AbstractThis study was designed to determine the prevalence of lumbar facet joint pain in patients suffering with or without somatization disorder. The study was performed using comparative local anesthetic blocks. One hundred consecutive patients with chronic low back pain, with or without somatization, were evaluated. The results showed that, among patients suffering with chronic low back pain, 44% of the patients without somatization and 38% of the patients with somatization were positive for facet joint pain. The diagnosis of facet joint pain was not influenced by the presence or absence of somatization disorder. The evaluation also was extended to depression, generalized anxiety disorder and combinations with or without somatization thereof which showed no significant differences in the prevalence of facet joint pain. The results of this study demonstrated that the facet joint was a source of pain in chronic low back pain patients in 44% of the patients without somatization and 38% of the patients with somatization. This study also showed that there was no correlation between the presence or absence of facet joint pain and the presence or absence of somatization disorder or any other psychological condition or combination thereof.
