文题释义:
光电导航系统:该系统由导航工具、位置跟踪仪、监视器和工作站组成,将空间立体导航技术、计算机图像处理及可视化技术与临床手术结合起来,使手术器械的位置在术中通过影像实时显示。因精确性、安全性及快速性的特点使其在临床逐渐得到广泛应用。
经皮椎弓根螺钉技术:传统开放置钉技术为了暴露椎弓根钉置入点,广泛剥离、过度牵拉椎旁软组织有时难以避免。在此基础上,从20世纪80年代Magerl率先开展腰椎经皮穿刺固定术;该技术发展主要经历了3个阶段:外固定阶段、皮下内固定阶段以及现在广泛应用的深肌层内固定阶段,其较开放置钉有着独特的优点,目前已广泛应用于无神经症状的胸腰椎骨折治疗。
 
摘要
背景:光电导航引导下经皮椎弓根螺钉的植入已在临床中广泛开展,其准确性、安全性、有效性目前仍缺乏循证医学的证实。
目的:比较后路光电导航下经皮椎弓根螺钉复位固定术与传统开放手术治疗胸腰椎骨折的临床疗效。
方法: 61例胸腰椎骨折患者,分别采用光电导航下经皮椎弓根螺钉复位内固定治疗(31例,微创组)和传统开放后路椎弓根螺钉复位内固定(30例,开放组)治疗。对两组患者围手术期相关指标、影像学指标、术后功能恢复情况及并发症发生率并进行比较。
结果与结论:①微创手术组内固定后1周伤口疼痛评分、术中出血量、X射线透视次数、术后住院时间均显著低于或少于开放组(P < 0.05);②手术时间两组差异无显著性意义(P > 0.05);③两组内固定后椎体复位的影像学指标均较内固定前明显改善(P < 0.05);两组内固定后影像学指标较内固定改善程度差异无显著性意义(P > 0.05);④术后螺钉与上终板夹角微创组显著小于开放组(P < 0.05);⑤内固定后微创组优良植钉率显著高于开放组(P < 0.05);⑥结果说明,光电导航下经皮椎弓根螺钉内固定术治疗胸腰椎骨折与传统开放手术相比具有置钉准确性高、术中透视次数少、切口小、出血少、恢复快等优点。

Abstract:

BACKGROUND: Photoelectric navigation-aided percutaneous pedicle screw placement has been developed extensively, but its accuracy, safety and effectiveness have not yet been confirmed by evidence-based medicine.

OBJECTIVE: To compare the curative efficacy of photoelectric navigation-aided percutaneous pedicle screw placement and traditional open posterior pedicle screw fixation for thoracolumbar fractures.
METHODS: Sixty patients with thoracolumbar fractures were equivalently randomized to treatment and control groups and then underwent photoelectric navigation-aided percutaneous pedicle screw placement and traditional open posterior pedicle screw fixation, respectively. The perioperative indexes, imaging indexes, function recovery and incidence of complications were compared between two groups.
RESULTS AND CONCLUSION: (1) The Visual Analogue Scale scores, intraoperative blood loss, radiant times, and hospitalization time in the treatment group were significantly less than those in the control group (P < 0.05). (2) The operation time did not differ significantly between two groups (P > 0.05). (3) The postoperative sagittal Cobb angle, and percentage of anterior height in the vertebral body in the two groups were significantly improved compared with those before surgery (P < 0.05), but all above imaging indexes showed no significant differences between two groups (P > 0.05). The endplate-screw angle in the treatment group was significantly less than that in the control group (P < 0.05). (5) The excellent and good rate of placement in the treatment group was significantly higher than that in the control group  (P < 0.05). (6) These results suggest that compared with the traditional open posterior pedicle screw fixation, the photoelectric navigation-aided percutaneous pedicle screw placement exhibits high placement accuracy, less radiant times, less trauma, less blood loss and rapid functional recovery.
