Bunions are the most common deformity that affects the big toe. A bunion is characterized by angling of the big toe towards the lesser toes, and a painful bump over the inside part of the base of the big toe. This prominence (an area called the medial eminence) is caused by angling inwards of the metatarsal bone, and is not an actual growth of bone.
Bunions are most widely considered to be due to an imbalance in the forces that is exerted across the joint during walking. The resulting abnormal motion and pressure over the joint, over many years (combined with poor fitting footwear) leads to instability in the joint causing hallux valgus and bunions. Bunions are really only a symptom of faulty foot mechanics and are usually caused by a combination of the way we walk, the foot we inherit and inappropriate footwear use.
SymptomsBunions are readily apparent, you can see the prominence at the base of the big toe or side of the foot. However, to fully evaluate your condition, the Podiatrist may take x-rays to determine the degree of the deformity and assess the changes that have occurred. Because bunions are progressive, they don’t go away, and will usually get worse over time. But not all cases are alike, some bunions progress more rapidly than others. There is no clear-cut way to predict how fast a bunion will get worse. The severity of the bunion and the symptoms you have will help determine what treatment is recommended for you.
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
The treatment method your doctor chooses for you will be based on the severity of the bunion. Treatment can be simple and non-surgical or it can be complex, surgical, and costly. A bunion is permanent unless surgery is performed to remove it, but self-care can help to improve your symptoms. If you suspect that a bunion is developing, you should seek medical attention immediately. Here are the most common conservative treatment options. Changing your shoes. Adding custom orthotics to your shoes. Medication such as Tylenol for pain relief. Padding and taping to put your foot in its normal position. Applying ice or cold compresses to reduce swelling and pain. Keeping pressure off your affected toe, especially if there is swelling, redness, and pain. Before bed, separate the affected toe from the others with a foam-rubber pad and leave it there while you sleep.
Bunion surgery is usually done as an out patient procedure, so the patient does not have to stay in hospital overnight although it is usually performed under a general anesthetic. The procedure involves the surgeon making a cut on the inside of the big toe joint and removing excess bone whilst also repositioning ligaments and tendons. The joint may be fixed with screws or wires, which may be dissolve, or may be removed at a later date or in some cases, remain in the foot permanently. After the operation the foot will be immobilized, often in a cast for 4 to 8 weeks to keep the bones in alignment. Crutches will usually be issued to help the patient get around. After this period, the foot will be assessed to check the bones have healed correctly. At which point full weight bearing may be gradually introduced.
