Metatarsal geometry and the indication for stress fractures

摘要

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.
