19 Οκτ 2021 · When the cyst starts to grow, it can put pressure on a nearby nerve. Symptoms can be very similar to sciatica or spinal stenosis: lower back pain, leg pain or even leg weakness. Treatment options include both surgical and non-surgical methods.
The most reliable treatment method for a synovial cyst is to remove the cyst and then fuse the joint. Fusing the joint stops all the motion at that level of the spine, and without any motion, the cyst should not regenerate.
Treatment modalities include observation, steroid injections, percutaneous cyst aspiration, hemilaminectomy or bilateral laminectomy with and without instrumented fusion, and minimally invasive cyst excision.
Synovial cysts are most often caused by age-related degeneration. They are most common in patients older than 65 years. Synovial fluid, contained in a membrane called the synovial sac, lubricates the facet joints and helps them move smoothly.
Treatment for synovial cysts that cause symptomatic lumbar stenosis, the treatment is largely the same as for other causes of lumbar spinal stenosis, with the exception that there is often accompanying spinal instability at the same joint that needs to be considered if surgery becomes necessary.
The fluid-filled sac creates pressure inside the spinal canal that compresses the nerves and causes pain. The best treatment for synovial cysts is generally non-surgical care, including over-the-counter pain medications, activity modification, and injections.
