Abstract:
Objective To investigate the feasibility of manual reduction with inverse shift for pronation-extorsion trimalleolar fracture by applying the finite element method combined with clinical experience. Methods Based on CT images and anatomical features of bone, ligaments and other tissues as well as material parameters, a normal ankle model with completed muscles and bones for a Chinese young male was established. According to the related characteristics of the pronation-extorsion trimalleolar fractures, fracture was simulated in the proper position to make osteotomy model. The finite element model of pronation-extorsion trimalleolar fractures was thus established and then applied with mechanical loading to simulate manual reduction with inverse shift. Results The established finite element model of pronation-extorsion trimalleolar fractures was effectively restored by the displacement loading. Conclusions The finite element analysis on pronation-extorsion trimalleolar fractures by inverse shift maneuver could further prove the feasibility, effectiveness and scientificity of manual reduction with inverse shift based on clinical experience.
