Sesamoiditis, Sesamoid Fractures & AVN
Causes, symptoms, and treatment for sesamoiditis, sesamoid fractures, and AVN, with care at 15 clinics across Middle Tennessee.
Understanding sesamoiditis, sesamoid fractures, and AVN and your options.
The sesamoids are two tiny bones under the big toe joint that act like pulleys for a tendon. Sesamoiditis means these bones and the tendon around them are irritated. A sesamoid can also crack, and in rare cases the bone can lose blood supply, which is called avascular necrosis (AVN).
These problems are common in runners, dancers, and people who spend time on the balls of their feet. Early care can protect the bones and help you avoid long-lasting pain.

Diagnosis and care
How we treat sesamoiditis, sesamoid fractures, and AVN.
Step 1 · Diagnosis
We press under the big toe joint and test how the toe moves against resistance. X-rays show the sesamoids and whether one is cracked. MRI or a CT referral may be used to look for bone stress, a loss of blood flow, or an injury not seen on X-ray.
Step 2 · Treatment
Taking weight off the sesamoids is the key. Cushioned shoes, a padded insert that gives the area a dip, and stiff-soled footwear help. A walking boot or taping may be needed for a period of time. Anti-inflammatory care, physical therapy, and an injection can also be part of the plan.
Surgery is not common but may be advised for a fracture that does not heal or for AVN. The procedure may remove all or part of the sesamoid.
Recovery
What to expect over time.
Simple irritation often improves in several weeks to a few months. Fractures and blood flow problems can take longer, sometimes several months.
When to book
Do not wait it out.
See a podiatrist if pain under the big toe lasts more than a week or two or came on after a fall or jump. Come sooner if you cannot bear weight or the joint swells.

FAQ
Your questions answered.
How can I tell if it is sesamoiditis or a fracture?
The pain can feel alike, so an exam and X-ray are needed. MRI may be added when the answer is unclear.
What does AVN mean for the sesamoid?
It means part of the bone has lost blood flow and may weaken. It is uncommon and is watched closely with imaging.
