Case 46 - 35-year-old female presents with right wrist triangular fibrocartilage complex (TFCC) pain

<div>HISTORY:&#160;This 35-year-old female presents with right wrist triangular fibrocartilage complex (TFCC) pain, forearm discomfort, and wrist sprain.(QUIZ ANSWER) PRIMARY FINDING:&#160;Palmer 1 C abnormality.Using the&#160;diagnostic web viewer, we have provided images that assist in telling our clinical story. Areas of significance are indicated below.FINDINGS:&#160;Moderate soft tissue edema within the dorsal, peripheral aspect of the triangular fibrocartilage complex consistent with dorsal ulnocarpal ligament injury.&#160;Styloid, foveal and radial articular disc attachments are intact.&#160;Palmar radioulnar ligament intact. Lunotriquetral ligament intact.&#160;Extensor carpi ulnaris intact.&#160;Distal radioulnar congruence normal.Scapholunate ligament and scapholunate interval normal.&#160;Lunate morphology and position normal.&#160;No active carpal erosions or osteoedema.&#160;Ganglion cyst arising from the scaphotrapeziotrapezoid articulation projecting in a palmar direction lying deep to the flexor carpi radialis and flexor pollicis longus tendons and measuring 4mm in diameter short axis and 1.1cm in length.Carpal tunnel and Guyon's canal normal.&#160;Flexor tendons normal.&#160;Thenar and hypothenar muscles normal.CONCLUSION:1. Triangular fibrocartilage complex injury consisting of dorsal ulnocarpal ligament tear with intact articular disc (Palmer 1C) and surrounding soft tissue swelling.&#160;Distal radioulnar joint is congruent.2. Ganglion cyst arising from the palmar aspect of the scaphotrapeziotrapezoid articulation lying deep to the flexor pollicis longus and flexor carpi radialis tendons.</div>
