[Indications to complementary radiological exams for pathologies of the shoulder].
Plain Xrays should stay in pole position for the evaluation of shoulder's pathologies. They allow frequently to make a diagnosis of the lesion. Indications to complementary exams are well established. CT-scan and MRI have to give responses to precise questions, which then will permit to manage the treatment. CT-scan allows to evaluate accurately bone structures. It is very useful for analysing complex fractures of the proximal humerus. It allows also to evaluate the amount of glenoid wear to correct before implanting a prosthesis. Arthro-MRI is used to study soft tissues, cartilage and bone. Therefore, it is the first choice exam to evaluate the rotator cuff tendons, as well as the labrum and ligaments in case of shoulder instability.
