BackgroundPlatelet-rich plasma (PRP) has been found to be effective for a variety of musculoskeletal conditions. The treatment of discogenic pain with PRP is under investigation.ObjectiveTo assess changes in pain and function in patients with discogenic low back pain after an intradiscal injection of PRP.Study DesignProspective trial.MethodsPatients were diagnosed with discogenic low back pain by clinical means, imaging, and exclusion of other structures. Provocation discography was used in a minority of the patients. Patients underwent a single treatment of intradiscal injection of PRP at one or multiple levels.Main Outcome MeasuresPatients were considered a categorical success if they achieved at least 50% improvement in the visual analog score and 30% decrease in the Oswestry Disability Index at 1, 2, and 6 months post-treatment.Results22 patients underwent intradiscal PRP. Nine patients underwent a single level injection, ten at 2 levels, two at 3 levels, and one at 5 levels. Categorical success rates were as follows: 1 month: 3/22 = 14% (95% CI 0% to 28%), 2 months: 7/22 = 32% (95% CI 12% to 51%), 6 months: 9/19 = 47% (95% CI 25% to 70%).ConclusionThis trial demonstrates encouraging preliminary 6 month findings, using strict categorical success criteria, for intradiscal PRP as a treatment for presumed discogenic low back pain. Randomized placebo controlled trials are needed to further evaluate the efficacy of this treatment.© 2015 American Academy of Pain Medicine. All rights reserved.
