Objective: To identify the relationship of the quantitativesize of disc herniation and canal compromise with the clinicalsymptoms and physical findings.
Method: Twenty-fourpatients, who were diagnosed as having a single-level lumbarradiculopathy caused by intervertebral disc herniation,were retrospectively evaluated for this study. The clinicalsymptoms included the presence of accompanying backpain and pain intensity expressed as a numeric rating scalescore and physical examinations consisted of Dejerine’s triad,straight-leg raise (SLR) test, slump test, Kemp’s test,and evaluation of motor and sensory involvement. The sizeof disc herniation and canal compromise (%) were calculatedby the quantitative image analysis of T2-weighted axialimages.
Results: The size of disc herniation showed a significantcorrelation with the SLR test (p＜.001) and motorpower grade (p=.002). The canal compromise also showeda significant correlation with the SLR test (p＜.001) and motorpower grade (p=.002). Other variables did not show anycorrelation with the size of disc herniation and canal compromise.
Conclusion: Quantitative size of disc herniationand canal compromise were correlated with motor weaknessand SLR angles in patients with lumbar radiculopathy.(Clinical Pain 2014;13:84-93)
