Distraction Arthroplasty of the Ankle: Current Concepts

Abstract

• Advanced osteoarthritis of the ankle joint can be one of the most difficult and debilitating pathologies. • Different classification systems emerged to help classify the degree of ankle OA it its proper management. • Although no single treatment is appropriate for every patient, the investigators (result) considered the use of distraction arthroplasty of the ankle a viable alternative to previously accepted treatments. • Decreased soft tissue dissection associated with the use of the external fixation device as compared to more aggressive procedures make this treatment available to a wide range of patients. • Arthrodesis of the ankle joint should be avoided in younger patients as stress placed on adjacent joints following ankle arthrodesis often leads to arthritic changes in these joints as well. • The non-destructive nature of distraction arthroplasty creates an additional option to delay arthrodesis or total ankle replacement provided the patients are proper candidates for the procedure and understand the possible need for a more aggressive procedure later on in life.
