There are many causes of pain after osteotomy and orthopedic surgery for old lumbar vertebral fracture, such as postoperative scar adhesion, damage to the vertebral plate and nerves, and unstandardized rehabilitation treatment. 1. Postoperative scar adhesion: After osteotomy and orthopedic surgery for old lumbar vertebral fracture, there is no suitable exercise, which will lead to slow local blood circulation and promote adhesion of muscles, fascia and other tissues, so that the activity will involve the adhesive tissues and cause pain. 2. Damage to the vertebral plate and nerves: In the process of surgery, the structure of the vertebral plate and the surrounding nerve structure may be accidentally damaged, resulting in abnormal nerve conduction, which may cause pain inside the fracture after surgery. 3. Unstandardized rehabilitation treatment: After the surgery, the failure to carry out appropriate exercise and physical therapy according to the condition of the patient may lead to delayed healing of the fracture, muscle adhesion, etc., which in turn may cause pain inside the fracture. When there is obvious pain inside the old lumbar vertebral fracture after osteotomy and orthopedic surgery, it is necessary to go to the hospital in time to find out the cause of the disease.
