Common bone injuries in sport include epiphysitis, fractures, and stress fractures. Although bone is made of a hard material, it is relatively rigid making it strongest in resisting compression and weakest in resisting shear forces. Sensation is confined to the periosteum, so unless this structure is damaged, disorders of the bone can be painless. However, pain is severe if the periosteum is even slightly damaged (e.g. by a stress fracture).
