This title is directed primarily towards health care professionals outside of the United States. This valuable clinical reference alerts practitioners to potentially serious indicators of pathology in their patients, such as cancer, tuberculosis (TB), or other conditions.

It's an ideal, on-the-spot resource for anyone involved in the care of patients with musculoskeletal conditions.
