Bunion is the common term for a medical condition known as Hallux Valgus. Hallux Valgus is the tilting of the toe away from the mid-line of the body. It is usually characterized by a lump or bump that is red, swollen and/or painful on the inside of the foot in and around the big toe joint.
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.
SymptomsA bunion, also called a hallux valgus, is a bony prominence on the inside of the big toe, caused by a misalignment of the joint. The overlying skin maybe swollen, red and tender. Bunions are often painful and can limit what shoes you can wear.
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
A hinged flexible bunion splint, can relieve pain by providing corrective arch support and releasing tension away from the inflamed joint. Change shoes! Avoid flip flops, high-heels and shoes with pointed, narrow toe-boxes. Medicine will not prevent or cure bunions. However, the use of over the counter anti- inflammatory medications can help. Bunion splints, pads and arch supports can help redistribute weight and move pressure away from the big toe.
Sometimes a screw is placed in the foot to hold a bone in a corrected position, other times a pin, wire or plate is chosen. There are even absorbable pins and screws, which are used for some patients. In British Columbia, pins seem to be used most frequently, as they're easier to insert and less expensive. They are typically--but not always--removed at some point in the healing process. But as a general rule, Dr. Schumacher prefers to use screws whenever possible, as they offer some advantages over pins. First, using screws allows you to close over the wound completely, without leaving a pin sticking out of the foot. That allows for a lower infection rate, it allows you to get your foot wet more quickly following the surgery, and it usually allows for a quicker return to normal shoes. Second, they're more stable than pins and wires. Stability allows for faster, more uneventful, bone healing. Third, they usually don't need to be removed down the road, so there's one less procedure involved.
