摘要:


文题释义:

高龄骨质疏松性椎体压缩骨折:指≥80岁的骨质疏松患者罹患椎体压缩骨折,未诊率及漏诊率高,骨质疏松严重,通常T≤-2.5 SD或骨密度< 80 mg/cm3,椎体压缩程度一般为1/3-3/5,上终板、部分下终板及椎体后壁破裂占比较多,椎体骨不连或假关节形成占比较多,同时合并众多基础疾病。
骨水泥间隔灌注联合体位复位技术:术前垫枕将胸部和髂部垫高,使患者呈过伸位,手法复位骨折,尽可能纠正伤椎后凸畸形或使其呈前凸位;术中分次调制骨水泥间隔注入复位椎体。

背景:椎体成形用于治疗骨质疏松性椎体压缩骨折已经历了20余年的临床实践检验,但术中骨水泥渗漏迄今仍是临床所面临的棘手问题。
目的:评估骨水泥间隔灌注联合体位复位技术治疗高龄骨质疏松性椎体压缩骨折的临床疗效。
方法:收集南京医科大学附属苏州医院2015年5月至2020年12月共120例行经皮椎体后凸成形术治疗的骨质疏松性椎体压缩骨折患者,共120例,年龄≥80岁,根据骨水泥灌注技术分为常规注入组(n=60,骨水泥调制一次性注入)和间隔灌注联合体位复位组(n=60,术前体位复位+骨水泥分次调制注入)。比较两组患者术后1周及末次随访时的目测类比评分、Oswestry功能障碍指数、伤椎Cobb角、伤椎前缘高度、肺功能改善及骨水泥渗漏率。研究获得南京医科大学附属苏州医院批准(KL901173)。

结果与结论:①两组均获得术后12个月以上随访,间隔灌注联合体位复位组的骨水泥渗漏率低于常规注入组(3.3%,15.0%,P < 0.05);②两组患者术后的目测类比评分、Oswestry功能障碍指数均低于术前(P < 0.05),两组间比较差异无显著性意义(P > 0.05);③两组患者术后的伤椎Cobb角、伤椎前缘高度较术前明显改善,间隔灌注联合体位复位组术后1周及末次随访的伤椎Cobb角、伤椎前缘高度优于常规注入组(P < 0.05);④常规注入组患者术后的用力肺活量及最大通气量均较术前明显改善(P < 0.05),间隔灌注联合体位复位组术后的肺活量、用力肺活量及最大通气量均较术前明显改善(P < 0.05),并且间隔灌注联合体位复位组术后1周及末次随访的肺活量、用力肺活量及最大通气量均大于常规注入组(P < 0.05);⑤结果表明,采用骨水泥间隔灌注联合体位复位技术治疗高龄骨质疏松性椎体压缩骨折可以获得满意的临床及影像学效果,且能显著降低骨水泥渗漏并改善患者肺功能。

Abstract: BACKGROUND: Vertebroplasty in the treatment of osteoporotic vertebral compression fracture has experienced more than 20 years of clinical practice, but the intraoperative bone cement leakage is still a difficult clinical problem.
OBJECTIVE: To evaluate the efficacy of bone cement interval perfusion in hyperextension position for treatment of senile osteoporotic vertebral compression fractures.  
METHODS: Between May 2015 and December 2020, 120 patients who suffered from osteoporotic vertebral compression fractures were treated with percutaneous kyphoplasty in hyperextension position in the Affiliated Suzhou Hospital of Nanjing Medical University. The patients were at the age of ≥ 80 years. According to the way of bone cement perfusion, they were randomly divided into conventional bone cement injection group (n=60, bone cement mixed one-time injection) and bone cement interval perfusion combined reduction group (n=60, preoperative position reduction + bone cement perfusion at different times). Visual analogue scale score, Oswestry dability index, Cobb angle, anterior edge height of injured vertebra, improvement of lung function, and the occurrence of cement leakage were compared between the two groups 1 week postoperatively and during final follow-up. This study was approved by the Affiliated Suzhou Hospital of Nanjing Medical University (approval No. KL901173). 
RESULTS AND CONCLUSION: (1) Both groups were followed up for more than 12 months after surgery. The bone cement leakage rate in the bone cement interval perfusion combined reduction group was lower than that in the conventional bone cement injection group (3.3%, 15.0%, P < 0.05). (2) The visual analogue scale score and Oswestry dability index of the two groups after surgery were lower than those before operation (P < 0.05), and there was no significant difference between the two groups (P > 0.05). (3) The postoperative Cobb angle of the injured vertebrae and anterior edge height of injured vertebra were significantly improved compared with that before operation. The Cobb angle and anterior edge height of injured vertebra in the bone cement interval perfusion combined reduction group were better than those in the conventional bone cement injection group at 1 week after operation and the last follow-up (P < 0.05). (4) The forced vital capacity and maximum voluntary ventilation of patients in the conventional bone cement injection group were significantly improved after surgery compared with those after surgery (P < 0.05). The postoperative vital capacity, forced vital capacity and maximum voluntary ventilation in the bone cement interval perfusion combined reduction group were significantly improved compared with preoperative data (P < 0.05). Vital capacity, forced vital capacity, and maximum voluntary ventilation in the bone cement interval perfusion combined reduction group 1 week after operation and the last follow-up were higher than those of the conventional bone cement injection group (P < 0.05). (5) The results showed that satisfactory imaging and clinical results can be obtained by the method of bone cement interval perfusion in hyperextension position. This method can significantly reduce the incidence of bone cement leakage and improve lung function.
