  • Title: Procedure-based nonsurgical management of lumbar zygapophyseal joint cyst-induced radicular pain.
    Author: Sabers SR, Ross SR, Grogg BE, Lauder TD.
    Journal: Arch Phys Med Rehabil; 2005 Sep; 86(9):1767-71. PubMed ID: 16181940.
    Abstract:
    OBJECTIVE: To evaluate the success of fluoroscopically guided, contrast-enhanced lumbar zygapophyseal joint (Z-joint) aspiration and steroid injection combined with transforaminal epidural steroid injections (TFESIs) for the treatment of lumbar Z-joint cyst-induced radicular pain. DESIGN: Retrospective case series with independent follow-up. SETTING: Institutional, referral center. PARTICIPANTS: Twenty-three patients referred to a single provider for procedure-based management of radicular pain believed secondary to lumbar Z-joint cyst. Inclusion criteria consisted of lumbar radicular pain that was consistent with the level and side of the Z-joint cyst as a causative lesion. INTERVENTIONS: Eighteen patients were treated with a fluoroscopically guided, contrast-enhanced Z-joint aspiration and steroid injection at the level of the causative cyst coupled with a fluoroscopically guided, contrast-enhanced TFESI over the level of the presumably irritated spinal nerve. MAIN OUTCOME MEASURES: Patient satisfaction, and whether or not surgery was performed. RESULTS: Fifty percent of patients treated with the procedure had significant long-term benefit and avoided surgical intervention at an average follow-up of 9.9 months. CONCLUSIONS: Fluoroscopically guided, contrast-enhanced spinal procedures as part of an aggressive nonsurgical treatment program are a safe and effective alternative to surgical intervention for lumbar Z-joint cyst-induced radicular pain.
