Sesamoiditis

Causes and Risk Factors for Sesamoiditis

Every time the big toe is used to push the foot forward, the sesamoid bones are put under extreme pressure. Therefore, anyone who walks can develop sesamoiditis. People who participate in activities that involve repetitive stress to the ball of the foot such as sprinting or dancing are at increased risk.

Individuals with high arches, flat feet and those who run on the ball of their foot are also more likely to develop this condition.

Symptoms of Sesamoiditis

Symptoms of sesamoiditis tend to develop gradually, starting as a mild ache under the big toe joint. If left untreated, symptoms may worsen to include:

• Intense, throbbing pain in the ball of the foot.
• Difficulty walking or putting any weight on the big toe.
• Swelling or redness around the big toe joint.
• Pain when trying to flex the big toe upwards.

If any of these symptoms are present, it’s important to be evaluated by an orthopedic specialist as soon as possible. Early detection and treatment can help prevent the condition from worsening and potentially causing permanent damage.

Diagnosis & Treatment of Sesamoiditis

In addition to taking a complete medical and lifestyle history, your doctor will perform a physical exam of the foot and may order an X-ray to confirm a diagnosis of sesamoiditis. Because the edges of the sesamoid bones are usually smooth, an X-ray can reveal jagged edges that indicate sesamoid fracture.

Initial treatments for sesamoiditis are typically conservative and designed to manage pain and other symptoms. Treatments may include:

• Rest, ice and elevation
• Nonsteroidal anti-inflammatory medications (NSAIDs) like ibuprofen
• Padding, strapping or custom orthotics to take pressure off the sesamoid bones
• Cortisone injections
• Use of a medical boot or walking cast

If conservative treatment isn’t effective, your orthopedic specialist may recommend surgery to remove the damaged sesamoid bone.
