经皮椎体后凸成形术治疗骨质疏松性胸腰椎爆裂骨折

Percutaneous kyphoplasty in the treatment of osteoporotic thoracolumbar vertebral burst fractures

目的探讨经皮椎体后凸成形术(PKP)治疗骨质疏松性胸腰椎爆裂骨折的临床疗效。方法采用PKP治疗42例骨质疏松性胸腰椎爆裂骨折患者。记录疼痛VAS评分,测量伤椎前缘高度百分比及后凸Cobb角。结果患者均获得随访,时间12~13个月。未出现骨水泥向椎管内渗漏及神经、血管损伤。疼痛VAS评分、伤椎前缘高度百分比、伤椎后凸Cobb角术后即刻及术后12个月与术前比较差异均有统计学意义(P<0.05);疼痛VAS评分术后12个月与术后即刻比较差异有统计学意义(P<0.05);伤椎前缘高度百分比及后凸Cobb角术后12个月与术后即刻比较差异均无统计学意义(P>0.05)。结论采用PKP治疗骨质疏松性胸腰椎爆裂骨折可明显缓解疼痛,恢复骨折椎体的高度,是一种有效的方法。

Objective To explore the clinical effect of percutaneous kyphoplasty(PKP)in the treatment of osteoporotic thoracolumbar burst fractures.Methods The 42 patients underwent PKP for osteoporotic thoracolumbar burst fractures.The pain visual analogue scale(VAS)were recorded,the anterior edge height percentage and the kyphotic Cobb angle of the injured vertebrae were measured.Results All patients were followed up for 12~13 months.There were no leakage of cement into the spinal canal,nerve and blood vessel injuries.There were statistically significant differences in the pain VAS,the percentage of anterior edge height and kyphotic Cobb angle of the injured vertebrae immediately after surgery and 12 months after surgery,compared with those before surgery(P<0.05).Compared with immediately after operation,there was statistically significant difference in pain VAS at 12 months after operation(P<0.05);and there were no significant differences in the percentage of anterior edge height and kyphotic Cobb angle of the injured vertebrae at 12 months postoperation(P>0.05).Conclusions For osteoporotic thoracolumbar burst fractures,PKP is an effective method to relieve the pain and restore the height of the fractured vertebrae.
