摘要
目的:探究骨质疏松性椎体压缩骨折(Osteoporotic Vertebral Compression Fractures,OVCFs)患者椎经皮椎体成形术(Percutaneous Vertebroplasty,PVP)术后体分区CT值的检测意义。方法:回顾性分析2022年2月至2024年11月在我院行PVP治疗的66例OVCFs患者临床及随访资料,根据随访期间(随访6 m内)手术相关不良事件发生情况分两组,术后3 d两组患者均采用CT检查,并对比两组骨密度、体分区CT值,采用日本骨科协会评估治疗分数(Japanese Orthopaedic Association,JOA)评估两组患者腰椎功能并对比,采用Pearson相关系数分析L1椎体平均CT值与患者骨密度及腰椎功能的相关性。结果:66例OVCFs患者的95个骨折椎体经PVP治疗,发生12例(17椎)骨水泥渗漏,5例(9椎)邻椎新发骨折,2例静脉栓塞,共计19例,发生率为28.79%;预后良好组患者的骨密度、JOA评分、L1椎体水平分区平均CT值(上、中、下部分)均高于预后不良组(P<0.05);OVCFs患者术后3 d的L1椎体平均CT值(上、中、下部分)与患者骨密度、腰椎功能JOA评分均呈正相关(P<0.05)。结论:行PVP治疗预后不良的OVCFs患者存在骨密度、术后L1椎体水平分区平均CT值及腰椎功能评分偏低的现象,且体分区CT值与患者骨密度、腰椎功能密切相关。
Objective:To explore the detection significance of vertebral body partition CT value in patients with osteoporotic vertebral compression fractures(OVCFs)after percutaneous vertebroplasty(PVP).Methods:The clinical data and followup data of 66 patients with OVCFs who received PVP in the hospital from February 2022 to November 2024 were retrospectively analyzed.According to the occurrence of surgery-related adverse events during follow-up(within 6 months of follow-up),the patients were divided into two groups.All patients received CT examination at 3 days after surgery.The bone mineral density and vertebral body partition CT value were compared between the two groups.Lumbar function of the two groups was evaluated by Japanese Orthopedic Association(JOA)score and compared.Pearson correlation coefficient was adopted to analyze the correlation between average CT value of L1 vertebral body partition and bone mineral density and lumbar function of patients.Results:Among the 95 fractured vertebral bodies of 66 patients with OVCFs treated by PVP,12 cases(17 vertebrae)had bone cement leakage,5 cases(9 vertebrae)had new adjacent vertebral fractures,and 2 cases had venous embolism,with 19 cases in total and the incidence rate of 28.79%.The bone mineral density,JOA score and average CT values(upper,middle and lower parts)of L1 vertebral body partition in good prognosis group were higher than those in poor prognosis group(P<0.05).The average CT values of L1 vertebral body(upper,middle and lower parts)in OVCFs patients at 3 days after surgery were positively correlated with bone mineral density and lumbar function JOA score(P<0.05).Conclusion:OVCFs patients with poor prognosis after PVP have lower bone mineral density,lower average CT value of L1 vertebral body partition and lower lumbar function score after surgery,and vertebral body partition CT value is closely related to the bone mineral density and lumbar function of patients.
