摘要
目的评价新型微创经皮椎弓根螺钉(Sextant—R)内固定治疗胸腰椎骨折的效果。方法选择36例胸腰椎骨折患者分为Sextant—R组(14例)和开放手术组(22例),对比分析手术切口、手术时间、出血量以及后凸畸形矫正率等。结果Sextant—R组手术切口长度(7.1±0.9)cm,手术时间(1.1±0.7)h,出血量(89.3±12.1)ml,术后引流量(12.6±3.2)ml,术后平均Cobb角(4.5±2.4)°,术后椎体矢状面指数(10.2±10.1)°,术后伤椎椎体前缘高度(85.0±7.0)%。开放手术组手术切口长度(16.8±1.6)cm,手术时间(2.4±0.8)h,出血量(325.0±123.6)ml,术后引流量(147.3±36.1)ml,术后Cobb角(1.0±2.3)°,术后椎体矢状面指数(5.5±8.6)°,术后伤椎椎体前缘高度(95.5±2.2)%。结论在严格掌握手术适应证的前提下,Sextant—R内固定是治疗胸腰椎骨折的较好选择。
Objective To assess the minimally invasive surgical therapeutic result of percutaneous pedicle screw fixation using Sextant-R system in treating thoracolumbar fractures. Methods A total of 36 patients with thoracolumbar fractures were divided into two groups, ie, Sextant-R percutaneous pedicle screw fixation group (Sextant-R group, 14 patients) and open pedicle screw fixation group (open surgery group, 22 patients). A comparative study was done on surgical incision, operation duration, surgical blood loss and deformity correction. Results In Sextant-R group and open surgery group respectively, the incision size was (7. 1 ±0.9) cm and (16.8±1.6) cm (P〈0.05), operation duration ( 1.1 ± 0.7 ) hours and ( 2.4 ± 0.8 ) hours ( P 〈 0.05 ) , surgical blood loss ( 89.3 ±12.1 ) ml and ( 325.0 ± 123.6) ml ( P 〈 0.01 ), surgical draining loss ( 12.6 ± 3.2) ml and ( 147.3 ± 36.1 ) ml ( P 〈 0.01 ), postoperative improvement of Cobb' s angle (4.5 ± 2.4) ° and ( 1.0 ± 2.3 )° ( P 〈 0.05 ), sagittal index ( 10.2 ± 10.1 ) ° and (5.5 ± 8.6)° ( P 〈 0.05 ) and anterior height of fracture vertebral body ( 85.0 ± 7.0) % and (95.5 ± 2.2 ) % ( P 〈 0.05 ). Conclusion Percutaneous pedicle screw fixation using Sextant-R system is a good minimally invasive surgical choice for patients with thoracolumbar fracture under strict control of surgical indications.
