Long-term effectiveness of transforaminal anterolateral approach CT-guided cervical epidural steroid injections for cervical radiculopathy treatment

• Aim: To evaluate the long-term clinical effectiveness of computed tomography (CT)-guided transforaminal cervical epidural steroid injection using an anterolateral approach for the treatment of cervical radiculopathy (CR) using well-established robust clinical scoring systems for neck pain and neck disability. Despite its widespread use, evidence to support the long-term benefit of routine cervical epidural steroid injection is currently very limited.Materials and methods: This study included 113 patients with magnetic resonance imaging (MRI)-confirmed CR who underwent a steroid injection at a single cervical level via a unilateral transforaminal anterolateral approach. Pain was assessed quantitatively at pre-injection, 15 minutes post-injection, 1 month, 3 months, and at 1 year. Neck disability was assessed using the Oswestry Neck Disability Index (NDI) at pre-injection, 1 month, 3 months, and 1 year time points.Results: Eighty patients completed the study. Sixty per cent reported reduced neck pain (mean pain reduction, 55%), which was clinically significant in 45% cases. Furthermore, 66% reported an improvement in neck disability (mean improvement, 51%), which was clinically significant for 56% patients. Clinically significant good outcomes in both neck pain and neck disability were evident from as early as 1-month, and importantly, were independent both of pre-treatment CR characteristics (including severity of pre-injection neck pain or disability) and of findings on pre-injection MRI imaging.Conclusion: Transforaminal anterolateral approach CT-guided epidural steroid injection resulted in a clinically significant long-term improvement in both neck pain and disability for half of the present cohort of patients with unilateral single-level CR. This improvement was independent of the severity of the initial symptoms and pre-injection MRI findings.
