A bone scan is often used these days to make the diagnosis of bony injury where x -rays are normal but the history and examination findings suggest otherwise. This requires an injection of a radio isotope dye into the arm which is then taken around the body by the blood stream.
Sometimes specific types of imaging (CAT or MRI scans) of the particular area are performed to assess the extent of the damage to the bony and cartilaginous surfaces. This may allow us to see bony fractures which have become unstable and formed loose bodies in the past.
This usually means temporarily removing the athlete from their provocative activity and embarking on an appropriate rehabilitation program before the stress “crack” in the bone becomes anything more major. Ultrasound scans are also used more and more these days to help determine the nature of soft tissue injuries such as acute or chronic Achilles (bottom of calf), patella (front of knee), tendon injuries and rotator cuff tears in the shoulder.
These are a relatively inexpensive form of investigation but can provide very useful information with regard to diagnosis and severity of injury. The most advanced (and expensive) form of imaging used in sports medicine is the MRI scan.
Injecting a contrast material that contains iodine can help highlight sections of your circulatory system to make them visible on X -rays. Barium, a contrast medium delivered in a drink or an enema, can help reveal problems in your digestive system.
X -rays will pass through the body and produce an image on the specialized plate below. Ask your doctor or nurse to provide you with specific instructions.
You may swallow the contrast medium or receive it as an injection or an enema. The machine produces a safe level of radiation that passes through your body and records an image on a specialized plate.
However, if you're injected with contrast medium before your X -rays, drink plenty of fluids to help rid your body of it. Call your doctor if you have pain, swelling or redness at the injection site.

Fell down 5 stairs and hurt lower leg pretty bad. However after 6 days it has gotten a lot more painful, and black and blue and I can't really put any weight on it.
Misalignment can put excessive force on parts of the joint and accelerate arthritic changes. Narrowing of this joint space is the best sign of the extent of knee arthritis.
