To evaluate cases of traumatic spondylolisthesis of the axis and describe them in relation to epidemiology, classification, neurological deficit, healing time and treatment method.
A retrospective analysis of the medical records of patients treated between 2002 and 2010 at IOT-FMUSP.
pars interarticularis fracture of C2.
68% were male patients, with a mean age of 39.1 years. We used the classification by Effendi, modified by Levine-Edwards. Type I fractures were observed in five patients (31.2%) and type II in eight patients (50%). Only three patients (18%) had type IIa fracture. There were no cases of type III. Mechanism: Eight car accidents and four falls. Other mechanisms: being run over, and diving accidents. Treatment with halo traction was used in eleven patients, using minerva cast and halo-cast. Healing time: 3.6 months. Follow-up time: 9.6 months.
In general, hangman fracture has a good prognosis, which is confirmed by our results. There was no need for surgery in any of the cases. The incidence of neurological deficit is low. No patient had unstable fracture (type III).
This paper suggests that traumatic spondylolisthesis of the axis continues to be an injury that is successfully treated by conservative treatment in most cases. Level of Evidence -IV, Case series.
评估枢椎创伤性滑脱病例,并从流行病学、分类、神经功能缺损、愈合时间及治疗方法等方面进行描述。
对2002年至2010年在IOT-FMUSP接受治疗的患者病历进行回顾性分析。
C2关节突骨折。
68%为男性患者,平均年龄39.1岁。采用经Levine-Edwards修改的Effendi分类法。观察到5例(31.2%)I型骨折,8例(50%)II型骨折。仅3例(18%)为IIa型骨折。无III型病例。受伤机制:8例车祸,4例跌倒。其他机制:被车辆碾压、潜水事故。11例患者采用头环牵引治疗,使用密尔沃基支具和头环石膏。愈合时间:3.6个月。随访时间:9.6个月。
总体而言,绞刑者骨折预后良好,我们的结果证实了这一点。所有病例均无需手术。神经功能缺损发生率低。无患者发生不稳定骨折(III型)。
本文表明,枢椎创伤性滑脱在大多数情况下仍是一种可通过保守治疗成功治愈的损伤。证据级别 - IV,病例系列。
