What is Sesamoiditis?

The sesamoids are two bones underneath the great toe. They lie within the tendon of flexor hallucis brevis. The main function of the sesamoids is they act in a similar way to the knee caps,  increasing the leverage of the muscles that flex the toe.

Pathology of the sesamoids is referred to as sesamoiditis and typically occurs from increased pressure and demand on the sesamoids.

What Causes of Sesamoiditis

Sesamoiditis is typically a result of chronic overloading of the sesamoid this can be as a result of:

  • Abnormally force applied to the sesamoid
  • Poor footwear
  • Altered biomechanics such as having a high or a flat arched foot

Sesamoid pain may also occur where there is an abnormality with one of the sesamoid bones such as a:

  • Bipartite sesamoid
  • Old fractured sesamoid

Diagnosis of Sesamoiditis

Diagnosis is usually based or symptoms and a complete assessment of your foot and ankle.

At the Ankle, Foot and Orthotic Centre we are able to provide additional information about the presence of sesamoid damage with ultrasound imaging.
