Abstract :Objective: Dynamic compression plate (DCP) and limited contact dynamic compression plate (LC- DCP) are used for open reduction internal fixation of radial shaft fractures. They are distinguished from other systems by the principles of reduced plate-bone contact and dynamic compression. This study aims to compare the stress and deformation under axial forces in DCP and LC-DCP. Materials and Methods: The DCP and LC-DCP were applied to 16 artificial radius bones by an experienced surgeon fixed at the distal and proximal of the fracture line with three cortical screws for each. In axial loading tests, the amount of force applied to the sawbones with DCP and LC-DCP and the amount of extension were calculated. Results: DCP and LCDCP fixation plates on forearm fracture models were found to be statistically similar in terms of the applied force and displacement (p=0.161). Conclusion: The study showed both implant types (DCP and LC-DCP) could be appropriate for the fixation of forearm fractures and osteotomies due to no mechanically significant difference under axial loadings. The plate to be applied can definitely be chosen considering the cost of the plate and the anatomical requirements.
