Evaluate right wrist fractureIMAGE ACQUISITIONS: CT of the right wrist was performed without contrast using the ultra high resolution protocol. There is a transverse fracture of the ulnar styloid. The bones appear in near anatomic alignment. There is a comminuted fracture of the radial aspect of the trapezium with it least two separate fragments adjacent to the main trapezium bone. There is mild displacement of the fracture fragments. There is a 2-mm ossific fragments in the just posterior and on the radial side of the lunate which which is likely a fragment from the trapezial fracture. Another 2-mm ossific fragment located just superior to the trapezium in between the trapezium and first metacarpal also is likely a fracture fragement given its proximity to the fracture trapezium comment this could be an acute fracture fragment.There is a 4-mm well corticated ossific density anterior to the lunate which does not appear to be an acute fracture fragment.There is slight widening of the scapholunate interval however this does appear stable. The patient had a previous MRI which shows a tear the scapholunate ligament which appear chronic.Small to moderate sized joint effusion is present.The remainder of the carpal bones, distal radius, and proximal metacarpal bones which are visualized on this study appear intact. No other fractures are identified.Cast material is seen surrounding the wrist.
Fractures of the ulnar styloid and trapezium as described above.
