Park KH, Park HW, Oh CW, et al. - Researchers constructed a novel unicortical pin and analyzed it in a biomechanical study to overcome the high risk of infection associated with the use of the conventional bicortical pin for temporary external fixation. For the purpose of comparison, a bicortical pin was applied. Using a monoplanar configuration, a fracture gap model was stabilized. Using a servo-hydraulic testing machine, both the unicortical pins (Uni group) and bicortical pins (Bi group) had undergone axial compressive and torsional load testing. They documented stiffness, load to failure, and mode of failure. This study’s findings demonstrate that the newly designed unicortical pin significantly increased fracture stability under both axial compressive and torsional loads in comparison with the conventional bicortical pin. When performing external fixation of fractures, the unicortical pin can be considered an alternative biomechanical solution to obtain adequate stability.
