Hypertension as a complication of circular external fixators.

Hypertension is not a recognized complication of circular external fixation. The aim of this study was to determine the incidence of hypertension following this procedure. A retrospective review of 57 patients was carried out between January 2006 and May 2010. At least three blood pressure readings were used to define hypertension. Five of the 41 qualifying patients (12.2%) developed hypertension. Three of these were found to have a sustained hypertension throughout the frame period, two requiring treatment for visual symptoms and left ventricular hypertrophy. A limb reconstruction surgeon needs to be alert to this potential complication to initiate prompt investigations and treatment.
