颈前路加压螺钉在齿状突骨折手术治疗中的应用和临床疗效

Application and Clinical Efficacy of Anterior Compressive Screw System Fixation in the Treatment of Odontoid Fracture

目的探讨颈前路加压螺钉在齿状突骨折手术治疗中的应用和临床疗效。方法2006年10月～2009年12月,对23例II型齿突骨折在X线监测下施行经颈前路单枚加压螺钉内固定术。观察手术时间、术中出血量、术后骨折愈合以及颈部活动情况。结果手术时间75～120min,平均95min。术中出血50～110ml,平均70ml。术中无一例发生副损伤。所有患者获得6～32个月的随访,平均16个月。23例骨折均正常愈合;23例骨折愈合后颈椎活动均恢复正常。结论颈前路加压螺钉内固定技术有固定简单可靠、损伤少、愈合率高等优点,是一种较理想的治疗II型齿状突骨折的手术方法。

Objective To study the application and clinical efficacy of anterior compressive screw system fixation in the treatment of odontoid fracture. Methods From October 2006 to December 2009, 23 cases of type II odontoid process fracture were fixed internally by an- terior approach with single compressive screws under the monitor of X-ray. The operation time, blood loss, fracture healing and the cervical motion function were evaluated respectively. Results The operation time was from 75 to 120 minutes （average 95 minutes）. The blood losses during operation were from 50 to 110 ml （average 70 ml）. During a follow up of 6 to 32 months （average 16 months ）, all the fractures were healed without complication. The cervical motion function of 23 cases recovered completely after fracture healing. Conclusion It is suggest- ed that the anterior compressive screw system fixation has the advantages of easy and safe fixation, hypo-injury, high bone fusion rate and so on, this treatment of type II odontiod fracture is confirmed to be ideal.
