ObjectiveTo determine the effectiveness of cervical transforaminal injection of steroids (CTFIS) and to explore possible determinants of response in patients with cervical disc herniation.DesignRetrospective practice audit covering a time period of 6 months.SettingSingle spine center in which the patients underwent CTFIS, surgery, and subsequent treatment. Magnetic resonance images were reviewed independently by a radiologist and two neurosurgeons.InterventionsConsecutive patients with cervical radicular pain and a magnetic resonance imaging demonstrating nerve root affection received CTFIS. Evaluation in terms of pain reduction and in relation to the level and side of the affected nerve root, the duration of pain, neck or radicular pain, and the presence of sensory or motor deficits. The radiological features assessed were the location, grading, and cause of the impingement.ResultsForty-eight patients were included. Only 35.4% of patients achieved at least 50% reduction in pain 1 month after treatment. The initial pain on the numeric rating scale was reduced from 6.8 to 1.8. None of the clinical or radiological features was associated with a successful outcome. 22.9% of the included patients had to undergo an operation. The duration of these patients' symptoms was significantly shorter (P = 0.01) than in patients without operation.ConclusionOnly a minority of patients with disc herniation or spondylosis and a proven nerve root compression benefits from CTFIS. The potential advantage for the patient must be compared with the risk of the procedure. Even with the combination of clinical and radiological findings, the prediction of a favorable outcome of CTFIS was not possible.Wiley Periodicals, Inc.
