Causes Of A Bunion

Overview

A bunion forms when the bursa (a sac of fluid at friction points between the tendons and bone in some areas and between bone and the skin in others) becomes inflamed along the edge of the joint at the base of the big toe. There are two types of bunions. The acute bunion causes the sharper pain. It develops from a bursitis, a sudden outcropping of a fluid-filled sac. An acute bunion can progress into the second type of bunion, the hallux valgus, a chronic but often painless deformity involving permanent rigidity of the bones. Bunions can form in any part of the foot but occur most often at the big toe joint, where the first metatarsal bone abuts the proximal phalanx of the big toe. Women are more likely than men to get bunions because of the misshapen footwear and elevated heels they wear.

Causes
Many problems that occur in the feet are the result of abnormal pressure or rubbing. One way of understanding what happens in the foot due to abnormal pressure is to view the foot simply. Our simple model of a foot is made up of hard bone covered by soft tissue that we then put a shoe on top of. Most of the symptoms that develop over time are because the skin and soft tissue are caught between the hard bone on the inside and the hard shoe on the outside. Any prominence, or bump, in the bone will make the situation even worse over the bump. Skin responds to constant rubbing and pressure by forming a callus. The soft tissues underneath the skin respond to the constant pressure and rubbing by growing thicker. Both the thick callus and the thick soft tissues under the callus are irritated and painful. The answer to decreasing the pain is to remove the pressure. The pressure can be reduced from the outside by changing the pressure from the shoes. The pressure can be reduced from the inside by surgically removing any bony prominence.
SymptomsThe pain from a bunion is felt around the MTP joint of the big toe. People with bunions often complain of pain when they when they stand or walk for long periods of time. High heeled making shoes or shoes with a small toe area can make bunions feel and look worse. As a result of the deformity the big toe can lose some of its range of motion or become stiff. Sometimes both feet are affected.

Diagnosis
Your doctor is very likely to be able to diagnose your bunion simply by examining your foot. Even before that, he or she will probably ask about your family and personal medical history and evaluate the types of shoes you wear. You'll be asked about your symptoms, when they started and when they occur. You may also be asked to flex your toe so that your doctor can get an idea of your range of motion. He or she may order x-rays in order to determine the extent of your deformity.

Non Surgical Treatment
The treatment method your doctor chooses for you will be based on the severity of the bunion. Treatment can be simple and non-surgical or it can be complex, surgical, and costly. A bunion is permanent unless surgery is performed to remove it, but self-care can help to improve your symptoms. If you suspect that a bunion is developing, you should seek medical attention immediately. Here are the most common conservative treatment options. Changing your shoes. Adding custom orthotics to your shoes. Medication such as Tylenol for pain relief. Padding and taping to put your foot in its normal position. Applying ice or cold compresses to reduce swelling and pain. Keeping pressure off your affected toe, especially if there is swelling, redness, and pain. Before bed, separate the affected toe from the others with a foam-rubber pad and leave it there while you sleep.


Surgical Treatment
Surgery might be recommended if non-surgical treatments fail to provide relief, and you are having trouble walking or are in extreme pain. Surgery can be used to return the big toe to its correct anatomical position. During surgery, bones, ligaments, tendons, and nerves are put back into correct order, and the bump is removed. Many bunion correction procedures can be done on a same-day basis. The type of procedure will depend on your physical health, the extent of the foot deformity, your age, and your activity level. The recovery time will depend on which procedure or procedures are performed. Surgery may be recommended to correct a tailor?s bunion, but is unlikely to be recommended for an adolescent bunion.
