Knowing how bunions develop is helpful in selecting the appropriate bunion treatment. In general, most bunion deformities are a result of foot structure and function which are genetic. As the heel strikes the ground when walking, the joints of the foot unlock and absorb impact. Referred to as pronation, the arch collapses causing the feet to flatten. This flattening causes excessive tension of the tendon in the upper mid-foot that enables the big toe to bend upward. The tendon contracts which then forces the big toe to be pulled laterally toward the second toe. It can take many years for a bunion to develop, and especially to the point of pain. One can have a bunion but not yet experience any bunion pain. Conversely, one can suffer from bunion pain without having a severe deformity.
No single cause or set of causes for bunions has been identified, although gender-women develop them more frequently than men-and heredity play a role. In addition, the foot gradually widens with age as the ligaments that connect the bones in the forefoot become more lax. Contrary to what many people believe, ill-fitting footwear is not the cause of bunions. In fact, bunions are found in populations all over the world, including among those who never wear shoes. Shoes that are too tight can, however, contribute to the progression of the condition. Bunions are often bilateral, that is, appearing in both feet. Although bunions are usually seen in people who are middle-aged or older, there are adolescents who are diagnosed with the condition, usually the result of a congenital problem.
The initial symptom may be pain at the joint prominence when wearing certain shoes. The joint capsule may be tender at any stage. Later symptoms may include a painful, warm, red, cystic, movable, fluctuant swelling located medially (adventitial bursitis) and swellings and mild inflammation affecting the entire joint (osteoarthritic synovitis), which is more circumferential. With hallux limitus or rigidus, there is restriction of passive joint motion, tenderness at the dorsolateral aspect of the joint, and increased dorsiflexion of the distal phalanx.
Your doctor will ask questions about your past health and carefully examine your toe and joint. Some of the questions might be: When did the bunions start? What activities or shoes make your bunions worse? Do any other joints hurt? The doctor will examine your toe and joint and check their range of motion. This is done while you are sitting and while you are standing so that the doctor can see the toe and joint at rest and while bearing weight. X-rays are often used to check for bone problems or to rule out other causes of pain and swelling. Other tests, such as blood tests or arthrocentesis (removal of fluid from a joint for testing), are sometimes done to check for other problems that can cause joint pain and swelling. These problems might include gout , rheumatoid arthritis , or joint infection.
Non Surgical Treatment
Most of the time, non-surgical (conservative) treatment can control the symptoms of a foot bunion or bunionette. These include. Appropriate Footwear, changing to wide fitting footwear reduces the pressure on the big toe and prevents shoes from rubbing on the bony lump. When possible, go barefoot Toe stretchers are a really simple way to reduce foot bunion pain. Toe Stretchers, wearing toe spaces that fit in-between the toes help to stretch the muscles and ligaments around the toes, improving the alignment and relieving pain. Find out more about how these work in the Toe Stretcher section. Painkillers, your doctor may prescribe or recommend over-the-counter medication to reduce the pain and inflammation. Foot bunion correctors can be worn in your shoe to help realign your foot if you suffer from foot bunions. Orthotics. There are a number of over-the-counter shoe inserts that can help relieve symptoms. Bunion correctors work by realigning the bones in your foot to reduce pressure on the affected toe. There are both day-time and night-time splints on the market, although the evidence of their effectiveness is lacking. Ice. Applying ice packs to the foot can help reduce pain and inflammation. Bunion pads help to reduce any friction on your big toe. Bunion Pads. You can also get protective foot cushions that sit over the skin to prevent the hallux abducto valgus rubbing on your shoes.
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.
