Sinus Tarsi Pain Explanation


The sinus tarsi is a component of the subtalar joint

The subtalar joint is the joint responsible for pronating and supinating the foot

When the foot is neutral the sinus tarsi is aligned and there is no compression of the tissues.

When the foot is flat or pronated the sinus tarsi is compressed and can cause pain.

Certain factors are though to increase the risk for sinus tarsi pain including

  • Non- Supportive footwear
  • Flat arched feet
  • Trauma
  • Hypermobile foot posture
  • Being overweight
  • Hormone problems (Reduced Thyroid function, Menopause)
  • Connective tissue disorders (Rheumatoid arthritis)
