椎弓根拉力螺钉内固定治疗Hangman骨折

探讨应用椎弓根拉力螺钉技术治疗Hangman骨折的临床疗效.方法 对12例Hangman骨折患者经颅骨牵引获得复位后,行C2椎弓根拉力螺钉内固定术治疗.术后行X线片检查观察骨折复位及愈合情况.结果 手术时间50～90min,失血量100～300ml.术中无脊髓神经损伤,骨折复位满意.12例均获随访,时间3~36个月.骨折完全愈合,无迟发畸形.2例脊髓神经损伤者术前Franke1分级为D级,术后3~6个月均恢复至E级.结论 C2椎弓根拉力螺钉技术治疗Hangman骨折,复位满意,固定可靠,疗效满意.

Pedicle lag screw fixation in the treatment of Hangman's fracture

Objective To study the clinical outcomes of Hangman′s fracture treated by using pedicle lag screw fixation.Methods 12 patients with Hangman′s fracture were recruited.All patients achieved reduction by skull traction,and fixed with C2 pedicle lag screw.X-ray was performed during the follow-up to observe fracture reduction and healing process.Results The operation time was 50~90 minutes,and the blood loss was 100~300 ml.And intraoperative no spinal nerves injury the reduction of the Hangman′s fracture was satisfied.No postoperative complications were confirmed.12 cases were followed up for 3~36 months.All got healing without deformity.2 cases of Frankel D were restored to E in 3~6 months.Conclusions Pedicle lag screw fixation provides good reduction and stability to Hangman′s fracture.It is a less trauma,safe and effective method in the treatment of Hangman′s fracture.
