Understanding Sesamoid Injuries

The sesamoid bones are two small, pea-shaped bones embedded within the flexor hallucis brevis tendon beneath the first metatarsophalangeal (MTP) joint — the big toe knuckle. These bones function as a pulley for the flexor tendon, absorbing enormous pressure with every step. Sesamoid injuries range from sesamoiditis (chronic inflammation without fracture) to stress fracture to acute traumatic fracture. At Balance Foot & Ankle, Dr. Tom Biernacki has extensive experience distinguishing these conditions and tailoring treatment accordingly.

Who Gets Sesamoid Injuries?

Sesamoid injuries are a signature problem in dancers, runners, football players, and anyone who spends prolonged time on the balls of their feet. High-heeled shoes push weight forward onto the sesamoids and accelerate injury. Patients with high-arched (cavus) feet or a prominent first metatarsal head are biomechanically predisposed. Acute fractures can occur with a single forceful landing or jump, while stress fractures develop gradually from repetitive loading.

Diagnosis: Separating Fracture from Bipartite Sesamoid

The most challenging diagnostic issue in sesamoid injuries is distinguishing a fracture from a bipartite sesamoid — a normal variant in which the medial sesamoid develops from two ossification centers rather than fusing into one bone. Bipartite sesamoids occur in roughly 10–33% of the population and can mimic fracture on X-ray. Dr. Biernacki uses comparison views of the contralateral foot, MRI (bone marrow edema indicates fracture), and bone scan (hotspot indicates active pathology) to differentiate the two. Getting the diagnosis right is essential — treating a bipartite sesamoid as a fracture leads to prolonged unnecessary immobilization.

Conservative Treatment of Sesamoid Injuries

Non-surgical management is first-line for all sesamoid conditions that have not failed prior conservative care. Dr. Biernacki’s protocol includes a well-padded sesamoid-relief orthotic with a cutout beneath the affected bone, transition to low-heeled stiff-soled footwear, activity modification, taping to restrict first MTP dorsiflexion during healing, and anti-inflammatory medication or targeted corticosteroid injection. Stress fractures require strict non-weight-bearing in a boot for 6–8 weeks followed by gradual return to activity.

Surgical Options: Sesamoidectomy

When conservative care fails after 3–6 months, or in cases of avascular necrosis (bone death) of the sesamoid, surgical sesamoidectomy — partial or complete removal of the affected sesamoid — is considered. Dr. Biernacki performs sesamoidectomy through a minimal incision approach, carefully preserving the flexor tendon mechanism. Complete medial sesamoid removal can cause hallux valgus drift, and complete lateral sesamoid removal can cause hallux varus — Dr. Biernacki’s surgical technique minimizes these risks through meticulous tendon repair.

Recovery After Sesamoid Treatment

Conservative care recovery varies widely — sesamoiditis may resolve in 6–12 weeks with proper off-loading, while stress fractures require 12–16 weeks of protected weight-bearing before return to high-impact activity. After sesamoidectomy, patients are typically in a surgical shoe for 3–4 weeks followed by athletic footwear at 6–8 weeks, with full athletic return at 3–4 months. Dr. Biernacki coordinates with physical therapy to restore first MTP range of motion and push-off strength — critical for runners and dancers.

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.

In-Office Treatment at Balance Foot & Ankle

If home treatment isn’t providing relief for your sesamoiditis, our podiatry team at Balance Foot & Ankle can help with same-day evaluations and advanced in-office care.

More questions patients ask

What are the sesamoid bones and what causes sesamoiditis vs. a sesamoid fracture?

The sesamoid bones are two small pea-sized bones embedded within the flexor hallucis brevis tendon beneath the first metatarsal head -- the medial (tibial) sesamoid and the lateral (fibular) sesamoid -- that function as a pulley to increase the mechanical advantage of the FHB tendon, protect the flexor hallucis longus tendon, and absorb the high compressive forces beneath the first metatarsal head during push-off; sesamoid pathology ranges from inflammation without structural disruption (sesamoiditis) to acute fracture. The sesamoids' structural role: the sesamoids are located in the two grooves on the plantar surface of the first metatarsal head; they bear up to 3 times body weight during normal push-off; in high-heeled shoes or athletic activities requiring repeated push-off (sprinting, ballet, gymnastics, basketball), the load is dramatically increased; the medial sesamoid is the larger of the two and is more commonly injured (approximately 75% of sesamoid injuries); Sesamoiditis (inflammation without fracture): chronic, gradual onset of pain beneath the first MTP joint; worsens with push-off activities; tenderness on direct palpation of the sesamoid (applying pressure directly upward through the plantar soft tissue onto the sesamoid bone); X-ray: the sesamoid appears normal or may show fragmentation consistent with a bipartite sesamoid (a normal anatomical variant present in 10-30% of people -- the medial sesamoid has two separate ossification centers that failed to fuse; this is NOT a fracture); MRI: bone marrow edema within the sesamoid without a fracture line -- confirms sesamoiditis; Sesamoid fracture: acute onset after a specific traumatic event (a fall, a misstep, a direct blow); immediate plantar first MTP pain; X-ray: a fracture line through the sesamoid; the key distinction: the fracture line in an acute fracture has irregular, sharp edges; a bipartite sesamoid has smooth, well-corticated margins (the body filled in the gap between the two centers over years); MRI: a fracture line with surrounding bone marrow edema, different from the bilateral absence of edema typical of a bipartite sesamoid; stress fracture: gradual onset (like sesamoiditis) but with a true fracture line on MRI; caused by repetitive loading exceeding the sesamoid's remodeling capacity.

How are sesamoid fractures and sesamoiditis treated, including when sesamoidectomy is needed?

Sesamoid fracture and sesamoiditis treatment begins with aggressive conservative management to offload the sesamoid and reduce inflammation -- most cases respond to conservative care; surgical sesamoidectomy is a last resort reserved for fractures that fail to heal after prolonged non-operative treatment and for refractory sesamoiditis. Conservative treatment for sesamoiditis: offloading the sesamoid is the primary goal; metatarsal pads: a J-shaped pad (U-shaped pad) with the opening positioned under the sesamoid -- the pad surrounds but does not contact the painful sesamoid; removes direct pressure during push-off; custom orthotics: a custom orthotic with a sesamoid cutout (a hollow relief beneath the sesamoid) and a metatarsal pad redistributes weight away from the sesamoid to the lesser metatarsals; footwear modification: a stiff-soled shoe reduces the dorsiflexion moment at the first MTP and decreases sesamoid compressive force; avoid barefoot walking (which maximizes sesamoid loading); activity modification: reduce push-off intensive activities (sprinting, jumping, ballet); substitute low-impact cross-training (cycling, swimming); physical therapy: joint mobilization, ultrasound, intrinsic foot muscle strengthening; NSAIDs and ice: for acute inflammatory flares; corticosteroid injection: peribursal injection near the sesamoid reduces acute inflammation; not injected into the sesamoid itself; Conservative treatment for sesamoid fractures: in addition to offloading (same as above), acute sesamoid fractures are immobilized: a short-leg non-weight-bearing cast or walking boot for 6-8 weeks; bone stimulator (low-intensity pulsed ultrasound): may accelerate healing in delayed union; the medial sesamoid has notoriously poor healing capacity due to limited blood supply; non-union is common (up to 30-40%) even with appropriate conservative management; Sesamoidectomy (surgical removal): indications: fracture non-union after 6 months of non-operative treatment; refractory sesamoiditis unresponsive to 6 months of conservative care; avascular necrosis of the sesamoid; procedure: the affected sesamoid is surgically removed through a plantar medial (medial sesamoid) or plantar lateral (lateral sesamoid) incision; the FHB tendon is meticulously repaired after sesamoid removal to prevent great toe deformity; medial sesamoidectomy carries a risk of hallux valgus (if not repaired properly); lateral sesamoidectomy carries a risk of hallux varus; both sesamoids should never be removed simultaneously (creates catastrophic hallux instability); Recovery: weight-bearing in a surgical shoe from day 1; return to sports shoe at 3-4 weeks; return to full sport: 6-8 weeks; outcomes: 85-90% pain resolution.
