文题释义:
骨质疏松:是一种以骨组织量减少为特点的代谢性骨病变,WHO根据骨密度指标,规定正常人骨密度值加减1个标准差(SD)为正常值,降低1-2.5个SD为骨质减少,降低2.5个SD以上为骨质疏松症。骨质疏松性椎体骨折是骨质疏松症的严重后果,部分患者由轻微损伤即可造成脆性骨折,多属于完全骨折。
椎体后凸成形:临床全称为经皮穿刺椎体后凸成形术,属于微创手术,是通过向病变椎体内注入骨水泥(聚丙烯酸甲酯)达到强化椎体的技术。1984 年由Deramond发明并首次应用,1994年美国首次报道将椎体成形应用于骨质疏松性椎体骨折的治疗,Belkoff等认为2 mL骨水泥即可恢复椎体强度,而腰椎注射6 mL、胸腰段注射8 mL可恢复椎体刚度。
 
 
背景:椎体后凸成形骨水泥注射治疗骨质疏松性椎体压缩骨折具有较好的临床疗效,但其对脊柱不同部位的疗效是否存在差异?
目的:比较椎体后凸成形骨水泥注射治疗不同部位骨质疏松性椎体压缩骨折的疗效。
方法:回顾性分析2011年1月至2014年8月在苏州大学附属第一医院骨科接受治疗的247例单节段骨质疏松性椎体压缩骨折患者的临床资料,其中上中胸段(T1-T10)骨折患者24例,胸腰段(T11-L2)骨折患者187例,下腰段(L3-L5)骨折患者36例,3组均进行椎体后凸成形骨水泥注射治疗。比较3组手术时间、术中透视次数、骨水泥注射量及渗漏情况,以及手术前后的目测类比评分、椎体高度恢复及畸形矫正情况。

结果与结论:①所有患者均顺利完成手术,随访12-44个月,平均(25.44±7.85)个月;②共18例患者发生骨水泥渗漏,其中上中胸段组3例(12.5%),胸腰段组13例(6.4%),下腰段组2例(5.6%);③上中胸段组手术时间、透视次数多于胸腰段组、下腰段组(P < 0.05),骨水泥注射量少于胸腰段组、下腰段组(P < 0.05);胸腰段组与下腰段组手术时间、透视次数、骨水泥注射量比较无差异(P > 0.05);④术前、术后1 d及末次随访时,3组间目测类比评分、Oswestry功能障碍指数、伤椎前缘高度比值、Cobb角比较差异均无显著性意义    (P > 0.05);3组术后1 d、末次随访时的目测类比评分、Oswestry功能障碍指数、伤椎前缘高度比值均较术前明显改善(P < 0.05);⑤结果表明,椎体后凸成形骨水泥注射治疗不同部位骨质疏松性椎体压缩骨折均可获得满意的疗效。

Abstract:

BACKGROUND: Kyphoplasty with bone cement injection for the treatment of osteoporotic vertebral compression fractures has a good clinical effect, but it is unclear whether there is a difference in the efficacy on the fractures in different parts of the spine.

OBJECTIVE: To compare the outcomes of kyphoplasty with bone cement injection in the treatment of osteoporotic vertebral compression fractures in different parts of the spine.
METHODS: We retrospectively analyzed the clinical data of 247 cases of single-segmental osteoporotic vertebral compression fractures undergoing kyphoplasty with bone cement injection at the Department of Orthopaedic Surgery, the First Affiliated Hospital of Soochow University in China from January 2011 to August 2014. There were 24 cases of upper and middle thoracic (T1-T10) fractures, 187 cases of thoracolumbar (T11-L2) fractures and 36 cases of lower lumbar (L3-L5) fractures. The surgical time, X-ray exposure time, bone cement volume and leakage, the Visual Analog Scale score, the Oswestry Disability Index score, anterior vertebral height ratio and Cobb angle were assessed preoperatively, at 1 day posteroperatively and at the final visit.
RESULTS AND CONCLUSION: (1) All patients underwent the surgery successfully, and were followed up for 12-44 months, with an average of (25.44±7.85) months. (2) There were 18 cases of bone cement leakage in the three groups, including 3 (12.5%) cases of upper and middle thoracic fractures, 13 (6.4%) cases of thoracolumbar fractures and 2 (5.6%) cases of lower lumbar fractures. (3) The surgical time and X-ray exposure time were significantly higher in the patients with upper and middle thoracic fractures than those with thoracolumbar fractures or lower lumbar fractures (P < 0.05), while the volume of bone cement was significantly lower than that in the other two groups (P < 0.05). Additionally, there were no significant differences in the surgical time, X-ray exposure time, and amount of bone cement between the patients with thoracolumbar fractures and with lower lumbar fractures (P > 0.05). (4) There were no significant differences in the Visual Analog Scale score, Oswestry Disability Index score, anterior vertebral height ratio and Cobb angle among the three groups preoperatively, at 1 day postoperatively and at the final visit (all P > 0.05). However, compared with baseline, these indicators were significantly improved in each group at 1 day postoperatively and at the final visit (P < 0.05). (5) To conclude, kyphoplasty with bone cement injection has achieved satisfactory outcomes in the treatment of osteoporotic vertebral compression fractures in different parts of the spine.
