This is a prospective cohort study with a historical control group involving patients >=50
years-old with an acute (<3 weeks) Anderson & D'Alonzo type II dens fractures identified on
cervical spine CT scan. This will be a pilot efficacy trial to compare treatment of odontoid
fractures with 8 weeks of treatment with a PTH analog (abaloparatide) + hard collar
immobilization in comparison to historical treatment with hard collar immobilization alone.
