Sesamoiditis is a condition in which there is pain and inflammation surrounding the small bones under the big toe joint called the sesamoids. Most people have two sesamiods underneath the first metatarsal head called the tibial and fibular sesamoids. They are marble sized and shaped bones that sit on either side of the flexor tendons to the big toe. Because of their location these bones tend to take up a lot of force with activity since they are right at a weight bearing surface. If they become inflamed it is important to seek treatment as this is a condition in which early treatment can decrease the length of the condition.
Treatment for sesamoiditis consists of examination of the area and radiographs to rule out fracture or avascular necrosis (death of the bone), offloading with a surgical shoe or boot and R.I.C.E therapy. Sometimes special imaging may need to be ordered if the diagnosis is not straight forward.
