Currently, for old patients with vertebral compression fracture, vertebroplasty or kyphoplasty can be selected, and the bone cement materials commonly used at present are polymethyl methacrylate (PMMA) bone cement, calcium phosphate bone cement, calcium sulfate bone cement and the like, and the main purpose of the operation is to put semi-fluid bone cement into the fractured vertebral body and wait for the bone cement to solidify so as to achieve the supporting effect on the fractured vertebral body, but the following technical defects exist: 1) Because bone cement is in a semi-fluid state when being placed, the bone cement can be dispersed to other parts; 2) The PMMA bone cement can release a great amount of heat in the curing process, and can cause heat injury to surrounding tissues to cause inflammation and even cause tissue necrosis, the bone cement is dispersed to the surrounding tissues, and the released heat can cause injury to the tissues, such as injury to abdominal aorta and inferior vena cava in front of vertebral body, so that the patient is endangered by massive hemorrhage; dispersed into the vertebral canal, damage the caudal nerve and spinal cord of the horse, cause paralysis of the patient, etc.; 3) Because the curing time is long, the heat release in the curing process is relatively low, the adhesive force and strength of the calcium phosphate bone cement are relatively poor, and the calcium phosphate bone cement is easy to disintegrate from bone, so that the research of the calcium phosphate bone cement is still continued; because the calcium sulfate bone cement has poor biological activity, chemical bonds cannot be formed between the calcium sulfate implant and bone tissues, the calcium sulfate bone cement can be rapidly degraded, and the calcium sulfate bone cement can be completely absorbed within six weeks after being implanted into a body, and the rapid degradation condition is not matched with the bone formation process; 4) The setting time of the bone cement is short, and the bone cement is possibly hardened and cannot be put in after being put in a little later, so that additional bone cement is needed, and the cost of patients is increased; 5) The bone cement has high hardness and no elasticity after solidification, so that the stress of the adjacent segment vertebral bodies can be increased, and the bone cement is easy to fracture due to the osteoporosis of the old patients; 6) Due to the axial pressure, bone cement is easily extruded from the damaged position of the vertebral body and is displaced.
Therefore, how to design an implantation device of light-cured resin bone cement which is convenient for the bone cement in the vertebral body to be solidified, has certain elasticity after solidification, has smaller stress on the adjacent segment vertebral body and is not easy to cause the fracture of the adjacent segment vertebral body compared with the existing bone cement, and becomes the urgent problem to be solved.
