The Function of the Sesamoid Bones in the Feet

Sesamoid bones are tiny bones that are found near joints within muscles or tendons. They act like pulleys to reduce stress on these muscle-tendon areas. Unlike regular bones that connect at joints, sesamoid bones connect to muscles using tendons. The word sesamoid comes from the Arabic word sesamum, which means sesame, because they are small like sesame seeds. These bones are often in the foot, hand, and wrist. Sesamoid bones usually develop due to extra strain on muscles and tendons. Their main job is to ease tension in muscles and tendons, making them better at carrying weight and more resilient by distributing it evenly. This helps protect these various parts of the body from getting too strained or injured. Even though they are small, sesamoid bones are vital in how our bodies work. If you have pain in your feet corresponding to the location of these bones, it is suggested that you schedule an appointment with a podiatrist for a proper diagnosis and treatment

Sesamoiditis is an unpleasant foot condition characterized by pain in the balls of the feet. If you think you’re struggling with sesamoiditis, contact one of our podiatrists of Bruening Foot & Ankle. Our doctors will treat your condition thoroughly and effectively.


Sesamoiditis is a condition of the foot that affects the ball of the foot. It is more common in younger people than it is in older people. It can also occur with people who have begun a new exercise program, since their bodies are adjusting to the new physical regimen. Pain may also be caused by the inflammation of tendons surrounding the bones. It is important to seek treatment in its early stages because if you ignore the pain, this condition can lead to more serious problems such as severe irritation and bone fractures.

Causes of Sesamoiditis

  • Sudden increase in activity
  • Increase in physically strenuous movement without a proper warm up or build up
  • Foot structure: those who have smaller, bonier feet or those with a high arch may be more susceptible

Treatment for sesamoiditis is non-invasive and simple. Doctors may recommend a strict rest period where the patient forgoes most physical activity. This will help give the patient time to heal their feet through limited activity. For serious cases, it is best to speak with your doctor to determine a treatment option that will help your specific needs.
