Whether the lumbar vertebral fracture is recovered 75 days after surgery is mainly decided according to the severity of the patient’s injury. 75 days of minor fracture has usually been recovered; 75 days of patients with heavier injuries usually do not have a full recovery. 1. Normal situation: if the patient’s preoperative injury is relatively mild, just a simple lumbar vertebral fracture or a single segment involved, the patient himself has no underlying disease, and his age is relatively young, and the patient treated by minimally invasive surgical procedures, such as percutaneous cemented vertebroplasty, intervertebral foraminoscopy, etc., he can go down to the ground at an early stage, and will not be confined to bed without complications, and he will be able to recover basically in 75 days under normal circumstances. 2. Special cases: patients with heavy pre-operative injuries, such as lumbar burst fracture, involving multiple segments, patients with nerve damage, etc., can’t recover in 75 days. Because the complete healing of the fracture usually takes about 90 days, the bone quality is more stable; and nerve damage patients recover even slower, at least 3-6 months to improve, completely damaged patients, and even can not be recovered. Fracture recovery is also related to whether the patient is combined with diabetes, nutritional status and many other factors.
