To evaluate the clinical efficacy of percutaneous curved vertebroplasty (PCVP) in treating thoracic and lumbar osteoporotic vertebral compression fractures (OVCFs).
Patients with thoracolumbar OVCFs were recruited and randomly divided into three treatment groups: PCVP, unilateral percutaneous vertebroplasty (PVP) or bilateral PVP. Bone cement dispersion in the fractured vertebrae was observed. Surgery duration, X-ray frequency, bone cement injection volume, bone cement leakage rate and visual analogue scale (VAS) scores were recorded.
Among 78 patients included, surgery duration and X-ray frequency were significantly lower in the PCVP and unilateral PVP groups versus bilateral PVP group. Bone cement injection volume was significantly higher in the bilateral PVP group (6.3 ± 1.4 ml) versus unilateral PVP (3.5 ± 1.1 ml) and PCVP groups (4.6 ± 1.2 ml). VAS scores at 24 h and 3 months post-surgery were significantly decreased versus baseline in all groups. The bone cement leakage rate was lowest in the PCVP group (8.8% [3/34 patients]).
PCVP is associated with reduced trauma, less complicated surgery with shorter duration, fewer X-rays, lower complication rate, and quicker postoperative recovery versus unilateral and bilateral PVP.
评估经皮弯曲椎体成形术（PCVP）治疗胸腰椎骨质疏松性椎体压缩骨折（OVCFs）的临床疗效。
招募胸腰椎OVCFs患者并随机分为三个治疗组：PCVP组、单侧经皮椎体成形术（PVP）组或双侧PVP组。观察骨折椎体内骨水泥的弥散情况。记录手术时间、X线检查次数、骨水泥注入量、骨水泥渗漏率和视觉模拟评分（VAS）。
纳入的78例患者中，PCVP组和单侧PVP组的手术时间和X线检查次数显著低于双侧PVP组。双侧PVP组的骨水泥注入量（6.3±1.4 ml）显著高于单侧PVP组（3.5±1.1 ml）和PCVP组（4.6±1.2 ml）。所有组术后24小时和3个月时的VAS评分均较基线显著降低。PCVP组的骨水泥渗漏率最低（8.8%[3/34例患者]）。
与单侧和双侧PVP相比，PCVP具有创伤小、手术操作简单、手术时间短、X线检查次数少、并发症发生率低和术后恢复快的优点。
