Acquired Bilateral Hallux Valgus

Overview
A bunion or hallux valgus is a prominence on the inner border of the foot effecting the big toe and at the level of the 1st metatarso-phalangeal (MTP) joint. The bunion prominence which is seen and felt on the inner border of the foot is not due to any growth of bone but is due to the 1st metatarsal bone. With a bunion this has become more prominent than normal because the 1st metatarsal has moved away from its immediate neighbour the 2nd metatarsal. This widens the forefoot thus producing the bunion. An inevitability of the splaying of the foot which occurs with a bunion or hallux valgus is that the great toe itself is then pulled across in the opposite direction (towards the second toe) by the still normally located tendons of the big toe. A bunion or hallux valgus is commonly confused with hallux interphalangeus (where the deformity lies more distally and which tends to be less problematic). Here there is no increase in the space between the metatarsals, and the deformity lies in the shape of the phalynx bone.

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 are an often painful condition that may become even more painful as extra bone and a fluid-filled sac grow at the base of your big toe. Some of the most frequently experienced signs and symptoms associated with bunions, besides pain, include redness in your affected area. Blistering over your bunion. Callus formation around your bunion. Bursitis. Nerve damage (numbness and/or sharp pains) in your involved area. Bunions may also cause pain within and below your first metatarsophalangeal, or MTP, joint. Your bunion may become further dislocated and unstable as it progresses and may overload your adjacent joints.

Diagnosis
Your family doctor or chiropodist /podiatrist can identify a bunion simply by examining your foot. During the exam, your big toe will be moved up and down to determine if your range of motion is limited. You will be examined for signs of redness or swelling and be questioned about your history of pain. A foot x-ray can show an abnormal angle between the big toe and the foot. In some cases, arthritis may also be seen. A X-ray of your foot may help identify the cause of the bunion and rate its severity.

Non Surgical Treatment
Bunions can be treated conservatively (without surgery) using simple measures such as well-fitting shoes, orthoses simple painkillers and padding. Physiotherapy can help improve associated muscle imbalances. Such measures will not correct or even stop the deformity but they can help with symptoms. When non-surgical treatments prove insufficient, surgery can relieve your pain, correct any related foot deformity and help you resume your normal activities.

Surgical Treatment
In severe hallux valgus bunion cases, the first long bone (metatarsal) in the foot dramatically shifts away from the second metatarsal, resulting in looseness and a large deformity. In severe bunion corrections, a surgery known as the Lapidus procedure realigns the first metatarsal into its natural position. Using screws, the surgery holds the bone stable so it does not shift again and reduces the change of the bunion returning to basically none. Surgery may also involve removing the enlarged portion of the bunion region, cutting and realigning the bone, and correcting the position of the tendons and ligaments. By using a special plate with Lapidus procedures, University Foot and Ankle Institute patients are able to put weight on their foot after only 2-3 weeks, rather than the typical 6-8 weeks of no weight.

Prevention
If these exercises cause pain, don't overdo them. Go as far as you can without causing pain that persists. This first exercise should not cause pain, but is great for stimulating blood and lymphatic circulation. Do it as often as you can every day. Only do this exercise after confirming it is OK with your doctor. Lie on your back and lift up your legs above you. Wiggle your toes and feet. Eventually you may be able to rapidly shake your feet for a minute at a time. Use your fingers to pull your big toe into proper alignment. Stretch your big toe and the rest of your toes. Curl them under for 10 seconds, then relax and let them point straight ahead for 10 seconds. Repeat several times. Do this at least once a day, and preferably several times. Flex your toes by pressing them against the floor or a wall until they are bent back. Hold them for 10 seconds, then release. Repeat several times. Grip with your toes. Practice picking up an article of clothing with your toes, dropping it, and then picking it up again. Warm water. Soak your feet for 20 minutes in a bowl of warm water. Try doing the foot exercises while soaking, and also relax and rest your feet. Epsom salts. Add it to your warm foot bath soak.
