Sinus Tarsi Syndrome

The sinus tarsi is an opening on the outside of the foot between the ankle and heel bones. Sinus tarsi syndrome refers to localized pain, instability, and difficulty with weight-bearing activities. This condition commonly occurs after an inverted ankle sprain, (the foot rolls out), or it can be caused by a pinching of soft tissues in the area from a pronated (rolled inward) foot. Patients have trouble navigating uneven surfaces and feel pain when the area is touched. The ankle and foot joints often feel loose and unstable. Because treatment for sinus tarsi syndrome differs from that of other foot and ankle problems, an accurate diagnosis is important. Treatment may include anti-inflammatory medication, injections, supportive shoes, immobilization of the area, and/or orthotics.

Pain may be one of the first signs of a foot problem, but it doesn’t always reveal the cause of the condition. The best way to determine the exact cause, location, and seriousness of foot pain is to have a podiatrist evaluation that includes medical history, examination, and tests. And at SHENANDOAH PODIATRY, complete instructions for follow-up care and prevention are also an integral part of any treatment plan we formulate.
