Answer

Radiographs of the elbow reveal abnormal anatomy, such as a valgus deformity, bone spurs or bone fragments, a shallow olecranon groove, osteochondromas, and destructive lesions (eg, tumors, infections, or abnormal calcifications). If there is a history of trauma or arthritis, a cubital tunnel projection radiograph should be obtained to exclude medial trochlear lip osteophytes. If a supracondylar process on the medial aspect of the humerus is suspected, an elbow radiograph should be obtained 5 cm proximal to the medial epicondyle.

Radiographs of the wrist reveal fractures of the hook of the hamate, dislocations of the wrist bones, and, to a lesser extent, soft-tissue masses and calcifications.
