Objective: To evaluate the effectiveness of fluoroscopic transforaminal epidural steroid injections as a conservative treatment for patients with degenerative lumbar scoliosis and radiculopathy. Design: Retrospective follow-up study. Setting: Academic outpatient physiatric interventional spine practice. Participants: 62 patients with radiographic evidence of degenerative lumbar scoliosis and complaints of radiculopathy. Intervention: At least 1 fluoroscopic transforaminal epidural steroid injection. Main Outcome Measures: Numeric rating scale (NRS) for worst pain experienced, North American Spine Society (NASS) Satisfaction Scale, amount of pain medication used, and the Adapted Stucki Questionnaire (ASQ) to assess function and pain status. Results: We obtained follow-up on 52 (82.5%) of 61 included patients. We had an average follow-up time of 85.5 weeks (range, 20–152wk), and performed an average of 1.3 injections per patient. We defined a successful outcome as a patient who was both satisfied with his/her results and who experienced at least a 2-point improvement in NRS and ASQ summary pain and summary function scores. Using these criteria for success, 59.6% of our patients had a successful outcome at 1 week postinjection, 55.8% had a successful outcome at 1 month postinjection, 55.8% had a successful outcome at 1 month postinjection, 44.2% had a successful outcome at 3 months postinjection, 37.2% had a successful outcome at 1 year postinjection, and 27.3% had a successful outcome at 2 years postinjection ( P<.01). In addition, 14 (27%) of our patients had complete symptom relief for an average of 1.5 years. Conclusion: Fluoroscopic transforaminal epidural steroid injections are an effective nonsurgical treatment option for patients with degenerative lumbar scoliosis and radiculopathy and should be considered before surgical intervention.
