Article Figures & Data

Figures

  • FIGURE 1.
    FIGURE 1.

    Typical presentation of complex regional pain syndrome. (A and B) Blood flow and blood pool images demonstrate increased activity diffusely in right hand and more focally in right wrist (arrow). (C) Delayed images demonstrate periarticular accentuation in multiple interphalangeal and metacarpophalangeal joints of involved hand (black arrows). Right wrist uptake (blue arrow) is consistent with recent fracture.

  • FIGURE 2.
    FIGURE 2.

    (A) Radiograph of wrist demonstrating fracture of distal radius with Colles angulation. (B) Radiograph of hand demonstrating no abnormality (B).

  • FIGURE 3.
    FIGURE 3.

    Example of atypical presentation of complex regional pain syndrome. A 45-y-old woman presented with pain in right lower extremity for over 1 mo. Bone scanning demonstrated diminished radiotracer uptake (arrows) in right foot and distal leg in all 3 phases—blood flow (A), blood pool (B), and delayed (C)—as well as on whole-body images (D).
