In this video, I'm going to show you how to examine for the fovea sign in the assessment of TFCC lesions. [Music] Check out our online courses now; the link is in the video description. Hi, and welcome back to PhysioTutors.

The triangular fibrocartilage complex, abbreviated as TFCC, consists of the articular disc (meniscus homologue), the dorsal and palmar radial ulnar ligaments, the ulnolunate and ulnotriquetral ligaments, and the extensor carpi ulnaris tendon sheath.

As a center of forearm rotation, the TFCC plays a key role in stabilization, rotation, translation, and load transmission to the wrist and acts as an essential pivot point. Due to its anatomical location, as well as its involvement in the key functions of rotation and load bearing, it is

highly prone to injuries and additional wear. Schmo et al. (2016) examined the fovea sign regarding its clinical accuracy in 908 patients suspected to have TFCC lesions. The authors found a sensitivity of 73% and a specificity of 44%.

Results varied slightly depending on the polymer classification. The polymer classification divides TFCC lesions into traumatic and degenerative origins and into location and kind of lesion. Due to the poor accuracy of this test, the diagnostic value is rather weak. Interestingly, MRI imaging did not

perform better and reached a comparable high level of sensitivity but poor specificity in the study. For the ulnar fovea sign, the examiner palpates the soft spot between the ulnar styloid, the flexor carpi ulnaris tendon, and the volar

surface of the ulnar head and the radial head. Reproducible pain at this spot as compared with the contralateral side resembles a positive ulnar fovea sign. Alright, this was our video on the fovea sign. Another test for the TFCC is the ulnar

grinding test, that you can watch by clicking in the top right corner. As always, thanks a lot for watching. Don't forget to subscribe to our channel for more physiotherapy content and leave a like if you enjoyed this video. I'll see you in
