Bilateral 5th MTP joint destructions in rheumatoid arthritis


Despite the increased sensitivity of other modalities (particularly MRI), radiography remains the mainstay of imaging in the diagnosis and follow-up of RA. It's possible to see in this case:

  • joint space narrowing: symmetrical or concentric
  • marginal erosions: due to erosion by pannus of the bony “bare areas

Similar to the hands, there is a predilection for the DIP and MTP joints.
