What is it
Sesamoiditis is inflammation of the sesamoid bones. These two tiny bones sit side by side and within the tendon that attaches to the big toe. Sesamoiditis is a very cause of pain beneath the big toe joint.
Cause
The sesamoid bones can become inflamed due to being repetitively compressed. Compression of these bones is usually due to over pronation. If the foot rolls in too much and doesn’t quite roll back out far enough the big toe joint can jam up resulting in the sesamoids being compressed and then inflamed causing pain.
How Orthotics will help
Orthotics can help treat and prevent sesamoiditis by controlling how far the foot is allowed to roll in. Thereby keeping the foot in a more functional position and preventing the big toe joint from jamming up.
