Answer

There are also data to suggest that the so-called ulnar fovea sign may be a clinically useful test for defining ulnar-sided wrist pain in cases of foveal disruption of the distal radioulnar ligaments and ulnotriquetral ligament injuries. [8] In a retrospective study of 272 patients who had undergone wrist arthroscopy, 90 cases were of foveal disruptions and 68 were of ulnotriquetral ligament injuries. Of these patients, the ulnar fovea sign was positive in 156. The sensitivity of the sign was 95.2%, and the specificity was 86.5%. [8]
