Variable methods have been introduced for reduction of the zygomatic fractures. The Dingman elevator is used widely to reduce these fractures but is inappropriate in certain types of fractures which require atypical traction vectors. We introduce and examine an alternate method of reducing zygomatic fractures using wire and hook traction.
A retrospective study was performed for all zygomatic fracture patients admitted between 2008 and 2014. Medially rotated fractures were reduced by using a wire looped through an intermaxillary screw secured on the medial side of the zygoma. Laterally rotated fractures were reduced using a hook introduced through an infrazygomatic skin incision.
No accidental bleeding or incomplete reduction was observed in any of the cases. Postoperative imaging demonstrated proper reduction immediately after the operation. Follow-up computed tomography study at 1 month after operation also demonstrated proper reduction and healthy union across the previous site of fracture.
The hook and wire method allowed precise application of traction forces across zygomatic fractures. The fractured bone fragment could be pulled in the direction precisely opposite to the vector of impact at the time of trauma. Soft tissue damage due to dissection was minimized. In particular, this method was effective in reducing rotated bone fragments and can be an alternative option to using the zygoma elevator.
已引入多种方法来复位颧骨骨折。丁曼骨膜分离器被广泛用于复位这些骨折,但在某些需要非典型牵引向量的骨折类型中并不适用。我们介绍并研究了一种使用钢丝和钩子牵引来复位颧骨骨折的替代方法。
对2008年至2014年间收治的所有颧骨骨折患者进行回顾性研究。对于向内旋转的骨折,通过将钢丝绕过固定在颧骨内侧的上颌间螺钉来进行复位。对于向外旋转的骨折,通过经颧下皮肤切口插入的钩子来进行复位。
所有病例均未观察到意外出血或复位不完全的情况。术后影像学检查显示术后立即实现了正确复位。术后1个月的随访计算机断层扫描研究也显示骨折部位复位良好且愈合正常。
钩子和钢丝方法能够精确地对颧骨骨折施加牵引力。骨折骨块能够被精确地朝着与创伤时撞击向量相反的方向牵拉。因解剖导致的软组织损伤降至最低。特别是,这种方法在复位旋转的骨块方面效果显著,并且可以成为使用颧骨骨膜分离器的替代选择。
