Quantitative analysis of bone cement dispersion height in percutaneous vertebroplasty and kyphoplasty and comparison of therapeutic effects

Both PVP and PKP can significantly improve pain and other symptoms and improve the prognosis of patients with osteoporotic vertebral compression fracture.The PVP procedure has significant advantages in terms of operation time, frequency of intraoperative imaging monitoring, and volume of cement infusion. However, the PKP group was superior in terms of postoperative vertebral body height recovery, control of cement leakage, improvement of visual analog score (VAS) for pain, and recovery of Oswestry dysfunction index (ODI). The latest study further found that the three-dimensional dispersion height of the cement in the vertebral body and its percentage of the vertebral body volume can be used as a potential imaging predictor to evaluate the efficacy of the two surgical procedures, which provides a new reference dimension for the selection of the clinical surgical procedures and prognosis assessment.
