Abstract
Lumbar spine synovial cysts develop from degenerated zygapophyseal joints. Symptomatic patients present with radicular pain and weakness or neurogenic claudication.1 In the absence of significant concomitant degenerative spondylolisthesis, symptomatic patients can be managed with a laminectomy and microsurgical resection of the cyst, without the need for instrumented fusion.2,3 In this video, we present the microsurgical resection of a left-sided L4-5 synovial cyst in a 68-yr-old man with radicular pain refractory to conservative management. The radiographical features, relevant surgical anatomy, and salient operative steps are reviewed, and strategies for preventing cyst recurrence are emphasized. There were no complications, the postoperative course was unremarkable, and the patient was discharged on postoperative day 1 with significant improvement in his presenting symptoms. No identifying information is present, and patient consent was obtained for the procedure and for publishing the material included in this video.
