A hallux abducto valgus deformity, commonly called a bunion, is a deformity characterized by medial deviation of the great toe, often erroneously described as an enlargement of bone or tissue around the joint at the head of the big toe. There is disagreement among medical professionals about the cause of bunions; some see them as primarily caused by the long-term use of shoes, particularly tight-fitting shoes with pointed toes, while others believe that the problem stems from genetic factors that are exacerbated by shoe use. Bunions occur when pressure is applied to the side of the big toe (hallux) forcing it inwards towards, and sometimes under or over, the other toes (angulation). As pressure is applied, the tissues surrounding the joint may become swollen and tender. In a survey of people from cultures that do not wear shoes, no cases of bunions were found, lending credence to the hypothesis that bunions are caused by ill-fitting shoes. The bump itself is partly due to the swollen bursal sac or an osseous (bony) anomaly on the metatarsophalangeal joint. The larger part of the bump is a normal part of the head of the first metatarsal bone that has tilted sideways to stick out at its top.
Women tend to get bunions more than men. This could be due to the more restrictive footwear they wear, (such as high heels or narrow toe boxes which force the big toe towards the little toes) but women also tend to have looser ligaments, making them slightly more prone. You?re also more likely to get bunions if your parents or grandparents have them.
The dominant symptom of a bunion is a big bulging bump on the inside of the base of the big toe. Other symptoms include swelling, soreness and redness around the big toe joint, a tough callus at the bottom of the big toe and persistent or intermittent pain.
Clinical findings are usually specific. Acute circumferential intense pain, warmth, swelling, and redness suggest gouty arthritis (see Gout) or infectious arthritis (see Acute Infectious Arthritis), sometimes mandating examination of synovial fluid. If multiple joints are affected, gout or another systemic rheumatic disease should be considered. If clinical diagnosis of osteoarthritic synovitis is equivocal, x-rays are taken. Suggestive findings include joint space narrowing and bony spurs extending from the metatarsal head or sometimes from the base of the proximal phalanx. Periarticular erosions (Martel sign) seen on imaging studies suggest gout.
Non Surgical Treatment
Several things can be done to help relive the pain of bunions. These won't make the bunion go away, but they can make the foot more comfortable. Wearing different shoes. Shoes with a wide toe box rather than a pointed one will help. Shoes with lower heels will also help. (High heels throw more of the body's weight on the front part of the foot where the toe joints are.) Padding. Pads placed over the bunion may help reduce the pain. These are available from a drug store or may be available from a foot and ankle surgeon. Avoiding activities that make the pain worse. This includes standing for a long time or other activities that make the bunion sore. Non-steroidal anti-inflammatory drugs. These include aspirin or ibuprofen. They relieve pain and swelling. Applying an ice pack to reduce swelling and pain. Corticosteroid injections. These are not often used in bunion treatment. Injecting corticosteroids sometimes helps if the bursa is inflamed. (Bursa is a fluid-filled sac within a joint to cushion the bones). Orthotic devices. These are devices placed inside a shoe that shift the positioning of the foot. Orthotics help compensate for structural issues that cause foot problems.
The most simple procedure is reducing the bump, and while there will be a little pain and swelling afterwards and your mobility will be restricted, the recovery time is short (ie a few weeks), but it may not fix the underlying cause. More serious ops might involve lasers, robots, cutting bone in the foot and trying to reposition it, and/or inserting pins or wires. It can take months to recover fully and you might need a cast. Mike O?Neill recommends seeking an NHS consultant surgeon who specialises in bunion removal to ensure the best possible outcome. The type of anaesthetic, local or general, will depend on the procedure, but most are day cases and the surgery will take from less than 30 minutes to a couple of hours. Waiting times vary but from your first outpatient appointment to the op would be a minimum of a few months. Private treatment (preferably by an NHS consultant surgeon) is likely to cost thousands of pounds. A new less, invasive procedure called surgical correction of hallux valgus that makes a small incision in the bone has recently been approved for use in the NHS but there is still no conclusive evidence on how effective it is and it is not widely available.
The best way to prevent a bunion is to be proactive in the truest sense of the word. Go over your risk factors. If you know that you pronate or have any problem with the mechanics of your foot, talk with a podiatric physician about the correct types of shoes and/or orthoses for you. If you are not sure whether you have such a problem, the podiatric professional can analyze your foot, your stride and the wear pattern of your shoes, and give you an honest evaluation. Has anyone in your family complained of bunions? Does your job involve a lot of standing, walking or other stress on your feet or toes? Do you exercise? If so, what kind of shoes do you wear for sports? For work? For school? Do you ever feel pain in your toes, or have you noticed a pronounced or increased redness on your big toe, or on the other side of your foot, near your little toe? Make sure you let the doctor know. Keep track of whether any relatives have suffered from arthritis or other joint problems, as well as anything else that might be relevant to your podiatric health. If you?ve suffered sports injuries previously, let the doctor know about that, too. In other words, try to give your health care professional the most honest and thorough background you can, so that he or she can make the best evaluation possible.
