CONCLUSION: Minimally invasive laminectomy is an effective first-line treatment for symptomatic lumbar synovial cysts and avoids the need for fusion in the majority of treated patients. 18% of our patients required a fusion over 46 months, suggesting that further studies are required to guide patient selection.

ABSTRACT
BACKGROUND: Lumbar synovial cysts (LSCs) can cause painful radiculopathy, sensory and/or motor deficits. Historically, first-line surgical treatment has been decompression with fusion. Recently, minimally invasive laminectomy without fusion has shown equal or superior results to traditional decompression and fusion methods.
OBJECTIVE: This study investigates the long-term efficacy of minimally invasive laminectomy without fusion in the treatment of LSC as it relates to the rate of subsequent fusion surgery.
METHODS: A retrospective review was performed over a 10-year period of patients undergoing minimally invasive laminectomy for symptomatic LSCs. The primary endpoint was the rate of revision surgery requiring fusion.
RESULTS: Eighty-five patients with symptomatic LSCs underwent minimally invasive laminectomy alone January 2010-August 2020 at our institution. The most common location was L4-5 (72%). Pre-operative imaging identified spondylolisthesis (grade 1) in 43 (57%) patients, none of which were unstable on available dynamic radiographs. Average procedure duration was 93 minutes, with 78% of patients discharged home on the same day of surgery. Over 46 months of mean follow-up, seventeen patients (20%) required nineteen revision operations. Of those, 16 were spinal fusions (17.6%). Median time to fusion surgery was 36 months. There were no identifiable risk factors on multivariate regression analysis that predicted the need for fusion.
CONCLUSION: Minimally invasive laminectomy is an effective first-line treatment for symptomatic lumbar synovial cysts and avoids the need for fusion in the majority of treated patients. 18% of our patients required a fusion over 46 months, suggesting that further studies are required to guide patient selection.
