AbstractEvaluation of the age related prevalence of persistent low back pain has been estimated to be consistently higher in the elderly compared to the younger population. Facet joints have been shown to be the cause of chronic low back pain in 15% to 45% of the patients in controlled studies. Prevalence of facet joint mediated pain has not been studied in the elderly. The study population consisted of 100 patients. Group I consisted of 50 patients that were 64 years of age or younger. Group II consisted of 50 patients 65 years of age or older. The patients were randomly allocated into 1 of the 2 groups. Facet joints were investigated with diagnostic blocks initially using lidocaine 1% followed by bupivacaine 0.25%, usually 2 weeks apart. The prevalence of facet joint mediated pain was determined to be 30% in the adults and 52% in the elderly, which was significantly higher with a false positive rate of 26% in adults and 33% in the elderly. In conclusion, the results of this study show that facet joint mediated pain is a significant problem in all patients suffering with chronic low back pain with the prevalence of 52% in the elderly and 30% in adults.
