Quick Answer: What is sesamoiditis?
Sesamoiditis is inflammation of the two small sesamoid bones within the tendons beneath the big toe joint. It usually develops from repetitive stress or sudden injury, causing pain, swelling and difficulty walking. Management focuses on resting the foot, supportive footwear and anti-inflammatory treatments, and early care helps ensure full recovery and prevent stress fractures. [1]
What the research says
The big-toe sesamoids are a recognized high-risk site for stress fractures. A clinical review lists the great toe sesamoids among sites with high tensile load and low blood flow, where stress fractures heal slowly and usually need non-weight-bearing immobilization and a careful, gradual return to activity (McInnis & Ramey, PM R, 2016). [2]
Surgery gives lasting relief in the rare cases that fail conservative care. In 36 patients followed for a median of 60 months after fibular sesamoidectomy, median pain scores fell by 5 points (from 6 to 1 on a 10-point scale), 88% said they would have the surgery again, and 70% were "very satisfied" (Ford et al., Foot Ankle Int, 2019). [3]
Toe function is usually preserved after sesamoid removal. In 12 patients (14 feet) followed for an average of 111.5 months after lateral sesamoidectomy, the mean AOFAS foot score was 92.3 out of 100, all 12 rated their outcome as excellent, and big-toe joint motion was preserved (Mehtar et al., Foot, 2020). [4]
What is Sesamoiditis?
Sesamoiditis is a specific type of forefoot inflammation that affects the tiny, pea-shaped sesamoid bones and the flexor hallucis brevis tendons they are embedded in. Unlike most bones in the human body, which are connected to other bones at joints, sesamoiditis involves bones that are only connected to tendons. Located just under the big toe joint (the first metatarsophalangeal joint), these bones act like pulleys, providing a smooth surface for tendons to slide over and helping to absorb the shock of each step. [1]
When these structures are subjected to excessive or repetitive pressure, they can become irritated and inflamed. This condition is essentially a specialized form of tendonitis, where the bones themselves become part of the inflammatory process. While it is a frequent cause of general ball-of-foot pain, known as metatarsalgia, its localized nature under the big toe distinguishes it from other forefoot conditions. [1]
What are the symptoms of sesamoiditis?
The symptoms of sesamoiditis often develop gradually, beginning as a mild, dull ache that intensifies with activity. Over time, the pain may become sharp or build into a persistent throbbing sensation that makes normal movement difficult. [1]
Symptom Category | Clinical Features |
|---|---|
Pain Location | Focused directly under the big toe joint on the ball of the foot. |
Toe Mobility | Difficulty or pain when bending the big toe upward or downward. |
Weight Bearing | Increased discomfort when walking, running, or standing on the forefoot. |
Physical Signs | Localized swelling, redness, and significant tenderness to the touch. |
What causes sesamoiditis, and who is at risk?
Repetitive strain is the primary driver of sesamoiditis. Activities that require frequent weight-bearing on the forefoot put immense pressure on the sesamoid bones. Athletes who engage in high-impact sports, such as running or basketball, and ballet dancers who frequently perform movements on their toes are at the highest risk. [1]
Beyond physical activity, anatomical factors and lifestyle choices can contribute to the condition. Individuals with high arches (pes cavus) or bunions often experience changes in their gait that shift more weight onto the big toe joint (see also our guide to overpronation). Similarly, frequently wearing high-heeled shoes forces the ball of the foot to bear the majority of the body's weight, significantly increasing the likelihood of inflammation. In some cases, underlying medical conditions such as gout, osteoarthritis, or osteoporosis can weaken the area or trigger localized inflammation. [1]
How is sesamoiditis diagnosed?
To diagnose sesamoiditis, a healthcare provider typically performs a physical examination, checking for tenderness and assessing the range of motion in the big toe. A common clinical tool is the passive axial compression test, which simulates the pressure applied to the joint during walking to see if it reproduces the patient's pain. [1]
Diagnostic Tool | Purpose |
|---|---|
Physical Exam | Assessing tenderness, swelling, and toe flexibility. |
X-rays | Checking for stress fractures or changes in bone alignment. |
Bone Scan | Identifying areas of increased bone activity or inflammation. |
MRI / CT Scan | Providing detailed images of the tendons and soft tissues. |
How is sesamoiditis managed and treated?
The cornerstone of sesamoiditis treatment is rest. Removing the repetitive stress allows the inflamed tissues and bones to repair themselves. For mild cases, this may involve simply avoiding the activity that caused the pain, while more severe cases might require the use of crutches to completely offload the foot. [1]
Conservative management often includes the "RICE" method (Rest, Ice, Compression, and Elevation) to manage swelling. Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) are frequently recommended to reduce pain. For patients with chronic or severe symptoms, a healthcare provider might suggest a steroid injection to provide localized relief. Orthotic inserts or specialized shoes with a wide toe box can help redistribute weight away from the sesamoid bones as the patient returns to activity. In very rare instances where conservative measures fail, surgery to remove the affected sesamoid bone may be considered. [1]
How can sesamoiditis be prevented and managed long term?
Preventing the recurrence of sesamoiditis involves addressing the underlying factors that led to the injury. Choosing supportive footwear is one of the most effective preventive measures. Shoes should have adequate cushioning in the forefoot and a toe box that does not cramp the toes. [1]
Athletes and dancers should be mindful of their training volume and listen to early pain signals rather than pushing through discomfort. Incorporating regular periods of rest and using preventive icing after strenuous activity can help manage minor irritation before it becomes a full-blown injury. For those with anatomical foot differences, custom orthotics can provide the necessary support to balance weight distribution and protect the sesamoid bones. [1]
Conclusion
Sesamoiditis is a manageable condition that highlights the importance of foot health in maintaining an active lifestyle. By recognizing the symptoms early and committing to a period of rest and recovery, most individuals can return to their favorite activities without long-term complications.
What are the next steps for sesamoiditis?
If you are experiencing persistent pain in the ball of your foot, do not ignore it. Consult a foot specialist or healthcare provider to discuss a personalized recovery plan and ensure your feet have the support they need to stay healthy.

Frequently Asked Questions
What exactly are sesamoid bones?
Sesamoid bones are tiny bones embedded in tendons, functioning like pulleys to help the big toe move and absorb shock. [1]
Is sesamoiditis the same as a stress fracture?
No, but repetitive stress from sesamoiditis can eventually lead to a stress fracture if left untreated. [1]
How long does it take to heal?
Mild cases may improve in a few days, while severe inflammation can take several months of rest to fully resolve. [1]
Can I keep running with sesamoiditis?
It is generally recommended to stop high-impact activities until the pain and inflammation have subsided to avoid further damage. [1]
Why do high heels cause sesamoiditis?
High heels shift your body weight forward onto the ball of the foot, putting excessive pressure on the sesamoid bones. [1]
Do I need surgery for sesamoiditis?
Surgery is very rare and only considered when all conservative treatments have failed to provide relief. [1]
Can bunions cause sesamoiditis?
Yes, bunions can change how you walk, potentially shifting more weight and stress onto the sesamoid bones. [1]
What kind of shoes are best for sesamoiditis?
Supportive shoes with a wide toe box, low heels, and good forefoot cushioning are ideal. [1]
Does ice really help?
Yes, applying ice helps reduce the inflammation and swelling associated with the condition. [1]
Are steroid injections safe?
Steroid injections are generally safe when used occasionally for severe pain, though they are usually a one-time treatment. [1]
Can children get sesamoiditis?
Yes, especially active children and teenagers involved in sports or dance.
What is the passive axial compression test?
The passive axial compression test is a clinical exam where a doctor moves the big toe joint to see if it reproduces sesamoid pain. [1]
Is sesamoiditis related to gout?
While different, gout can sometimes cause inflammation in the same area, leading to similar symptoms. [1]
Do custom orthotics help?
Yes, they can redistribute pressure away from the ball of the foot and provide better support. [1]
Can sesamoiditis return?
Yes, if the repetitive stress factors (like improper shoes or overtraining) are not addressed, it can recur. [1]
