  • Title: Radicular pain in post lumbar surgery syndrome: the significance of transforaminal injection of steroids.
    Author: Klessinger S.
    Journal: Pain Med; 2013 Feb; 14(2):243-6. PubMed ID: 22882468.
    Abstract:
    OBJECTIVE: The objective of the study was to see if transforaminal injection of steroids might be an effective treatment for persistent radicular pain after disc surgery. DESIGN: The study was designed as a retrospective practice audit covering a time period of 2 years. SETTING: The study was set in a single spine center in which all patients underwent lumbar disc surgery, postoperative follow-up, and subsequent treatment. INTERVENTIONS: Patients with postsurgical radicular pain were treated with a transforaminal injection of a steroid. The effect was evaluated in terms of pain reduction, duration of pain relief, and in relation to a recurrent disc herniation in postperative magnetic resonance imaging. RESULTS: Of 479 patients who underwent microsurgical lumbar disc surgery, 69 had persistent radicular pain. Transforaminal injection of steroid achieved pain reduction of at least 50% in 26.8% of these patients. The success rate was higher (43%) in patients without a recurrent disc herniation. CONCLUSIONS: Transforaminal injection of steroid appears to be effective in only a minority of patients with radicular pain persisting after disc surgery, but is more often effective in patients without recurrent disc herniation.
