Bunions

Bunions are a common foot problem that affects millions of people worldwide. They can cause discomfort, pain, difficulty walking, and balance problems.

What Are Bunions?

A bunion, medically known as hallux valgus, is a bony bump that forms at the base of the big toe. This bump develops when the big toe pushes against the adjacent toe, causing the joint at the base of the big toe to stick out. Over time, this misalignment can lead to swelling, redness, and pain around the joint.

Bunions are not just a cosmetic issue; they can interfere with normal foot function. The deformity can make it difficult to find comfortable shoes and may cause pain while walking or standing for long periods. The first toe is used heavily in maintaining balance while standing and walking, and having the toe move into an abnormal position can adversely affect your ability to maintain your balance and can increase your risk of falls.

The Physiology Behind Bunions

The foot is a complex structure made up of bones, joints, ligaments, and tendons that work together to support weight and allow movement. The big toe joint, called the first metatarsophalangeal (MTP) joint, plays an important role in balance and propulsion during walking.

In a healthy foot, the big toe points straight ahead. In the case of a bunion, the 1st MTP joint becomes misaligned. The big toe angles toward the second toe and the first metatarsal bone (the long bone behind the big toe) shifts outward, causing the joint to protrude outward, forming the characteristic bump. A tailor's bunion, or bunionette, is essentially the same, just on the other side of the foot. The 5th MTP joint becomes misaligned, and the 5th toe deviates towards the 4th.

Having a prominent bump at the 1st (or 5th) MTP joint does not mean you have, or will necessarily get, a bunion/bunionette. Similarly, up to 15° of outward deviation of the first toe is considered normal. In looking at foot structure, it's important to compare both sides. This is why a foot care practitioner will always ask to see both feet when there is a complaint of pain or deformity in one foot. Feet come in many shapes and sizes, and that's normal!

This misalignment can cause inflammation of the surrounding tissues, leading to pain and swelling. Over time, the joint may become stiff and arthritic, further limiting movement. The first toe may eventually either overlap or underlap the second toe, causing pain, pressure, and occasionally wounds - often from the nail of the second toe cutting into the first toe.

Causes of Bunions

Genetic Predisposition: Bunions often run in families, suggesting a genetic component. Some people inherit foot shapes that make them more prone to bunions, such as flat feet or low arches, which can increase stress on the big toe joint.

Footwear Choices: Wearing tight, narrow, or high-heeled shoes can increase pressure on the toes and contribute to bunion formation. Shoes that crowd the toes force the big toe to bend inward, accelerating joint misalignment.

Foot Injuries: Trauma or injuries to the foot can alter the alignment of bones and joints, potentially leading to bunions.

Medical Conditions: Certain conditions, such as arthritis (especially rheumatoid arthritis), can cause joint inflammation and deformities, increasing the risk of bunions.

Abnormal Foot Mechanics: Overpronation (excessive inward rolling of the foot) and other gait abnormalities can place uneven pressure on the big toe joint, promoting bunion development.

Treatment Options for Bunions

Treatment depends on the severity of the bunion and the level of discomfort. Options range from conservative measures to surgical intervention.

Conservative Treatments

• Footwear changes: Choose shoes with a wide toe box, low heels, and good arch support to reduce pressure on the bunion. It can be difficult to find shoes that fit properly when there is a significant deviation of the first toe. A Pedorthist can modify your shoes to accommodate the foot shape, by either stretching the material or even adding a patch.

• Padding and taping: Protective pads can cushion the bunion, and taping can help keep the foot in a normal position.

• Orthotic devices: Custom or over-the-counter shoe inserts can correct abnormal foot mechanics and relieve pressure.

• Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) can reduce pain and inflammation.

• Physical therapy: Exercises to strengthen foot muscles and improve joint mobility may help.

  
  

Surgical Treatment

If conservative measures fail and pain or deformity worsens, surgery may be necessary. Surgical options vary but generally involve realigning the bones, removing the bony bump, and often fusing the joint with something called a K-wire. This surgery is often done with either a spinal anaesthetic or a nerve block, and likely will not require a general anaesthetic. Surgery aims to relieve pain and restore normal foot function but requires a recovery period of approximately 6-8 weeks where you will be off your feet. Discuss the risks and benefits with your doctor, who can refer you to an Orthopedic surgeon who specializes in feet and ankles. Correcting a severe bunion can significantly improve both quality of life and mobility.

What about those bunion correctors I saw advertised online? Well, you'll notice they aren't listed in this section. Like many online "cures," they don't actually reverse the problem. Bunion correctors (splints, spacers) do not permanently cure or reverse bunions, but they can effectively relieve pain and slow progression. They provide temporary realignment while worn but cannot restructure the bone or fix the underlying ligament/muscle imbalance that causes the deformity.

Home Management

Wear good shoes: Prioritize footwear that fits well and does not squeeze the toes in any direction. Limit heels to 1" (2.5 cm) or lower. Think of your everyday shoes as personal protective equipment, rather than fashion. They are there to protect your feet from injury, rather than cause one! It's ok to have some shoes that are for fashion, but they should only be worn for short periods on special occasions. Shoes are also an investment. It is better to have fewer pairs of high-quality footwear, rather than many pairs of cheap shoes. Be sure to buy shoes that fit properly, and do not fixate on the size. Much like clothing, shoe sizes are not completely standardized between manufacturers.

Use bunion pads +/- toe spacers: These pads cushion the bunion and reduce friction. There are several types, including adhesive, gel, and gel with sleeve. Toe spacers keep the toes from overlapping. They are available in both gel and foam, with gel being much longer-lasting.

Maintain a healthy weight: Excess weight increases pressure on the feet and can speed the progression of bunions as well as increasing pain.

Avoid prolonged standing: Rest your feet when possible to reduce stress on the bunion. Bunions are not just "sore feet," they are a medical condition and you can request accommodation from your employer.

Massage the area: Gentle massage can improve circulation and relieve discomfort. Gently stretching out the toes with your hands to pull them back to "normal" position can improve pain. If it causes pain, stop.

Involving the Professionals

If home treatments do not relieve pain, or if the bunion worsens, seek medical advice. If the joint becomes red and swollen, seek urgent medical attention, especially if it is accompanied by fever and increased pain.

See your foot care nurse regularly if you have difficulty keeping your nails trimmed or if the nails are thick, especially if the toes overlap. A foot care nurse will monitor the skin & nail health of the toes, the progression of the bunion, and can recommend or provide many padding options that are not readily available in pharmacies.
