The term ?bunion,? as it is popularly used, describes a variety of deformities involving a painful prominence and swelling at the base of the big toe. Orthopaedists use additional terms to describe the different deformities. The condition in which the big toe deviates from the normal position toward the direction of the second toe is referred to as hallux valgus. Dorsal bunions are a different variety in which the prominence appears on the top of the base of the toe, often the result of an arthritic joint. Causes
Wearing footwear that is too tight or causing the toes to be squeezed together are the most commonly blamed factor for the cause of bunions and hallux valgus and is undoubtedly the main contributing factor. This probably is the reason for the higher prevalence of bunions among women. However, studies of some indigenous populations that never wear footwear, show that they also get bunions but they are very uncommon. As they do get bunions, factors other than footwear must play a role in the cause, even though footwear is the main culprit for providing the pressure that causes the symptoms.
Symptoms
Symptoms often include pain, swelling, and abnormal position of the first toe. The technical term for bunions is ?hallux valgus? (HV). This refers to the first toe or hallux moving away or abducting from the middle of the foot and then twisting in such a way that the inside edge actually touches the ground and the outside edge turns upward. This term describes the deviation of the toe toward the outside part of the foot. If left untreated, bunions can worsen over time and cause considerable difficulty in walking, discomfort, and skin problems such as corns. In some cases, a small bursa (fluid-filled sac) near the joint becomes inflamed. This condition is known as bursitis and can cause additional redness, swelling, and pain. Less frequently, bunions occur at the base of the fifth toe. When this occurs, it is called a ?tailor?s bunion? or bunionette.
Diagnosis
When an x-ray of a bunion is taken, there is usually angulation between the first metatarsal bone and the bones of the big toe. There may also be angulation between the first and second metatarsal bones. These angular irregularities are the essence of most bunions. In general, surgery for bunions aims to correct such angular deformities.
Non Surgical Treatment
The choice of treatment for a bunion lies between non-operative (conservative) and operative treatment. Conservative treatment for a bunion means either wearing wider fitting shoes or shoes with softer leather or using some form of a spacer between the big toe and 2nd toe (or alternatively some form of splint to keep the great toe away from the 2nd toe). The spacers or splintage may apparently straighten the bunion but they make no difference to the width of the foot, and the splaying of the 1st and 2nd metatarsals which occur with a bunion deformity. Therefore this type of treatment will not improve the main pain in a bunion which occurs due to the width of the forefoot. An arch type support orthotic may be useful if a bunion is associated with a flatter foot. If you have a bunion this is however just one other thing to get into a shoe with an already wide foot.
Surgical Treatment
Procedures can range from shaving off excess bone to restructuring and fusing the big toe. For mild conditions, you may simply need the connective tissues holding your big toe to be tightened so they hold the digit in the correct position. More advanced bunions will need more manipulation and involved remedies. Cuts in the bone tissue can help our specialists realign the toe. You may need to have the damaged portion of the joint removed. In severe cases, the joint may be fused to prevent it from moving out of position again. If your bunion created other foot complications, like hammertoes, our specialists may correct those during the procedure as well.
