What is the pathophysiology of sinus tarsi syndrome?
[1] [2] [4] This pathology is mostly a result of synovitis and infiltration of fibrotic tissue into the sinus tarsi space due to an instability of the subtalar joint, caused by ligamentous injuries. [2] The sinus tarsi syndrome can also occur as a compression injury, for example to people who have flat or pronated feet.

Cause can be due to an inversion (rolling out) ankle sprain (70-80% of the time) or can be due to a “pinching” or impingement of the soft tissues in the sinus tarsi due to a very pronated (rolling in) foot (20-30% of the time). Clinical Presentation:
Is surgery necessary for sinus tarsi syndrome?
Surgery usually is not necessary in most patients who develop sinus tarsi syndrome. Non-surgical treatment can be very successful in relieving pain and swelling. Prior to considering surgery, it is important to see a foot and ankle orthopaedic surgeon to identify the cause of the sinus tarsi syndrome and the best treatment for that problem.

What causes tarsal syndrome?
Tarsal tunnel syndrome is caused by anything that produces compression on the posterior tibial nerve, such as: A person with flat feet is at risk for developing tarsal tunnel syndrome, because the outward tilting of the heel that occurs with fallen arches can produce strain and compression on the nerve.
