A bunion is a bony bump on the joint at the base of your big toe. The bony growth on the joint sometimes causes your big toe to Bunion Surgery at Nuffield Health Hospitalsturn in towards your second toe. Symptoms include pain, swelling of your big toe and, as the bunion sticks out, it can often rub on the inside of your shoe. The cause is not always known, there may be a deformity of the joint, called hallux valgus (hallux means big toe, valgus means bent outwards). Or it can be as simple as ill fitting footwear not allowing enough width to fit the toes in their natural position. Sometimes bunions are associated with arthritis in the joint at the base of your big toe. Left untreated bunions can continue to grow and become more painful. Causes
Bunions are most often caused by an inherited faulty mechanical structure of the foot. This faulty structure causes the drifting of the great toe and the bone to become prominent on the side of the foot. The skin then gets pinches by this bony prominence and the shoe. Therefore in most cases bunions are not caused by tight shoes but are made more painful by tight shoes. End stage bunions may become painful both in and out of shoes.
Symptoms
Many people with bunions suffer from discomfort and pain from the constant irritation, rubbing, and friction of the enlargement against shoes. The skin over the toe becomes red and tender. Because this joint flexes with every step, the bigger the bunion gets, the more it hurts to walk. Over time, bursitis or arthritis may set in, the skin on the bottom of the foot may become thicker, and everyday walking may become difficult-all contributing to chronic bunion pain.
Diagnosis
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
Wide toe box, bunion pads, orthotics, or a combination. Mild discomfort may lessen by wearing a shoe with a wide toe box or with stretchable material. If not, bunion pads purchased in most pharmacies can shield the painful area. Orthotics can also be prescribed to redistribute and relieve pressure from the affected articulation. If conservative therapy fails, surgery aimed at correcting abnormal bony alignments and restoring joint mobility should be considered. If the patient is unwilling to wear large, wider shoes to accommodate the bunion because they are unattractive, surgery can be considered; however, patients should be told that orthotic devices should be worn after surgery to reduce the risk of recurrence. For bursitis, bursal aspiration and injection of a corticosteroid are indicated. For osteoarthritic synovitis, oral NSAIDs or an intra-articular injection of a corticosteroid/anesthetic solution reduces symptoms. For hallux limitus or hallux rigidus, treatment aims to preserve joint mobility by using passive stretching exercises, which occasionally require injection of a local anesthetic to relieve muscle spasm. Sometimes surgical release of contractures is necessary.
Surgical Treatment
If the bunion symptoms does not respond to the conservative measures or if the bunion has progressed past a threshold where these measures are not effective, bunion surgery may be necessary to correct alignment and remove the bunion. A large range of types of surgical procedures for bunions are available and the choice will depend on things like what bone or bones are involved, the angular relationship between the different bones, the amount of damage to the joint and the presence of deformities other than the bunion.
Prevention
The best way to reduce your chances of developing a bunion is to wear shoes that fit properly. Any shoe that is too tight or too high will force your toes together and may cause the condition to develop. Shoes need to be wide enough, so they aren't rubbing against the joint, and preferably made of leather. Avoid shoes with a lot elaborate stitching at the front, as this can also cause irritation. Heels should be no more than three to four inches and you should only wear them occasionally. Court shoes should seldomly be worn, as they do not give the foot any support. Be honest with yourself, you know if your shoes aren't fitting you comfortably. Do something about it, or you will suffer for your vanity.
