Comparison of Efficacy of Percutaneous Vertebroplasty versus Percutaneous Kyphoplasty in the Treatment of Osteoporotic Vertebral Asymmetric Compression Fracture

This study aims to compare the clinical efficacy of percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral asymmetric compression fracture (OVACF). This study retrospectively reviewed the patients who were diagnosed with OVACF between September 2015 and July 2019. Forty-one patients received PVP surgery (group A), and 44 patients received PKP surgery (group B). The visual analog scale, Oswestry Disability Index, scoliosis angle (SA), height of long side, height of short side (HS), and lateral height difference (LHD) before operation and 3 days and 1 year after operation were compared between both groups. The operation time, fluoroscopic time, hospital stay, cement volume, and complications were also compared between both groups. The visual analog scale and Oswestry Disability Index differed significantly between the groups 1 year after operation (P < 0.05). Compared with the preoperative results, there were significant differences in SA, height of long side, HS, and LHD 3 days and 1 year after operation (P < 0.05). Compared with group A, group B showed significantly better in SA, HS, and LHD in group B 3 days and 1 year after operation (P < 0.05). More patients in group A suffered cement leakage and scoliosis than group B after operation (P < 0.05). In our study, PVP and PKP are both effective in the treatment of OVACF, but PKP surgery had better long-term clinical efficacy.
