A bunion is an enlargement of the joint at the base of the big toe (the metatarsophalangeal or MTP joint) that forms when the bone or tissue moves out of place. The toe bends inward at an awkward angle, which usually creates a large bone lump. If not treated, bunions can become very painful since this area supports a lot of body weight. The MTP joint can also become sore and stiff. Bunions can occur on the outside of the little toe as well.
You are usually born with a foot type that leads to bunion formation. Flat feet with increased flexibility are most likely to form bunions. Abnormal mechanics increase the bunion formation over time. Other causes of bunions include osteoarthritis, gout, rheumatoid arthritis, trauma, and neurovascular disease.
The major symptom of bunions is a hard bump on the outside edge of the foot or at the base of the big toe. Redness, pain and swelling surrounding or at the MTP joint can also occur.
Orthopaedic surgeons diagnose bunions on the basis of physical examination and weight bearing x-rays. Two angles are assessed, the intermetatarsal angle, that is between the first and second metatarsals (the bones that lead up to the base of the toes). If this angle exceeds 9? (the angle found in the healthy foot) it is abnormal and referred to as metatarsus primus varus. the hallux valgus angle, that is, the angle of the big toe as it drifts toward the small toe. An angle that exceeds 15? is considered to be a sign of pathology.
Non Surgical Treatment
The first step in the treatment of Bunions, Corns, and Calluses is determining what is causing the problem. Check with your family doctor or Podiatrist (foot doctor) to find the best solution for your ailment. You can reduce the risk of Bunions, Corns, and Calluses by following these simple instructions. Wear properly-fitting footwear, socks, and stockings (not too tight or too loose). Wear footwear with a wide toe box (toe area). Wear footwear or arch supports which provide proper support, weight distribution, and shock absorption. Maintain a healthy weight. For early-stage Bunions, soaking your feet in warm water can provide temporary relief.
If non-surgical treatments fail to relieve bunion pain and when the pain of a bunion interferes with daily activities, it?s time to discuss surgical options with a foot and ankle surgeon. Together you can decide if surgery is best for you. A variety of surgical procedures is available to treat bunions. The procedures are designed to remove the ?bump? of bone, correct the changes in the bony structure of the foot, and correct soft tissue changes that may also have occurred. The goal of surgery is the reduction of pain. In selecting the procedure or combination of procedures for your particular case, the foot and ankle surgeon will take into consideration the extent of your deformity based on the x-ray findings, your age, your activity level, and other factors. The length of the recovery period will vary, depending on the procedure or procedures performed.
