Extensor Tendonitis

The extensor tendons are fibrous tissues that connect the muscles in the front of your lower leg to your toes. Their main job is to lift the toes and foot upward during walking and movement.

The two primary tendons involved are:

• Extensor hallucis longus – lifts the big toe
• Extensor digitorum longus – lifts the second through fifth toes

These tendons travel across the front of the ankle and top of the foot, where they are exposed and have minimal cushioning, making them prone to irritation from pressure or strain.

• Tight or poorly fitting shoes placing pressure across the top of the foot
• Overuse from running, walking uphill, or repetitive foot movements
• Footwear laces tied too tightly
• Ankle sprains or prior foot trauma
• Flat feet or gait abnormalities that increase stress on the extensor tendons

• Sharp or aching pain across the top of the foot
• Increased pain with walking, standing, or wearing shoes
• Swelling or tenderness along the top of the foot or ankle
• Discomfort when flexing the foot or toes upward
• Pain that improves with rest and worsens with activity

Our podiatrists perform a thorough clinical exam to evaluate:

• Location and pattern of pain
• Range of motion and tendon function
• Gait and foot mechanics

In some cases, X-rays, ultrasound, or MRI may be ordered to rule out fractures, joint issues, or other soft tissue injuries.

Most cases of extensor tendonitis respond well to non-surgical treatment, especially when caught early. At SoCal Foot and Ankle Doctors, we develop personalized treatment plans focused on long-term relief and function.

Conservative Treatment Options:

• Rest and activity modification
• Ice therapy to reduce swelling
• Anti-inflammatory medications
• Shoe modifications or switching to more supportive footwear
• Orthotic inserts to correct underlying biomechanics
• Physical therapy and gentle stretching exercises

In rare cases where the condition becomes chronic or resistant to conservative care, advanced interventions such as platelet-rich plasma (PRP) or ultrasound-guided injections may be considered.

If you’re experiencing persistent pain across the top of your foot, schedule a consultation at SoCal Foot and Ankle Doctors.
