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.
Inflammatory joint diseases. Those who suffer from rheumatoid and psoriatic arthritis are at risk for bunions, although many times, those who suffer from bunions will mistakenly attribute the soreness in their feet to arthritis. Genetic and neuromuscular factors. Individuals with Down?s Syndrome are believed to be more prone to developing bunions; therefore, the gait and feet of such patients should be examined carefully and regularly so that any problems can be caught and treated early. Similarly, individuals of any age who have been diagnosed with Ehlers-Danlos or Marfan?s Syndrome, have also been shown to have a higher than average occurrence of bunions. Limb inequality. Individuals who have legs of unequal length often suffer from bunions on the longer limb due to the irregular mechanics of their walking or running gait.
SymptomsYour bunion may not cause any symptoms. Or you may have pain in your big toe, red or irritated skin over the bunion, and swelling at the base of the big toe. The big toe may point toward the other toes and cause problems in other toes, such as hammer toe . A bunionette can cause similar symptoms at the base of the little toe.
Looking at the problem area on the foot is the best way to discover a bunion. If it has the shape characteristic of a bunion, this is the first hint of a problem. The doctor may also look at the shape of your leg, ankle, and foot while you are standing, and check the range of motion of your toe and joints by asking you to move your toes in different directions A closer examination with weight-bearing X-rays helps your doctor examine the actual bone structure at the joint and see how severe the problem is. A doctor may ask about the types of shoes you wear, sports or activities (e.g., ballet) you participate in, and whether or not you have had a recent injury. This information will help determine your treatment.
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.
This involves surgically correcting the deformity and can involve a variety of different methods. However, outcomes can be variable. This is very dependant of the amount of damage to the joint and the procedure used to correct it. Removal of the bunion is performed using different methods that are out of the scope of this article. Unfortunately, bunions can recur following surgery, and even if it surgery is successful, around 30% of patients still report existing difficulties.
