摘　　要：骨折内固定术是治疗骨折的主要手段。由于患者骨密度低，手术过程中先导孔质量不佳，选用不合理的螺钉结构及螺钉表面特性，置钉扭矩、置钉角度以及螺钉与骨孔的适配性未进行精准控制都将引起螺钉松动、失稳，最终导致骨折内固定术失败。本文从骨密度、先导孔质量、螺钉结构、置钉扭矩大小、螺钉和先导孔的适配性等方面，对骨折内固定中螺钉稳定性影响因素的研究现状进行综述，总结提升螺钉稳定性的方法，为临床骨折治疗提升螺钉稳定性，改善提高内固定治疗手术效果提供参考。Internal fixation is one of the most important treatments for fractures. The stability of screws in internal fixation can be influenced by bone mineral density, quality of pilot holes, improper structure and surface characteristics of screws chosen, insertion torque, insertion angle, and screws unfit for the bone holes. Internal fixation of fractures can fail due to the instability of screws. This paper, on the basis of a comprehensive review of the studies on all the above factors influencing the screw stability, proposes effective methods to enhance screw stability so as to improve surgical outcomes of fracture internal fixation.
