BackgroundSpinal synovial cysts are a known cause of back pain and radiculopathy. With the advent of high-resolution imaging techniques, synovial cysts are increasingly diagnosed. There are a variety of treatment options for these lesions.MethodsA systematic literature review of published articles reporting outcomes after nonsurgical and surgical management of spinal synovial cysts was performed.ResultsThere were 51 published studies regarding the treatment of synovial cysts identified. Treatment modalities include observation, steroid injections, percutaneous cyst aspiration, hemilaminectomy or bilateral laminectomy with and without instrumented fusion, and minimally invasive cyst excision.ConclusionsBased on review of the treatment modalities and outcomes, recommendations for the management of patients with synovial cysts are proposed. Observation can be considered in cases where there is no intractable pain. High-risk surgical patients with intractable pain may consider corticosteroid injection or percutaneous cyst aspiration; however, the failure rate of such a procedure approaches 50%. Patients with intractable pain are candidates for surgical resection of the symptomatic cyst. In cases of significant neurologic deficit, motor weakness, back pain, multiple synovial cysts, or spondylolisthesis, bilateral laminectomy and instrumented fusion may offer the best long-term outcome.Copyright © 2013 Elsevier Inc.
