Hallux Abducto Valgus, commonly called bunion, is a bony deformity affecting the angle of the joint at the base of the big toe. Some medical professionals believe that the condition is solely due to ill-fitting footwear, while others believe it is a genetic structural defect that can be exacerbated by shoes. Despite the varying opinions, the reality is that it is probably a combination of both factors. A bunion forms when pressure is applied to the side of the big toe, causing it to become inflamed and painful. The joint then protrudes, effectively making the foot wider. The second toe might then become displaced, which can cause a multitude of other issues like corn and callus development. The bunion joint will have a reduced range of motion and often ends up arthritic. The condition usually develops later in life.
Bunions are a result of complex biomechanical changes that occur in your feet. The type of footwear that you wear does cause bunions. We know that foot bunions occur in about 30% of the population of most Western countries but only 3% in Eastern countries. They are seen most commonly in women and become more common as people get older. Tight-fitting shoes are thought to be the main cause of bunions.. Shoes such as high heels and shoes with tight toe boxes (eg womens fashion shoes and cowboy boots) are particularly damaging to the toes. These shoes have a sloping foot bed and a narrow toe box. The slope causes the front of the foot to bear your weight, which encourages your forefoot to widen. Also, the angle pushes your toes into the narrow toe box, causing the toes to become angled and squeezed together. SymptomsJust because you have a bunion does not mean you have to have pain. There are some people with very severe bunions and no pain and people with mild bunions and a lot of pain. Symptoms for a bunion may include pain on the inside of your foot at the big toe joint. Swelling on the inside of your foot at the big toe joint. Redness on the inside of your foot at the big toe joint. Numbness or burning in the big toe (hallux). Decreased motion at the big toe joint. Painful bursa (fluid-filled sac) on the inside of your foot at the big toe joint. Pain while wearing shoes, especially shoes too narrow or with high heels. Joint pain during activities. Other conditions which may appear with bunions include corns in between the big toe and second toe. Callous formation on the side or bottom of the big toe or big toe joint. Callous under the second toe joint. Pain in the second toe joint.
Bunions are readily apparent - the prominence is visible at the base of the big toe or side of the foot. However, to fully evaluate the condition, the foot and ankle surgeon may take x-rays to determine the degree of the deformity and assess the changes that have occurred. Because bunions are progressive, they don?t go away, and will usually get worse over time. But not all cases are alike - some bunions progress more rapidly than others. Once your surgeon has evaluated your bunion, a treatment plan can be developed that is suited to your needs.
Non Surgical Treatment
A hinged flexible bunion splint, can relieve pain by providing corrective arch support and releasing tension away from the inflamed joint. Change shoes! Avoid flip flops, high-heels and shoes with pointed, narrow toe-boxes. Medicine will not prevent or cure bunions. However, the use of over the counter anti- inflammatory medications can help. Bunion splints, pads and arch supports can help redistribute weight and move pressure away from the big toe.
Procedures are designed and chosen to correct a variety of pathologies that may be associated with the bunion. For instance, procedures may address some combination of removing the abnormal bony enlargement of the first metatarsal, realigning the first metatarsal bone relative to the adjacent metatarsal bone, straightening the great toe relative to the first metatarsal and adjacent toes, realigning the cartilagenous surfaces of the great toe joint, addressing arthritic changes associated with the great toe joint, repositioning the sesamoid bones beneath the first metatarsal bone, shortening, lengthening, raising, or lowering the first metatarsal bone, and correcting any abnormal bowing or misalignment within the great toe. Connecting two parallel long bones side by side by Syndesmosis Procedure. At present there are many different bunion surgeries for different effects. The age, health, lifestyle and activity level of the patient may also play a role in the choice of procedure. Traditional bunion surgery can be performed under local, spinal or general anesthetic. In the case of laser surgery, a narcotic analgesic is typically used. The trend has moved strongly toward using the less invasive local anesthesia over the years. A patient can expect a 6- to 8-week recovery period during which crutches are usually required for aid in mobility. An orthopedic cast is much less common today as newer, more stable procedures and better forms of fixation (stabilizing the bone with screws and other hardware) are used. Hardware may even include absorbable pins that perform their function and are then broken down by the body over the course of months.
