Abstract

BACKGROUND:

Percutaneous kyphoplasty and percutaneous vertebroplasty are effective safe minimally invasive treatment methods for osteoporotic vertebral compression fracture. Percutaneous kyphoplasty has a certain advantage on long-period pain release, incidence rate of bone cement leakage, vertebral height recovery, and long-term kyphotic angle reduction compared with percutaneous vertebroplasty. However, we cannot deny the effects of percutaneous vertebroplasty in the treatment of osteoporotic vertebral compression fracture.

OBJECTIVE:

A meta-analysis was performed to assess the safety and efficacy of percutaneous kyphoplasty and percutaneous vertebroplasty for treating osteoporotic vertebral compression fractures.

METHODS:

A systematic computer-based search of all studies published till May 2013 was conducted in PubMed, Web of science, Ovid medline, Embase, Cochrane central database and CNKI for controlled studies concerning percutaneous kyphoplasty and percutaneous vertebroplasty in treatment of osteoporotic vertebral criteria. Meta analysis was performed using Revman5.2 (5.2.5 edition) software provided by Cochrane Collaboration.

RESULTS AND CONCLUSION:

A total of 12 studies containing 1 081 patients were included. The results of meta-analysis indicated that there were no significant differences between the two groups in the short-term pain relief, short-term and long-term Oswestry Dability Index scores, incidence of adjacent-level fracture, short-term restoration of kyphosis angle and operation time (P > 0.05). However, there were significant differences in the long-term pain relief, the incidence of cement leakage, postoperative anterior vertebral heights and long-term restoration of kyphosis angle (P < 0.05). Results suggested that percutaneous kyphoplasty was superior to percutaneous vertebroplasty in the long-term pain relief, the incidence of cement leakage, restoration of postoperative anterior vertebral body and long-term restoration of kyphosis angle. Percutaneous kyphoplasty and percutaneous vertebroplasty both are safe and effective surgical procedures. Due to lack of high-quality randomized controlled trails in the original studies, more randomized controlled trails are required and a prudent choice is suggested.
