| ［摘要］ 目的 探讨椎弓根钉棒内固定治疗胸腰段骨折脱位的临床疗效。方法 选择50例胸腰段骨折脱位患者，采用椎弓根钉棒内固定治疗，观察内固定前、内固定术即时及随访12个月时脊髓损伤恢复情况，病椎前后缘高度百分比、Cobb角的恢复及并发症发生情况。结果 50例胸腰段骨折脱位患者均获得随访，随访时间为12个月。内固定后即时、随访12个月时，病椎的前后缘高度百分比较内固定前明显提高(P<0.01)，Cobb角较内固定前明显降低(P<0.01)，而内固定后即时与随访12个月比较，病椎前后缘高度百分比、Cobb角比较差异无统计学意义(P>0.05)。内固定前脊髓损伤主要分布于B级和C级，内固定后即时、随访12个月时主要分布于D级和E级，内固定后即时、随访12个月时脊髓损伤分布与内固定前比较差异有统计学意义(P<0.01)，而内固定后即时与随访12个月时的脊髓损伤分布差异无统计学意义(P>0.05)。结论 针对胸腰段骨折脱位患者,采用椎弓根钉棒内固定术治疗，能有效地恢复病椎的高度，促进受损脊髓神经的功能，且疗效稳定，值得临床借鉴。 |

| ［Abstract］ Objective To investigate the clinical curative effect of treating thoracolumbar fracture and dislocation with pedicle screw rod internal fixation.Methods Fifty patients with thoracolumbar fracture and dislocation were collected, who were treated with pedicle screw rod fixation. The condition of spinal cord injury recovery, the percentage of anterior and posterior edge height of disease vertebral, the occurrence of complications and the condition of Cobb angle recovery were observed before internal fixation, at immediate after internal fixation and at a followed-up of 12 months.Results Fifty patients were followed up for 12 months. The percentage of anterior and posterior edge height of disease vertebrae at immediate after fixation, at a followed-up of 12 months were increased evidently than those before fixation(P<0.01), the Cobb angle was decreased obviously than before fixation(P<0.01). Between the time points at immediate after fixation and at a followed-up of 12 months, the percentage of anterior or posterior edge height of disease vertebra and Cobb angle had no significant differences(P>0.05). Before internal fixation, the spinal cord injury mainly distributed at B level, C level, but at immediate after internal fixation and at a followed-up of 12 months after internal fixation, they distributed mainly in D level and E level, anterior spinal cord injury distribution at instant after internal fixation and at a followed-up of 12 months after internal fixation had significant difference from that before internal fixation(P<0.01), and between the time point at immediate after internal fixation and the time point at 12 months followed-up after internal fixation, the distribution of spinal cord injury had no significant differences(P>0.05).Conclusion For patients with thoracolumbar fracture and dislocation, pedicle screw rod internal fixation can effectively restore vertebral height and promote injured spinal nerve function. |
