Lumbar spine fracture 5 months walking back drop may be due to the nerve damage has not recovered, nerve tissue adhesion, lumbar spine mobility reduced, bedridden, etc., the patient needs to consult the doctor in time to clarify the cause of the disease. 1. Neurological factors: preoperative nerve injury or postoperative nerve tissue adhesion can damage the lumbar spine nerves, and a feeling of falling down in the waist may occur when walking. (1) Unrecovered nerve damage: After nerve damage caused by lumbar spine fracture, the recovery of nerve damage is slow. After lumbar spine surgery, only the nerve compression is lifted, but the damaged nerves cannot be repaired, so it is normal to feel a drooping sensation in the waist when walking 5 months after lumbar spine surgery. (2) Post-operative nerve tissue adhesion: Lumbar spine surgery sometimes needs to expose the nerve tissue, which may pull the nerves during the surgery, and there may be oozing after the surgery, resulting in adhesion of the nerve tissue, which may also manifest as the symptoms of lumbar drop. 2. Surgery and bed rest: lumbar spine surgery sometimes requires vertebral fusion, resulting in reduced mobility of the lumbar spine and stiffness of the surrounding muscles, which is manifested as a feeling of lumbar drop; after surgery, when patients are bed-ridden, lack of lumbar movement or lack of early rehabilitation training can also cause lumbar muscle stiffness, and even lumbar drop when walking. In addition to the above factors, lumbar vertebrae fracture 5 months after walking back drop may also be related to cold, postoperative activities, etc., it is recommended that patients seek medical attention in a timely manner, to identify the cause of the disease, under the guidance of the doctor to carry out targeted treatment, so as to avoid delaying the condition.
