Evolving role of VIADISC for chronic low back and discogenic pain: a narrative review.

Introduction: Chronic lower back pain is a leading cause of disability and healthcare spending worldwide. Discogenic pain, pain originating from the intervertebral disk, is a common etiology of chronic lower back pain. Currently, accepted treatments for chronic discogenic pain focus only on the management of symptoms, such as pain. There are no approved treatments that stop or reverse degenerating intervertebral discs. Biologic therapies promoting disc regeneration have been developed to expand treatment options. VIADISC™ NP, is a viable disc allograft supplementation that, in a recent trial, demonstrated a significant reduction in pain and increased function in patients suffering from symptomatic degenerative disc disease.

Areas Covered: This manuscript summarizes the epidemiology and etiology of low back pain, the pathophysiology of degenerative disc disease, current treatments, and a need for newer therapies. The rationale behind intradiscal biologics for the treatment of symptomatic degenerative disc disease is also discussed.

Expert Opinion: Characterization of the biology leading to disc degeneration has allowed for the development of intradiscal biologics. They may soon be capable of preventing and reversing disc degeneration. Clinical trials have shown promise, but further research into efficacy and safety is needed before these therapies are widely employed.
