters measured on X-rays, computed tomography scans, or magnetic resonance imaging (MRI) correlates well with the severity of clinical symptoms in lumbar canal stenosis. 44 The LSS Outcome Study Working Group with 41 musculoskeletal and neuroradiologists recently published the results of their Delphi survey, 45 where they concluded that none of the quantitative parameters was uniformly acceptable for the diagnosis of lumbar canal stenosis and only some of the quantitative parameters were partially accepted. Lumbar canal stenosis seems to produce predictable patterns on T2 axial MRI.…”

“…Further studies are needed in prospective patients and in normal individuals to determine the outcome of treatment based on MRI morphology. 44 Substantial evidence in the literature indicates that at > 65 years of age, degenerative changes in the intervertebral disk, facet joints, and osteophytes can contribute to the development of radiologic or pathologic evidence of spinal canal narrowing in 80 to 100% of the population. [46][47][48] However, the clinical incidence of spinal stenosis in the United States has only been calculated as between 3% and 14%.…”

“…49,50 This suggests that a large percentage of the population with pathologic changes of degeneration in the spine are actually asymptomatic. 44 Evaluation of pain and disability by the patient becomes more important and increasingly is used more than evaluation by surgeons and other professionals. 51,52 Functional aspects of the disease and the patient's quality of life are rather more significant.…”

Efficacy of the Clinical-Instrumental Algorithm in the Treatment of Spinal Tandem Stenosis

“…4,10,15 Neuroimaging techniques have significantly expanded the diagnostic capabilities for early verification of degenerative spinal diseases, which in turn, has led to an increase in the number of surgical interventions for spinal stenosis. 16,17 However, certain difficulties still remain in diagnosing the disease and choosing objective indications for surgery. The criteria for comparison of clinical neurological symptoms and pathomorphological compression factors of combined tandem stenosis, which are visualized by radiographic techniques, are not fully presented.…”

Multicenter Analysis of Surgical Treatment Effectiveness for Patients With Symptomatic Tandem Stenosis of the Cervical and Lumbar Spine Based on Differentiated Clinical-Instrumental Algorithm

“…клиническая комплексная оценка неврологической симптоматики, непосредственно зависящей от степени сужения позвоночного канала и межпозвонкового отверстия при сочетанных тандем-стенозах, определяет выбор оперативного вмешательства [4,10,15]. нейровизуализационные методы исследования значительно расширили диагностические возможности ранней верификации дегенеративных заболеваний позвоночника, что определило тенденцию к увеличению числа хирургических вмешательств по поводу стенозов позвоночного канала [16,17].…”
