Vertebroplasty versus Kyphoplasty in the Treatment of Osteoporotic Vertebral Compression Fractures: A Meta-Analysis

One of the most frequent consequences of osteoporosis is osteoporotic vertebral compression fractures, which makes it one of the most prevalent health care crises in the world. Two things are needed to manage them: 1) pain management, and 2) fracture stabilization. To take care of both, 2 methods are commonly used: 1) vertebroplasty and 2) kyphoplasty (KP) without a clear consensus on which is the better one. A meta-analysis was done comparing both techniques in the management of osteoporotic vertebral compression fractures.PubMed, Cochrane, and Google Scholar (page 1-20) were searched updated to October 2022. Two reviewers determined the eligibility of the studies independently. Only 8 studies were included in the meta-analysis. The clinical outcomes consisted of the complications (cement leakage, adjacent level fractures), the visual analog scale scores, Oswestry disability index, kyphotic wedge angle, and vertebral body height restoration.KP was shown to be superior to vertebroplasty in terms of reducing cement leakage, and increasing postoperative vertebral body height. The comparison of the rest of the outcomes was statistically insignificant between both techniques.Although KP could significantly increase postoperative vertebral body height and decrease the risk of cement leakage, the fact that it is more costly and has a longer operative time raises the question about the cost effectiveness of the procedure.
