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.
Many problems that occur in the feet are the result of abnormal pressure or rubbing. One way of understanding what happens in the foot due to abnormal pressure is to view the foot simply. Our simple model of a foot is made up of hard bone covered by soft tissue that we then put a shoe on top of. Most of the symptoms that develop over time are because the skin and soft tissue are caught between the hard bone on the inside and the hard shoe on the outside. Any prominence, or bump, in the bone will make the situation even worse over the bump. Skin responds to constant rubbing and pressure by forming a callus. The soft tissues underneath the skin respond to the constant pressure and rubbing by growing thicker. Both the thick callus and the thick soft tissues under the callus are irritated and painful. The answer to decreasing the pain is to remove the pressure. The pressure can be reduced from the outside by changing the pressure from the shoes. The pressure can be reduced from the inside by surgically removing any bony prominence.
The most obvious symptoms of a bunion are. Pain in the area of the MTP joint, the joint where your big toe connects to your foot. Bending of the big toe in towards the other toes. An enlarged bump of bone or tissue at the MTP joint. Each symptom can range in degree from small to severe. Sometimes the pain can be sufficient to make it difficult to walk in normal shoes. Other symptoms may include. Swelling and inflammation of the skin around the MTP joint. Thickening of the skin in the area of the joint. Restricted motion in your big toe. Pressure from the inward bending of your big toe can affect your other toes, leading to corns on your smaller toes. Ingrown toenails on the smaller toes. Development of hammertoes in the other toes. Calluses on the bottom of your foot. If you have any of these symptoms, especially pain, displacement of your big toe or development of a bulge, you should consider consulting your physician. Even if you're not significantly bothered by some of these symptoms, bunions tend to continue getting bigger and more serious over time and should be taken care of before they do so.
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
Wearing good footwear does not cure the deformity but may ease symptoms of pain and discomfort. Ideally, get footwear advice from a person qualified to diagnose and treat foot disorders (podiatrist - previously called a chiropodist). Advice may include wear shoes, trainers or slippers that fit well and are roomy. Don't wear high-heeled, pointed or tight shoes. You might find that shoes with laces or straps are best, as they can be adjusted to the width of your foot. Padding over the bunion may help, as may ice packs. Devices which help to straighten the toe (orthoses) are still occasionally recommended, although trials investigating their use have not found them much better than no treatment at all. Painkillers such as paracetamol or ibuprofen may ease any pain. If the bunion (hallux valgus) develops as part of an arthritis then other medication may be advised. A course of antibiotics may be needed if the skin and tissues over the deformity become infected.
Bunion surgery is most often performed as an out-patient, this means you go home that same day. It will likely be done at a hospital or out-patient (ambulatory) surgery center. The anesthetic choices with bunion surgery are local with sedation, spinal or general anesthesia. You wouldn?t expect that a small bunion would be treated exactly the same as a large one. Over the years, surgeons have developed dozens of methods to surgically correct bunions. But don?t worry because only a handful of methods are used today. With most bunion surgeries today, the procedure involves a combination of soft-tissue rebalancing of ligaments and tendons as well as bone work to re-align the foot structure. You may have heard people say they had their ?bunion shaved.? In most cases, the surgery often involves much more than simply shaving the bunion. The shaving part of the procedure is called an ?exostectomy? and often performed in conjunction with other methods.
To minimize the chance of developing bunions, never force your feet into shoes that don?t fit. Choose a shoe that conforms to the shape of your foot. Opt for shoes with wider insteps, broad toes, and soft soles. Shoes that are short, tight, or sharply pointed should be avoided.
