Three common elementary acetabular fractures, i.e. transverse fracture, fractures of anterior and posterior column, were simulated on plastic pelvis models. Comparative testing of three types of osteosynthesis - with reconstructive plate, cannulated screws and pins or using our new CITO flattened fine thread screws 3 mm in diameter were performed under similar conditions. Strength of cannulated screw and CITO screw was evaluated. Testing was performed on servo-hydraulic universal testing machine. The most stable fixation was achieved with cannulated screw and CITO screw. The latter was inferior in strength however ensured required rigid fixation.
