Objective To evaluate biomechanical properties of the sactciliac screw by three-dimensional finite element for providing theory basis to choice the internal fixation ways of the sacroiliac joint fracture dislocation.Methods Establishing finite element models of simple sacroiliac joint dislocation(A model),and the sacroiliac joint dislocation and pubic symphysis separation(B model).They were fixed using both single S1 screws(Ⅰ class fixed) and S1,S2 double screws(Ⅱ class fixed).Four models(AⅠ,AⅡ,BⅠand BⅡ) were loaded and analysised nonlinearly by the finite element.Results ①Comparative results of the maximal displaxement: AⅡBⅡAⅠ normal pelvicBⅠ.Comparative results of the greatest stress: BⅠAⅠ BⅡ AⅡnormal pelvic.②Stress convective of the S1 screw: the stress of the S1 screw concentrately distributes,and the peak appears in the places passing the sacroiliac joints.Conclusion ①After anatomical reattachment of the pure fracture dislocation of sacroiliac joints,pelvic ring fixed by S1 screw the can obtain reliablestability.Thus,no significance to take a risk to insert the S2 screw.②When the sacroiliac joint fracture dislocate and the pubic symphysis separate,the posterior ring fixed purely by S1 screw can't restore the stability.The best fixation is the anterior ring fixed by steel plates and the posterior ring fixed by the S1 screw.③The S1 screw easily produces fixed fatigue and breakages in the places passing the sacroiliac joints.
