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 .
Four-Year Follow-up Results of Lumbar Spine Arthrodesis Using the Bagby and Kuslich Lumbar Fusion Cage
Study Design . This was a prospect i ve multicenter clinical trial of a lumbar interbody fusion cage with a minimum of 4 years ’ follow-up . Objectives . To determine whether the early positive clinical results in fusions with lumbar cages , such as the Bagby and Kuslich ( BAK ) cage , are maintained beyond 2 years . Summary of Background Data . Threaded cages have been used increasingly for the treatment of symptomatic degenerative intervertebral disc disease . Concerns about the long-term clinical outcomes of this procedure have been posed , particularly regarding bony fusion viability , revision rates , potential adjacent level disease , and late complications . Methods . The study cohort was a 196-patient subset from a prospect i ve investigational device exemption . In addition to early postoperative examinations , these patients were examined biannually with a minimum of 4 years ’ follow-up . Patient outcome was assessed by a 6-point scale that evaluated pain relief , and functional improvement was determined by changes in activities of daily living . Fusion rates and return to work were determined . Complications and secondary operations were reported and categorized as non – device related or device related . Results . The patient cohort with 4-year follow-up represented 25.6 % of the original study population eligible at that time . Overall , the largest percentage of pain relief and functional improvements occurred by 3 months , and these improvements were maintained at each follow-up . Overall fusion rate was 91.7 % and 95.1 % at 2 and 4 years , respectively . In this cohort , 39.5 % of patients were working or were able to work within 3 months of surgery . After 4 years , 62.7 % of patients were gainfully employed or able to work . The late-occurring complication rate in this cohort was 13.8 % ( 27/196 ) . Complications necessitating a second operation occurred in 8.7 % ( 17/196 ) , whereas reoperations that were deemed device related were performed in 3.1 % ( 6/196 ) . Conclusions . This study indicates that the early positive benefits of interbody fusion cage procedures are maintained through 4 years with acceptably low morbidity
