Comparative analysis on curative effects of percutaneous vertebroplesty and kyphoplasty in the treat-ment for thoracolumbar vertebral compression fracture

Abstract

[Objective]To explore and compare the clinical efficacy of treatment of thoracolumbar vertebral compression fracture by percutaneous vertebroplasty(PVP) and percutaneous kyphoplasty(PKP).[Methods]46 cases of thoracolumbar vertebral compression fractures in patients with surgical Methods were divided into vertebral angioplasty group and kyphoplasty group,intraoperative blood loss of two groups,operative time,the bone cement injected volume,bone cement leakagerate and clinical efficacy before and after surgery were compared in two groups.Resrlts Patients were successfully completed with surgery,infection,complications of hematoma,nerve root injury,and vertebral body fractures.There was no statistical significant difference in operative time and blood loss in two groups(P＞ 0.05).But there was significant differences in the injection volume of hone cement,bone cement leakage rate between the two groups (P＜0.05).Two groups' restoring vertebral height extent had significant improvement in VAS score than the preoperative group,difference was statistically significant (P＜ 0.05) but no significant difference found between two groups (P＞ 0.05).Mter 2weeks in PVP group,and the PKP group,1 year after the efficiency difference was not significant (P＞ 0.05).[Conclusion]s PVP and PKP treatment of thoracic and lumbar vertebral compression fracture may derive significant clinical efficacy,with less trauma,shorter operative time,less bleeding,fewer complications,minimally invasive characteristics.PKP can effectively correct the kyphosis,greatly reduce the occurrence of bone cement leakage than PVP increased security,hut the cost is higher; PVP operation is relatively simple,inexpensive,hut the bone cement leakage rate is relatively high.It should be combined with a vasiety of factors to select the appropriate surgical clinical.
