Adhesions after minimally invasive surgery for a herniated lumbar disc can be infused. Adhesions after minimally invasive surgery for herniated lumbar discs are usually due to the exposure of the dura mater at the surgical site after removal of the nerve roots and laminae, and may cause symptoms of numbness and pain in the lower extremities. The presence of adhesions is usually followed by a fluid infusion, which is usually administered with medications such as hyaluronic acid, chitosan, and polylactic acid for symptomatic relief. After minimally invasive surgery for lumbar disc herniation, it is necessary to pay attention to keep warm, avoid catching cold, need to lie down in a hard bed to rest, should not go down to the ground too early to avoid repeated bending or twisting of the waist, so as not to induce lumbar disc protrusion symptoms. Patients can train straight leg raising according to their own situation when lying in hard bed rest, which can reduce the possibility of local adhesion. Patients with lumbar disc protrusion should observe the body condition after the operation, and if any abnormality occurs, they should go to the hospital in time to avoid any adverse consequences.
