Comparison of therapeutic effect between percutaneous vertebroplasty and kyphoplasty on vertebral compression fracture

Objective:To compare the clinical efficacy of percutaneous vertebroplasty(PVP) with percutaneous kyphoplasty(PKP) in the treatment of vertebral compression fracture(VCF). Methods:Ninety-eight patients with VCF were treated by PVP(n = 42) or PKP(n = 56).The anterior midline and posterior heights of vertebrae body, preoperative and postoperative visual analogue scale (VAS),operation time and amount of blood loss were compared between 2 groups. Results:There was statistical difference in vertebral height between two groups(P<0.01).No significant difference was seen in VAS,operation time and blood loss between two groups(P<0.05). Conclusions:PKP and PVP have the similar therapeutic efficacy in treatment of VCF with minimal invasion,less operation time and blood loss.However, PKP is superior in the recovery of vertebral height.
