Mechanism
- Tenosynovitis or tendon rupture (Repetitive forceful inversion)
Examination
- “too many toes” in case of rupture
- Weakness with inversion and plantar flexion
Treatment
- Acute: Same as lateral ankle sprains
- Conservative: Rehabilitation, orthotics to address pronation
- Surgical: Tendon transfer, excising the accessory navicular

What is the gold standard method of diagnosing plantar fasciitis? 🔑
Increased tension on the plantar fascia leads to chronic inflammation
- Pes cavus (high arch)
- Pes planus (flat foot)
- Obesity
- Tight Achilles tendon

- Pain can be elicited by hyperextension of the great toe
- Pain is worse in the morning or at the start of weight-bearing activities
Imaging
- Plain films to assess for bony spur
- Ultrasound. Measure thickness of fascia. (gold standard)
Risk Factors
- Tight Achilles tendon
- Pes planus (flat foot)
