The effects of tibia profile, distraction angle, and knee load on wedge instability and hinge fracture: A finite element study

Highlights • This study aims to investigate the contouring effects of a TomoFix plate on the biomechanical behaviors of an osteotomized tibia-plate-screw construct. • The use of a lag screw to pull the distally osteotomized segment toward the plate significantly decreases the fracture risk of the di...

More Information
Summary:Highlights • This study aims to investigate the contouring effects of a TomoFix plate on the biomechanical behaviors of an osteotomized tibia-plate-screw construct. • The use of a lag screw to pull the distally osteotomized segment toward the plate significantly decreases the fracture risk of the distracted wedge within the postoperative period. • A precontoured plate is recommended in the case that the proximal tibia is highly concave and the distraction angle is insufficient to stretch the tibial profile.
