UNASSIGNED: A total of 132 patients treated with PVP for osteoporotic vertebral compression fractures (OVCF) were included and divided into injured group (52 cases) and non-injured group (80 cases) according to the existence of thoracolumbar fascia injury. Before surgery, 1 day, 3 days, 1 week, 1 month, and 3 months after surgery, and at the last follow-up, the primary patient-reported outcome measures (PROMs) were the visual analogue scale (VAS) of pain while rolling over and standing, and the secondary PROMs was the Oswestry disability index (ODI). Meanwhile, the achieved rate of minimal clinically important differences (MCID) and patient acceptable symptom states (PASS) of the above measures in both groups was evaluated at the last follow-up.
UNASSIGNED: Except for the postoperative 3 months and the last follow-up, there were statistically significant differences in VAS-standing and ODI between the two groups at other time points after surgery (P < 0.05), and the non-injured group was significantly better than the injured group. At the last follow-up, there was no statistically significant difference in the MCID and PASS achievement rates of the above measures between the two groups (P > 0.05). In addition, the proportion of patients who got out of bed 1 and 3 days after surgery in the non-injury group was significantly higher than that in the injury group (P = 0.000 for both).
UNASSIGNED: Thoracolumbar fascia injury significantly affected early pain relief and extended time of getting out of bed after PVP. Attention should be paid to preoperative evaluation of thoracolumbar fascial injury in order to better predict the postoperative efficacy of PVP.
■共132例采用PVP治疗骨质疏松性椎体压缩骨折(OVCF)患者,根据是否存在胸腰椎筋膜损伤分为损伤组(52例)和非损伤组(80例)。手术前,1天,3天,1周,1个月,手术后3个月,在最后一次随访中,患者报告的主要结局指标(PROMs)是翻身和站立时疼痛的视觉模拟评分(VAS),次要PROM是Oswestry残疾指数(ODI)。同时,在最后一次随访时评估了上述指标在两组中达到的最小临床重要差异率(MCID)和患者可接受症状状态(PASS).
■除了术后3个月和最后一次随访,术后其他时间点两组VAS-standing和ODI比较差异有统计学意义(P<0.05),非损伤组明显优于损伤组。在最后一次随访中,两组上述指标的MCID和PASS达标率比较,差异无统计学意义(P>0.05)。此外,非损伤组术后1天和3天下床的患者比例明显高于损伤组(P=0.000)。
■胸腰椎筋膜损伤显著影响PVP术后早期疼痛缓解和下床时间延长。应重视胸腰椎筋膜损伤的术前评估,以更好地预测PVP术后疗效。
