A bunion is a bony deformity of the joint at the base of the big toe. The medical name is hallux valgus. The main sign of a bunion is the big toe pointing towards the other toes on the same foot, which may force the foot bone attached to it (the first metatarsal) to stick outwards. Other symptoms may include a swollen, bony bump on the outside edge of your foot, pain and swelling over your big toe joint that's made worse by pressure from wearing shoes hard, callused and red skin caused by your big toe and second toe overlapping, sore skin over the top of the bunion, changes to the shape of your foot, making it difficult to find shoes that fit. These symptoms can sometimes get worse if the bunion is left untreated, so it's best to see a GP. They'll ask you about your symptoms and examine your foot. In some cases, an X-ray may be recommended to assess the severity of your bunion. Anyone can develop a bunion, but they're more common in women than men. This may be because of the style of footwear that women wear.
Improper footwear. Podiatric physicians have long believed that narrow, poor-fitting shoes with a tight toe box tend to compress the end of the foot, leading to abnormal motion of the foot and pressure over the MTP joint. High-heeled shoes tend to add even more pressure to the toes, as the foot slides downward. Over time, continued pressure will squeeze the toes together, encouraging the deformity. Occupational hazards. Individuals whose jobs place undue stress on their feet are among those who complain of bunions. Ballet dancers, in particular, put great demands on their toes, and thus are often subject to bunions, however, they are not alone. Many professionals whose jobs require a great deal of standing or walking (teachers, police officers, doctors and nurses, etc.) and/or who are required to wear a particular type of shoe or boot as part of a uniform, also are at risk. Athletes such as runners or walkers, who utilize the wrong footwear, may also develop bunions.
SymptomsJust because you have a bunion does not mean you have to have pain. There are some people with very severe bunions and no pain and people with mild bunions and a lot of pain. Symptoms for a bunion may include pain on the inside of your foot at the big toe joint. Swelling on the inside of your foot at the big toe joint. Redness on the inside of your foot at the big toe joint. Numbness or burning in the big toe (hallux). Decreased motion at the big toe joint. Painful bursa (fluid-filled sac) on the inside of your foot at the big toe joint. Pain while wearing shoes, especially shoes too narrow or with high heels. Joint pain during activities. Other conditions which may appear with bunions include corns in between the big toe and second toe. Callous formation on the side or bottom of the big toe or big toe joint. Callous under the second toe joint. Pain in the second toe joint.
Although bunions are usually obvious from the pain and unusual shape of the toe, further investigation is often advisable. Your doctor will usually send you for X-rays to determine the extent of the deformity. Blood tests may be advised to see if some type of arthritis could be causing the pain. Based on this evaluation, your doctor can determine whether you need orthopaedic shoes, medication, surgery or other treatment.
Non Surgical Treatment
There are two ways to treat this pathological foot conditions, conservatively and surgically. Conservative treatment is the first line treatment which consists of splints and orthotic care to reduce the causative factors. Realigning the foot with the aid of an orthotic helps prevent further degeneration and/or reduce symptoms of HAV in any stage of its deformity. Along with orthotic care, patients may require debridement of corns and calluses produced due to extra forces produced on the foot. Orthotics will also help the function of the big toe joint as it allows it to bend in the correct position. Footwear advice is also essential in the conservative care of bunions, HAV, there may be a need to change footwear, so it is able to fit properly and be compliment with orthotics. Surgical correction of bunions, HAV is available, however should only be considered when conservative care has failed to reduce the onset of bunions, HAV. It is only considered if there is a clear sign that it will induce a better quality of life for the patient.
In 2010, the National Institute for Health and Care Excellence (NICE) published guidance about a minimally invasive surgical procedure to treat bunions. The aim of the procedure is to repair the tilting of the big toe. The technique can be carried out under a local anaesthetic or a general anaesthetic, using X-rays or an endoscope for guidance. The type of endoscope used will be a long, thin, rigid tube with a light source and video camera at one end. One or more incisions will be made near the big toe so that bone-cutting instruments can be inserted. These will be used to remove the bunion and to divide one or more bones located at the front of the foot. Wires, screws or plates will be used to keep the divided bones in place. After the procedure, you may need to wear a plaster cast or dressing to keep your foot in the correct position until the bones have healed. You may be given a special surgical shoe that enables you to walk on your heel. As the procedure is relatively new, there's little in the way of reliable evidence regarding its safety or effectiveness.
