Scapholunate pain. Contrast is noted within the midcarpal joint. No contrast is seen extending into the radiocarpal joint to indicate either a scapholunate or lunotriquetral ligament tear. There is a 1cm collection of fluid signal intensity volar to the radial styloid immediately superficial to the attachments of the long radiolunate and radioscaphocapitate ligaments that I suspect represent a ganglion, but could conceivably reflect degeneration or partial thickness tearing of the underlying extrinsic ligaments.There is heterogeneity of signal of the medial fibers of the articular disk of the triangular fibrocartilage complex at and near its ulnar styloid attachment suggestive of degenerative tearing. Mild edema type signal within the adjacent ulnar styloid is likely reactive in etiology. Furthermore, there is a small linear focus of increased signal intensity partially traversing the articular disk near its radial attachment that I suspect represents a tear.There is fluid within the sheaths of the extensor digitorum tendons that could conceivably represent mild tenosynovitis but but may simply be due to injection of lidocaine during the arthrogram portion of the procedure. The tendons are otherwise unremarkable.
1.No evidence of scapholunate ligament tear.2.Findings suggestive of tearing of the articular disk of the triangular fibrocartilage.3.Small collection of fluid signal intensity volar to the radial styloid may represent a ganglion.
