Your big toe is the hardest working toe. Every time your foot pushes off the ground, this toe supports most of your body’s weight. Because the big toe is so critical to movement, any problem with it can make walking or even standing painful. A bunion (excess or misaligned bone in the joint) is one of the most common big-toe problems. In addition to causing pain, a bunion changes the shape of your foot, making it harder to find shoes that fit. But you don’t have to hobble for the rest of your life. Bunions can be treated. With your doctor’s help, your feet can feel and look better.
A true bunion or hallux valgus results from a drifting inwards of the big toe metatarsal from its normal position closer to the second metatarsal. The bunion is the head of this first metatarsal which produces the prominence on the inner side of the now wider foot. Tendons run circumferentially around the metatarsal and toe. They both move and stabilise the toe under normal circumstances. In a bunion or hallux valgus, with the shift/displacement of the first metatarsal these tendons no longer lie in the correct axis and in fact act as a deforming force, contributing to the bunion condition.
SymptomsThe most obvious symptoms of a bunion are. Pain in the area of the MTP joint, the joint where your big toe connects to your foot. Bending of the big toe in towards the other toes. An enlarged bump of bone or tissue at the MTP joint. Each symptom can range in degree from small to severe. Sometimes the pain can be sufficient to make it difficult to walk in normal shoes. Other symptoms may include. Swelling and inflammation of the skin around the MTP joint. Thickening of the skin in the area of the joint. Restricted motion in your big toe. Pressure from the inward bending of your big toe can affect your other toes, leading to corns on your smaller toes. Ingrown toenails on the smaller toes. Development of hammertoes in the other toes. Calluses on the bottom of your foot. If you have any of these symptoms, especially pain, displacement of your big toe or development of a bulge, you should consider consulting your physician. Even if you’re not significantly bothered by some of these symptoms, bunions tend to continue getting bigger and more serious over time and should be taken care of before they do so.
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 bunion may only need to be treated if it’s severe and causing significant pain and discomfort. The different treatments for bunions are described below. If possible, non-surgical treatment for bunions will be used, which your GP can discuss with you. Non-surgical treatments can ease the pain and discomfort caused by a bunion, but they can’t change the shape of your foot or prevent a bunion from getting worse over time. Non-surgical treatments include painkillers, bunion pads, orthotics, wearing suitable footwear, These are discussed in more detail below. If your bunion is painful, over-the-counter painkillers such as paracetamol or ibuprofen may be recommended.Bunion pads may also ease the pain of a bunion. Reusable bunion pads, made of either gel or fleece, are available over the counter from pharmacies. Some are adhesive and stick over the bunion, while others are held against your foot by a small loop that fits over your big toe. Bunion pads stop your foot rubbing on your shoe and relieve the pressure over the enlarged joint at the base of your big toe. Orthotics are placed inside your shoes to help realign the bones of your foot. They may help relieve the pressure on your bunion, which can ease the pain. However, there’s little evidence that orthotics are effective in the long term. It’s important that the orthotic fits properly, so you may want to seek advice from your GP or podiatrist (a specialist in diagnosing and treating foot conditions), who can suggest the best ones for you.
Bunion surgery is most often done on an outpatient or day-surgery basis, usually with a local anesthetic technique called an ankle block. The surgery typically takes an hour or two to perform. Following your surgery, you will stay in the Recovery Room for several hours while the anesthetic wears off. For your safety, you will be required to have someone to drive you home. You should keep in mind that any surgery carries with it very small-but-possible risks of complications such as allergic reaction to anesthesia, bleeding and infection.
To help prevent bunions, select your style and size of shoes wisely. Choose shoes with a wide toe area and a half-inch of space between the tip of your longest toe and the end of the shoe. Shoes also should conform to the shape of your feet without causing too much pressure.
