Hallux Valgus

Have you noticed a bump at the base of your big toe? This deformity, known as hallux valgus or a 'bunion,' is one of the most common foot conditions. As specialized physiotherapists, we regularly see patients who are concerned about this deformity.

Good news: the majority of people with hallux valgus experience no symptoms.¹ For those who do experience pain, conservative treatment is often very effective.

What science teaches us:

• Deformation does not always cause pain
• Cosmetic surgery can create pain that did not exist before²
• Physiotherapy offers excellent results without surgery

This guide will help you understand your hallux valgus, recognize when to seek professional advice, and discover treatment options. For an overview, consult our complete guide to physiotherapy.

What is Hallux Valgus (Bunion)?

Hallux valgus is a deformity of the big toe that deviates towards the second toe. This deviation creates a bony protrusion at the base of the toe, called a 'bunion' in Quebec. It is the most common forefoot deformity, much like knee osteoarthritis is common in the lower limb.

This condition affects approximately 23% of adults aged 18 to 65 and up to 35% of older individuals.³ The metatarsophalangeal joint (the joint at the base of the big toe) gradually becomes misaligned.

Having hallux valgus does not necessarily mean experiencing pain. The majority of people with this deformity live perfectly well without symptoms, similar to cervical osteoarthritis where the presence of changes does not equate to the presence of pain.

What Causes Hallux Valgus?

Hallux valgus results from several combined factors rather than a single cause, similar to other degenerative conditions like hip osteoarthritis.

What are the Symptoms of Hallux Valgus?

The majority of people with hallux valgus experience no symptoms.¹ The visible deformity does not automatically translate into pain.

For those who develop symptoms:

Pain in the big toe joint : This is the most common symptom. The pain can be dull or sharp depending on your activities. Pain often increases when you:

• Move the toe at the end of the movement
• Walk for long periods or go grocery shopping
• Run or exert yourself
• Wear shoes that are too tight

Inflammatory signs : After overexertion, you may experience swelling, redness, and warmth at the base of your big toe. If the pain persists for several days despite rest, it could indicate more significant inflammation requiring a physiotherapy assessment.

How is a bunion (hallux valgus) diagnosed?

Diagnosis is based on your symptom history and a clinical examination. This condition is easily visible and palpable.

Your healthcare professional will assess:

Visual observation : The deviation angle and protrusion are visible to the naked eye. Mobility examination : The professional moves your toe to assess the range of motion and identify painful movements, similar to a neck pain assessment. Gait analysis : Observing how you walk reveals compensations or biomechanical issues. Imaging : X-rays are not always necessary. They can be used to measure the angle of deformity or to plan surgery.¹ For conservative treatment, a clinical examination is sufficient, similar to most musculoskeletal conditions.

When should you seek physiotherapy for hallux valgus?

Consult a physiotherapist if you have symptoms or if your doctor has ruled out other causes. A physiotherapist can help reduce pain and improve your function.

In Quebec, physiotherapists have direct access. You can book an appointment directly without seeing a doctor first. If your condition requires it, your physiotherapist will refer you to the appropriate specialist.

You can also seek advice and exercises if you notice a loss of flexibility, even without pain.

Good reasons to consult us:

• Pain limiting your daily activities
• Pain that persists despite rest
• Loss of toe mobility
• Difficulty walking normally
• Worry about it getting worse

How does physiotherapy treat bunions (hallux valgus)?

Your physiotherapist will conduct a detailed assessment to determine the precise cause of your pain. Key point: the deformity itself is not necessarily what's causing your pain.

The evaluation includes:

• Joint mobility
• Nerve gliding
• Movement quality
• Strength and stability

Based on the results, your physiotherapist will:

• Mobilize your toe to reduce pain and improve movement

• Provide you with specific exercises targeting the intrinsic muscles of the foot (small, deep muscles), similar to strengthening exercises for other areas

• Teach you motor control exercises to help you better control your movements

• Guide you on how to pace your activities to optimize healing, an important principle in managing any musculoskeletal pain

• Advise you on your posture and footwear

What home exercises can you do for a bunion (hallux valgus)?

If you have symptoms, reduce activities that cause too much pain and gradually resume them. The goal is to find the right balance, not to stop moving entirely. This principle also applies to other conditions like plantar fasciitis.

Helpful tips:

• Wear less narrow shoes with a wide toe box that respects the natural shape of your foot

• Stretch your big toe upwards several times a day without causing pain

• Avoid high heels if they increase your pain

• Engage in low-impact activities such as cycling or swimming

If there's no improvement after 10 days, consult a physiotherapist. An assessment will help identify the specific causes and establish a tailored plan.

When is surgery necessary for a bunion (hallux valgus)?

If you have no symptoms : Surgery is strongly discouraged for cosmetic correction. It can create pain that wasn't present before.² Doctors do not correct an asymptomatic deformity. If you have symptoms : Surgery should be a last resort. Start with several weeks of physiotherapy. Conservative treatment works in most cases, just as it does for most foot and ankle conditions.

Surgical decisions should be made with an orthopedic surgeon after conservative treatment options have been exhausted.

How to prevent bunions from getting worse?

While you can't change your genetics, you can limit its progression and prevent symptoms.

Choose appropriate footwear : Opt for a wide toe box that allows free movement. Avoid pointed shoes. This recommendation also applies to other foot conditions. Maintain mobility : Practice gentle big toe stretches for a few minutes daily. Monitor changes : Consult promptly if the deformity progresses or if symptoms appear. Early detection allows for better management. Adapt your activities : Modify painful activities or alternate with less strenuous activities for your foot. This principle of active pain management promotes recovery.
