Experimental Analysis of Strength Characteristics of Devices for Acetabular Osteosynthesis
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.
