Diagnoses and symptoms

Ankylosis or stiffening of the lower ankle joint (arthrodesis)

A procedure to stiffen the ankle joint can be performed in cases where it has undergone severe changes, for example, due to arthrosis. After this procedure called arthrodesis, an orthosis protects the ankle joint and gradually increases the foot’s capacity to bear weight.

Indication

Indication

An arthrodesis is performed in certain cases where the individual has severe arthrosis, considerable and chronic joint instability or severe malpositions.

Causes

Causes

Common causes for an arthrodesis are severe and complex joint changes or injuries that restrict the individual’s everyday life to an extreme extent.

Diagnosis

Diagnosis

The doctor makes the diagnosis based on the individual’s medical history (anamnesis) and an assessment, often complemented by imaging procedures.

Therapy

Therapy

The therapy is always surgical, with an incision made in the skin on the outside of the foot in the lower ankle joint. When the joint is exposed, the articular surfaces on the ankle bone and calcaneus (heel bone) are surgically removed. Finally, screw connections are used to bring the joint into a functional position. The leg is able to bear full weight after 10 to 12 weeks of rehabilitation at the earliest. An orthosis supports the ankle joint during this time. It facilitates physiological movements in most cases, particularly the rollover movement of the foot.
