Many people don't realize that the foot and leg pain, which they assume to be because of a momentary uneasiness or simply due to increase in age, could actually be something far more serious, and often avoidable.
People especially, diabetics could be at a risk for amputation when they neglect foot and leg pain. Around 20.8 million people suffer from diabetes in the U.S. According to the Centers for Disease Control the number of diabetes-related lower limb amputations has risen by 227 % between 1980 (33,000) and 2003 (75,000).
Diabetics are prone to amputation as the condition often causes blood vessels in the foot and leg to narrow, causing poor circulation. This makes diabetics susceptible to infection, making it difficult for these wounds to heal. In fact, nine out of 10 non-traumatic lower extremity amputations are instigated by an infection, according to a study led by Texas A&M University. The American Diabetes Association says that diabetes is the most frequent cause of non-traumatic lower limb amputations.
The unfortunate result of these trends is that each year, 75,000 people lose their foot, leg or toe due to diabetes, and 85 percent of these losses could have been avoided, according to the International Diabetes Federation.
New Laser Treatment is an Option in the Fight Against Amputation
Physicians now have a new tool in the fight against amputation. The CLiRpath "cool" excimer laser and catheter procedure vaporizes total arterial blockages that cannot be crossed by standard guidewires (small, flexible wires used to position catheters) in leg and foot arteries, restoring straightline blood flow, which promotes healing. Developed by Spectranetics Corp. (NASDAQ: SPNC), the minimally invasive CLiRpath procedure often enables patients to leave the hospital the day after the treatment. CLiRpath has been the subject of rigorous clinical trials, with limb salvage observed in 95 percent of patients surviving to six months(1).
"Among all the complications from diabetes, amputation can be the worst," said Dr. Craig Walker, of the Cardiovascular Institute of the South, in Houma, La., and one of the country's leading clinical investigators and cardiologists. "Amputation affects a person's quality of life drastically, from mobility to self-image. It is also associated with a decreased life expectancy. But, many amputations can be avoided by simply monitoring the symptoms and talking to a physician about your pain."
Common Warning Signs
The frequent culprit of diabetic amputations is peripheral arterial disease (PAD), in which plaque blocks foot or leg arteries, resulting in pain, development of ulcers and onset of limb loss. According to the American College of Cardiology, common symptoms of PAD are:
· Discomfort, cramping or heaviness in the toes, feet or legs
· Poorly healing or non-healing wounds on the toes, feet or legs
· Walking impairment
· Pain at rest that is localized to the lower leg or foot
· Abdominal pain that is provoked by eating
· Familial history of a first-degree relative with an abdominal aortic aneurysm
One Man's Story
In 1958, Tom Nelson decided to move from Minnesota to Colorado as a result of his love for the outdoors. Now in his mid-70s, Montrose, Colo., resident Nelson noticed exhaustion and increasing pain in his legs beginning to affect his day-to-day activities. No longer able to take his daily three-mile walks, Nelson's doctor detected arterial blockages in both legs. Fearing the worst, Nelson thought he would be bedridden or possibly facing amputation. This condition (frequently diagnosed as the most severe form of PAD, called Critical Limb Ischemia) is common in older people and particularly diabetics, affecting over 1 million people in the U.S. each year.
His doctor sent Nelson to Dr. Walker to undergo the CLiRpath procedure. Unlike bypass surgery or angioplasty and stenting techniques, the CLiRpath laser can vaporize blockages in the arteries in the leg and foot. Dr. Walker performed the procedure on both of Nelson's legs in February 2006. After a brief hospital stay, Nelson was released.
Nelson has had a stellar recovery since undergoing the CLiRpath procedure. At 75, he is now able to resume his vigorous physical activities, including mowing his 5,000-square-foot lawn without pain.
"Mr. Nelson's case shows that anyone, no matter how healthy, can suffer from arterial blockages in the legs," said Dr. Walker. "Loss of mobility is not always a condition of getting old. Many amputations can be prevented."
