Ulnar wrist pain LIGAMENTS: We see no contrast traversing the scapholunate or lunotriquetral ligaments to suggest the presence of a tear. There is also no contrast within the midcarpal joint.TRIANGULAR FIBROCARTILAGE COMPLEX: There is a poorly defined near-linear focus of increased signal intensity within the articular disc of the triangular fibrocartilage that we suspect corresponds to the contrast-filled perforation seen on the conventional arthrogram images. Only a scant amount of gadolinium is seen within the distal radioulnar joint and it is possible that this perforation is of no clinical significance.TENDONS: The extensor carpi ulnaris tendon is situated within the ulnar groove when imaged in the pronated position; however there is medial subluxation of the tendon from the groove when in supination. Small linear intrasubstance foci of increased signal intensity within the tendon that extend to the surface could represent small partial-thickness tears, but we see no fluid within the tendon sheath or edema and the surrounding soft tissues to suggest an acute injury; thus the clinical significance of these findings is uncertain.BONES: No significant abnormality noted.ADDITIONAL
1. Small, barely perceptible perforation of the articular disc of the triangular fibrocartilage which is of uncertain clinical significance.2. Subluxation of the extensor carpi ulnaris tendon from the ulnar groove on supination. Although there are perhaps small partial-thickness tears of the tendon, we see no fluid in the tendon sheath or surrounding soft tissue edema; thus the clinical significance of these findings is uncertain.
