Abstract:
Objective To compare the clinical outcomes between conventional percutaneous vertebroplasty (PVP) and targeted PVP in the treatment of osteoporotic vertebral compression fractures (OVCFs).Methods A retrospective cohort study was designed to review 215 cases of single level OVCFs hospitalized between January 2014 and December 2015.According to the procedure techniques,the patients were assigned to targeted PVP group (89 cases) and conventional PVP group (126 cases) which was further divided into sufficient filled subgroup (110 cases) and insufficient filled subgroup (16 cases) on basis of cement distribution.Key techniques of targeted PVP included accurate needle insertion to fractured area and cement injection using a push rob with a side opening.Operating time,cement injection volume,rate and types of cement leakage,cement distribution in the fractured area and visual analogue score (VAS) of back pain were compared between the two groups.Results Operating time in targeted PVP group was longer than that in conventional PVP group (P ＜ 0.05).There were no significant differences in cement injection volume and rate and types of cement leakage between the two groups (P ＞ 0.05).None in targeted PVP group showed insufficient cement distribution in fractured area,while 16 cases (12.7％) in conventional PVP group (P ＜ 0.05).No significant differences in preoperative VAS of back pain existed among targeted PVP group,sufficient subgroup and insufficient subgroup (P ＞ 0.05).VAS of back pain was significantly decreased after PVP in three groups (P ＜ 0.05).Difference in postoperative VAS of back pain between targeted PVP group and sufficient filled subgroup was insignificant (P ＞0.05).However,postoperative VAS of back pain in insufficient filled subgroup was significantly increased compared with targeted PVP group and sufficient filled subgroup (P ＜ 0.05).Conclusion Targeted PVP provides sufficient cement to fill the fractured area and decreases incidence of unsatisfactory clinical outcome compared with traditional PVP,indicating a secure and effective new technique in the treatment of OVCFs.
