Definition
A bunionectomy is a surgical procedure to excise, or remove, a bunion. A bunion is an enlargement of the joint at the base of the big toe and is comprised of bone and soft tissue. It is usually a result of inflammation and irritation from poorly fitting (narrow and tight) shoes in conjunction with an overly mobile first metatarsal joint and over-pronation of the foot. Over time, a painful lump appears at the side of the joint, while the big toe appears to buckle and move sideway towards the second toe. New bone growth can occur in response to the inflammatory process, and a bone spur may develop. Therefore, the development of a bunion may involve soft tissue as well as a hard bone spur. The intense pain makes walking and other activities extremely difficult. Since the involved joint is a significant structure in providing weight-bearing stability, walking on the foot while trying to avoid putting pressure on the painful area can create an unstable gait.

Hallux valgus is a condition in which the big toe migrates laterally toward the second toe. This results in a bump on the inner side of the foot, know as a bunion. It is related to a combination of genetic factors, activities, and inheritance. Some patients who have this condition do not have symptoms. Sometimes symptoms can be relieved just by modifying the shoe to have enough room in the forefoot to accommodate the changed shape.

Persons with diabetes, be it type 1 or 2, are individuals who share a common disease that causes high blood sugars. The effects of the high blood sugars will vary from person to person. Likewise diabetes will affect the feet of each individual person with diabetes in a different manner. Some persons with diabetes have a high risk for foot problems, whereas others are not really at increased risk for foot problems. It is extremely important to screen persons with diabetes to find out who is at increased risk for foot problems. Those who are at increased risk require specialized foot care in order to lower the risk for foot problems. Any person with diabetes should be in the habit of removing his/her shoes and socks upon entering his/her health care providers examining room so that the feet will not be overlooked.

Calluses are thick skin that forms in response to repeated pressure over a course of time. Blisters are fluid filled pockets that are also the result of increased pressure but typically the pressure is more intense and for a shorter period of time than the pressure that causes a callus. The roof of a blister is typically very thin because there is not enough time to form a thick callus. Calluses form over pressure points to protect the skin from injury. Without calluses the skin is more prone to blisters.
If calluses are protective then why is there so much concern about calluses on the soles of a person with diabetes?
Calluses form to protect the skin; however, in persons with diabetes the body does not know how much callus to lay down and the callus is different. Elevated blood sugars affect the skin and cause thicker and harder calluses.

FOOT INFECTIONS
Understanding the Do's and Don'ts of Diabetic Foot Care.
Persons with diabetes routinely attend diabetes teaching clinics where they receive valuable diabetes education. A lot of different information is presented including lists of Do’s and Don’ts of foot care. In order to follow or adhere to a list of do’s and don’ts of foot care it is important to understand the list. As a diabetic foot care specialist I commonly ask new patients what they have learned about foot care. Some are able to repeat a list of do’s and don’ts. When I respond by asking, “Why should do this or why shouldn’t you do that?” the common answer is because, “If I don’t I could lose my leg or Uncle Joe lost a leg to diabetes…”
It is a fact that persons with diabetes have a higher risk for leg amputation than persons without diabetes. It is also true that persons with diabetes are individuals. The effect of diabetes will vary from individual to individual. Likewise the feet will be affected on an individual basis. Some persons will be at extremely high risk for foot problems and amputation; whereas, others may not be at much more risk than an average person without diabetes.
