Transforaminal injection of autologous platelet-rich plasma for lumbar disc herniation: A single-center prospective study in Vietnam.

OBJECTIVE: Lumbar radiculopathy is a major health problem, which often treated by neurosurgery or guided lumbar epidural steroids for pain relief. We used autologous Platelet Rich Plasma (PRP) as a novel pharmaceutical agent that has strongly emerged in recent years to treat patients of lumbar disc herniation. From that, we evaluated the efficacy of PRP via transforaminal route in treatment of radicular pain in patients with lumbar disc herniation. METHODS: Twenty-five patients were enrolled and injected with 4 ml of autologous platelet rich plasma under fluoroscopic guidance via transforaminal epidural injection into area of affected nerve root. They were followed using Visual Analogue Scale (VAS), Modified Oswestry Disability Index (ODI) and Straight Leg Raising Test (SLRT) for clinical assessment. RESULTS: Patients who received transforaminal injections with autologous PRP showed statistically significant improvements on all three evaluation tools (VAS, ODI, SLRT). The improvements were sustained over twelve-month follow-up and there were no associated complications. CONCLUSION: Transforaminal injection with autologous PRP helps patients relieve chronic pains and be able return to work. Besides, autologous PRP can be considered as a good alternative to epidural steroids in management of lumbar disc herniation.
