Radiographs are assessed for ulnar variance and to exclude other possible osseous or ligamentous pathology. Arthrographic findings are diagnostic for TFCC tears; however, not all tears are symptomatic, and further investigation may be necessary. Additional diagnostic modalities could include arthroscopy and MRI. Differential local anesthetic injections can also aid in the diagnosis.
