To investigate prospectively the effectiveness of kyphoplasty with SKY bone expander system in treatment of compression fracture of thoracic/lumbar vertebrae and correction of the deformity.
Twenty-five patients with thoracic/ lumbar vertebral osteoporotic compression fracture were admitted to our hospital between March 2007 and March 2008, and treated by kyphoplasty with SKY bone expander system. Patient's pain status was rated with Visual Analogue Scale (VAS) score system 1 day before and 1 hour, 48 hours, 6 months, 12 months after surgery. In addition, Rolland-Morris and Oswestry disability questionnaires (RDQ and ODI) were used for survey 1 day before and 1, 6, 12 months after surgery. Pre- and post-operative vertebral heights and Cobb's angles were measured based on the X-ray films and statistically analyzed.
There were 27 fractured vertebrae in these 25 patients. After SKY kyphoplasty, the Cobb's angles (9.8 degree ± 9.76 degree) were significantly reduced compared with preoperative angles (17.18 degree ± 9.35 degree P < 0.05), and the average improvement rate was 39%. Patients'pain VAS scores were also greatly improved after operation (P < 0.05). Moreover, postoperative RDQ and ODI scores were significantly smaller than preoperative values (P < 0.05).
Kyphoplasty with SKY bone expander system provides an effective method for treating thoracic/ lumbar vertebral osteoporotic compression fracture, with the advantages of small surgical wound and short duration. It can effectively recover the anterior and medial heights of fractured vertebrae (33% and 50%, respectively), reduce the Cobb's angle, quickly alleviate pain and improve patients'quality of life in a relatively short time period.
前瞻性研究使用SKY骨扩张器系统进行椎体后凸成形术治疗胸腰椎压缩性骨折及矫正畸形的有效性。
2007年3月至2008年3月我院收治25例胸腰椎骨质疏松性压缩骨折患者，采用SKY骨扩张器系统进行椎体后凸成形术治疗。分别于术前1天及术后1小时、48小时、6个月、12个月采用视觉模拟评分法（VAS）评估患者疼痛状况。此外，于术前1天及术后1、6、12个月使用罗兰-莫里斯功能障碍问卷（RDQ）和奥斯维斯特功能障碍指数（ODI）进行调查。根据X线片测量术前及术后椎体高度和Cobb角，并进行统计学分析。
25例患者共27个骨折椎体。SKY椎体后凸成形术后，Cobb角（9.8°±9.76°）较术前角度（17.18°±9.35°）显著减小（P<0.05），平均改善率为39%。患者术后疼痛VAS评分也有显著改善（P<0.05）。此外，术后RDQ和ODI评分显著低于术前值（P<0.05）。
使用SKY骨扩张器系统进行椎体后凸成形术为治疗胸腰椎骨质疏松性压缩骨折提供了一种有效的方法，具有手术创伤小、时间短的优点。它能有效恢复骨折椎体的前缘和中线高度（分别为33%和50%），减小Cobb角，快速缓解疼痛，并在较短时间内改善患者生活质量。
