Sinus Tarsi

The sinus tarsi is the indention on the lateral aspect of the foot, anterior to the lateral malleoli, that is the collecting place for the edema after an injury to the ankle. 


To help rid swelling from this area or even prevent swelling from this area after an injury a horse shaped pad can be cut out and place under the lateral malleoli with a compression wrap over it.  This will help push all swelling up and out of the leg to help relieve pain and retain original range of motion.  

If the swelling is not controlled there could be issues with normal healing time, range of motion, and if there is a fracture it will make it harder to read an x-ray.
