Abstract:
The stress fracture is often resulted from forced march, heel-and-toe walking race, trudge over a longdistance etc. The stress fracture in metatarsal bone is very common. After analysis of bearing-force onmetatarsal bone, the feet are simplified as weight-bearing-cantilever beam structure, while the metatarsalbone as lever units which support the bending cantilever. 16 metatarsal bones were taken from freshcadavers of normal Chinese adults. TYPE 2H cantilever stress teeting machine was used for the experiment.This study analyzes the injury mechanism of stress fracture theoretically, the defines limit of stress fractureof the metatarsal bone, and makes biomechanical analysis for the fracture types. This experiment providesthe data and materials for prevention and diagnosis of stress fracture and the possibility of methods andpaths for stress fracture experiment of the biomaterials.
