摘要:

背景:既往研究大多采用回顾性、小样本分析应用椎弓根置钉技术修复胸腰椎骨折的近期临床效果,结论较为单薄。同时有学者提出经伤椎置入螺钉可进一步稳定椎体,减少断钉断棒、矫正度丢失等情况。
目的:评价经伤椎椎弓根螺钉置入内固定修复胸腰椎骨折的远期效果。
方法:选取2010年2月至2012年2月广州市番禺区第二人民医院骨科收治的36例胸腰椎骨折患者,应用经伤椎椎弓根螺钉置入内固定治疗。治疗前伤椎前缘高度比平均36%,脊柱后凸角(Cobb角)25°,椎管正中矢状径60%,神经功能按Frankel分级:A级2例,B级6例,C级10例,D级9例,E级9例。比较患者治疗前和治疗后的伤椎前缘高度比、脊柱后凸角(Cobb角)、椎管正中矢状径以及神经功能Frankel分级情况。
结果与结论:治疗后随访3-3.5年,36例患者治疗后疼痛明显缓解,治疗后平均伤椎前缘高度比恢复到95%,脊柱后凸角(Cobb角)为3.5°,椎管正中矢状径恢复到96%,治疗前后患者的上述指标差异有显著性意义(P < 0.05)。治疗后神经功能恢复情况:A级1例,B级2例,C级3例,D级4例,E级26例。治疗后骨折均获得复位,未发生内固定断裂、松动,矫正丢失等并发症。提示经伤椎椎弓根螺钉置入内固定修复胸腰椎骨折能让骨折获得满意复位,增强脊柱的抗压稳定性,减少内固定断裂和椎体高度丢失,远期效果良好,说明植入物与宿主具有良好的生物相容性。

Abstract:

BACKGROUND: Many previous retrospective small-sample studies analyzed the short-term effects using pedicle screw placement to repair thoracolumbar fracture. Conclusions are relatively thin. Simultaneously, screw placement in the injured vertebra can further stabilize the vertebral body, and reduce screw and rod breakage and loss of correction.
OBJECTIVE: To evaluate the long-term effects of pedicle screw placement fixation through the injured vertebra in the repair of thoracolumbar fracture.
METHODS: From February 2010 to February 2012, 36 patients with thoracolumbar fracture, who were treated in the Department of Orthopedics, Guangzhou Panyu District Second People’s Hospital, were selected. They were 
treated by vertebral pedicle screw placement fixation. Height ratio of preoperative injured vertebral leading edge was averagely 36%. Kyphosis angle (Cobb angle) was 25°. Sagittal diameter of the center of the vertebral canal was 60%. Nerve function was classified according to Frankel classification: grade A, 2 cases; grade B, 6 cases; grade C, 10 cases; grade D, 9 cases; grade E, 9 cases. The height ratio of injured vertebra, kyphosis angle (Cobb angle), sagittal diameter of the center of the vertebral canal and Frankel classification of nerve function were compared before and after treatment.
RESULTS AND CONCLUSION: The postoperative follow-up was 3-3.5 years. Pain was obviously alleviated postoperatively in 36 patients. Average height ratio of injured vertebra was 95%. Kyphosis angle (Cobb angle) was 3.5°. Sagittal diameter of the center of the vertebral canal was 96%. Significant difference was found in the above indexes before and after treatment (P < 0.05). Postoperative neurologic recovery: grade A in 1 case, grade B in 2 cases, grade C in 3 cases, grade D in 4 cases, and grade E in 26 cases. Postoperative fractures were reset. Complications such as breakage, loosing or correction loss were not found. These findings suggest that pedicle screw placement fixation through the injured vertebra in the repair of thoracolumbar fracture can make a satisfactory reduction, enhance the pressure stability of the spine, reduce the internal fixation of fracture and vertebral height loss, and have good long-term effects, indicating that the implant and host have good biocompatibility.
