Bunions are the most common deformity that affects the big toe. A bunion is characterized by angling of the big toe towards the lesser toes, and a painful bump over the inside part of the base of the big toe. This prominence (an area called the medial eminence) is caused by angling inwards of the metatarsal bone, and is not an actual growth of bone.
Bunions are caused by pressure on the inside of the forefoot which causes the 1st metatarsal bone in the foot to migrating outwards. Biomechanical factors can contribute to the development of bunions for example if you over pronate where the foot rolls in or flattens excessively which causes the inside of the foot to rub against the shoe. Wearing high heeled shoes regularly also increases the risk of developing the condition . The pressure on the forefoot is increased considerably as the heel is raised up. Age is also a factor as the ligaments lose strength as you get older.
Since the pain from a bunion is always aggravated by shoe wear, the symptoms will often depend on the type and size of shoes worn. The perception of pain or discomfort that people experience is quite varied. There are some individuals who have small bunions that are very uncomfortable. This limits their ability to wear shoes comfortably. On the other hand, some individuals may have quite significant deformities that are annoying but do not limit their activities in anyway.
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
In the early stages of the formation of a bunion, soaking feet in warm water can provide temporary relief. The best way to alleviate the pain associated with bunions is to wear properly fitting shoes. Shoes designed with a high, wide toe box (toe area) are recommended for people suffering from forefoot disorders, such as bunions. Shoes with rocker soles will unload pressure to the bunion area. Orthotics are also recommended for this condition to provide extra comfort, support, and protection. Other conservative treatments include using forefoot products designed to accommodate and relieve bunions such as bunion shields, bunion night splints, and bunion bandages. These conservative treatments can limit the progression of the bunion formation, relieve pain and provide a healthy environment for the foot.
When deciding whether to have bunion surgery, there are several things to consider including your age, in children, bunion surgery is often delayed because of the risk of the bunion returning, your medical history and general health, problems with wound healing and infections are more likely in certain conditions such as diabetes, you?re also more likely to develop problems if your bunion is caused by a condition such as rheumatoid arthritis, your occupation and lifestyle, bunion surgery can make your toes less flexible, and you may be unable to return to the same level of physical activity, your expectations of surgery, bunion surgery has about an 85% success rate, but there's no guarantee that your foot will be perfectly straight or pain-free; the success of surgery depends on the type of procedure, the experience of the surgeon and your ability to rest after the operation, the severity of your symptoms, surgery will usually only be recommended if your bunions are causing considerable pain and non-surgical treatments haven't been unsuccessful (because of the associated risks and complications).
