Comparison of the clinical effects of percutaneous vertebroplasty and percutaneous kyphoplasty in the treatment of osteoporotic vertebral compression fractures

Abstract

Objective To investigate the effect and safety of percutaneous vertebroplasty(PVP) and percutaneous kyphoplasty(PKP) in the treatment of osteoporotic vertebral compression fractures, thus to provide reference for clinical treatment. Methods 67 patients with osteoporotic vertebral compression fractures were selected as study subjects.According to the different operation type, the patients were divided into PVP group(n=32) and PKP group(n=35). The operation condition, pain degree, relative height of vertebral body, Cobb angle and incidence of cement leakage were compared between the two groups. Results The operation time, X-ray times, bone cement injection volume, postoperative injury vertebral height of the PKP group were significantly higher than those of the PVP group(all P 0.05). Conclusion PVP and PKP are the effective methods for the treatment of osteoporotic vertebral compression fractures, which can significantly improve the degree of pain in patients, but PKP surgery is more conducive to promote the restoration of vertebral height, and can reduce the occurrence of bone cement leakage.
