骨质疏松性椎体压缩骨折是骨质疏松症的严重并发症。各种椎体后凸成形术是治疗退行性椎体压缩骨折的常用方法，各有其独特之处。根据胸腰椎椎弓根横径是纵径的2倍这一解剖特点，设计了Jack椎体扩张器，通过对机械力的控制，使椎体高度得到更好的恢复。218例患者均获随访，随访时间3 ~ 30个月，平均14.2个月。结果12例患者出现骨水泥渗漏，无明显症状。未发现其他并发症。术前、术后1周和末次随访时，VAS评分分别为8.2 ± 1.3、1.7 ± 0.9和1.8 ± 0.8，ODI分别为78.2 ± 13.3%、18.5 ± 7.3%和20.9 ± 6.8%。术前、术后1周和末次随访时，前部椎体高度分别为19.3 ± 3.2、25.1 ± 2.6和24.9 ± 2.6 mm，中部椎体高度分别为18.7 ± 3.0、24.8 ± 3.0和24.5 ± 2.9 mm。术前Cobb角为16.2° ± 6.6 °，术后1周Cobb角为8.1° ± 5.6 °，末次随访Cobb角为8.5° ± 5.6°。
BackgroundOsteoporotic vertebral compression fracture is a serious complication of osteoporosis. Various vertebral kyphoplasty surgeries, which have their own unique features, are commonly used for osteoporotic vertebral compression fracture. Based on the anatomic property of the thoracolumbar vertebral pedicle that its horizontal diameter is twice that of the vertical diameter, we designed Jack vertebral dilator for better restoration of the vertebral height by manipulating the mechanical force.MethodsA total of 218 patients (236 vertebrae) with osteoporotic vertebral compression fracture were treated with Jack vertebral dilator. Surgery was successfully completed in all cases, and all the 218 patients were followed up for an average of 14.2 months (range 3 to 30 months).ResultsBone cement leakage occurred in 12 cases, but no symptoms were reported. No other complications were noticed. The VAS scores were 8.2 ± 1.3, 1.7 ± 0.9, and 1.8 ± 0.8 and the ODI was 78.2 ± 13.3 %, 18.5 ± 7.3 %, and 20.9 ± 6.8 % before surgery and 1 week after surgery and at the final follow-up, respectively. The anterior vertebral body height was 19.3 ± 3.2, 25.1 ± 2.6, and 24.9 ± 2.6 mm and the central vertebral body height was 18.7 ± 3.0, 24.8 ± 3.0, and 24.5 ± 2.9 mm before surgery and 1 week after surgery and at the final follow-up, respectively. Cobb angle was 16.2° ± 6.6°, 8.1° ± 5.6°, and 8.5° ± 5.6° before surgery and 1 week after surgery and at the final follow-up, respectively.ConclusionsJack vertebral dilator kyphoplasty for osteoporotic vertebral compression fracture is safe, feasible, and effective and has the prospect of further broad application in the future.
