Question
How is a synovial cyst formed?
Answer
The patient reported falling from a ladder 2 meters high, landing on their left hip, and inquired about the causes of synovial cysts. The doctor recommended a CT or MRI scan of the lumbar intervertebral disc to determine if the condition is a synovial cyst or due to other reasons causing lower limb symptoms, such as sciatica compression. Sciatica compression may cause symptoms like a heavy feeling in the lower limb, pain, or numbness, usually due to a lumbar intervertebral disc herniation or bulging compressing the sciatic nerve. The doctor can initially determine if there is sciatica compression through straight leg raising and strengthening tests, and decide whether further examination is needed.
