In general, it is not recommended that patients with lumbar disc herniation sleep on their backs for 10 days after surgery. Lumbar disc herniation is a degenerative disease of the spine, which is mainly characterized by low back pain, sciatica, lower limb numbness and radiating pain. Drug treatment is ineffective or serious condition can take minimally invasive surgery and traditional open surgery and other surgical treatment. Minimally invasive surgery can choose spinal endoscopic disc nucleus pulposus removal, simple interlaminar window nucleus pulposus removal, etc., which has the characteristics of less trauma and facilitates the recovery, etc.; traditional open surgery: hemilaminectomy, total laminectomy, intervertebral fusion and other surgical procedures. According to the different surgical methods adopted, the recovery time of patients also varies. In the early stage of recovery from lumbar disc surgery, patients are advised to lie flat and avoid sitting for a long time. Sleeping on the stomach is not conducive to the maintenance of the physiological curvature of the lumbar spine (normally the lumbar spine protrudes toward the front of the body), increases the pressure on the lumbar spine, and is prone to cause a feeling of heavy pressure and re-stimulation of the nerves, and also prone to cause postoperative wound hematoma, which is not conducive to the recovery of the wound after the operation. Therefore, it is not recommended to sleep on the stomach for 10 days after surgery.
