ObjectivesTo assess the incidence of complications of fluoroscopically guided lumbar transforaminal epidural injections.DesignA retrospective cohort design study. Patients presenting with radiculopathy, caused by either lumbar spinal stenosis or herniated nucleus pulposus confirmed by magnetic resonance imaging or computed tomography scanning, received transforaminal epidural steroid injections as part of a conservative care treatment plan.SettingA multidisciplinary spine care center.InterventionAll injections were performed consecutively over a 4-month period by five physiatrists. An independent observer reviewed medical charts, which included a 24-hour postprocedure telephone call by an ambulatory surgery center nurse who had asked a standardized questionnaire about complications following the injections. Physician follow-up office notes 1 to 3 weeks after the injection, along with epiduragrams, were also reviewed.ResultsTwo hundred seven patients who received 322 injections were reviewed. Complications per injection seen included 10 transient nonpositional headaches that resolved within 24 hours (3.1%), 8 increased back pain (2.4%), 2 increased leg pain (0.6%), 4 facial flushing (1.2%), 1 vasovagal reaction (0.3%), 1 increased blood sugar (258 mg/dL) in an insulin-dependent diabetic (0.3%), and 1 intraoperative hypertension (0.3%). No dural punctures occurred.ConclusionsThere were no major complications. The incidence of minor complications was 9.6% per injection. All reactions resolved without morbidity, and no patient required hospitalization.
