Overview
Bunions Hard Skin
The term hallux valgus actually describes what happens to the big toe. Hallux is the medical term for big toe, and valgus is an anatomic term that means the deformity goes in a direction away from the midline of the body. So in hallux valgus the big toe begins to point towards the outside of the foot. As this condition worsens, other changes occur in the foot that increase the problem. One of those changes is that the bone just above the big toe, the first metatarsal, usually develops too much of an angle in the other direction. This condition is called metatarsus primus varus. Metatarsus primus means first metatarsal, and varus is the medical term that means the deformity goes in a direction towards the midline of the body. This creates a situation where the first metatarsal and the big toe now form an angle with the point sticking out at the inside edge of the ball of the foot. The bunion that develops is actually a response to the pressure from the shoe on the point of this angle. At first the bump is made up of irritated, swollen tissue that is constantly caught between the shoe and the bone beneath the skin. As time goes on, the constant pressure may cause the bone to thicken as well, creating an even larger lump to rub against the shoe.


Causes
Despite the popular belief, wearing high heels and too-narrow shoes does not cause bunions. Wearing them can irritate, aggravate, or accelerate the formation of the bunion, but are not the root cause. Bunions are more commonly inherited, if your parents or grandparents had bunions, you may also get one. Bunions can also be caused by trauma or injury to the joints, ligaments, or bones of the foot.


Symptoms
Symptoms, which occur at the site of the bunion, may include pain or soreness, inflammation and redness, a burning sensation, possible numbness. Symptoms occur most often when wearing shoes that crowd the toes, such as shoes with a tight toe box or high heels. This may explain why women are more likely to have symptoms than men. In addition, spending long periods of time on your feet can aggravate the symptoms of bunions.


Diagnosis
Your doctor can identify a bunion by examining your foot. Watching your big toe as you move it up and down will help your doctor determine if your range of motion is limited. Your doctor will also look for redness or swelling. After the physical exam, an X-ray of your foot can help your doctor identify the cause of the bunion and rate its severity.


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.
Bunion Pain


Surgical Treatment
Surgery takes place either under local or general anaesthetic and takes about one hour. After surgery you will have either a plaster cast or special dressing on the foot and you will be given a special walking shoe and crutches to use the first few days/weeks. Recovery usually takes approximately 6-8 weeks but swelling often lasts longer and it may take a few months before you are able to wear normal shoes again. Full recovery can take up to a year. Bunion surgery is successful in approximately 85% of cases, but it is vital not to go back to wearing ill-fitting shoes else the problem is likely to return.


Prevention
If the diagnosis is made early on, such as in preadolescence, bunion development can be slowed and in some cases arrested with the proper supportive shoe gear and custom functional shoe inserts (orthotics). Avoidance of certain athletic activities with improper shoe fit and toe pressure can prevent the symptoms that occur with bunions.
