| Popis: | Background Lumbar synovial cysts (LSCs) are an uncommon cause of radiculopathy and back pain. Open surgical treatment is associated with extensive bone resection and muscle trauma. The endoscopic tubular–assisted LSC resection has not been described in detail. Here the authors assessed the effectiveness of this technique for LSC resection. Methods Eleven patients (4 female and 7 male patients) were operated on via an ipsilateral approach for resection of LSC using an endoscopic tubular retractor system. Preoperative magnetic resonance imaging was evaluated for signs of degeneration and instability. At follow-up a standardized questionnaire including the Oswestry Disability Index and functional outcome according to MacNab criteria was conducted. Additionally, a personal examination with particular reference to back and leg pain was performed. Results The mean follow-up was 10.5 months. Preoperatively, spondylolisthesis grade 1 was noted in 4 patients (36.4%). Ten patients had bilateral facet joint effusion (90.9%). At follow-up 10 patients reported being free of leg pain (90.9%), eight patients reported no back pain (72.7%), ten patients had full motor strength (90.9%), and 9 patients had no sensory deficit (81.8%). Nine patients reported an excellent or a good clinical outcome (81.8%). The mean Oswestry Disability Index was 4.7%. None of the patients developed new mechanical low back pain or required subsequent fusion procedure. Conclusion The endoscopic tubular–assisted procedure is a safe way to treat LSC. It offers complete resection of LSC and achieves good clinical outcome by preserving muscle and ligamentous and bony structures, which prevents delayed instability. |
