| Condition | Cause | X-ray Finding | Bone Scan / MRI | Treatment |
|---|---|---|---|---|
| Sesamoiditis | Repetitive overload; inflammation of sesamoid cartilage/tendon interface | Normal sesamoids (no fracture) | Increased uptake (bone scan); bone marrow edema (MRI) | Offloading orthotics; dancer’s pad; NSAIDs; relative rest |
| Acute Sesamoid Fracture | Single traumatic event; axial load on hallux | Irregular fracture line (vs smooth bipartite margins) | Edema at fracture; helpful if X-ray equivocal | NWB cast 6 weeks; bone stimulator; surgical excision if failed |
| Stress Fracture | Repetitive loading; runners, dancers, basketball | Often normal initially; fracture visible at 2–4 weeks | Uptake on bone scan; edema on MRI — more sensitive than X-ray | NWB boot 6–8 weeks; bone stimulator; low-impact only |
| Bipartite Sesamoid | Normal variant (10–30% population); two ossification centers | Smooth, rounded edges; bilateral comparison (usually bilateral) | Minimal uptake (vs fracture = high uptake) | Observation if asymptomatic; treat as sesamoiditis if inflamed |
| Avascular Necrosis (AVN) | Disrupted blood supply; post-fracture or idiopathic | Sclerosis or fragmentation of sesamoid | Decreased signal (MRI T1); confirms AVN | Prolonged offloading 3–6 months; surgical excision if failed |
| Conservative Treatment | Mechanism | Duration | Return to Sport |
|---|---|---|---|
| Dancer’s Pad (J-pad or metatarsal cut-out) | Offloads sesamoid from weight-bearing surface | Weeks to months | With padding in shoe; athlete-specific |
| Carbon fiber insole / rigid orthotic | Limits hallux dorsiflexion; reduces sesamoid compression | Ongoing | As tolerated with pain-free walking |
| NWB Cast / Boot | Complete sesamoid rest for acute fracture or AVN | 6–8 weeks NWB | 3–4 months after fracture healing confirmed |
| Bone Stimulator (PEMF) | Pulsed electromagnetic field accelerates healing | Daily use × 3–6 months | Adjunct; used alongside offloading |
| Corticosteroid Injection | Reduces acute inflammation of flexor hallucis brevis tendon | 1–2 injections | 4–6 weeks post-injection; risk: fat pad atrophy |
Quick answer: Treatment for sesamoid injury sesamoiditis treatment follows a stepwise approach: 1) conservative care first (rest, ice, supportive footwear, OTC anti-inflammatories), 2) physical therapy and targeted exercises, 3) in-office treatments (injections, custom orthotics) if conservative fails at 4-6 weeks, 4) surgery for refractory cases. Most patients resolve at step 1 or 2. Call (810) 206-1402.

The Sesamoid Bones
The sesamoid bones are two small bones embedded within the flexor hallucis brevis tendon beneath the first metatarsal head (ball of the big toe). They function as pulleys for the FHB tendon, bear significant weight during push-off (up to 3x body weight), and protect the plantar surface of the first MTP joint. The medial (tibial) sesamoid is more frequently injured due to its medial position bearing more load.
Sesamoids are classified as bipartite (divided into two parts by a cartilaginous interface) in 10-30% of people — important to recognize on imaging, as bipartite sesamoids can mimic fractures. True fractures show irregular margins, sclerotic edges, and clinical tenderness at the specific sesamoid location.
Types of Sesamoid Injuries
Sesamoiditis: Inflammation of the sesamoid apparatus without structural bone damage. Gradual onset pain, worse with push-off and high heels. Most common in runners, dancers, and athletes. Sesamoid stress fracture: Repetitive loading creates fracture through the sesamoid bone. Localized tenderness directly over the specific sesamoid. MRI shows stress reaction or fracture line. Sesamoid avascular necrosis: Blood supply disruption causes bone death — typically after fracture or corticosteroid injection near the sesamoid. Turf toe: Acute hyperextension injury of the first MTP joint often involving the sesamoid apparatus.
Treatment by Diagnosis
Sesamoiditis: Custom orthotics with sesamoid cutout (relief channel under the sesamoid) eliminate direct weight-bearing pressure — rapid pain relief. Activity modification, anti-inflammatory treatment. Sesamoid stress fracture: non-weight-bearing boot for 6-12 weeks; bone stimulator may accelerate healing. Avascular necrosis: prolonged offloading initially; sesamoidectomy (surgical removal of the affected sesamoid) when conservative care fails — good outcomes with appropriate surgical technique preserving the FHB tendon.
Dr. Tom's Product Recommendations

✅ Pros / Benefits
- Sesamoid orthotic modification provides immediate relief for sesamoiditis without surgery
- Sesamoidectomy has good outcomes preserving first toe function when necessary
- MRI imaging distinguishes bipartite sesamoid from fracture — preventing unnecessary treatment
❌ Cons / Risks
- Sesamoid fractures have inherently poor blood supply — prolonged non-weight-bearing required
- Avascular necrosis is a serious complication of cortisone injections near sesamoids
- Sesamoidectomy, if performed with improper technique, risks hallux valgus or cock-up deformity
Dr. Tom Biernacki’s Recommendation
Sesamoid injuries are one of those conditions where imaging changes the treatment completely. Sesamoiditis without bone damage — orthotic modification and 6 weeks of modified activity. Sesamoid stress fracture — boot for 10-12 weeks. Avascular necrosis — prolonged offloading, possibly sesamoidectomy. The treatment spectrum is enormous, and treating a fracture like sesamoiditis is asking for complications. When I see persistent first MTP plantar pain in a runner or dancer, MRI is non-negotiable.

Frequently Asked Questions
How do I know if I have sesamoiditis or a sesamoid fracture?
Both cause pain under the big toe joint, but sesamoid fracture has more localized tenderness directly over the specific bone, and pain more severe with direct digital pressure. MRI distinguishes sesamoiditis (normal bone signal) from stress fracture (marrow edema) from AVN (dead bone signal) with high accuracy.
How long does sesamoiditis take to heal?
Sesamoiditis with proper offloading (sesamoid relief orthotic) and activity modification: 6-12 weeks. Sesamoid stress fracture: 10-16 weeks in a boot with documented MRI healing. Returning to high-impact activity before imaging confirms healing risks complete fracture and avascular necrosis.
Is sesamoid surgery common?
Sesamoidectomy is a relatively uncommon last resort for sesamoid avascular necrosis or chronic sesamoid pain failing prolonged conservative management. The large majority of sesamoid injuries resolve without surgery. When surgery is needed, outcomes are good if proper technique preserves the flexor tendon and plantar plate.

About 30% of patients I see for foot pain need MORE than a great shoe — they need a structured insole. Below: my complete 2026 orthotic ranking with pros, cons, and the specific patient I’d give each one to.
Best All-Purpose Orthotic for Most Patients
Semi-rigid arch shell + dual-layer cushion + deep heel cup. The orthotic I’ve fitted to more patients than any other for 15 years. APMA-accepted. Trim-to-fit design works in athletic shoes, casual shoes, and most work boots.
✓ Pros
- Semi-rigid arch shell provides true biomechanical correction
- Deep heel cup centers the heel and reduces lateral instability
- Dual-layer cushion (top + bottom) lasts 9-12 months daily wear
- Available in 8 sizes for precise fit
- APMA-accepted and clinically validated
- Lower price than PowerStep Pinnacle Green for equivalent function
✗ Cons
- Too thick for most dress shoes (use ProTech Slim instead)
- Some break-in period required (3-7 days for arch tolerance)
- Not enough correction for severe pes planus or rigid pes cavus
Dr. Tom’s Recommendation: If a patient has run-of-the-mill plantar fasciitis, mild flat feet, or arch fatigue, this is the first orthotic I try. Better value than PowerStep Pinnacle for 90% of patients, which is why I swapped it into our clinic kits three years ago. Sub-$50 typically.
Maximum Motion Control · Flat Feet & Severe Over-Pronation
PowerStep’s most aggressive stability orthotic. Adds a 2°-7° medial heel post on top of the standard PowerStep platform — designed specifically for flat-footed patients and severe pronators who need real corrective force.
✓ Pros
- 2°-7° medial heel post adds aggressive pronation control
- Same trusted PowerStep arch shell, more correction
- Built specifically for flat-foot biomechanics
- Excellent for posterior tibial tendon dysfunction (PTTD)
- Removable top cover for cleaning
✗ Cons
- Too aggressive for neutral-arch patients
- Needs longer break-in (10-14 days) due to stronger correction
- Adds 2-3 mm of stack height — won’t fit slim dress shoes
Dr. Tom’s Recommendation: When a patient comes in with significant flat feet AND symptoms (heel pain, arch pain, knee pain), the Original PowerStep isn’t aggressive enough. The Maxx is what gets prescribed. About 25% of my flat-footed patients end up here.
Low-Profile · Fits Dress Shoes & Narrow Casuals
3 mm slim profile with podiatrist-designed tri-planar arch technology. Engineered specifically to fit inside dress shoes, oxfords, loafers, and women’s flats without crowding the toe box. Vionic was founded by an Australian podiatrist.
✓ Pros
- 3 mm slim profile (vs 7-10 mm for standard orthotics)
- Tri-planar arch technology adds support without bulk
- Built-in deep heel cup despite slim design
- Fits dress shoes WITHOUT having to remove the factory insole
- Trim-to-fit · APMA-accepted
✗ Cons
- Less arch support than full-volume orthotics
- Top cover wears faster than thicker alternatives
- Not enough correction for severe foot deformities
Dr. Tom’s Recommendation: My default when a patient says ‘I need orthotics but I have to wear dress shoes for work.’ Slim enough to fit in oxfords and pumps without the heel sliding out. The single highest-impact change you can make for office workers with foot pain.
Built-In Metatarsal Pad · Morton’s Neuroma · Ball-of-Foot Pain
Standard Pinnacle orthotic with a built-in metatarsal pad positioned proximal to the metatarsal heads — the exact location that offloads neuromas and metatarsalgia. No need for separate met pads or pad placement guesswork.
✓ Pros
- Built-in met pad eliminates DIY pad placement errors
- Specifically designed for Morton’s neuroma + metatarsalgia
- Same trusted PowerStep arch + heel cup platform
- Top cover protects sensitive forefoot skin
- Faster relief than orthotics + add-on met pads
✗ Cons
- Met pad position is fixed (can’t fine-tune individual placement)
- Some patients with very small or very large feet need custom
- Slightly thicker than the standard Pinnacle
Dr. Tom’s Recommendation: If a patient has Morton’s neuroma, sesamoiditis, or generalized ball-of-foot pain (metatarsalgia), this saves a clinic visit and a prescription. The built-in pad placement is anatomically correct for 80% of feet. Way better than DIY met pads.
Adaptive Dynamic Arch · Athletic & Daily Wear
Currex’s flagship adaptive arch technology — the orthotic flexes with your gait instead of fighting it. Different stiffness zones along the length give you targeted support at the heel, midfoot, and forefoot. Available in three arch heights (low/medium/high).
✓ Pros
- Dynamic flex zones adapt to natural gait cycle
- Three arch heights ensure precise fit
- Lighter than rigid orthotics (no ‘heavy foot’ feel)
- Excellent for runners and athletic walkers
- European podiatric design (German engineering)
✗ Cons
- More expensive than PowerStep Original ($55-65 typically)
- Less aggressive correction than Pinnacle Maxx for severe cases
- Three arch heights means you must self-select correctly
Dr. Tom’s Recommendation: I started recommending Currex three years ago for runners who said PowerStep felt ‘too rigid.’ The dynamic flex zones respect natural gait. Best for active patients who walk 8K+ steps daily and don’t need maximum motion control.
Running-Specific · Heel Strike + Forefoot Strike Compatible
Currex’s purpose-built running orthotic. The midfoot flex zone is positioned for runner’s gait mechanics, with a flared heel cushion for heel strikers and a forefoot rocker for midfoot/forefoot strikers. Tested on 1000+ runners during product development.
✓ Pros
- Designed by German biomechanics lab specifically for runners
- Dynamic arch flexes with running gait (not static like PowerStep)
- Three arch heights (low/medium/high)
- Reduces overuse injury risk in mid-distance runners
- Lightweight (no impact on cadence)
✗ Cons
- Premium price ($60-75)
- Not aggressive enough for severe over-pronators (use Pinnacle Maxx)
- Runner-specific design = less ideal for daily walking shoes
Dr. Tom’s Recommendation: If a patient runs 20+ miles per week and has plantar fasciitis or shin splints, this is the orthotic I prescribe. The dynamic flex zones respect running biomechanics in a way that no rigid PowerStep can match. Pricier but worth it for serious runners.
Cavus Foot & High-Arch Patients
Polyurethane base with a deeper heel cup and higher arch profile than PowerStep — built for cavus (high-arched) feet that need maximum cushion and support. The 5-zone cushioning system addresses the unique pressure points of high-arch feet.
✓ Pros
- Deeper heel cup centers the heel for cavus foot stability
- Higher arch profile fills the void under high arches
- 5-zone cushioning addresses cavus foot pressure points
- Polyurethane base lasts 12+ months
- Available in Wide width
✗ Cons
- Too tall/aggressive for normal or low arches
- Won’t fit slim dress shoes
- Pricier than PowerStep Original
- Some patients find the arch height uncomfortable initially
Dr. Tom’s Recommendation: Cavus foot patients are often misdiagnosed and given low-arch orthotics — that makes everything worse. Spenco’s Total Support has the arch profile that high-arch feet actually need. About 15% of my patients have cavus feet; this is what they wear.
Cushion Layer · Standing All Day · Gel Pressure Relief
NOT a true biomechanical orthotic — this is a cushion insole. But for patients who want gel pressure relief instead of arch correction (or to add ON TOP of factory insoles in work boots), this is the best gel option on Amazon.
✓ Pros
- Genuine gel cushioning (not foam pretending to be gel)
- Targeted gel waves under heel and ball of foot
- Trim-to-fit · works in most shoe types
- Sub-$15 price (most affordable option in this list)
- Massaging texture is genuinely soothing
✗ Cons
- ZERO arch support — this is cushion only
- Won’t fix plantar fasciitis or flat-foot issues
- Compresses faster than PowerStep (4-6 months)
- Top cover wears through in high-mileage applications
Dr. Tom’s Recommendation: I recommend these to patients who tell me ‘I just want my feet to stop hurting at the end of my shift’ and who don’t have a biomechanical issue. Construction workers, factory workers, retail. Pure cushion does the job for them.
Tight-Fitting Shoes · Cycling Shoes · Hockey Skates
PowerStep Pinnacle’s slim version of their famous Green insole. The trademark stabilizer cap is preserved but the overall thickness is reduced — works in cycling shoes, hockey skates, ski boots, and other tight-fitting footwear that the standard PowerStep Pinnacle Green can’t fit into.
✓ Pros
- Stabilizer cap centers the heel (PowerStep Pinnacle’s signature feature)
- Slim profile fits tight athletic footwear
- Lasts 12+ months daily wear
- Excellent for cycling shoes specifically
- Built-in odor-control treatment
✗ Cons
- Premium price ($45-55)
- Less cushion than PowerStep equivalents
- Not as aggressive correction as Pinnacle Maxx for flat feet
- The signature ‘heel cup feel’ takes 1-2 weeks to adapt to
Dr. Tom’s Recommendation: If you’re a cyclist with foot numbness, hot spots, or knee pain — this is the orthotic. The stabilizer cap solves cycling-specific biomechanical issues that no other orthotic addresses. Worth the premium for athletes.
