目的 探究在胸腰段椎体成形术椎再骨折患者中采用后路椎体次全切治疗的临床疗效,并对其进行探讨与分析。方法 随机选取2019年1月—2021年1月于我院骨科治疗的胸腰段椎体成形术椎再骨折患者58例作为研究对象。给予患者后路椎体次全切治疗,记录患者的手术时间及术中出血量,对比手术前以及手术后6个月患者的VAS疼痛评分、后凸Cobb角、椎体高度、椎管容积率以及美国脊柱损伤协会(ASIA)损伤分级。结果 患者的手术时间为1.4～3.8 h,手术平均时间为(2.45±0.61)h,患者术中出血量为580～1 470 mL,术中平均出血量为(835.48±134.75)mL。手术后6个月患者的VAS疼痛评分低于手术前(P＜0.05);手术后6个月患者的后凸Cobb角小于手术前(P＜0.05);手术后6个月患者的椎体高度和椎管容积率均大于手术前(P＜0.05);患者手术前ASIA损伤分级: A级12例、B级14例、C级16例、D级12例、E级4例;患者手术后6个月ASIA损伤分级:A级5例、B级8例、C级13例、D级15例、E级17例。结论 在胸腰段椎体成形术椎再骨折患者中采用后路椎体次全切治疗可缓解患者的疼痛感,减小后凸Cobb角,增大椎体高度和椎管容积率以及改善患者的ASIA损伤分级。

Objective To investigate the clinical efficacy of posterior subtotal vertebral dissection in patients with vertebral re-fractures of thoracolumbar segmental vertebroplasty. Methods Fifty-eight patients with thoracolumbar segmental vertebroplasty vertebral re-fractures treated in the orthopedic department of our hospital from January 2019 to January 2021 were randomly selected as study subjects.The patients were treated with posterior subtotal vertebral dissection, and the operating time and intraoperative bleeding of the patients were recorded, and the VAS pain score, posterior convex Cobb angle, vertebral body height, spinal canal volume ratio, and American Spinal Injury Association (ASIA) injury classification were compared in patients before and 6 months after surgery. Results The operating time was 1.4-3.8 hours, with a mean of (2.45±0.61) hours, and the intraoperative bleeding was 580-1470 mL, with a mean of (835.48±134.75) mL.The VAS pain scores at 6 months after surgery were lower than those before surgery (P<0.05); the posterior convex Cobb angle at 6 months after surgery was smaller than that before surgery (P<0.05); the vertebral body height and spinal canal volume ratio at 6 months after surgery were greater than those before surgery (P<0.05). Preoperative ASIA injury grading: 12 cases with grade A, 14 cases with grade B, 16 cases with grade C, 12 cases with grade D and 4 cases with grade E; six months after surgery, 5 cases with grade A, 8 cases with grade B, 13 cases with grade C, 15 cases with grade D, and 17 cases with grade E. Conclusion Posterior subtotal vertebral body resection could relieve pain of thoracolumbar vertebroplasty fractures, reduce the posterior convex Cobb angle, increase vertebral body height and spinal canal volume, and improve ASIA injury classification.

目的 回顾分析椎体成形术(PVP)对于治疗骨质疏松性新鲜椎体压缩骨折(OVCF)患者的疗效。方法 收集2011年1月—2012年6月新鲜OVCF患者伤后两周内行PVP术治疗共34例(51个椎体)。于术前1天、术后3天、1个月、3个月、6个月、12个月予VAS、ODI评分,并行X线检查以测量病椎前、中、后缘的高度和病椎cobb角。结果 纳入研究的34个病例中,患者术后各时间点随访中VAS和ODI评分均较术前1天明显改善(P<0.05)。术后各时间点随访中行X线检查时,术后各次随访中椎体前缘、中段、病椎cobb角均较术前有较为明显的矫正(P<0.05)。结论 应用PVP治疗新鲜OVCF疗效满意,可快速缓解疼痛、改善生活质量和矫正病椎后凸畸形。

Objective To study the efficiency and safety of percutaneous Vertebroplasty(PVP) for the fresh osteoporotic vertebral compression fractures(OVCF). Methods 34 patients (30 females and 4 males), mean age 75.8 years old(75.79±9.32, range 60 to 93 years old) hospitalized between January 2011 to June 2012 were reviewed retrospectively in this study. Evaluation at follow-up time point(1 day before PVP, 3rd day, 1st, 3rd, 6th, 12th month after PVP) included the pain score with VAS, mobility improvement with ODI and the measurement of anterior, middle and posterior height of the fractured vertebra, and kyphotic angle of the fractured vertebra with X-ray image. Results For the 34 patients by followed up 1 year, the mean VAS score and ODI decreased significantly after PVP at any follow-up time compared with the 1 day before operation. Anterior and middle body height and the focal kyphotic angle at any follow-up time after PVP was improved statistically significant compared with the preoperative value(P<0.05). Conclusion Percutaneous vertebroplasty results in prompt pain relief, rapid rehabilitation and kyposis reduction, it is a safe and effective procedure for treating fresh osteoporotic vertebral compression fractures.
