Sesamoiditis

Sesamoiditis is a common ailment of the plantar forefoot which causes pain in the ball of the foot specifically under the big toe joint. The sesamoid bones are very small bones which are located under the big toe joint within the tendons that run to the big toe. They work to increase the leverage of the tendons that control the big toe. Due to their location and function they are subjected to massive pressure and forces every time the big toe is used to push the foot forward. Activities such as running which involves repetitive excessive loading of the ball of the foot can lead to this condition. Runners with boney, higher arched feet, runners with flat feet or those who tend to run on the ball of their foot also tend to be more prone to sesamoiditis.

Symptoms of Sesamoiditis

Sesamoiditis typically presents as a mild ache increasing gradually where it can become an intense throbbing in the ball of the foot. .

Treatments for Sesamoiditis

These will vary between patients and will typically involve a period of rest from any activities likely to aggravate the problem.
● Immobilization strapping, ice and oral anti inflammatory drugs may also be utilized to settle inflammation and pain and aid in the healing process.
● Wearing a soft full length functional orthotic insole is commonly used to offload the sesamoids and deflect pressure away from the pain area.
Orthotics are essential in treating an underlying causative foot condition such as flat feet, high arched feet, bunions or those with reduced plantar fatty padding.
