A bunion is a very common foot deformity that develops over the first metatarsal phalageal joint of the big toe of the foot. The joint that joins the big toe to the foot is called the first MTP joint. When it becomes prominent and the big toe starts to become crooked this is known as a bunion. The term referring to deformity of the big toe as it becomes crooked is called Hallux Valgus. It is the bump itself that is known as the bunion. When it gets red and swollen over the bunion because it gets sore this is usually due to an inflamed soft tissue over the underlying bone.
Bunions are the byproduct of unnatural forces and motion being applied to the joints and tendons of your foot over a prolonged period of time. They can also be caused by traumas to the foot as well as congenital deformities. Occupations or athletic activities that place abnormal stress on your feet can also lead to the formation of bunions. Bunions have a tendency to run in families, but it?s not the bunion itself that is hereditary. It?s the the foot type which *causes* the bunion that is hereditary. Also, wearing shoes such as high heels that do not distribute your body weight evenly can lead to bunions, which explains why so many women suffer from bunions.
SymptomsThe major symptom of bunions is a hard bump on the outside edge of the foot or at the base of the big toe. Redness, pain and swelling surrounding or at the MTP joint can also occur.
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
In the early stages of the formation of a bunion, soaking feet in warm water can provide temporary relief. The best way to alleviate the pain associated with bunions is to wear properly fitting shoes. Shoes designed with a high, wide toe box (toe area) are recommended for people suffering from forefoot disorders, such as bunions. Shoes with rocker soles will unload pressure to the bunion area. Orthotics are also recommended for this condition to provide extra comfort, support, and protection. Other conservative treatments include using forefoot products designed to accommodate and relieve bunions such as bunion shields, bunion night splints, and bunion bandages. These conservative treatments can limit the progression of the bunion formation, relieve pain and provide a healthy environment for the foot.
Bunion surgery is most often a day case or one night in hospital. Surgery can be done under ankle block (patient awake) or general anaesthetic. It is best to rest with the foot elevated for the first 2 weeks after surgery. The foot is bandaged and a special sandal supplied by the hospital is worn for 6 weeks. Sensible shoes are to be worn for a further 6 weeks after the bandages are removed. It will take between 3-6 months for the swelling to go down. It will take 12 months before everything completely settles. It is also important to remember that not all bunion operations are entirely successful.
