A bunion is enlargement of bone or tissue that develops at the joint that connects your big toe to your foot. The bones, muscles, ligaments and tendons of your feet normally are well-balanced to distribute your body's weight while standing, walking and running. When the joint, called the metatarsophalangeal joint, or MTP joint, experiences abnormal, prolonged stress in terms of weight distribution or squeezing of the toes within the shoe, the result can be the deformity called a bunion. Generally, a bunion develops when, as a response to prolonged stress, your big toe begins bending toward your foot's smaller toes and puts pressure on your MTP joint, forcing it to bulge outward (the term "bunion" comes from the Latin word for "enlargement"). There is no "standard" bunion, however, but rather a complex range of joint, bone and tendon abnormalities that can cause variation in each bunion's make-up.
Bunions tend to run in families, but that does not mean that if you have a bunion, your children will inevitably have one too. The connection may be that bunions are a bit commoner in people with unusually flexible joints, and this can be hereditary. They are also commoner in women than in men. Bunions do occur in cultures in which shoes are not worn, but much less commonly. Shoes which squeeze the big toe or do not fit properly, or have an excessively high heel, may worsen the deformity, particularly in people who are at higher risk anyway.
The most common symptoms associated with this condition are pain on the side of the foot. Shoes will typically aggravate bunions. Stiff leather shoes or shoes with a tapered toe box are the prime offenders. This is why bunion pain is most common in women whose shoes have a pointed toe box. The bunion site will often be slightly swollen and red from the constant rubbing and irritation of a shoe. Occasionally, corns can develop between the 1st and 2nd toe from the pressure the toes rubbing against each other. On rare occasions, the joint itself can be acutely inflamed from the development of a sac of fluid over the bunion called a bursa. This is designed to protect and cushion the bone. However, it can become acutely inflamed, a condition referred to as bursitis.
Looking at the problem area on the foot is the best way to discover a bunion. If it has the shape characteristic of a bunion, this is the first hint of a problem. The doctor may also look at the shape of your leg, ankle, and foot while you are standing, and check the range of motion of your toe and joints by asking you to move your toes in different directions A closer examination with weight-bearing X-rays helps your doctor examine the actual bone structure at the joint and see how severe the problem is. A doctor may ask about the types of shoes you wear, sports or activities (e.g., ballet) you participate in, and whether or not you have had a recent injury. This information will help determine your treatment.
Non Surgical Treatment
Initial treatment of bunions may include wearing comfortable, well-fitting footwear (particularly shoes that conform to the shape of the foot and do not cause pressure areas) or the use of splints and orthotics (special shoe inserts shaped to your feet) to reposition the big toe. For bunions caused by arthritis, medications may help reduce pain and swelling. If nonsurgical treatment fails, your doctor may suggest surgery, which resolves the problem in nearly all persons. The goal of surgery is to relieve pain and correct as much deformity as possible. The surgery is not cosmetic and is not meant to improve the appearance of the foot. Other related procedures that may be used to help diagnose foot disorders include X-rays of the bone and foot.
If conservative treatment doesn't provide relief from your symptoms, you may need surgery. The goal of bunion surgery is to relieve discomfort by returning your toe to the correct position. There are a number of surgical procedures for bunions, and no one technique is best for every problem. Surgical procedures for bunions might involve removing the swollen tissue from around your big toe joint. Straightening your big toe by removing part of the bone. Realigning the long bone between the back part of your foot and your big toe, to straighten out the abnormal angle in your big toe joint. Joining the bones of your affected joint permanently. It's possible you may be able to walk on your foot immediately after a bunion procedure. However, full recovery can take weeks to months. To prevent a recurrence, you'll need to wear proper shoes after recovery. It's unlikely that you'll be able to wear narrower shoes after surgery. Surgery isn't recommended unless a bunion causes you frequent pain or interferes with your daily activities. Talk to your doctor about what you can expect after bunion surgery.
Wear insoles and well-fitting shoes to help slow down the progression of bunions and alleviate discomfort. Cushioning can also help alleviate discomfort. Consider wearing shoes with a wide toe box so they don't crowd your toes. Children can also develop bunions and should wear properly fitting shoes as their feet are still developing.
