皮质骨螺钉内固定技术在颏部骨折中的应用

Use of cortical (lag) screws in internal fixation of mental fractures

目的:对颏部骨折应用皮质骨螺钉内固定的效果进行评价。方法:对12例颏部单线骨折采用皮质骨螺钉内固定术进行治疗,术后观察3～6个月。结果:12例患者中,10例应用1枚螺钉固定,2例应用2枚螺钉固定。术后伤口均一期愈合,咬合关系良好,张口运动正常。结论:颏部骨折应用皮质骨螺钉固定,可达到较为理想的加压和稳定效果。皮质骨螺钉技术简单,操作方便,术中避免了弯制接骨板以适应复杂的下颌骨外形的步骤,缩短了手术时间,并可在骨折线上产生压应力,促进骨折愈合。

PURPOSE: To evaluate the clinical results of cortical (lag) screws in internal fixation of mental fractures. METHODS: 12 patients with single linear mental fracture underwent internal fixation using cortical screws. The patients were followed up for 6 to 9 months after fixation. RESULTS: Of 12 cases, 1 cortical screw was used in 10 cases, and 2 cortical screws were used in 2 cases. The wound healed primarily postoperatively. The patients had normal occlusion and mouth opening. CONCLUSION: Fixation of mental fracture using cortical screw can achieve good stability and appropriate compression. The technique is simple and easily performed, which avoids the bending of the reconstruction plate to adapt to the complex configuration of the mandible, reduce the surgical time, and promote the healing process by producing stress in the fracture lines.
