The common bunion is a localized area of enlargement of the inner portion of the joint at the base of the big toe. The enlargement actually represents additional bone formation, often in combination with a misalignment of the big toe. The misalignment causes the big toe to move outward (medically termed hallux valgus deformity). The normal position of the big toe (straight forward) becomes outward directed toward the smaller toes. The enlarged joint at the base of the big toe (the first metatarsophalangeal joint, or MTP joint) can become inflamed with redness, tenderness, and pain. A small fluid-filled sac (bursa) adjacent to the joint can also become inflamed (bursitis), leading to additional swelling, redness, and pain. A less common bunion is located at the joint at the base of the smallest (fifth) toe. This bunion is sometimes referred to as a tailor's bunion.
Shoes with narrow toes can trigger a bunion, but they?re not the underlying cause. Bunions run in families, because foot type (shape and structure) is hereditary, and some types are more prone to bunions than others. Low arches, flat feet, and loose joints and tendons all increase the risk. The shape of the metatarsal head (the top of the first metatarsal bone) also makes a difference: if it?s too round, the joint is less stable and more likely to deform when squeezed into shoes with narrow toes.
SymptomsSigns and symptoms of a bunion include the base of the big toe is swollen and sticks out. The big toe is often bent towards the other toes, and sometimes the second toe is pushed to overlap the third toe. Skin around the big toe joint is red and sore. Thickened skin at the base of the big toe. Pain in the big toe or foot. Wearing shoes is painful. Pain or difficulty when walking.
X-rays are the best way to determine the amount of deformity of the MTP joint. Blood work may be required to rule out other diseases that may be associated with bunions such as rheumatoid arthritis. Other tests such as bone scans or MRI's are not usually required.
Non Surgical Treatment
Podiatrists will treat bunions conservatively, using paddings and orthotics, which are devices that are made to protect the joint or deviate pressure away from it. Sometimes bunions will develop overlying callus or corns. These can be removed by a podiatrist, but if the area is irritated again by wearing ill-fitting footwear, the corn will grow back. Most people with this condition have flat feet, so arch supports are often recommended.
Surgery isn't recommended unless a bunion causes you frequent pain. A bunionectomy, like other types of surgery, is not without risk. Additionally, you may still have pain or you could develop a new bunion in your big toe joint after surgery. Consider trying conservative treatment before having a bunionectomy.If you have an underlying mechanical fault,surgery will only correct the aesthetical nature of your bunion for a short period.So therefore surgery is not recommended.
