Sesamoiditis - A Swelling Of Bones In The Foot

What Is Sesamoiditis?

A sesamoid bone is a bone that is between two tendons such as the knee cap (Patella) or the two bones at the base of the big toe on its under surface. These bones give the muscle a mechanical advantage to move the joint. Sesamoiditis is an inflammation of this bone. This predominantly occurs in the flexor hallux brevis muscles of the foot.

What Are The Symptoms Of Sesamoiditis?

·      Pain under the big toe
·      Pain when bending the big toe
·      Swelling around the big toe
·      Redness or bruising around the toe
·      Difficulty when walking or weight bearing on the front of the foot.

How Do Orthotic Insoles Help?

Sesamoiditis occurs because the sesamoid bones are experiencing too much pressure due to a rigid high foot or an overpronator flat foot. Orthotic insoles help by increasing the surface area of the foot in contact with the ground offsetting the pressure placed on the sesamoid bones. At the front of the orthotic insoles we can also place a small cut out that will directly take the pressure away from the sesamoid bones decreasing the pressure that they experience.

What Orthotic Insoles Are Best For Sesamoiditis?

Orthotic insoles that help relieve the pressure on the sesamoid bones can include both over-the-counter and custom fabricated orthotic insoles . We recommend for most people custom made orthotic insoles due to the fact that the foot posture and the pressure on the sesamoid bones are both contributing causes to the sesamoiditis. This means that usually there are multiple areas of the foot that needs to be corrected which can be difficult with an over-the-counter orthotic insoles.
