骨水泥在椎体骨折线内弥散情况对椎体成形术治疗效果的影响

目的对椎体骨折线内弥故情况进行研究，分析骨水泥在椎体骨折线内弥散情况对椎体成形术治疗效果的影响。方法：选取骨质疏松性椎体压缩性骨折患者40例，按椎体骨折线内骨水泥弥散情况将其分为实验组和对照组各20例，比较两组患者基线特征，术前、术后3d、末次随访的ODI及局部Cobb角变化。结果：对照组有3例进展性后凸畸形；两组体重、疼痛评分，术前与末次随访ODI无显著差异：实验组骨密度、术前Cobb角、术后3dODI、术后3dCobb角、末次随访ODI及Cobb角均小于对照组，差异显著（P〈0．05）。结论：骨水泥在椎体骨折线内弥散情况不会对椎体成形术治疗效果产生影响，但骨质疏松性椎体压缩性骨折患者术后具有发生进展性后凸畸形的可能性。

Objective To study of vertebral fracture line dispersion conditions, analysis of bone cement in vertebral fracture line dispersion effect for the treatment of vertebral plasty. Selection methods： from February 2015 to May 2015 our hospital during the period of 40 patients with osteoporotic vertebral compression fractures as the research object, according to the vertebral body fracture line in bone cement dispersion condition will be divided into the experimental group and the control group （n = 20, compared two groups of patients with baseline characteristics, preoperative and postoperative 3 d, the ODI and local Cobb Angle changes of the last follow-up. Results： the control group after three cases progress protrusion deformity; At the end of the two groups of body weight, pain score, preoperative and follow-up ODI no significant difference; Experimental bone mineral density, preoperative Cobb Angle, 3 d ODI after operation, postoperative 3 dcobb Angle, the last follow-up ODI and Cobb Angle is less than the control group, significant difference, with statistical significance. Conclusion： the bone cement in vertebral fracture line dispersion effects for the treatment of vertebral plasty hasn＇t, but postoperatively in patients with osteoporotic vertebral compression fractures with the possibility of progress protrusion deformity after sex.
