Ankle and Foot Pain: Sinus Tarsi and Tarsal Tunnel in Laval

Sinus Tarsi: What is it?

The sinus tarsi is an anatomical space between the talus and calcaneus, at the outer aspect of the ankle. Sinus tarsi syndrome corresponds to pain or instability from this region, often associated with ligamentous or biomechanical involvement.

Symptoms may include pain on the outer ankle, instability or insecurity sensation when walking, increased pain on uneven terrain and pain after a sprain or repeated sprains. Clinical data associate the syndrome with repeated ankle sprains, chronic instability, biomechanical imbalances, flat foot or hyperpronation and repeated mechanical overload.

Tarsal Tunnel Syndrome

Tarsal tunnel syndrome corresponds to compression of the posterior tibial nerve or its branches, in an anatomical canal on the inner aspect of the ankle. It is a nerve condition, distinct from mechanical or joint pain.

Symptoms may include pain on the inner ankle, burning, tingling or numbness sensations, radiation toward the sole or toes and symptoms increased with prolonged standing or walking. Neurological symptoms are a key element of differential diagnosis. Associated factors include biomechanical imbalances, flat foot or hyperpronation, previous trauma, local edema or inflammation and prolonged mechanical overload.

Podiatric Evaluation

Management begins with a complete podiatric evaluation: clinical examination of the ankle and foot, biomechanical analysis, gait observation, targeted clinical tests and trauma history evaluation. Ultrasound and X-ray can complete the diagnosis.

Management Options

Conservative Approaches

Custom foot orthotics when indicated, activity and load adjustment, personalized clinical advice and shoe modifications.

Advanced Therapeutic Modalities

When symptoms persist: PRP (platelet-rich plasma) in certain targeted situations, hyaluronic acid when relevant, other complementary modalities adapted to the condition.

Surgery

In some situations, and only after failure of conservative and advanced treatments, surgical options may be discussed as a last resort, whether for sinus tarsi or tarsal tunnel.

When to See a Podiatrist?

Consultation is recommended if pain persists or worsens, if there is instability or neurological symptoms, if pain limits daily or sports activities or if ankle sprains are repeated.
