Overview
A bunion or hallux abducto valgus occurs when your big toe points toward your second toe. The big toe will touch the second or causes the second toe to overlap the big toe. This causes a boney bump to appear on the outside edge of your big toe. Bunions are more common in women and can sometimes run in families. Hallux abducto valgus can develop as a result of an inherited structural defect or stress on your foot or due to a medical condition such as arthritis. If there is an underlying structural defect in your foot this can lead to compensations causing stresses and pressures to be applied unevenly on the joints and tendons in your feet. This imbalance in pressure and stress makes your big toe joint unstable. Over time this causes the medial side of the 1st metatarsal head to develop excess bone that protrudes out beyond the normal shape of your foot. The size of the bunion can get larger over time which causes further crowding your other toes and causing pain. Pain from a bunion can be severe enough to keep you from walking comfortably in normal shoes. The condition may become painful as the bump gets worse, and extra bone and a fluid-filled sac (bursa) grow at the base of the big toe. By pushing your big toe inward, a bunion can squeeze your other toes into abnormal positions. This crowding can cause the four smaller toes to become bent or a claw-like in shape. These bent toes are known as hammertoes. Smaller bunions called ?bunionettes? can also develop on the joint of your 5th toe.
Causes
There is no single cause of hallux valgus. It most commonly runs in families but may skip generations. High heel, pointed toe shoes are not the primary cause of the hallux valgus but they do cause it to be painful. Pressure from shoes may cause bunions, corns and calluses to develop where there is hallux valgus deformity.
Symptoms
Symptoms include pain in and around the ball of the big toe, usually from the bone rubbing too much against the shoe. You may be unable to wear certain types of shoes due to the shape of the forefoot. The big toe appears to be bent inwards towards and in come cases over the inside toe.
Diagnosis
Your doctor will ask questions about your past health and carefully examine your toe and joint. Some of the questions might be: When did the bunions start? What activities or shoes make your bunions worse? Do any other joints hurt? The doctor will examine your toe and joint and check their range of motion. This is done while you are sitting and while you are standing so that the doctor can see the toe and joint at rest and while bearing weight. X-rays are often used to check for bone problems or to rule out other causes of pain and swelling. Other tests, such as blood tests or arthrocentesis (removal of fluid from a joint for testing), are sometimes done to check for other problems that can cause joint pain and swelling. These problems might include gout , rheumatoid arthritis , or joint infection.
Non Surgical Treatment
Bunions are progressive problems, meaning they tend to get worse over time. Sometimes severe-looking bunions don't hurt much, and sometimes relatively modest-looking bunions hurt a great deal. Thus, treatment varies depending upon a patient's symptoms. You can often improve the discomfort of bump pain by a change to more proper shoes. Alternatively, alterations to existing shoes may improve pain associated with bunions. Accommodative padding, shields and various over-the-counter and custom-made orthopaedic appliances can also alleviate bunion pain. Anti-inflammatory medications, steroid injections, physiotherapy, massage, stretching, acupuncture and other conservative treatment options may be recommended by your podiatric physician to calm down an acutely painful bunion. Long term, orthoses (orthotics) can address many of the mechanical causes of a bunion. Thus, while orthoses don't actually correct a bunion deformity, if properly designed and made, they can slow the progression of bunions. They can also be made to redistribute weight away from pain in the ball of the foot, which often accompanies bunion development. Padding, latex moulds and other accommodative devices may also be effective. While they don't correct the misalignment in the bones, they may alleviate pain. Often, though, when conservative measures fail to alleviate pain associated with the bunion, when you start to limit the types of activities you perform, when it's difficult to find comfortable shoes, and when arthritis changes how you walk, surgery may be the best alternative.
Surgical Treatment
Surgery may be recommended for some bunions, but only when symptoms are severe enough to warrant such intervention. Surgery for a bunion, called a bunionectomy, is done in hospital usually under general anaesthesia. The surgeon can often realign the bone behind the big toe by cutting the ligaments at the joint. For a severe bunion, you may need to have the bone cut in a technique called an osteotomy. Wires or screws may be inserted to keep the bones in line, and excess bone may be shaved off or removed. Potential complications of surgery include recurrence of the bunion, inadequate correction, overcorrection (the toe now points inwards), continued pain, and limited movement of the big toe.
