Abstract
A device for marking cutaneous landmarks as a means of identifying under x-radiography pathological deep structures of the small bones of the foot that comprises affixing a radiopaque material to an adhesive tape and placing the radiopaque material over a cutaneous landmark on a patient's foot and then x-raying the highlighted area. The radiopaque material is formed into any one of a variety of shapes, such as a circle, triangle or square, so as to provide a marker that completely encompasses the cutaneous landmark. A series of such markers is affixed to a roll of tape with an adhesive backing, or provided in pre-cut form, for ease of dispensation and attachment to the patient's foot.
