Why is the Norgaard (ball-catcher view) used if SLE arthropathy is suspected?
In the standard PA view, the fingers are pushed into standard position. In the Norgaard view, the fingers are not positioned and potential subluxations are better seen.
Radiographs of the hands, including Norgaard (ball-catcher's) views. There are multiple typical findings in SLE arthropathy, including
- marked contractures and subluxations in a bilateral symmetric pattern
- swan neck deformities, particularly in the right hand
- hooked heads of the second and third metacarpals
- juxta-articular osteopenia
- no erosions
- no soft tissue calcifications
