摘要
ObjectiveTo determine the effectiveness and safety of computerized tomography (CT) guided, lumbar transforaminal injection of steroids in the treatment of radicular pain. %26lt;br%26gt;DesignSystematic review of published literature. %26lt;br%26gt;InterventionsTwo reviewers independently assessed 19 publications on the effectiveness and safety of CT-guided, lumbar transforaminal injection of steroids. %26lt;br%26gt;Outcome MeasuresFor effectiveness, the primary outcome was the success rate for relief of pain. For safety, the radiation exposure involved and the nature of complications were determined. %26lt;br%26gt;ResultsMuch of the literature fails to provide evidence. Two studies reported decreases in mean or median pain scores but no other data. Two studies reported success rates of between 34% and 62% for achieving 50% relief of pain at between 1 and 6 months after treatment. CT-guided injections may involve greater radiation exposure than does fluoroscopy-guided injections and do not avoid catastrophic spinal cord injury. %26lt;br%26gt;ConclusionThe evidence-base for CT-guided lumbar transforaminal injection of steroids is meagre. This intervention is not more effective than fluoroscopy-guided injections and is not demonstrably safer.
