Influence of Different Bone Cement Injection on Patients with Single Segment Thoracolumbar OVCF

Abstract：Objective To investigate the influence of bone cement injection schemes by unilateral, near middle-line and bilateral on postoperative pain degree and perioperative complications of patients with single segment thoracolumbar OVCF.Methods 165 patients with single segment thoracolumbar OVCF were chosen from July 2015 to March2017 and randomly divided into three group including A group (55 patients) with bone cement injection schemes by unilateral, B group (55 patients) with bone cement injection schemes by near middle-line and C group (55 patients) with bone cement injection schemes by bilateral;and the pain VAS score before and after operation, intraoperative and postoperative complication incidence of both groups were compared.Results The pain VAS score in 1 dafter operation of B group and C group were significantly lower than A group (P＜0.05).There was no significant difference in the pain VAS score in 12 weeks, 24 weeks and 48 weeks after operation between 2 groups (P＞0.05).The bone cement leakage incidence of C group were significantly lower than A group and B group (P＜0.05).The re-cement injection rate of A group were significantly higher than B group and C group (P＜0.05).Conclusion Compared with bone cement injection schemes by unilateral, bone cement injection schemes by near middle-line and bilateral in the treatment of patients with single segment thoracolumbar OVCF can efficiently relieve early postoperative pain and reduce perioperative risk of complications.
