Bunions Cause And Effect

Overview
Bunions Callous A bunion is a deviation and inflammation of joint where the big toe connects to the 1st metatarsal, also known as the 1st MTP. The capsule of the joint is displaced, thickened and enlarged, and the cartilage of the joint is damaged. There are three degrees of bunions: mild, moderate and severe. It is important to know that bunions are not hereditary, although the tendency to overpronate, which is one of the main causes of bunions, has a hereditary component. Patients complain of pain in the joint and have a big toe that points away from the midline of the body. Often, they are only able to wear very wide shoes.

Causes
The main cause of bunions is a mechanical imbalance in the feet which is usually inherited. The mechanical imbalance is known as overpronation, where the feet roll in towards the arch and big toe. This added weight and stress transfer towards the big toe, causes instability in the structures of this area and a bunion develops.

Symptoms
The most common symptoms associated with this condition are pain on the side of the foot. Shoes will typically aggravate bunions. Stiff leather shoes or shoes with a tapered toe box are the prime offenders. This is why bunion pain is most common in women whose shoes have a pointed toe box. The bunion site will often be slightly swollen and red from the constant rubbing and irritation of a shoe. Occasionally, corns can develop between the 1st and 2nd toe from the pressure the toes rubbing against each other. On rare occasions, the joint itself can be acutely inflamed from the development of a sac of fluid over the bunion called a bursa. This is designed to protect and cushion the bone. However, it can become acutely inflamed, a condition referred to as bursitis.

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
Treatment falls into two broad categories, conservative and surgical. From a conservative standpoint, efforts are directed at correcting faulty foot mechanics with custom molded insoles and relief of symptoms. These include Custom Orthosis to stabilize the abnormal motion of the hind and fore foot. Shoe gear modification: Using shoes with larger toe boxed and more supple materials. Changes in activities. Try to avoid those things which cause symptoms. Anti-inflammatory medication for periodic relief this includes cortisone injections into the joint as well as oral medication. Bunions

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.
