What is the appropriate workup and treatment for toe pain?

Workup and Treatment of Toe Pain

Start with weightbearing radiographs of the foot as your initial imaging study for toe pain of unknown etiology, then proceed to MRI without contrast if radiographs are negative or equivocal and pain persists. 1

Initial Clinical Assessment

Focus your history on:

• Mechanism of injury: Hyperextension injuries suggest turf toe (first MTP joint sprain); direct trauma suggests fracture or dislocation 2, 3
• Location specificity: Great toe versus lesser toes; MTP joint versus interphalangeal joints; plantar versus dorsal pain
• Timing: Acute (fractures, dislocations, turf toe) versus chronic exacerbation (sesamoiditis, Morton's neuroma, metatarsalgia) 2
• Activity level: Athletes in football, soccer, basketball have higher turf toe risk 3

On physical examination, assess for:

• Deformity or displacement requiring urgent reduction
• Open wounds necessitating surgical management 4
• Neurovascular status
• Range of motion limitations at MTP and IP joints
• Focal tenderness over sesamoids, metatarsal heads, or webspaces
• Nail fold inflammation (consider retronychia if proximal nail fold is painful with slowed nail growth) 5

Imaging Algorithm

Initial Imaging

Obtain weightbearing radiographs of the foot first - this is the appropriate initial study regardless of suspected etiology 1. Radiographs effectively identify:

• Fractures and dislocations 2
• Sesamoid pathology and bipartite sesamoids 1
• Hallux valgus deformity 6
• Osteoarthritis of the first MTP joint 1
• Freiberg's infraction 2

Important caveat: Radiographs have only 12-56% sensitivity for stress fractures, so negative films don't exclude this diagnosis 1.

Advanced Imaging (When Radiographs Are Negative/Equivocal)

Order MRI foot without IV contrast as your next study 1. MRI is superior for:

• Occult fractures (metatarsals, sesamoids)
• Plantar plate injuries and turf toe grading 7, 3
• Soft tissue pathology (Morton's neuroma, intermetatarsal bursitis)
• Sesamoiditis and sesamoid stress fractures
• Tendon injuries

Ultrasound is an acceptable alternative for plantar fascia pathology, Morton's neuroma, and when dynamic assessment is needed 1, but MRI provides more comprehensive evaluation.

Do not order bone scan, CT, or MRI as initial imaging - these are not supported for first-line evaluation 1.

Treatment Approach by Diagnosis

Acute Injuries

Fractures (non-displaced):

• Buddy taping to adjacent toe
• Rigid-soled shoe or walking boot
• Protected weightbearing for 4-6 weeks 4, 2

Fractures (displaced) or open injuries:

• Surgical referral required for reduction and fixation 4

Dislocations:

• Closed reduction with immobilization 7
• Surgical intervention if unstable or irreducible 4

Turf Toe (First MTP Sprain):

• Grade I: Minimal restriction, taping support, return to play in 3-5 days 3
• Grade II: Immobilization 2-4 weeks, taping when returning to play, expect 2-4 weeks lost playing time 3
• Grade III: Immobilization 4-6+ weeks; surgical repair if complete plantar plate disruption, severe instability, or bony injury present 7, 3. Less than 2% require surgery, but those that do are typically grade III 3

Chronic/Overuse Conditions

Hallux Rigidus (First MTP Osteoarthritis):

• Arch-contouring foot orthoses show no clinically important benefit over sham 8
• Shoe-stiffening inserts show no clinically important benefit over sham 8
• Single intra-articular hyaluronic acid injection shows no clinically important benefit over placebo 8
• Consider rocker-sole footwear to reduce MTP joint motion 1
• Surgical referral for recalcitrant cases 9, 6

Sesamoiditis:

• Offloading with metatarsal pads or dancer's pads
• Rigid-soled shoes
• Activity modification
• NSAIDs for pain control 6

Morton's Neuroma:

• Wider toe box footwear
• Metatarsal pads
• Corticosteroid injections
• Surgical excision if conservative measures fail 2

Metatarsalgia:

• Metatarsal pads for pressure redistribution
• Proper footwear with adequate cushioning
• Activity modification 2

Critical Pitfalls to Avoid

1. Don't skip radiographs - even when clinical suspicion is high for soft tissue injury, radiographs exclude bony pathology and are the guideline-recommended first step 1

2. Don't assume bipartite sesamoid is fracture - comparison views or MRI may be needed for differentiation 1

3. Don't miss décollement injuries or proximal tendon ruptures - these are rare but require surgical intervention 4

4. Don't rely on evidence-poor treatments for hallux rigidus - orthoses, shoe inserts, and hyaluronic acid injections lack proven benefit 8

5. Don't underestimate turf toe severity - grade III injuries require 4-6+ weeks recovery, and about 30% of athletes with higher-grade injuries fail to return to prior performance level 3

Surgical Referral Indications

Refer to orthopedic surgery or podiatry when:

• Displaced fractures or open injuries 4
• Grade III turf toe with complete plantar plate disruption 7, 3
• Irreducible dislocations 4
• Failed conservative management after 3-6 months
• Progressive deformity
• Significant functional limitation despite appropriate conservative care 9, 6
