A bunion is a bony bump on the joint at the base of your big toe. The bony growth on the joint sometimes causes your big toe to Bunion Surgery at Nuffield Health Hospitalsturn in towards your second toe. Symptoms include pain, swelling of your big toe and, as the bunion sticks out, it can often rub on the inside of your shoe. The cause is not always known, there may be a deformity of the joint, called hallux valgus (hallux means big toe, valgus means bent outwards). Or it can be as simple as ill fitting footwear not allowing enough width to fit the toes in their natural position. Sometimes bunions are associated with arthritis in the joint at the base of your big toe. Left untreated bunions can continue to grow and become more painful.
The underlying cause is a deformity of the joint at the base of the big toe. The deformity is called hallux valgus. In this deformity the joint develops a prominent sideways angle. Due to this deformity the bones of the big toe are pushed towards the smaller toes. The skin over the angled joint then tends to rub on the inside of shoes. This may cause thickening and inflammation of the overlying skin and tissues next to the affected joint. In most cases it is not clear why a hallux valgus deformity develops. There may be some hereditary (genetic) tendency to have a weakness of this joint. In some cases it is associated with a joint problem such as osteoarthritis or rheumatoid arthritis. However, whatever the underlying cause, wearing tight or badly fitting shoes tends to make the problem worse. Wearing such shoes puts extra pressure on the big toe joint and causes friction on the overlying skin.
Symptoms of a bunion include irritated skin, sensitivity to touch, and pain when walking or running. Since the bunion may grow so prominent as to affect the shape of the foot, shoes may no longer fit properly, and blisters may form at the site of friction and pressure. Bunions may grow so large that an individual must wear shoes that are a larger size than they would otherwise wear. If the bunion becomes a severe case, walking may become difficult.
Clinical findings are usually specific. Acute circumferential intense pain, warmth, swelling, and redness suggest gouty arthritis (see Gout) or infectious arthritis (see Acute Infectious Arthritis), sometimes mandating examination of synovial fluid. If multiple joints are affected, gout or another systemic rheumatic disease should be considered. If clinical diagnosis of osteoarthritic synovitis is equivocal, x-rays are taken. Suggestive findings include joint space narrowing and bony spurs extending from the metatarsal head or sometimes from the base of the proximal phalanx. Periarticular erosions (Martel sign) seen on imaging studies suggest gout.
Non Surgical Treatment
Changing your footwear to roomy and comfortable shoes that provide plenty of space for your toes. Padding and taping applied by chiropodist/podiatrist to your foot can reduce stress on the bunion and alleviate your pain. Oral medications such as acetaminophen (Tylenol), ibuprofen (Advil, Motrin) or naproxen (Aleve) may help control the pain of a bunion. Cortisone injections. Over-the-counter arch supports can help distribute pressure evenly when you move your feet, reducing your symptoms and preventing your bunion from getting worse. Prescription foot orthotic devices to help stabilize the forefoot. Manual foot therapy to free up motion in arthritic foot joints.
In cases where joint pain and deformity are severe, joint replacement surgery may be recommended. This may particularly be recommended when arthritis is present in the joint. Surgery may be carried out under a local, regional or general anaesthetic. Most cases are performed as a day stay procedure. However, an overnight stay in hospital may be required if the surgery is more extensive. The type of surgery to be performed, the type of anaesthetic to be used and the expected hospital stay should be discussed with your surgeon prior to surgery.
