Overview
The term "hallux valgus" or "hallux abducto-valgus" are the most commonly used medical terms associated with a bunion anomaly, where "hallux" refers to the great toe, "valgus" refers to the abnormal angulation of the great toe commonly associated with bunion anomalies, and "abductus/-o" refers to the abnormal drifting or inward leaning of the great toe towards the second toe, which is also commonly associated with bunions. It is important to state that "hallux abducto" refers to the motion the great toe moves away from the body's midline. Deformities of the lower extremity are usually named in accordance to the body's midline, or the line bisecting the body longitudinally into two halves. In more severe cases, the hallux continuing in the abductus fashion eventually either overlaps or underlaps subsequent lesser (small) toes especially the second (adjacent toe).
Causes
Bunions are more common in women than men. The problem can run in families. People born with abnormal bones in their feet are more likely to form a bunion. Wearing narrow-toed, high-heeled shoes may lead to the development of a bunion. The condition may become painful as the bump gets worse. Extra bone and a fluid-filled sac grow at the base of the big toe.
Symptoms
Bunions may or may not cause symptoms. A frequent symptom is foot pain in the involved area when walking or wearing shoes that is relieved by resting. A bunion causes enlargement of the base of the big toe and is usually associated with positioning of the big toe toward the smaller toes. This leads to intermittent or chronic pain at the base of the big toe. Bunions that cause marked pain are often associated with swelling of the soft tissues, redness, and local tenderness. It is important to note that, in post-pubertal men and post-menopausal women, pain at the base of the big toe can be caused by gout and gouty arthritis that is similar to the pain caused by bunions.
Diagnosis
Before examining your foot, the doctor will ask you about the types of shoes you wear and how often you wear them. He or she also will ask if anyone else in your family has had bunions or if you have had any previous injury to the foot. In most cases, your doctor can diagnose a bunion just by examining your foot. During this exam, you will be asked to move your big toe up and down to see if you can move it as much as you should be able to. The doctor also will look for signs of redness and swelling and ask if the area is painful. Your doctor may want to order X-rays of the foot to check for other causes of pain, to determine whether there is significant arthritis and to see if the bones are aligned properly.
Non Surgical Treatment
Bunion pain can be successfully managed in the vast majority of cases by switching to shoes that fit properly and don't compress the toes. Your orthopaedic surgeon can give you more information about proper shoe fit and the types of shoes that would be best for you. Follow these general points of shoe fit. Do not select shoes by the size marked inside the shoe. Sizes vary among shoe brands and styles. Judge the shoe by how it fits on your foot. Select a shoe that conforms as nearly as possible to the shape of your foot. Have your feet measured regularly. The size of your feet change as you grow older. Have both feet measured. Most people have one foot larger than the other. Fit to the largest foot. Fit at the end of the day when your feet are the largest. Stand during the fitting process and check that there is adequate space (3/8" to 1/2") for your longest toe at the end of each shoe. Make sure the ball of your foot fits well into the widest part (ball pocket) of the shoe. Do not purchase shoes that feel too tight, expecting them to "stretch" to fit. Your heel should fit comfortably in the shoe with a minimum amount of slippage. Walk in the shoe to make sure it fits and feels right. (Fashionable shoes can be comfortable.) Some shoes can be modified by stretching the areas that put pressure on your toes. Splints to reposition the big toe and orthotics (special shoe inserts shaped to your feet) also may relieve pain. For bunions caused by arthritis, medications can be prescribed to reduce pain and swelling.
Surgical Treatment
As you explore bunion surgery, be aware that so-called "simple" or "minimal" surgical procedures are often inadequate "quick fixes" that can do more harm than good. And beware of unrealistic claims that surgery can give you a "perfect" foot. The goal of surgery is to relieve as much pain, and correct as much deformity as is realistically possible. It is not meant to be cosmetic. There are several techniques available, often as daycare (no in-patient stay), using ankle block local anaesthetic alone or combined with sedation or full general anaesthesia. Most of the recovery occurs over 6-8 weeks, but full recovery is often longer and can include persistent swelling and stiffness. The surgeon may take one or more of the following steps in order to bring the big toe back to the correct position: (a) shift the soft tissue (ligaments and tendons) around the joint and reset the metatarsal bone (osteotomy), remove the bony bump and other excess bone or (b) remove the joint and connect (fuse) the bones on the two side of the joint (fusion). These are just a few examples of the many different procedures available and your treating surgeon can help you decide the best option for you.
