Sinus tarsi syndrome is a condition that causes pain on the outer front portion of the ankle, often after an ankle sprain or repeated instability. Many people describe discomfort when walking on uneven surfaces or turning the foot inward.
Because symptoms can overlap with ligament injuries or tendon irritation, proper assessment is important.
Our foot clinic provides professional sinus tarsi syndrome treatment in Toronto focused on relieving pain and restoring ankle stability.
The sinus tarsi is a small canal located between two bones in the rearfoot. It contains ligaments and soft tissue that help stabilize the ankle and subtalar joint during movement.
Sinus tarsi syndrome occurs when this area becomes inflamed or irritated, often due to previous ankle injury or abnormal foot mechanics.
Common contributing factors include:
Previous ankle sprains
Repeated ankle rolling or instability
Flat feet or overpronation
High-impact activities
Improper footwear
Incomplete rehabilitation after injury
The condition may develop gradually or after an acute ankle injury.
You may notice:
Pain on the outer front side of the ankle
Tenderness when pressing into the area
Discomfort when walking on uneven ground
A feeling of ankle instability
Pain that worsens with activity
Symptoms may improve with rest but return during movement.
Treatment focuses on reducing inflammation and improving joint stability.
Clinical assessment and evaluation help confirm diagnosis and rule out ligament tears or fractures.
Custom orthotics may be recommended to improve foot alignment and reduce excessive inward rolling that stresses the sinus tarsi area.
Rehabilitation and strengthening guidance may be provided to improve ankle stability and reduce recurrent irritation.
Bracing or taping techniques may be recommended to support the ankle during activity.
Shockwave therapy may be considered for persistent soft tissue irritation to stimulate healing.
Treatment plans are individualized depending on severity and activity level.
Consider booking an assessment if:
Outer ankle pain persists after a sprain
Walking on uneven surfaces is uncomfortable
The ankle feels unstable
Symptoms continue despite rest
Early intervention can help prevent chronic ankle instability.
If pain on the outer side of your ankle is affecting your comfort or mobility, a professional assessment can help determine the cause and guide appropriate treatment.
