Ankle Distraction - Introduction
Ankle distraction arthroplasty, also known as arthrodiastasis, is an alternative to a total ankle replacement or ankle fusion for younger patients with end stage ankle arthritis.
Ankle Distraction - Procedure
In this procedure, a circular external fixation device is applied to the lower leg and the ankle joint is slightly pulled apart (distracted). Patients are able to walk immediately after application and the external fixator is left in place for three months.
The hydrostatic pressure changes created in the ankle joint from distraction and loading with weightbearing have been reported to stimulate cartilage regeneration. After three months the external fixation device is removed.
Who Should Consider Ankle Distraction?
Ankle distraction athroplasty is a stronger consideration for patients in their twenties and thirties, because they are able to generate better-quality cartilage in the ankle joint.
What to Do Next?
Ankle distraction arthroplasy may help delay a total ankle replacement or ankle fusion, both of which have risks in a younger patient with end stage ankle arthritis.
