[Scaphoid fissure in algodystrophy: diagnostic value of MRI].

Stress fractures are exceptional in patients with reflex sympathetic dystrophy syndrome, even when bone loss is severe. We report a case of stress fracture of the navicular bone documented by magnetic resonance imaging. Recurrence of localized pain in patients with reflex sympathetic dystrophy syndrome suggests either a relapse of the syndrome or a bony fissure. Magnetic resonance imaging can provide early differentiation of these two conditions.
