Not being able to straighten up more than 2 months after lumbar spine surgery may be caused by scar tissue formation or local adhesion, and some patients with lumbar spine fracture surgery will take about 3 months to return to normal life. 1. Lumbar spine fracture surgery: If vertebroplasty is used, most of the fracture and post-surgical symptoms will be significantly relieved in about 3 days after the surgery, and the patient can slightly move down to the ground while wearing a rigid lumbar brace, and can return to normal life in about 3 months. In the case of middle-aged or elderly patients, the postoperative recovery time will be relatively later. After surgery, you need to insist on monthly checkups. 2. Lumbar disc herniation: If open and large incision internal fixation is used, the recovery time will take about 2~3 months, and the activities need to be appropriately restricted after the operation, and generally it can return to normal in 6 months. In case of minimally invasive laminectomy, the patient can walk on the ground on the second day and return to normal life in about 2 months. 3. Poor postoperative recovery: Generally after surgery, there will be fibrous connective tissue proliferation at the fracture injury for scar repair, the proliferation of fibrous connective tissue may lead to local adhesions, while the formation of the scar if it is too large will also affect the normal function of the vertebrae. The recovery time for lumbar spine surgery is related to the patient’s condition, the surgical method and the method of rehabilitation. It is important to follow the doctor’s instructions before and after the surgery, and actively rehabilitate the patient to avoid any other abnormalities. If there is any discomfort, it is recommended to consult your doctor.
