17-year-old male with a right scaphoid fracture. Evaluate for avascular necrosis. Suboptimal evaluation secondary to extensive patient motion artifact.LIGAMENTS: There is widening of the scapholunate interval. The lunotriquetral ligament appears intact within the limitations of this arthrogram study. There is intermediate signal abnormality within and thinning of the scapholunate ligament which may represent partial thickness tearing of the membranous portion and dorsal component of the scapholunate ligament, within the limitations of this non-arthrogram study.TRIANGULAR FIBROCARTILAGE COMPLEX: There is a subcentimeter focus of fluid signal intensity along the ulnar aspect of the ulnar styloid insertion of the triangular fibrocartilage complex which may represent ganglion formation. The imaged components of the triangular fibrocartilage complex appear intact, within the limitations of this nonarthrogram study.TENDONS: The flexor and extensor tendons appear intact. BONES: There is linear decreased signal abnormality traversing the waist of the scaphoid consistent with the patient's known history of a scaphoid fracture. There is approximately 2 mm of radial displacement of the distal fracture fragment. There is increased signal abnormality on fluid sensitive sequences within both fracture fragments. There is no diffuse decreased T1 signal abnormality within the proximal fracture fragment to definitively suggest avascular necrosis. There is no fracture fragment collapse identified. Intravenous contrast was not administered on this examination. There is increased signal abnormality within the trapezium and capitate which may represent bone contusions.ADDITIONAL
1. Suboptimal evaluation demonstrating a fracture of the scaphoid without findings to suggest avascular necrosis. 2. Widening of the scapholunate interval. The scapholunate ligament appears thinned, indicating at least partial thickness tearing in the membranous portion of the ligament. 3. Other findings as described above.
