The aim of this study was to assess the biomechanics of four different screw configurations used for the fixation of tongue-type IIC calcaneal fractures. Methods: Identical osteotomies, recapitulating a type IIC injury, were created in synthetic calcaneus specimens using a saw. The specimens were randomly assigned to one of the four fixation groups (n ¼ 7 per group): two divergent screws, two parallel screws, two parallel screws plus one screw axially oriented toward the sustentaculum tali, and three parallel screws. A load test was performed on all of the groups, and the specimens were then tested using offset axial loading until 2, 4, and 5 mm of fracture displacement occurred. Results: Mean force values for the three–parallel screw construct at 2-, 4-, and 5-mm fracture displacements were found to be significantly higher compared with those for the other groups. Conclusions: The use of a three–parallel screw construct seems to provide more stability in the treatment of tongue-type IIC fractures. | Permalink : | https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= |
