Digital illustration of sinus tarsi Syndrome generated by EVE.
Sinus tarsi syndrome (STS) is when the sinus tarsi (tunnel/bony canal at the front of the foot) is inflamed. This is due to overuse or over-pronating (having flat feet), and it is commonly mistaken for an ankle sprain.
The sinus tarsi space has many connective tissues, nerves and blood vessels within it that help to keep the ankle and foot steady. Injury to these tissues can lead to instability of the subtalar joint in the foot which helps to invert and evert it (turning the base of the foot out and in). If this joint is unstable then it can change the way you walk and lead to increased stress, irritation and inflammation in that area.
Athletes that do a-lot of running, sudden movements or abrupt stops have an increased risk of developing STS. Sitting with your feet tucked underneath you is another common way to develop STS. If an athlete has a reoccurring ankle sprain it may actually be STS.
