A bunion (hallux valgus) is a deformity of the base joint of the big toe. The cause is not clear in many cases. The deformity may cause the foot to rub on shoes, which may cause inflammation and pain. Good footwear is often all that is needed to ease symptoms. An operation to correct the deformity is an option if good footwear does not ease symptoms. Causes
Many problems that occur in the feet are the result of abnormal pressure or rubbing. One way of understanding what happens in the foot due to abnormal pressure is to view the foot simply. Our simple model of a foot is made up of hard bone covered by soft tissue that we then put a shoe on top of. Most of the symptoms that develop over time are because the skin and soft tissue are caught between the hard bone on the inside and the hard shoe on the outside. Any prominence, or bump, in the bone will make the situation even worse over the bump. Skin responds to constant rubbing and pressure by forming a callus. The soft tissues underneath the skin respond to the constant pressure and rubbing by growing thicker. Both the thick callus and the thick soft tissues under the callus are irritated and painful. The answer to decreasing the pain is to remove the pressure. The pressure can be reduced from the outside by changing the pressure from the shoes. The pressure can be reduced from the inside by surgically removing any bony prominence. 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
When an x-ray of a bunion is taken, there is usually angulation between the first metatarsal bone and the bones of the big toe. There may also be angulation between the first and second metatarsal bones. These angular irregularities are the essence of most bunions. In general, surgery for bunions aims to correct such angular deformities. Non Surgical Treatment
The non-invasive treatments for bunions are many and include changes in footwear, icing the sore area, over the counter pain medications, orthotic shoe inserts, and weight management. If these conservative measures fail to arrest your pain and discomfort, your foot and ankle surgeon may recommend a bunionectomy or similar surgical procedure, depending on your condition. Surgical Treatment
Several surgical procedures are available to the podiatric physician The surgery will remove the bony enlargement, restore the normal alignment of the toe joint, and relieve pain.A simple bunionectomy, in which only the bony prominence is removed, may be used for the less severe deformity. Severe bunions may require a more involved procedure, which includes cutting the bone and realigning the joint. Recuperation takes time, and swelling and some discomfort are common for several weeks following surgery. Pain, however, is easily managed with medications prescribed by your podiatric physician.
