“…In contrast to our analysis the four studies 3,6,7,18 included in the systematic review assessed only up to three different MRI parameters with various clinical outcomes. The results of our study support the results of at least two of the earlier studies 3,6 whereas the other two studies found no strong associations.…”

“…2 To the present, the relationship between abnormal magnetic resonance imaging (MRI) findings and pain is still debated. [3][4][5][6][7] It has been shown that symptoms often poorly correlate with radiologic findings. 4 Ishimoto et al 8 reported that a substantial number of asymptomatic persons showed a moderate or even severe narrowing of the spinal canal (defined as more than ⅓ or ⅔ area loss respectively) in the MRI.…”

(2016). Is there an association between pain and magnetic resonance imaging parameters in patients with lumbar spinal stenosis? Spine, 41(17) : AbstractStudy design: Prospective multi-center cohort study.Objective: To identify an association between pain and magnetic resonance imaging (MRI) parameters in patients with lumbar spinal stenosis (LSS). Summary of Background Data:To the present, the relationship between abnormal MRI findings and pain in patients with LSS is still unclear.Methods: First we conducted a systematic literature search. We identified relationships of relevant MRI parameters and pain in patients with LSS. Second, we addressed the study question with a thorough descriptive and graphical analysis to establish a relationship between MRI parameters and pain using data of the lumbar spinal stenosis outcome study (LSOS).Results: In the systematic review including four papers about the associations between radiological findings in the MRI and pain, the authors of two articles reported no association and two of them did. Of the latters, only one study found a moderate correlation between leg pain measured by Visual Analogue Scale (VAS) and the degree of stenosis assessed by spine surgeons. In the data of the LSOS study we could not identify a relevant association between any of the MRI parameters and buttock, leg and back pain, quantified by the Spinal Stenosis Measure (SSM) and the Numeric Rating Scale (NRS). Even by restricting the analysis to the level of the lumbar spine with the most prominent radiological 'stenosis' no relevant association could be shown. Conclusion:Despite a thorough analysis of the data we were not able to prove any correlation between radiological findings (MRI) and the severity of pain. There is a need for innovative 'methods/techniques' to learn more about the causal relationship between radiological findings and the patients' pain related complaints.

Muscle Strength During Active Straight Leg Raising Correlates with Walking Capacity in Patients with Lumbar Spinal Canal Stenosis with Neurogenic Intermittent Claudication

Abstract.[Purpose] The purpose of this study was to investigate the factors related to walking capacity (WC) reflecting neurogenic intermittent claudication (IC). [Subjects and Methods] We selected 56 female patients (69.6 ± 8.0 years) with Lumber Spinal Canal Stenosis (LCS) with IC. We measured WC on a flat floor, and demonstrated that 3 factors predict the relationship with IC as follows: trunk forward bending in the standing position (finger-floor distance), muscle strength during active straight leg raising (ASLR) on the symptomatic side, and the degree of subjective pain soon after standing upright for 30 s.[Results] WC and muscle strength in ASLR were not affected by age. WC was correlated with ASLR strength.[Conclusion] These results suggest that the motion of ASLR leads to canal or foraminal stenosis, and that this test will be useful for patients with LCS.

“…However the narrow lumbar canal would result from the fact that the size of the dural sac is inadequate to that of the lumbar canal. According to the studies of Geisser et al [15], in normal conditions, there is an empty space between the lumbar canal and its content, enabling free movement of the content, without tension or pressure during movement of the lumbar spine. An abnormal reduction of this empty space between the lumbar canal and its content would be the cause of the nervous suffering.…”

Objective: To determine through CT scan, the biometrics of the spinal canal and lumbar dural sac of adults in Togo. Material and method: Twelve month prospective study at Campus Teaching Hospital and Sylvanus Olympio Univesristy Hopsital Center, concerning people over 18 years of age who presented neither any clinical sign nor spinal defect. Distances measured were the antero posterior diameter (APD1) and inner pedicular diameter (IPD) of the lumbar canal, the antero posterior diameter (APD2) and transverse diameter (TD) of the dural sac, followed by the evaluation of APD2/APD1 (R1) and TD/IPD (R2) ratio. Results: The mean age was 38+/9.34 years. The general average APD of the lumbar canal (APD1) was 15.41±0.55mm, with a minimal average of 10.48±0.57mm and a maximal average of 25.00±2.60mm. The general average IPD was 23.27±1.67mm, with a minimal average of 13.68±1.46mm and a maximal average of 33.68±1.46mm. The average APD of the dural sac (APD2) was 11.60±0.66mm, with a minimal average of 10.7±0.66mm and a maximal average of 10.7±0.66mm. The average TD of the dural sac was 15.55±1.54mm, with a minimal average of 14.03±2.43mm and a maximal average of 17.63±1.82mm. The evaluation of the ratio ADP2/ADP1 (R1) found general average R1 of 0.80±0.04, with a minimal average R1 of 0.76±0.06 and a maximal average R1 of 0.85±0.07. The ratio TD/IPD (R2) found an average R2 of 0.69±0.14, with a minimal average of 0.5±0.12 and a maximal average of 0.84±0.08. Conclusion:The diameters of the lumbar canal and dural sac in Togo do not differ significantly from those described in the literature.

Spinal Canal Size and Clinical Symptoms Among Persons Diagnosed With Lumbar Spinal Stenosis

Abstract: AP spinal canal diameter is not predictive of clinical symptoms associated with LSS. The findings also suggest that body mass may play a significant role in functional limitations observed in this population.
