髋臼横断骨折双柱内固定的生物力学分析
Biomechanical analysis of double-column internal fixation on acetabular transverse fracture
摘要
Abstract
BACKGROUND: The key of pelvic and acetabular fracture treatment is accurate fracture reduction and stable internal fixation.OBJECTIVE: To analyze the biomechanical characteritics of three kinds of double-column internal fixation operation foracetabular transverse fracture in order to find the most stable method.METHODS: Anisotropic pelvic fracture model was established, and based on the maximum displacement, the maximumequivalent stress and other comprehensive evaluation indexes, the biomechanics of double-column screw, anterior-columnscrew and posterior-column plate, double-column plate on the standing position were analyzed.RESULTS AND CONCLUSION: Finite element analysis showed that the maximum displacement of double-column screw was1.827 mm, maximum equivalent stress was 26.589 Mpa; the maximum displacement of screw and posterior-column plate was2.080 mm, maximum equivalent stress was 106.04 Mpa; the maximum displacement of double-column plate was 2.987 mm,maximum equivalent stress was 200.37 Mpa. The most stable method is double-column screw and the last one is double-columnplate.关键词
