Abstract

A finite element analysis is carried out to find the optimum position of the pin placement of mini fixator in Lapidus procedure in the treatment of Hallux Valgus. Various parameters are considered for analysis like diameter of the pin, positioning of the pin from the fracture site, number of pins effecting the stability of the fixation device and fusion site, rail distance from the fusion site, effect of width and length of the rail, effect of fusion angle and effect of pin angle positioning in fusion the joint by using FEMLAB 2.3 for both modeling and analysis. A 2D model is constructed with the bone joint consisting of first metatarsal and cuneiform along with the fixation device. The dimensions of the model are taken similar to a prototype model of the foot. Static analysis was done to find the displacement between the first metatarsal and cuneiform with the application of the mini fixator.
