Male 60 years old Reason: peri-lunate dislocation? Chronic vs acute? Sagittal sequence is degraded by motion. LIGAMENTS: The scapholunate and lunotriquetral ligament are disrupted.TRIANGULAR FIBROCARTILAGE COMPLEX: The triangular fibrocartilage complex is grossly intact.TENDONS: T2 hyperintense fluid signal surrounding the majority of the flexor tendons indicating a tenosynovitis, possibly traumatic in etiology.BONES: The lunate is rotated and partially subluxed anteriorly in relation to the capitate which is perched posteriorly upon it. Findings consistent with a perilunate dislocation. Cysts are present within the scaphoid, capitate, trapezium, and base of the fifth.ADDITIONAL
1.Perilunate dislocation and associated disruption of the scapholunate and lunotriquetral ligaments.2.Tenosynovitis of the flexor tendons, possibly traumatic in etiology.
