不稳定Hangman骨折的手术治疗

Objective To investigate the clinical effects of pedicle screw fixation in the treatment of unstable Hangman fractures. Methods From October 2001 to April 2006, 15 patients with the unstable Hangman fractures were treated by the pedicle screw fixation after skull traction and reduction through posterior cervical approach. By Levine-Edwards classification, there were 3 cases of Ⅱ type, 4 cases of ⅡA type, 8 cases of Ⅲ type. Results The mean follow-up time was 17 (3 to 30) months. Six cases of Grade D by Frankel classification recovered to Grade E. Postoperative X-rays revealed bony union in all cases. No screw loosening or obvious functional limitation of the cervical vertebrae was found. In the cases of incomplete reduction, C2, 3 fixation was performed for patients without severe dislocation, and additional CA fixation with lateral mass screw was supplemented for patients with serere dislocation. Conclusion Posterior pedicle screw fixation of C2,3 or C2-4 is an effective and safe method for treating the unstable Hangman fractures.

目的:探讨Hangman骨折的临床、影像学特点及治疗。方法:回顾分析14例Hangman骨折患者的临床资料,男13例,女1例;平均年龄31岁。根据Levine-Edwards的X线分型:Ⅰ型1例,Ⅱ型7例,ⅡA型3例,Ⅲ型3例。3例合并神经症状。3例采用后路C2椎弓根螺钉固定;8例前路手术,行C2,3椎间盘切除及植骨,颈前路钢板固定;3例后路复位,行前路C2,3椎间盘切除植骨钢板内固定术。结果:14例全部获得5~63个月随访,术后3个月均获得骨性融合,颈椎序列良好,颈椎伸屈侧位片显示颈椎稳定,无内固定松动、脱出及断裂,无椎动脉损伤、神经损伤、脑脊液漏及切口感染等手术并发症。3例脊髓损伤神经功能恢复良好。结论:手术治疗Hangman骨折安全有效,Ⅱ型、ⅡA型、Ⅲ型应及早手术治疗,颈椎前路融合加钢板内固定术可使Hangman骨折获得良好的即时稳定性,有利于患者早期下床活动,不影响颈椎活动度,是Ⅱ型、ⅡA型、Ⅲ型Hangman骨折较好的手术方法。     

枢椎椎弓根拉力螺钉内固定技术治疗Hangman骨折

目的：探讨枢椎椎弓根拉力螺钉内固定治疗Hangman骨折的适应证,并评价其临床应用价值。方法：2003年7月至2007年6月共收治Hangman骨折患者28例。Levine-Edwards分型：Ⅰ型6例,Ⅱ型17例,Ⅱa型5例。脊髓功能Frankel分级：D级3例,E级7例。取C2侧块中点为进针点,根据C2椎弓根的内缘和上缘走行确定进针方向,向头侧倾斜25°～30°,向中线倾斜30°～35°。应用测深器确定螺钉长度,一般为24～30mm。结果：术中未发生椎动脉损伤及其他并发症。术后所有患者随访4～48个月,平均20个月。神经功能恢复正常,所有骨折均在术后6个月愈合,颈椎活动范围接近正常,未出现颈椎不稳和螺钉松动。结论：单节段枢椎椎弓根拉力螺钉内固定技术可使Hangman骨折获得良好的即刻稳定性,且较少干扰上颈椎的生理功能。其适应证应限于骨折可复位的病例。
