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 .
Lumbar Total Disc Replacement Using ProDisc II: A Prospective Study With a 2-Year Minimum Follow-up
A lumbar total disc replacement ( TDR ) is believed to be a promising substitute in the surgical treatment for lumbar degenerative disc disease . The purpose of this study is to report the clinical and radiographic outcomes of 36 consecutive patients who underwent lumbar TDR using ProDisc II  , and the factors associated with a better clinical outcome after a 2-year minimum follow-up . At the time of the latest follow-up , the success rate was 94 % of 36 patients according to the criteria of the US Food and Drug Administration . Of the 10 patients unable to work preoperatively , 7 patients returned to work . Moreover , mean score on the visual analog scale for low back and leg pain improved significantly from 7.5 and 4.7 to 3.0 and 1.2 , respectively ( P<0.001 ) . In addition , mean Oswestry disability index scores improved significantly from 69.2 to 21.0 ( P<0.001 ) . Mean disc height at the operative level increased significantly from 9.0 to 17.6 mm , and mean range of motion increased significantly from 9.7 to 12.7 degrees ( P<0.01 ) . Statistical analysis showed that the factors associated with a better clinical outcome were single level , and a higher postoperative segmental ROM at the operative level . At a minimum follow-up of 2 years , the lumbar TDR using ProDisc II showed excellent clinical and radiographic outcomes without any significant complication . However , future efforts need to be directed toward the evaluation of a larger number of patients with longer follow-up
