Short summary
Finite element analysis reveals that even after recovery from a fifth metatarsal (MT5) fracture, significant biomechanical changes persist in the foot during the running stance phase compared to healthy individuals.

Key points
- Finite element analysis reconstructed pre-fracture foot kinematics using observed bone displacements.
- 21 subjects with prior MT5 shaft stress fractures were compared to 21 healthy controls.
- Post-rehabilitation, MT5 fractures caused significant changes in foot biomechanics during running stance.
- These biomechanical impacts persist even after cast immobilization and recovery.

Abstract
The purpose of this study is to restore the before fracture kinematic state by using the observed foot bone displacements as boundary conditions for finite element (FE) analysis. Secondly, this study aims to compare the biomechanical changes of the foot before and after a metatarsal (MT) fracture using this method. A total of 21 subjects had previously experienced a shaft stress fracture of the MT5 in the six months before the collection of experimental data. All patients received treatment through the use of cast immobilization for duration of 4-6 weeks. After the subject's recovery, we obtained gait biomechanical data. At the same time, we also obtained gait data from 21 healthy subjects as the control group. This study found that when a fracture of the MT5 occurs, even after rehabilitation, there is a significant impact on the metatarsal.
