Arthritis Mutilans,
What Do You See? No. 12

The collapse pattern of this patient’s thumb demonstrates Arthritis Mutilans, an uncommon arthropathy which causes the bone to vanish as it is absorbed. As the digit shortens excess skin becomes evident and severe instability of the digit/s results. This photo shows severe involvement of the thumb, but relatively little involvement of the fingers.
