摘要

This paper addresses the use of composite bone plates in healing long-bone fractures such as transverse fractures of the tibia using finite element analysis, that takes into consideration contact conditions and material property variations of calluses in relation to the healing period. For the time-varying properties of calluses in relation to the healing period, stepwise material properties were imposed on the callus part based on the time elapsed, and the loading conditions were coupled with the callus properties based on the length of the healing period. The strain distributions at the fracture site were calculated according to the stacking sequence of the bone plate and healing time. The analysis results showed that composite bone plates with stacking sequences of [0]_(12T) for the Kevlar/BCP composites generated the most appropriate strain distributions at the fracture site during the early healing process.
