The reason why there is buttock pain when the lumbar spine is slipped is that a slipped lumbar spine will cause compression of the nerves in the lumbar region. After the lumbar spine slipped, it will cause the effective volume of the spinal canal to become smaller, thus compressing the sciatic nerve, the innervation of the sciatic nerve, which is the lumbosacral region and both lower limbs. If the nerve is compressed to a certain degree, it will cause inflammatory changes such as degeneration and edema of the nerve, especially when the nerve is compressed to a very serious degree, and even urinary and fecal dysfunction will occur. Therefore, after the lumbar spine slipped, it will definitely cause nerve damage, and after the nerve damage, it will cause pain in its innervated area, and many patients will show pain in the buttocks, and at the same time, it is accompanied by pain and numbness in both lower limbs. The root cause of buttock pain in patients with lumbar spondylolisthesis is the compression of the nerve.
