摘要:

背景:临床上常应用伤椎相邻节段置入椎弓根钉内固定的方式修复胸腰椎骨折脱位,伴随着疾病发生率的升高,同时发现众多的问题,比如内固定器械松动、断裂等。
目的:对比经伤椎与跨节段置椎弓根钉内固定修复胸腰椎椎体骨折脱位的效果。
方法:选择解放军第474医院2013年2月至2014年5月收治的100例胸腰椎骨折脱位患者,按照简单随机法分为两组,每组50例。对照组患者进行跨节段椎弓根螺钉置入内固定治疗,观察组患者进行经伤椎椎弓根钉置入内固定治疗。对比观察两组患者的影像学参数。
结果与结论:对两组患者的椎管面积改善值、内固定失效率进行对比分析,差异均有显著性意义(P < 0.05),观察组优于对照组。治疗后12个月,两组患者的椎体前缘高度比值高于治疗前,Cobb角低于治疗前(P < 0.05)。提示与跨节段置钉相比,经伤椎置钉短节段内固定修复胸腰椎椎体骨折脱位的效果较为理想,安全性较高,在保证固定强度的同时更加符合生物力学特点。

Abstract:

BACKGROUND: The clinical treatment of thoracolumbar fractures and dislocation of the patients can be treated with pedicle screw fixation through adjacent vertebral segments. With the increased incidence of disease, many problems were found such as fixator loosening and breakage.
OBJECTIVE: To compare the effectiveness of vertebral pedicle screw fixation versus cross-segment pedicle screw fixation for thoracolumbar vertebral fracture and dislocation.
METHODS: 100 patients with thoracolumbar vertebral fracture and dislocation were chosen in the 474 Hospital of Chinese PLA from February 2013 to May 2014. The patients were randomly assigned to two groups (n=50). Patients in the control group were treated with cross-segment pedicle screw fixation, and those in the observation group were treated with the vertebral pedicle screw fixation. Parameters of imaging were compared and observed.
RESULTS AND CONCLUSION: Significant differences in the spinal canal area improvement value and internal fixation failure rate were detected between the two groups (P < 0.05), and the observation group was better than the control group. The height ratio of anterior border of the vertebral body was higher at 12 months after treatment than that pretreatment, but Cobb angle was lower than pretreatment (P < 0.05). These data indicate that compared with cross-segment pedicle screw fixation, vertebral pedicle screw short-segment fixation for
thoracolumbar vertebral fracture and dislocation obtains more ideal outcomes and higher safety. It is more in line with biomechanics at the same time ensuring the fixing strength.
