Understanding tests used to detect bone problems
Bones can be damaged by fractures or other injuries, as well as irritations. The damage can also be caused by diseases, such as osteoarthritis, infections or cancer. Various tests and examinations can help to find out what is causing problems in the bones and joints.
Before more specific bone examinations are performed, preliminary tests are typically done, which typically include a detailed discussion with your doctor, a physical examination, and blood tests if necessary. These preliminary tests are used to help decide whether any further diagnostic testing is a good idea and to prevent any unneeded treatment. The tests are also important to correctly interpret the results of any scans.
For instance, an x-ray image can easily detect a bone fracture, but it doesn't give doctor much information about back pain. Modern, high-resolution equipment can often detect changes in bones, tendons or cartilage that don’t have any medical significance. Once they have been detected, these kinds of changes can easily result in unneeded treatment, though.
Bone tests and examinations may have side effects or involve exposure to radiation as well. So there are good reasons to be cautious about these kinds of diagnostic procedures.
