Overview
Bunions are one of the more serious conditions that can affect foot health. A bunion is actually a bone deformity of the big toe, where the joint at the base and side of the toe is enlarged, forcing the toe out of place. Left untreated, bunions worsen over time. The big toe angles in toward the rest of the toe, and can overlap the third toe (a condition known as Hallux Valgus). Or, it may move toward the second toe and twist or rotate (Hallus Abducto Valgus). Bunions can also lead to deformities like hammertoes. Bunions cause discomfort and pain, because the enlargement constantly rubs against footwear. The skin of the toe becomes red and tender. The larger a bunion grows, the more painful it is to walk. People with bunions can develop thickening skin on the bottom of the foot, bursitis or arthritis, and chronic pain.
Causes
Bunions develop when the pressures of bearing and shifting your weight fall unevenly on the joints and tendons in your feet. This imbalance in pressure makes your big toe joint unstable, eventually molding the parts of the joint into a hard knob that juts out beyond the normal shape of your foot. Experts disagree on whether tight, high-heeled or too-narrow shoes cause bunions or whether footwear simply contributes to bunion development. Other causes include inherited foot type, foot injuries, deformities present at birth (congenital). Bunions may be associated with certain types of arthritis, particularly inflammatory types, such as rheumatoid arthritis. An occupation that puts extra stress on your feet or one that requires you to wear pointed shoes also can be a cause.
Symptoms
It is unusual to have much bunion or hallux valgus pain when out of shoe wear or at rest. There are exceptions to this and in particular if symptoms have been ignored during the day and the bunion has become very painful during the day then some symptoms may be present at night. The pain from the region of the great toe at rest or at night is however more often a symptom of an arthritic big toe (hallux rigidus) rather than a straightforward bunion. To confuse matters these two conditions can sometimes coexist. Bunion or hallux valgus pain is most often present when walking in enclosed shoes. There may be little bunion pain in sandals or barefoot. It is unusual to have much bunion pain when not putting weight on the foot or at night. If there is bunion pain at rest or at night then there may also be arthritic change within the toe.
Diagnosis
Looking at the problem area on the foot is the best way to discover a bunion. If it has the shape characteristic of a bunion, this is the first hint of a problem. The doctor may also look at the shape of your leg, ankle, and foot while you are standing, and check the range of motion of your toe and joints by asking you to move your toes in different directions A closer examination with weight-bearing X-rays helps your doctor examine the actual bone structure at the joint and see how severe the problem is. A doctor may ask about the types of shoes you wear, sports or activities (e.g., ballet) you participate in, and whether or not you have had a recent injury. This information will help determine your treatment.
Non Surgical Treatment
Initial treatment of bunions may include wearing comfortable, well-fitting footwear (particularly shoes that conform to the shape of the foot and do not cause pressure areas) or the use of splints and orthotics (special shoe inserts shaped to your feet) to reposition the big toe. For bunions caused by arthritis, medications may help reduce pain and swelling. If nonsurgical treatment fails, your doctor may suggest surgery, which resolves the problem in nearly all persons. The goal of surgery is to relieve pain and correct as much deformity as possible. The surgery is not cosmetic and is not meant to improve the appearance of the foot. Other related procedures that may be used to help diagnose foot disorders include X-rays of the bone and foot.
Surgical Treatment
Surgery is a last option for those with advanced and painful bunions that do not respond to any other treatment. The surgical operation to correct the deformity from a bunion is called a bunionectomy, which typically involves removing bony growth of the bunion, re-positioning ligaments and tendons, and realigning the bones of the toe joint. Surgery is usually a day procedure performed with a local anaesthetic. The bones may be stabilised in their new position with screws or pins. Hardware may even include absorbable pins that are broken down by the body after a few months. You can expect a 6 - 8 week recovery period during which crutches are usually required. Surgery is often successful but sometimes the big toe moves back to its previous deviated position. Proper footwear and orthotics reduces the chances of surgical failure.
