68-year-old female presents with right wrist pain after a fall, evaluate for tear of the triangular fibrocartilage complex. Some sequences are limited by patient motion artifact.TRIANGULAR FIBROCARTILAGE COMPLEX: Gadolinium extends from the radiocarpal joint into the distal radioulnar joint through a large tear of the articular disc of the triangular fibrocartilage complex near its radial attachment. There is also undulation and increased signal intensity within the volar radioulnar ligament which is suspicious for a tear of this structure. LIGAMENTS: Contrast is also noted within the mid-carpal joint, perhaps from a tear of the membranous portion of the lunotriquetral ligament, however, the actual defect is not well defined. No definite tear of the scapholunate ligament is identified.TENDONS: There is a small amount of fluid along the extensor pollicis longus tendon as it courses over the second compartment tendons, of questionable significance. The remaining tendons appear intact. BONES: There is a fracture through the hook of the hamate best seen on image 10 of series 9 with edema in the adjacent medullary bone. Bone marrow signal intensity is otherwise normal.ADDITIONAL
Tear of the triangular fibrocartilage complex and fracture of the hook of the hamate. These findings were relayed to the patient following the procedure. Other findings as described above.
