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

Popis výsledku v původním jazyce

Introduction: Synovial cysts can be treated by several non-instrumented surgical techniques, which are commonly grouped into non-homogenous cohorts. Few studies have analyzed surgical results of synovial cyst resection via microscopic hemilaminectomy with adequate imaging and long-term follow-up. Research question: What is the long-term rate of reoperation, synovial cyst recurrence, new instability, listhesis progression, new synovial cysts in unoperated segments and postoperative patient function after synovial cyst resection via microscopic hemilaminectomy? Materials and methods: Seventy-six patients who underwent synovial cyst resection by microscopic hemilaminectomy were analyzed via a postoperative MRI, dynamic radiographs, clinical examination and Oswestry Disability Index (ODI). Dependent variables were rate of reoperation, new instability, listhesis progression, cyst recurrence, postoperative patient function and new stenosis/synovial cysts in unoperated segments. They were plotted against independent variables including age, intervertebral disc degeneration, indirect signs of instability and surgical invasiveness. Results: Reoperation was performed in 10 cases after a mean period of 71.3 months. Cyst recurrence occurred in 4 cases, new instability in 21 cases and listhesis progression in 37 cases. New synovial cysts and stenosis occurred in 6 and 9 cases respectively and 63 patients reported a postoperative ODI &lt;= 40. Preoperative spondylolisthesis was associated with listhesis progression, new instability, higher postoperative ODI and new stenosis. Discussion and conclusion: Treatment of synovial cysts by microscopic hemilaminectomy yields acceptable longterm 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.
