The CT results suggest that there is a herniated lumbar 5 sacral 1 disc, and there is calcification of the herniated disc tissue, and generally speaking, the possibility of retraction is very small. However, a herniated lumbar disc is not the same as having “lumbar disc herniation”. The key is to see whether there is pressure on the nerve root of sacral 1 and whether there are symptoms and signs of nerve root pressure, such as lumbosacral pain with radiating pain and numbness in the lower limbs, etc. The diagnosis of the disease requires that the symptoms, signs and imaging coincide. “Slight compression of the anterior border of the corresponding dural sac” usually does not cause obvious symptoms, and based on this point alone, “lumbar 5-sacral 1 disc herniation” cannot be diagnosed. However, it should be reminded that the diagnosis rate of lumbar spine CT is only 80% and there is a blind spot. If there is a high clinical suspicion, lumbar spine magnetic resonance examination is needed if necessary. Pay attention to avoid sedentary, bending, weight-bearing, feasible lumbar back muscle function exercise (such as backward walking, swimming, etc.), do not smoke (can accelerate the degeneration of the intervertebral disc).
