Quick Answer:
Quick Answer: Sesamoids are two small bones embedded in the flexor hallucis brevis tendons beneath the 1st metatarsal head — the tibial (medial) and fibular (lateral) sesamoids. Sesamoid pathology: sesamoiditis (inflammation/stress reaction without fracture — often overuse-related in runners and dancers), sesamoid stress fracture (incomplete or complete fracture from repetitive loading), and acute sesamoid fracture (trauma). Bipartite sesamoid (normal variant, tibial sesamoid split in two from birth) must be distinguished from acute fracture — bilateral X-ray comparison and bone scan/MRI differentiate. Treatment: acute or stress fracture — non-weight-bearing boot 6-8 weeks, OTC orthotics offloading the sesamoids. Persistent pain unresponsive to conservative care at 4-6 months: sesamoidectomy. Tibial sesamoidectomy preserves hallux alignment better than fibular sesamoidectomy — fibular sesamoid excision risks hallux varus.

The sesamoid bones — two small ovoid bones embedded in the flexor hallucis brevis tendons beneath the first metatarsal head — bear enormous load during push-off, absorbing up to 2-3 times body weight with each step in normal walking. In runners, dancers, and athletes with high forefoot loading, the sesamoids are subject to stress reactions, stress fractures, and frank fractures that produce persistent great toe pain and disability. At Balance Foot & Ankle PLLC, Dr. Tom Biernacki accurately differentiates sesamoid pathology from bipartite sesamoid variants and implements evidence-based conservative and surgical treatment.
Sesamoid Anatomy and Injury Types
The tibial sesamoid (medial, beneath the 1st metatarsal head) is larger and bears more load than the fibular sesamoid (lateral) — making it the more frequently injured. Sesamoid pathology spectrum: Sesamoiditis: Inflammation of the sesamoid bone and surrounding tissues without fracture — most common in runners, dancers, and anyone with prolonged forefoot pressure (high heels). Presents as gradual onset forefoot pain under the great toe joint. Sesamoid stress fracture: Incomplete fracture from repetitive cyclic loading — common in distance runners and high-impact dancers. Insidious onset of localized sesamoid tenderness. Acute sesamoid fracture: Complete fracture from a single traumatic event — typically a fall or high-impact landing on the forefoot. Avascular necrosis (AVN): Loss of blood supply to the sesamoid after fracture or severe sesamoiditis — the sesamoid fragments and collapses on X-ray. Bipartite sesamoid: A normal developmental variant where the tibial sesamoid has two smooth-edged components instead of one — must be distinguished from an acute fracture (bilateral X-ray comparison shows symmetric bipartite pattern).
Diagnosis of Sesamoid Pathology
Standard X-rays including a sesamoid axial view (tangential view directly through the sesamoid) are the starting point. MRI is the most sensitive modality: stress reactions show bone marrow edema before fracture lines appear; complete fractures and AVN are clearly delineated. Bone scan detects stress reactions and fractures with high sensitivity. Bipartite vs. fracture distinction: Bipartite sesamoids have smooth, well-corticated edges at the division — acute fractures have irregular, non-corticated edges. Bilateral X-rays help: bipartite sesamoids are commonly bilateral (25% of cases). MRI shows marrow edema in fracture but not in stable bipartite sesamoid.
Treatment: Conservative and Surgical
Conservative treatment (first line): Non-weight-bearing CAM boot for 6-8 weeks for stress fractures and acute fractures. Sesamoid offloading orthotics (dancer’s pad, J-pad cutout beneath the sesamoid, or custom orthotic with metatarsal relief) for sesamoiditis and return to activity after fracture healing. Activity modification and footwear change (avoiding high heels, zero-drop, and thin-soled shoes). NSAIDs and corticosteroid injection for sesamoiditis pain management. Surgical treatment (persistent pain >4-6 months unresponsive to conservative care, AVN, non-union): Sesamoidectomy — excision of the affected sesamoid. Tibial sesamoidectomy is performed through a medial plantar incision, excising the sesamoid while preserving the flexor hallucis brevis tendon attachment. Fibular sesamoidectomy requires careful preservation of the fibular sesamoid ligament complex — complete excision risks hallux varus deformity. Post-sesamoidectomy recovery: 4-6 weeks in a stiff-soled shoe, progressive return to activity.

✅ Pros / Benefits
- MRI differentiates stress reaction, stress fracture, AVN, and bipartite sesamoid accurately
- Conservative non-weight-bearing boot heals most sesamoid stress fractures without surgery
- Tibial sesamoidectomy reliably resolves chronic sesamoiditis with minimal recovery
- Sesamoid offloading orthotics allow return to activity without sesamoid loading
❌ Cons / Risks
- Sesamoid stress fractures have slow healing — 8-12 weeks of non-weight-bearing is often required
- Fibular sesamoidectomy risks hallux varus deformity — requires careful technique
- AVN of the sesamoid with fragmentation typically requires surgical excision
Dr. Tom Biernacki’s Recommendation
Sesamoid injuries are disproportionately common in dancers and distance runners — and they are disproportionately frustrating because the sesamoid has poor blood supply and heals slowly. The key decision point is distinguishing a stress reaction (which responds to conservative care) from an established stress fracture with non-union (which may need sesamoidectomy). MRI early in the course tells us which we’re dealing with. If we see a clean stress reaction, we rest it aggressively and usually avoid surgery. If we see a non-union fragment with AVN, we have the sesamoidectomy conversation early rather than prolonging non-productive conservative care.

Frequently Asked Questions
What is sesamoiditis?
Sesamoiditis is inflammation of the sesamoid bones and surrounding soft tissues beneath the first metatarsal head — without a fracture. It presents as gradual onset pain and tenderness directly under the great toe joint, worsened by push-off activities (running, dancing, wearing high heels). Common in: distance runners, ballet dancers, and anyone with high forefoot loading. Diagnosis: clinical examination plus X-ray to exclude fracture, MRI to identify stress reaction or early stress fracture. Treatment: sesamoid offloading orthotics, activity modification, footwear change, and occasionally corticosteroid injection. Most cases resolve without surgery with appropriate conservative management.
How do I know if I have a sesamoid fracture?
Sesamoid fracture symptoms include: sudden onset severe pain under the great toe joint after a landing or fall (acute fracture), or gradually worsening forefoot pain in a runner or dancer (stress fracture). Physical examination findings: point tenderness directly over the sesamoid bone beneath the 1st metatarsal head, pain with great toe dorsiflexion (which loads the sesamoid), and swelling under the forefoot. Diagnosis requires X-rays (including sesamoid axial view) and MRI for complete evaluation. MRI differentiates sesamoiditis (no fracture), stress fracture, AVN, and bipartite sesamoid — critical for treatment planning.
Can a sesamoid fracture heal without surgery?
Yes — most sesamoid stress fractures and many acute fractures heal without surgery with proper conservative management: non-weight-bearing CAM boot for 6-8 weeks, followed by sesamoid offloading orthotics and gradual return to activity. Success depends on fracture type, blood supply, and patient compliance with offloading. Factors predicting surgical failure of conservative treatment: established avascular necrosis (bone death), non-union after 4-6 months of conservative care, and fragmented sesamoid with chronic pain. When conservative care fails at 4-6 months, sesamoidectomy is indicated and produces reliable pain relief.
What is a bipartite sesamoid?
A bipartite sesamoid is a normal developmental variant in which the tibial sesamoid consists of two smooth-edged pieces instead of one — formed from a failure of the two ossification centers to fuse during development. It occurs in approximately 10-30% of people and is often bilateral. A bipartite sesamoid is asymptomatic and discovered incidentally on X-ray — it does not require treatment unless it becomes painful. Distinguishing a bipartite sesamoid from an acute fracture is essential: bipartite has smooth, well-corticated rounded edges; fractures have sharp irregular edges. MRI confirms no bone marrow edema in a stable bipartite sesamoid.

Frequently Asked Questions
When should I see a podiatrist?
If symptoms persist past 2 weeks, affect your normal activity, or are accompanied by red-flag symptoms (warmth, redness, swelling, inability to bear weight).
What does treatment cost?
Most diagnostic visits and conservative treatments are covered by Medicare and major insurers. Out-of-pocket costs vary by your specific plan.
How quickly can I get an appointment?
Most non-urgent cases see us within 5 business days. Urgent cases (sudden pain, possible fracture) typically same or next business day.
What is Stress fracture?
Stress fracture is a common foot/ankle condition that affects mobility and quality of life. Understanding the underlying cause is the first step in successful treatment. Our podiatrists at Balance Foot & Ankle perform a hands-on biomechanical exam, review your activity history, and use diagnostic imaging when appropriate to identify the root cause—not just treat the symptom. Many patients have been told to “rest and ice” without a deeper diagnostic workup; our approach is different.
Symptoms and warning signs
Common signs of stress fracture include pain that worsens with activity, morning stiffness, swelling, tenderness when palpated, and difficulty bearing weight. If you experience sudden severe pain, inability to walk, visible deformity, numbness or color change, contact our office the same day or visit urgent care—these can signal a more serious injury such as a fracture, tendon rupture, or vascular compromise. Diabetics with any foot wound should seek same-day care.
Conservative treatment options
Most cases of stress fracture respond to non-surgical care: structured rest, supportive footwear changes, custom orthotics, targeted stretching and strengthening protocols, anti-inflammatory medications when medically appropriate, and in-office procedures such as ultrasound-guided injections. We also offer advanced therapies including MLS laser therapy, EPAT/shockwave, regenerative injections, and image-guided procedures. Treatment is sequenced from least invasive to most invasive, and we explain the rationale at every step.
When is surgery considered?
Surgery is reserved for cases that fail 3-6 months of well-structured conservative care, when there is structural pathology (severe deformity, complete tear, advanced arthritis), or when imaging shows damage that will not heal without intervention. Our surgeons have performed 3,000+ foot and ankle procedures and prioritize minimally-invasive techniques whenever appropriate. We discuss recovery timelines, return-to-activity milestones, and realistic outcome expectations before any procedure is scheduled.
Recovery timeline and prevention
Recovery from stress fracture varies based on severity and chosen treatment path. Conservative cases often improve within 4-8 weeks with consistent adherence to the protocol. Post-procedural recovery may range from a few days (in-office procedures) to several months (reconstructive surgery). Long-term prevention involves footwear assessment, activity modification, structured strengthening, and regular check-ins with your podiatrist if you have a history of recurrence. We provide written home-exercise plans and digital follow-up support.
