Overview
People think of a bunion as being as a bump on the side of the foot near the big toe. However, bunions go deeper than what we can see. Although the skin might be red, a bunion actually reflects a change in the anatomy of the foot. Bunions happen over time. What begins as the big toe pointing toward the second toe ends up as changes in the actual alignment of the bones in the foot. There is also a condition called tailor?s bunion or bunionette. This type of bump differs from a bunion in terms of the location. A tailor?s bunion is found near the base of the little toe on the outside of the foot.
Causes
The main cause of bunions is a mechanical imbalance in the feet which is usually inherited. The mechanical imbalance is known as overpronation, where the feet roll in towards the arch and big toe. This added weight and stress transfer towards the big toe, causes instability in the structures of this area and a bunion develops.
Symptoms
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.
Diagnosis
People with bunions may be concerned about the changing appearance of their feet, but it is usually the pain caused by the condition that leads them to consult their doctor. The doctor will evaluate any symptoms experienced and examine the affected foot for joint enlargement, tissue swelling and/or tenderness. They will also assess any risk factors for the condition and will ask about family history. An x-ray of the foot is usually recommended so that the alignment of big toe joint can be assessed. This would also allow any other conditions that may be affecting the joint, such as arthritis, to be seen.
Non Surgical Treatment
A range of treatments is available for bunions, including painkillers, modifying footwear, orthotics, such as insoles, bunion pads and toe spacers. Surgery may be considered if a person's symptoms are severe and do not respond to non-surgical treatment. The type of surgery used will depend on the level of deformity, the severity of any other associated symptoms, the patient's age and any other associated medical conditions. Bunion surgery is usually effective, with up to 85% of cases resulting in improvement to symptoms. However, the deformity can sometimes return after bunion surgery.
Surgical Treatment
There are dozens and dozens of types of surgery designed to address bunion deformities, and each have different indications. But in short, some procedures simply address an enlarged bump. Some simply address a crooked big toe. But in order to slow the return of the bunion deformity, most procedures aim to realign the big toe with the bone behind it, the "first metatarsal." This would also realign the joint surfaces between those two bones. But even if the surgery is designed to realign the big toe, there are still many choices to consider. Some procedures are meant for a short first metatarsal and others for a long first metatarsal. Some are best when the foot is very unstable, others are based on the severity of the arthritis present. In fact, there are many, many factors to consider when designing a procedure to address a particular patient's foot, to the extent that what's involved in a bunion surgery not only varies from patient to patient--the procedures often vary even from a patient's right foot to the left foot.
