Is there a hereditary reason for sesamoiditis?

No: Typically not. Some people are born with bipartite sesamoids but are usually not symptomatic. Sometimes the division in the sesamoid is a weak point that can be irritated with activity.

Dr Niazi agreed

Yes and no: Sesamoiditis refers to inflammation and pain in the sesamoid bones- two small bone within the flexor tendon underneath the first metatarsal bone of the foot. Generally an acute condition aggravated by increased pressure by either excessive running or walking. It is not genetically inherited, but the structure of your foot is and it may be prone to the development of the condition.

Structure: Sesamoiditis without an injury is usually seen in a high arched foot where there is more pressure on the ball of the foot. Another common deformity that can cause this condition is a bunion deformity because the sesamoids are subluxed from their normal groove under the first metatarsal head in a progressed bunion deformity.

Dr Ettinger and another doctor agreed
