Abstract:
Lumbar disc prolapse is one of the common causes of low back pain seen in the working population. There are contradictory reports regarding the clinical significance of various magnetic resonance imaging (MRI) findings observed in these patients.Objective : To find out the correlation of clinical features and magnetic resonance imaging (MRI) findings in determining the level of lumbar disc herniation.Patients and Methods : This study was conducted in department of radiology Baghdad teaching hospital from15thaugust 2013 to 15th august 2014 , the total number of patients with prolapse intervertebral disc was 100, the clinical level of disc herniation was determined depending on clinical findings (dermatomal distribution, pin - prick test , SLR Test , knee reflex And Ankle reflex ) and correlated with MRI findings (direction and location of disc herniation and nerve root compression).For both data entry and data analysis Statistical package for social science version 18 (SPSS18) was used. P - value of < 0.05 considered significant.11AbstractResults : Total 100 patients were studied during the12 months period. Out of 100 patient (52%) were male while (48%)were female. Age range was from 17 - 70 years, mean age was 38.9 ±11.4 .Maximum patients were in the age group range from17 - 34 (37%) followed by 35 - 45 years (33%).The duration of symptoms was ranging from 2 months to 2 years. The duration of symptoms was less than 1 year in 57% of patients and while 43% in 1 - 2 years group. The average duration in female patients was 1.1 years and in male patients was 11.23 monthon MRI the commonest nerve compression grade was grade 1 (contact) , when we comparing clinical test grade with nerve compression grade it was found that clinical test grade show very strong association with nerve compression grade .on MRI most disc herniation direction was posterolateral (61%)and (39%)central direction , when we test if there is association between the direction of disc herniation and whether there is nerve root compression we found strong relationship with p - value equal 0.003 .The level of disc herniation was determined on clinical basis as well as on MRI. These findings were compared and correlated for single level disc like L4 - L5 and L5 - S1 and for multiple levels. We found out the sensitivity, specificity and predictive values of clinical features and applied chi square test.In case of L4 - L5 level disc herniation, the sensitivity of all clinical features was 70.5% and positive predictive value was 80%, while the specificity was12Abstract62.5% and negative predictive value was 50%. The chi square value was significant with P value of 0.001.In case of L5 - S1 level disc herniation, the sensitivity and specificity of clinical features as a whole were 71.7% and 62% respectively. The positive predictive value was 55% and negative predictive value was 77.5% with significant chi square test of P value of 0.001.In case of L4 - L5 &L5 - S1 levels disc herniations the sensitivity and specificity of clinical features as a whole were 43% and 91.05% respectively. The positive predictive value and negative predictive value were 27% and 95.5% respectively with significant chi square test of P value of 0.028.Conclusion : This study shows that the lower lumbar discs are affected more than other disc site. In addition, there are strong association between nerve compression grade with severity of symptoms and signs so as the grade increase so also symptoms and signs increase.Also we found strong relationship between the direction of herniation and nerve root compression, so the posterolateral herniation direction compress root more often than central one .Finally, the clinical features should be correlated with MRI findings in determining the level of disc herniation. There is excellent correlation between the clinical features and MRI findings in case of single and multiple level disc herniation, when it is lying posterolaterally at L4 - L5 level or L5 - S1 level.
