Disproportionate pain, swelling, vasomotor instability, and trophic skin changes raise the suspicion of post-traumatic reflex sympathetic dystrophy (complex regional pain syndrome, type 1). Findings relate to hyperemia (increased blood flow and blood pool on bone scan), and peri-articular osteopenia with preservation of joint space.
