Angioplasty balloon catheters used for distraction of the ankle joint.

Abstract

Arthroscopy of the ankle joint is now routinely performed in diagnostic and therapeutic interventions but is still a demanding and difficult operative procedure in this very small and tight joint. Arthroscopy can be facilitated by a sufficient distraction that gives a better overview of the joint space. However, it is still a matter of debate how to obtain the adequate distraction. Distention by manual strength as well as by the help of a technical device have been proposed. We report our experience with distraction of the ankle joint by the help of one or two intraarticularily located and secondarily insufflated angioplasty balloon catheters that are routinely used in interventional radiology. These special catheters allow a careful and controlled distention of the joint with a fixed space of distraction and, according to our limited experience, without any morbidity.
