Long term clinical and MRI follow-up of 76 patients after synovial cyst resection via microscopic hemilaminectomy: a retrospective study

Treatment of synovial cysts by microscopic hemilaminectomy yields acceptable long-term results. Preoperative spondylolisthesis appears to affect postoperative ODI, instability and spondylolisthesis but not the reoperation rate or cyst recurrence. No other independent variable appeared to affect dependent variables.
