Method of finite element modeling was used for mathematic modeling of pelvic fractures and various variants of anterior and posterior pelvic ring fixation with reconstructive plates, cannu- lated sacroiliac screws and pelvic screws. Four most common types of fracture were simulated. Stress-deformed conditions of metal constructions for every type of fracture and variant of its fixation were determined. Study results enabled to determine the optimum fixation techniques in various types of fractures, to confirm the significance of both anterior and posterior pelvic stabilization, as well as to substantiate the possibility of early rehabilitation with full weight bearing in such severe patients
