RESULTS The results of this review confirm and help quantify the significant differences that existed in the terminology and all the areas of diagnosis and treatment of presumed discogenic pain .
Our findings show that suspected discogenic pain , despite its extensive affirmation in the literature and enormous re sources regularly devoted to it , currently lacks clear diagnostic criteria and uniform treatment or terminology
BACKGROUND CONTEXT Pain innate to intervertebral disc , often referred to as discogenic pain , is suspected by some authors to be the major source of chronic low back and neck pain .
Current management of suspected discogenic pain lacks st and ardized diagnosis , treatment , and terminology .
PURPOSE In an attempt to determine whether patterns existed that may facilitate st and ardization of care , we sought to analyze the terminologies used and the various modes of diagnosis and treatment of suspected discogenic pain .
Randomized Controlled Trial of Percutaneous Intradiscal Radiofrequency Thermocoagulation for Chronic Discogenic Back Pain: Lack of Effect From a 90-Second 70 C Lesion
Study Design . A prospect i ve double-blind r and omized trial in 28 patients . Objectives . To assess the clinical effect of percutaneous intradiscal radiofrequency thermocoagulation for reducing pain , functional disability , and physical impairment in patients with chronic discogenic low back pain . Summary of Background Data . Chronic discogenic low back pain is a challenging problem in western countries . A treatment option is radiofrequency heating of the affected disc . Its clinical efficacy has never been formally tested in a controlled trial . Methods . Twenty-eight patients with a history of at least 1 year of chronic low back pain were selected on the basis of a diagnostic anesthetization of the lower intervertebral discs . Only patients with one putative painful level were selected and r and omly assigned to one of two treatment groups . Each patient in the radiofrequency treatment group ( n = 13 ) received a 90-second 70 C lesion of the intervertebral disc . Patients in the control group ( n = 15 ) underwent the same procedure , but without use of radiofrequency current . Both the treating physician and the patients were blinded to the group assignment . Before treatment , physical impairment , rating of pain , the degree of disability , and quality of life were assessed by a blinded investigator . Results . Eight weeks after treatment , there was one success in the radiofrequency group ( n = 13 ) and two in the control group ( n = 15 ) . The adjusted and unadjusted odds ratio was 0.5 and 1.1 , respectively ( not significant ) . Also , visual analog scores for pain , global perceived effect , and the Oswestry disability scale showed no differences between the two groups . Conclusions . Percutaneous intradiscal radiofrequency thermocoagulation ( 90 seconds , 70 C ) is not effective in reducing chronic discogenic low back pain
