Facet cysts – also known as synovial cysts – are fluid-filled sacs located in the joints of the spine, most commonly in the lumbar section. They typically develop as a result of age-related degeneration of the spine.
Symptoms vary depending on the size and location of the cyst but generally include back or leg pain that worsens when standing and walking as well as numbness, tingling, or weakness in one or both legs. Facet cysts may also cause sciatica, which would likely present as pain in one or both legs which typically radiates to the foot.
Dr. Reddy’s typical treatment plan includes removing the cyst and decompressing the spinal cord and nerves. After removing the cyst, he may also need to fuse the joint to prevent the cyst from reoccurring and prevent any further instability of the affected joint.
