Intradiscal Injection of Platelet-rich Plasma for Discogenic Pain in L-spine

Intervertebral disc (IVD) degeneration is an important clinical problem that often contributes to low back pain and degenerative disc diseases. Degeneration of the IVD induces anulus tears and fissures, which can cause severe discogenic low back pain. Because the IVD has little potential to self-regenerate, treatment of degenerative disc disease is one of the most challenging clinical problems facing the spine surgeon. Platelet-rich plasma (PRP) is a fraction of plasma that contains platelets and multiple growth factors concentrated at high level. Because activated platelets have the potential to release growth factors, PRP has been clinically used to accelerate wound healing and tissue regeneration in orthopedic and oral surgery. The soluble releasate isolated from PRP has recently been demonstrated to influence the metabolism of intervertebral discs in vitro. Furthermore, an intradiscal injection of autologous PRP has been shown to induce restoration of structural changes in the rabbit annular injection model in vivo. This clinical trial aims to investigate the safety and efficacy of intradiscal PRP injection in patients with discogenic low back pain. The pre- and post-interventional imaging and clinical outcomes will be compared.
