Most cysts in the lumbar spine are seen in cysts in the lumbar spinal canal area, or in the nerve root canal. Two diseases, sacral canal cysts and nerve root sheath cysts, are more common in lumbar spine diseases. If the patient’s cyst in the lumbar spine grows outside the lumbar spinal canal, and he/she feels pain in the lumbar region, has local pressure pain and normal lumbar spine activities, he/she can first take conservative treatment, such as moxibustion and herbal fumigation, and instruct the patient to reduce the activities of the lumbar region and rest in bed. If the patient’s cyst occurs in the nerve root canal, repeated friction and degeneration of the cyst in the vertebral canal will be able to show symptoms of compression of the nerve, requiring surgical removal treatment. There are also cysts in the vertebral canal whose cause is less clear, and they also need to be treated by surgical excision. If the cyst occurs in the lumbar vertebral body is a bone cyst, it is a benign lesion. If the cyst is small and has no obvious symptoms, does not cause nerve compression and does not lead to sensory impairment, it does not require special treatment and only needs to be observed. If the cyst is large and causes nerve compression and sensory impairment, surgery to remove the cyst and bone grafting is required.
