Reflex Sympathetic Dystrophy

reflex sympathetic dystrophy

This patient had a long-standing immobilization due to a fracture of the right humerus. The appearances in the right hand are classical for reflex sympathetic dystrophy, or Sudeck’s atrophy, and include:

1. Pronounced demineralization of the bones, particularly in the periarticular region.
2. No joint involvement.
3. Associated soft tissue atrophy.

This condition has been recently renamed the “complex regional pain syndrome”.
