What Are Sesamoid Bones and Sesamoiditis?
When I show patients their foot X-rays, one of the most common questions I hear is, “What are those round white spots?” These small, round bones are called sesamoids, and they play a crucial role in the foot’s mechanics. Found under the big toe joint, sesamoids help the joint move smoothly and painlessly during walking and other activities.
However, these tiny bones can sometimes become inflamed or injured, resulting in pain and discomfort—a condition known as sesamoiditis.
What is Sesamoiditis?
Sesamoiditis is an overuse injury caused by repetitive trauma to the sesamoid bones. This condition typically leads to localized pain under the ball of the foot, often near the tibial sesamoid, which is the most commonly affected bone.
Dancers, particularly ballet dancers, are prone to sesamoiditis because of the significant time they spend putting pressure on the balls of their feet.
Treatment Options
- Shoe Modifications: The first line of treatment for sesamoiditis is modifying shoe gear with a dancer’s pad. This specialized pad has a cutout near the ball of the foot to redistribute weight away from the inflamed area. By shifting pressure laterally, the pad reduces stress on the sesamoids and alleviates pain.
- Anti-Inflammatory Measures: Prescription NSAIDs (non-steroidal anti-inflammatory drugs) and ice application are often recommended to reduce inflammation and manage pain.
- Steroid Injections: In more severe cases, a steroid injection may be administered to target inflammation directly.
- Custom Orthotics: For persistent cases, custom orthotics with a built-in dancer’s pad cutout can provide long-term relief. These devices are tailored to support the foot’s biomechanics and prevent further stress on the sesamoid bones.
