Overview
People think of a bunion as being as a bump on the side of the foot near the big toe. However, bunions go deeper than what we can see. Although the skin might be red, a bunion actually reflects a change in the anatomy of the foot. Bunions happen over time. What begins as the big toe pointing toward the second toe ends up as changes in the actual alignment of the bones in the foot. There is also a condition called tailor?s bunion or bunionette. This type of bump differs from a bunion in terms of the location. A tailor?s bunion is found near the base of the little toe on the outside of the foot.
Causes
The underlying cause is a deformity of the joint at the base of the big toe. The deformity is called hallux valgus. In this deformity the joint develops a prominent sideways angle. Due to this deformity the bones of the big toe are pushed towards the smaller toes. The skin over the angled joint then tends to rub on the inside of shoes. This may cause thickening and inflammation of the overlying skin and tissues next to the affected joint. In most cases it is not clear why a hallux valgus deformity develops. There may be some hereditary (genetic) tendency to have a weakness of this joint. In some cases it is associated with a joint problem such as osteoarthritis or rheumatoid arthritis. However, whatever the underlying cause, wearing tight or badly fitting shoes tends to make the problem worse. Wearing such shoes puts extra pressure on the big toe joint and causes friction on the overlying skin.
Symptoms
Symptoms include pain in and around the ball of the big toe, usually from the bone rubbing too much against the shoe. You may be unable to wear certain types of shoes due to the shape of the forefoot. The big toe appears to be bent inwards towards and in come cases over the inside 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
Wide toe box, bunion pads, orthotics, or a combination. Mild discomfort may lessen by wearing a shoe with a wide toe box or with stretchable material. If not, bunion pads purchased in most pharmacies can shield the painful area. Orthotics can also be prescribed to redistribute and relieve pressure from the affected articulation. If conservative therapy fails, surgery aimed at correcting abnormal bony alignments and restoring joint mobility should be considered. If the patient is unwilling to wear large, wider shoes to accommodate the bunion because they are unattractive, surgery can be considered; however, patients should be told that orthotic devices should be worn after surgery to reduce the risk of recurrence. For bursitis, bursal aspiration and injection of a corticosteroid are indicated. For osteoarthritic synovitis, oral NSAIDs or an intra-articular injection of a corticosteroid/anesthetic solution reduces symptoms. For hallux limitus or hallux rigidus, treatment aims to preserve joint mobility by using passive stretching exercises, which occasionally require injection of a local anesthetic to relieve muscle spasm. Sometimes surgical release of contractures is necessary.
Surgical Treatment
Bunion surgery can be performed under local or general anaesthetic. The operation usually takes between half an hour to an hour. There are several types of bunionectomies. Some involve removal and realignment of the bones in your foot. Mild bunion problems can sometimes be resolved using soft tissue release or tightening. For some very severe cases bones of the big toe are fused or the bunion is cut out along with some of the bone at the base of the toe. Be sure and discuss which type of operation you will have with your surgeon. With any type of bunionectomy your surgeon will make one or more incisions (cuts) near your big toe. They will use instruments to trim the bones and remove the bunion. Wire, screws or plates may also be used to hold the new joint in place.
