Intense pain at the first joint of the big toe is what most commonly brings the patient to the doctor. Loss of toe mobility may also have occurred. Severe deformity of the foot may also make it almost impossible for the patient to fit the affected...

foot into a shoe. The condition may be in either foot or in both. In addition, there may be a crackling sound in the joint when it moves. Diagnosis of a bunion is based on a physical examination, a detailed history of the patient's symptoms and their development over time, and x rays to determine the degree of deformity. Other foot disorders such as gout must be ruled out. The patient history should include factors that increase the pain, the patient's level of physical activity, occupation, amount of time spent on his or her feet, the type of shoe most frequently worn, other health conditions such as diabetes that can affect the body's ability to heal, a thorough medication history, including home remedies, and any allergies to food, medications, or environmental aspects. The physical exam should include an assessment while standing and walking to judge the degree to which stability and gait have been affected, as well as an assessment while seated or lying down to measure range of motion and anatomical integrity. An examination of the foot itself will check for the presence of unusual calluses, which indicate abnormal patterns of friction. Circulation in the affected foot will be noted by checking the skin color and temperature. A neurological assessment will also be conducted.

Conservative measures are usually the first line of treatment and target dealing with the acute phase of the condition, as well as attempting to stop the progression of the condition to a more serious form. Measures may include:

• rest and elevation of the affected foot
• eliminating any additional pressure on the tender area, perhaps by using soft slippers instead of shoes
• soaking the foot in warm water to improve blood flow
• use of anti-inflammatory oral medication
• an injection of a steroidal medication into the area surrounding the joint
• systematic use of an orthotic, either an over-the-counter product or one specifically molded to the foot
• the use of a cushioned padding against the joint when wearing a shoe

If these measures prove unsuccessful, or if the condition has worsened to significant foot deformity and altered gait, then a bunionectomy is considered. The doctor may use the term hallux valgus when referring to the bunion. Hallux means big toe and valgus means bent outward. In discussing the surgical option, it is important for the patient to clearly understand the degree of improvement that is realistic following surgery.

X rays to determine the exact angle of displacement of the big toe and potential involvement of the second toe will be taken. The angles of the two toes in relation to each other will be noted to determine the severity of the condition. Studies in both a standing as well as a seated or lying down position will be considered. These will guide the surgeon at the time of the surgery as well. In addition, blood tests, an EKG, and a chest x-ray will most likely be ordered to be sure that no other medical condition has gone undiagnosed that could affect the success of the surgery and the patient's recovery.
