AbstractRecent reports of provocative discography not only instill confusion, but also create numerous questions about its value in evaluating low back pain. It was reported that provocative discography produced pain in patients who were not suffering with low back pain but suffering with somatization disorder and depression. This study was designed to evaluate 50 randomly assigned patients, with 25 patients in Group I without somatization disorder and 25 patients in Group II with diagnosis of somatization disorder. In addition, depression, generalized anxiety disorder and combinations thereof were also evaluated. All patients underwent discography, investigating two to three discs in each patient. All studies included a control level with a disc that did not produce the patient's pain upon injection of contrast medium. Provocation with exact pain reproduction concordant with the symptom complex upon injection of contrast into the disc was considered positive. Any other response, with or without pain, was considered negative. Results showed positive provocative discography in 46% of the patients in the somatization group compared to 54% in the non-somatization group; in 46% of patients with depression compared to 54% of patients without depression; in 15 of 30 patients with generalized anxiety disorder; in 11 of 20 patients without generalized anxiety disorder; and in 42% of patients with combined somatization and depression, with negative discography in 58% of the patients. It is concluded that provocative discography provides similar results in patients with or without somatization, with or without depression, with somatization but with or without depression or with other combinations of the psychological triad of somatization disorder, depression, and generalized anxiety disorder.
