Percutaneous vertebroplasty Percutaneous vertebroplasty is a minimally invasive spinal surgery technique that involves percutaneous injection of bone cement into the vertebral body through the vertebral arch or outside the vertebral arch to increase the strength and stability of the vertebral body, prevent collapse, relieve pain, and even partially restore the height of the vertebral body. Indications: vertebral body tumor or osteoporotic compression fracture 1. treatment of vertebral body tumor Mainly: vertebral body hemangioma/myeloma/vertebral body primary and metastatic malignant tumor/partial vertebral body benign tumor. Absolute contraindications: uncorrected coagulation disorders and bleeding body; Relative contraindications: (1) radicular pain and significantly more pain than the vertebral body, caused by a compression syndrome unrelated to vertebral body collapse; (2) tumor extension into the epidural space and causing significant spinal canal compression; (3) osteogenic tumors; 2. Treatment of patients with osteoporotic vertebral body fractures. Detailed as follows: Indications: (1) painful osteoporotic vertebral compression fractures that are ineffective with drug therapy; (2) painful vertebral fractures associated with osteonecrosis; (3) unstable compression fractures; (4) multiple osteoporotic vertebral compression fractures resulting in posterior convexity deformity and causing pulmonary function, gastrointestinal function and altered center of gravity; (5) acute traumatic fractures without neurological symptoms. Absolute contraindications: (1) Patients with poor general condition; (2) Uncorrected coagulation disorders and bleeding constitution. (3) Patients with signs of nerve compression (4) Allergy to any of the items required for the procedure. Relative contraindications: (1) pain of a radicular nature and significantly exceeding the pain of the vertebral body, caused by a compression syndrome unrelated to vertebral body collapse; (2) severe vertebral body collapse; (3) patients with rupture of the posterior wall of the vertebral body
