Overview
A bunion is an unnatural, bony hump that forms at the base of the big toe where it attaches to the foot. Often, the big toe deviates toward the other toes. When this occurs, the base of the big toe pushes outward on the first metatarsal bone, which is the bone directly behind the big toe, forming a bunion. If this happens on the little toe and fifth metatarsal, it's called a bunionette. Because a bunion occurs at a joint, where the toe bends in normal walking, your entire body weight rests on the bunion at each step. Bunions can be extremely painful. They're also vulnerable to excess pressure and friction from shoes and can lead to the development of calluses.
Causes
Bunions result from the long bone in the foot (metatarsal) and the big-toe bone becoming misaligned. The causes are likely to be a combination of genetics, wearing ill-fitting shoes, and the way that we walk or run. Arthritis sufferers are also prone to bunions.
Symptoms
With the positional change of the hallux, pain is a common occurrence. As the foot goes through the gait cycle the hallux plays an integral role as the body's weight transmits through during propulsion. With this in mind, it easy to see how the change in the hallux joints (metatarsal phalangeal joint and the proximal interphalangeal) would cause joint narrowing and early degeneration of the articular cartilage. In addition, two small bones (ossicles) found underneath just behind the joint will start placing extra pressure on the metatarsal. Along with bony changes, there are many soft tissue changes as the hallux and metatarsal reposition, which causes added strain to other bony structures and can accelerate the problem.
Diagnosis
Generally, observation is adequate to diagnose a bunion, as the bump is obvious on the side of the foot or base of the big toe. However, your physician may order X-rays that will show the extent of the deformity of the foot.
Non Surgical Treatment
Most bunions can be treated without surgery. The first step for treating bunions is to ensure that your shoes fit correctly. Often good footwear is all that is needed to alleviate the problem. Shoes that are wide enough to avoid pressure on the bunion are the obvious first step. Look for shoes with wide insteps and broad toes and definitely no high heels. Sometimes, you can get your existing shoes stretched out by a shoe repairer. Seek advice from a podiatrist. Pads and toe inserts. Protective bunion pads may help to cushion the joint and reduce pain. Toe inserts are available that splint the toes straight. It may be recommended that you wear some orthotics to improve your foot position when walking. Medicines. Some people find anti-inflammatory medicines, such as ibuprofen or aspirin, or paracetamol help ease the pain of their bunions.
Surgical Treatment
The type of surgical procedure performed depends upon the severity of the bunion, the individual?s age, general health, activity level, and the condition of the bones and connective tissue. Other factors may influence the choice of a procedure used. Mild bunion. For this type of surgery, the surgeon may remove the enlarged portion of bone and realign the muscles, tendons, and ligaments surrounding the joint. Moderate bunion. For a moderate bunion, the surgeon may cut the bone and shift it to its proper position. Whether or not the bone is cut depends on the severity and location of the deformity. In addition, the surrounding tendons and ligaments may need to be repositioned. Severe bunion. For a severe bunion, surgery may involve removing the enlarged portion of the bone, cutting and realigning the bone, and correcting the position of the tendons and ligaments. Arthritic bunion or big toe joint. If the joint is damaged beyond repair, as is commonly seen in arthritis, it may need to be reconstructed or replaced with an artificial joint. Joint replacement implants may be used in the reconstruction of the big toe joint.
Prevention
Bunions often become painful if they are allowed to progress. But not all bunions progress. Many bunion problems can be managed without surgery. In general, bunions that are not painful do not need surgical correction. For this reason, orthopaedic surgeons do not recommend ?preventive? surgery for bunions that do not hurt, with proper preventive care, they may never become a problem.
