Why Do I Have Hallux Valgus

Overview

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. The word bunion refers specifically to the prominence made of bone and at times an inflamed bursa. This bursa develops on the first metatarsal head at the base of the big toe because of this bony prominence. Although a bunion may develop without hallux valgus, for the purposes of this discussion, the term bunion will include both. Dorsal bunions, are a separate entity, in which the prominence appears on the top of the base of the toe-often the result of an arthritic joint.

Causes
Abnormality in foot function, particularly a pronated foot. This is probably the most important and common causative factor. Family history of bunions. Narrow toed dress shoes and high heels may contribute to the formation of a bunion. Rheumatoid and Psoriatic arthritis. Genetic and neuromuscular disease (eg. Down's,Ehler-Danlos and Marfan's syndromes) resulting in muscle imbalance. Limb length inequality can cause a bunion on the longer limb. Generalized laxity of the ligaments. Trauma to or surgery on the soft tissue structures around the great toe (first metatarsal-phalangeal) joint.
SymptomsThe most common symptoms of foot bunions are toe Position, the toe points inwards towards the other toes in the foot into the hallux adbucto valgus position and may even cross over the next toe. Bony Lump, swelling on the outer side of the base of the toe which protrudes outwards. Redness, over the bony lump where it becomes inflamed. Hard Skin, over the bony lump known as a callus. Pain, it is often painful around the big toe, made worse by pressure on the toe and weight bearing activities. Change in Foot Shape, Your whole foot may gradually change shape for example getting wider. Stiffness, the big toe often becomes stiff and may develop arthritis. Foot bunions are more common with increasing age. They develop gradually overtime from repeated force through the big toe and left untreated, become more pronounced with worsening symptoms.

Diagnosis
Diagnosis begins with a careful history and physical examination by your doctor. This will usually include a discussion about shoe wear and the importance of shoes in the development and treatment of the condition. X-rays will probably be suggested. This allows your doctor to measure several important angles made by the bones of the feet to help determine the appropriate treatment.

Non Surgical Treatment
Padding with a number of different materials (eg felt) to reduce pressure on the painful prominence of the bunion. Physical therapy can be used to help with the symptoms and improve the range of motion (this is particularly helpful if the pain is coming from inside the joint, rather than from shoe pressure). Manipulation of the joint can be used to help with this (manipulation will never correct the alignment of the joint). Any corns and calluses that are causing symptoms should be treated. The correct fitting of footwear is essential for anyone who is serious about doing something about their bunions and hallux valgus. It may be possible to have your shoes stretched over the area of the bunion to also relieve pressure. Foot orthotics may be useful in helping with the instability about the joint. They may be more helpful if there are other symptoms in the foot as well, as their use in "treating" bunions is controversial. They may play a role in slowing progression and in the prevention of bunions developing again after surgical correction. Exercises can be important in maintaining the mobility of the joint in those with bunions, this is especially important for the arthritic type pains that may be originating from inside the joint and for the prevention of these painful symptoms in the future.


Surgical Treatment
If conservative treatment doesn't provide relief, you may need surgery. A number of surgical procedures are performed for bunions, and no particular surgery is best for every problem. Knowing what caused your bunion is essential for choosing the best procedure to ensure correction without recurrence. Most surgical procedures include rmoving the swollen tissue from around your big toe joint Straightening your big toe by removing part of the bone Permanently joining the bones of your affected joint You may be able to walk on your foot immediately after some bunion procedures. With other procedures, it may be a few weeks or longer. To prevent a recurrence, you'll need to wear proper shoes after recovery.
