Vertebroplasty injects bone cement at the vertebral fracture to enhance vertebral strength and spinal stability. In this study, three-dimensional computerized tomography was used to track the shape and peripheral leakage of postoperative bone cement; the shape of the vertebral body was changed, the residual bone mass was changed, and the bone texture was changed. Patients who underwent computerized tomography after the hospital were collected, and the computerized tomography and post-processing workstations were used to observe whether the shape of the injected cement was cracked or rotated, and there was no leakage to the muscles or blood vessels or vertebral bodies. Shape and residual bone mass, and changes in bone texture. Postoperative image tracking revealed that some patients had bone cement leakage and volume reduction. The statistical results compare the correlation between fracture type, severity, endplate, bone cement loss volume, fracture site, bone cement volume and bone cement volume during surgery. The statistical results show that the fracture pattern and severity are significant. The score was 0.034 (p<0.05, two-tailed), the fracture pattern and endplate significance were 0.022 (p<0.05, two-tailed), and the volume of bone cement measured and the volume of bone cement injected during surgery were significantly less than 0.01 (p <0.01, two-tailed). In the vertebroplasty, the bone cement is much stronger than the osteoporotic bone. The general X-ray can only be traced. The computerized tomography can be used to evaluate the degree of bone cement filling in the vertebral body, giving clinicians a reliable data for postoperative management of patients.
