Sinus Tarsi Syndrome

Sinus tarsi syndrome occurs when there is too much movement in the joint or a lot of compression occurring.

This region is typically just a 'space', however, if you have had an injury that results in increased instability in the ankle; then you might develop synovitis or have scar tissue form within the joint.

Synovitis is a diagnosis for synovium (lubricating stuff) that has become inflamed within the ankle. This, combined with scar tissue formed within the joint as a result of the increased movement / injuries willthen become inflamed.

The inflammation then gets gradually worse as time goes on as the instability remains and with inflammation comes pain.

Diagnosis is the first thing that needs to happen. Once you have a diagnosis, the treatment can be targeted to your needs: managing the instability or managing the compression occurring.
