Abstract :
The present study analyzes the effect of changes in the geometry of the metatarsals (MT) on the incidence of MT stress fractures. Patient specific MT geometries were extracted from x-rays. Stresses in MT´s were computed using bending theory and compared with the incidence for stress fractures. Results showed that MT cross-sectional area plays a profound role in stress fracture incidence.
