Abstract:
objective To investigate the differences of percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP) during the perioperative period of osteoporotic vertebral compression fracture (OVCF). Methods Eighty-six cases of osteoporotic vertebral compression fractures were retrospectively analyzed, including 52 cases in the PVP group and 34 cases in the PKP group. The perioperative indexes (operation time, total amount of bone cement injection, postoperative vertebral growth height, postoperative VAS score) and follow-up indexes (vertebral anterior margin height, kyphoid Cobb Angle, vertebral compression rate) of the two groups were compared statistically. Result The operative time of PVP group was shorter than PKP group (37.3±8.1). The total amount of bone cement injected into the PVP group was less than PKP group (27.7±6.0), the height of postoperative vertebral injury increase in the PVP group(2.6±1.5) was less than PKP group(9.0±2.0), and the postoperative VAS score in the PVP group(2.4±0.4)was less than PKP group(1.9±0.2), with statistically significant differences (P<0.05). Postoperative comparison of the two groups of patients showed that the height of the anterior margin of the PVP group (19.85±2.16) was lower than that of the PKP group(24.18±3.07), the Cobb Angle of the posterior lobe of the PVP group (12.43±2.08) was greater than that of the PKP group(8.01±3.45), and the compression rate of the PVP group(24.89±5.52) was higher than that of the PKP group (20.23±3.49). Preoperative and postoperative comparison showed that the height of the anterior margin of the vertebral body was significantly increased, the Cobb Angle of the kyphoid and the compression rate of the vertebral body were significantly reduced in both groups (P<0.05). Conclusions PKP, compared with PKP, can further improve fracture repair of diseased OVCF vertebra, restore vertebral height as far as possible, and relieve postoperative pain. However, the operation time is long, the amount of bone cement injection is relatively large, and is not suitable for severe compression fracture.
