What Does a Bone Spur Look Like?

A bone spur appears as a tiny, pointed growth on a bone, according to MedicineNet. Bone spurs, which are typically only treated when pain occurs, are generally only visible through radiologic testing such as X-rays, an MRI scan, CT scan and ultrasound imaging. Caused by a local inflammation such as arthritis or tendonitis, bone spurs typically develop near areas of injury or inflammation of cartilage and tendons.
