When the big toe is misaligned, it creates an unnatural bump on the inside of the forefoot (see image below). In addition to being unsightly, the lump or bunion can cause pain and make buying shoes difficult. Some people are born predisposed to bunions. But most people acquire them over time from ill-fitting footwear that squeezes the big toe inward toward the other toes. About four out of five bunion pain patients are female, a near perfect fit for the bad shoe theory. The good news, Bunions can be corrected, often with better-fitting shoes and custom orthotics. There are also some cases that cause severe bunion pain and do not respond to conservative treatment. For those patients, bunion surgery called bunionectomy may be necessary.
The most important causative factor is poor fitting footwear. This accounts for an higher incidence among women than men. Family history of bunions. Abnormal foot function, excessive pronation. Poor foot mechanics, such as excessive pronation (rolling inwards of the foot), causes a medial force which exerts pressure and can lead to the formation of bunions. Rheumatoid or osteoarthritis. Genetic and neuromuscular diseases, which can result in a muscular imbalance such as Down's syndrome. If one leg is longer then the other, the longer leg is more inclined to develop a bunion. If the ligaments in the feet are very weak. In some cases, bunions can occur due to trauma or injury to the feet.
The main sign of a bunion is the big toe pointing towards the other toes on the same foot, which may force the foot bone attached to it (the first metatarsal) to stick outwards. Other symptoms may include a swollen, bony bump on the outside edge of your foot, pain and swelling over your big toe joint that's made worse by pressure from wearing shoes, hard, callused and red skin caused by your big toe and second toe overlapping, sore skin over the top of the bunion, changes to the shape of your foot, making it difficult to find shoes that fit. These symptoms can sometimes get worse if the bunion is left untreated, so it's best to see a GP. They'll ask you about your symptoms and examine your foot. In some cases, an X-ray may be recommended to assess the severity of your bunion. Anyone can develop a bunion, but they're more common in women than men. This may be because of the style of footwear that women wear.
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.
Surgery may be considered if your symptoms are severe and don't respond to non-surgical treatments. The type of surgery will depend on the level of deformity, the severity of your symptoms, your age, and any other associated medical conditions.
