The main indications for the use of bone cement injection are the occurrence of lumbar compression fractures and the absence of symptoms of nerve damage. The price of bone cement is not clinically clear and depends on the origin of the bone cement and the amount of bone cement used. If a compression fracture of one vertebra of the lumbar spine occurs, the price is about 20,000-22,000 RMB if the bone cement is infused by vertebroplasty and the bone cement is domestically produced, and the price will be slightly higher if the bone cement is imported. If an infection occurs after the artificial joint replacement, the cost of removing the prosthesis for bone cement shaping is about 23,000-25,000 yuan, which may vary from region to region and from hospital to hospital.
