Sinus Tarsi Syndrome is a condition characterized by pain and tenderness in the sinus tarsi, a small bony cavity located on the outside of the ankle between the talus bone and the calcaneus bone. It is typically caused by repetitive stress, trauma, or overuse of the foot and ankle.
Symptoms of Sinus Tarsi Syndrome may include pain and tenderness in the sinus tarsi region, swelling and stiffness of the ankle joint, and difficulty walking or bearing weight on the affected foot. Pain may be worse with activity and improve with rest.
Risk factors for developing Sinus Tarsi Syndrome include chronic ankle instability, overuse or repetitive stress on the foot and ankle, and certain anatomical abnormalities that affect the alignment of the foot and ankle.
Treatment for Sinus Tarsi Syndrome may include rest, ice, compression, and elevation of the affected foot, as well as physical therapy exercises to strengthen the muscles and improve flexibility. Pain management medications and anti-inflammatory medications may also be prescribed to help alleviate symptoms. In some cases, immobilization with a cast or brace may be necessary to allow for proper healing.
