Overview
A bunion (hallux valgus) is a deformity of the base joint of the big toe. The cause is not clear in many cases. The deformity may cause the foot to rub on shoes, which may cause inflammation and pain. Good footwear is often all that is needed to ease symptoms. An operation to correct the deformity is an option if good footwear does not ease symptoms.
Causes
Hereditary and shoe gear are probably the most likely causes. Tight pointy shoes (and high heels) may promote the formation of a bunion. A bunion may develop rapidly or develop slowly over time. Some people have bunions in their teens while others only develop a bunion later in life. Bunions come in a variety of sizes - from small to severe. In some cases, the big toe may push against the second toe, and may result in pain and a hammer toe, or progress onto a severe disfiguring foot deformity. Depending on your overall health, symptoms and severity of the bunion, the condition may be treated conservatively and/or with surgery.
Symptoms
Red, thickened skin along the inside edge of the big toe. A bony bump at this site. Pain over the joint, which pressure from shoes makes worse. Big toe turned toward the other toes and may cross over the second toe.
Diagnosis
Orthopaedic surgeons diagnose bunions on the basis of physical examination and weight bearing x-rays. Two angles are assessed, the intermetatarsal angle, that is between the first and second metatarsals (the bones that lead up to the base of the toes). If this angle exceeds 9? (the angle found in the healthy foot) it is abnormal and referred to as metatarsus primus varus. the hallux valgus angle, that is, the angle of the big toe as it drifts toward the small toe. An angle that exceeds 15? is considered to be a sign of pathology.
Non Surgical Treatment
Wearing the right shoes, using shoe inserts (orthoses) and padding, and taking painkillers can all help to ease your symptoms of a bunion. However, these treatments can?t cure a bunion or stop it getting worse. If you have severe pain or discomfort from a bunion, you may be advised to have an operation to correct it. One of the most important things you can do is to wear the right footwear. You should try to wear flat, wide-fitting shoes with laces or an adjustable strap that fits you properly. You may also want to place a bunion pad over your bunion to give it some protection from the pressure of your shoes. You can usually buy these pads from a pharmacy, or get them from your podiatrist or chiropodist. He or she may also recommend a shoe insert, which can be moulded specifically to your foot. Shoe inserts aim to reduce the pain of your bunion by improving how you walk. You can take over-the-counter painkillers, such as paracetamol or ibuprofen, to help relieve the pain and inflammation of your bunion. Always follow the instructions in the patient information leaflet that comes with your medicine. Medicines give temporary relief but they won?t be able to cure your bunion or prevent it from getting worse. If you have a bunion as a result of underlying arthritis, your doctor may prescribe specific medicines to treat this.
Surgical Treatment
There are many different procedures described to correct bunions. You should be aware that usually just shaving the bunion off, although it is attractive and minimally invasive, is usually not enough. Initially the foot will look much better but with time the bunion will recur. Arthrodesis refers to surgery performed on the great toe joint where the joint is fused. This is usually reserved for people with very severe deformities when other surgical options are impossible. Bunionectomy refers to the simple removal of the bunion itself. This is seldom used because it doesn?t correct the underlying bone problems. Osteomety is the commonest surgical procedure. The bone is cut and the bones realigned and pinned in place until they heal so that the underlying bone deformity is corrected and the bunion will not recur. The resection arstplasty refers to the removal of the toe joint and this creates a flexible scar that functions as the joint instead. In the past there has been some interest in implanting artificial joints but this has fallen out of favor due to the fact that they usually do not hold up with the normal every day stress that people put their feet through.
Prevention
Choosing footwear that fits correctly, especially low heeled shoes with plenty of space for the toes, is one of the main ways that bunions can be prevented. Always stand when trying on shoes to ensure they still fit comfortably when the foot expands under your body weight. Try shoes on both feet, and select the size appropriate for your larger foot. Use an extra insole if one shoe is looser than the other. Do not cramp the larger foot. People prone to flat-footedness should consider the use of arch supports, orthotic shoe inserts or special orthotic shoes to prevent or delay the development of bunions.
