To compare outcomes of unipedicular versus bipedicular approach for percutaneous vertebroplasty for the treatment of thoracolumbar acute osteoporotic vertebral compression fracture (AOVCF).
From November 2014 to September 2015, 382 patients with AOVCF were randomly assigned to the unipedicular and bipedicular groups. Clinical outcomes and complications were compared.
Both groups were comparable with respect to bone cement leakage and adjacent vertebral fractures (P> 0.05). Although the bipedicular approach was found to be superior in terms of reduction of kyphosis and loss of reduction, frequency of x-ray fluoroscopy, VAS and ODI scores, the volume of cement injected and operating time, the between-group differences were not statistically significant (P> 0.05). Nerve root stimulation was more frequent in the unipedicular group (P< 0.05).
The clinical and radiological outcomes of both procedures were comparable. The unipedicular approach was associated with more nerve root stimulation.
比较单椎弓根与双椎弓根入路经皮椎体成形术治疗胸腰椎急性骨质疏松性椎体压缩骨折（AOVCF）的疗效。
2014年11月至2015年9月，将382例AOVCF患者随机分为单椎弓根组和双椎弓根组。比较两组的临床疗效和并发症。
两组在骨水泥渗漏和相邻椎体骨折方面具有可比性（P>0.05）。虽然双椎弓根入路在矫正后凸畸形和防止矫正度丢失、X线透视次数、视觉模拟评分（VAS）和Oswestry功能障碍指数（ODI）评分、骨水泥注入量及手术时间方面更具优势，但组间差异无统计学意义（P>0.05）。单椎弓根组神经根刺激更为频繁（P<0.05）。
两种手术方法的临床和影像学疗效相当。单椎弓根入路与更多的神经根刺激相关。
