What Is A A Bunionectomy?

カテゴリ:カテゴリ未分類

Overview

A bunion is a very common foot deformity that develops over the first metatarsal phalageal joint of the big toe of the foot. The joint that joins the big toe to the foot is called the first MTP joint. When it becomes prominent and the big toe starts to become crooked this is known as a bunion. The term referring to deformity of the big toe as it becomes crooked is called Hallux Valgus. It is the bump itself that is known as the bunion. When it gets red and swollen over the bunion because it gets sore this is usually due to an inflamed soft tissue over the underlying bone.

Causes
Foot problems typically develop in early adulthood and get worse as the foot spreads with aging. For many people, bunions run in the family. They may be just one of several problems due to weak or poor foot structure. Bunions sometimes develop with arthritis. In people with leg length discrepancies, bunions usually form in the longer leg. Women are especially prone to developing bunions. Years of wearing tight, poorly fitting shoes especially high-heeled, pointed shoes can bring on bunions. Such shoes gradually push the foot bones into an unnatural shape.
SymptomsSymptoms include redness, swelling and pain which may be present along the inside margin of the foot. The patients feet may become too wide to fit into their normal size shoes and moderate to severe discomfort may occur when the patient is wearing tight shoes. A "hammer toe" may occur at the 2nd toe. This is when the toe contracts and presses on the shoe. Subsequently, this may cause a corn on top of the 2nd toe.

Diagnosis
A doctor can very often diagnose a bunion by looking at it. A foot x-ray can show an abnormal angle between the big toe and the foot. In some cases, arthritis may also be seen.

Non Surgical Treatment
Bunions may be treated conservatively with changes in shoe gear, different orthotics (accommodative padding and shielding), rest, ice and medications. These sorts of treatments address symptoms more than they correct the actual deformity. Surgery, by an orthopedic surgeon or a podiatric surgeon, may be necessary if discomfort is severe enough or when correction of the deformity is desired. Orthotics are splints or regulators while conservative measures include various footwear like gelled toe spacers, bunion toes separators, bunion regulators, bunion splints and bunion cushions. There are a variety of available orthotics (or orthoses) including over-the-counter or off-the-shelf commercial products and as necessary, custom-molded orthotics that are generally prescribed medical devices.


Surgical Treatment
The main goal of surgery is to realign the big toe joint in order to relieve symptoms, correct deformity and restore function. Surgery to remove a bunion is known as a bunionectomy. There are many variations of this operation and the type of surgery performed will vary depending on factors such as the degree of deformity, the strength of the bones, the person's age and the surgeon?s preferred approach. Most surgery involves the removal of the bony outgrowth (exostosis) and the realignment of the bones of the joint. Soft tissue structures such as the ligaments and tendons may be repositioned and the bursa may be removed. The insertion of screws and pins may be required to stabilise the bones in their new, realigned position.
