Sinus Tarsi Syndrome

Sinus Tarsi Syndrome is a painful condition where the fluid and tissue inside the sinus tarsi become inflamed. Usually caused by overuse and often associated with ankle sprains.

The sinus tarsi is a small bony canal which runs into the ankle under the talus ankle bone.

 Causes:

👣 Common in runners

👣 Poor biomechanics

👣 Previous ankle sprain

 Symptoms:

👣 Pain can be difficult to locate, but is somewhere just in front of the bony bit on the outside of the ankle (lateral malleoli)

👣 Pain may occur when running on curves

👣 Inverting the ankle (turning ankle inwards)

 Treatment:

👣 Follow the POLICE protocol:

 Protection- Rest for the first few days following injury, however, you should then begin gentle motions to maintain movement and avoid a decreased muscle strength and flexibility. You may require assistive devices at this time, for example crutches.

Optimal Loading- Whilst protecting the effected area, gentle movement should be started to help promote optimal healing of the injury and prevent delay in returning to normal activities.

Ice- Apply ice to help manage swelling. Ice can also help decrease some acute pain.

Compression- Compression bandaging will help reduce swelling as a result of the inflammatory process.

Elevation- Elevating the foot above heart level will help reduce swelling by allowing fluid to drain from the area.

👣 Non-Steroidal anti-inflammatory drugs

👣 Mobilisation of the ankle joint

👣 Orthotic prescription

👣 Strengthening exercises
