Dystonia after a bone fracture of the arm in a patient with a history of striato-pallidal ischemic stroke: a case report.

We report on a female with segmental dystonia of the upper limb after an anatomically related ischemic stroke. Dystonia developed almost 3 years after the onset of the stroke and immediately following the removal of the cast because of a bone fracture in the same limb. We discuss the case considering issues such as: delay-onset, lesion topography and pathophysiology, peripheral input and their possible contribution to the development of secondary dystonia.
