Every day, someone in the United States loses a limb. According to the Amputee Coalition, 5.6 million Americans are affected by limb loss or limb difference. The leading cause of limb loss can be associated with vascular disease, a condition that can be prevented if treated accordingly.
This article will explore what causes vascular disease, how untreated vascular disease can lead to limb loss, and negative pressure wound therapy’s role in treating vascular disease to prevent limb loss.
Quick Facts from the Amputee Coalition
Limb loss is the permanent removal of a body part due to injury or disease
Limb difference is a condition in which someone has a limb that is different in size, shape, or structure compared to typical limbs
Approximately 2.3 million Americans live with limb loss
Approximately 3.4 million Americans live with limb difference
A 2008 study predicted that by 2050, approximately 3.6 million Americans will be living with limb loss
Toe amputations account for nearly 300,000 limb loss cases
Lower leg amputations account for nearly 200,000 limb loss cases
Limb loss is more common in men as more than 2.2 million cases were reported for men
Vascular Disease Awareness
Vascular disease is a condition that affects the circulatory system or the network of blood vessels. This can include arteries, veins, and capillaries. While vascular disease affects the circulatory system, the specific type of vascular disease may only affect veins, arteries, or a specific part of the body.
The two most common types of vascular disease are Peripheral Artery Disease (PAD) and Carotid Artery Disease (CAD). PAD narrows the arteries in the legs, causing pain when walking. CAD creates a buildup of plaque in the arteries of the neck, resulting in an increased risk of stroke.
Other less common types of vascular diseases are aneurysms, blood clots, deep vein thrombosis, pulmonary embolisms, venous diseases, lymphedema, and vasculitis. Severe cases of vascular disease often led to pain, numbness, and slow-healing sores. With persistent sores that are slow to heal, especially on the feet and legs, individuals increase their risk of lower limb loss.
Negative Pressure Wound Therapy's Role in Preventing Limb Loss
NPWT helps complex wounds heal by creating the right environment for recovery. Using gentle suction, it pulls the wound edges together, removes excess fluid, reduces swelling, and improves blood flow—key factors that help the body repair damaged tissue.
This therapy encourages the growth of healthy new tissue and tiny blood vessels, allowing oxygen and nutrients to reach the wound more easily. As healing improves, the risk of infection and complications decreases, helping reduce the chance of limb loss.
Portability also plays an important role. Traditional wound therapy systems can be bulky and difficult to manage, often limiting movement. Newer options like Cork Medical’s Nisus NPWT system and Versa system are designed for ease of use at home. This allows users to stay mobile, which further improves circulation and supports faster healing.
What's Next?
Preventing diabetic ulcers and vascular disease is the best way to reduce the risk of limb loss, however, solutions like NPWT offer advanced healing methods that can minimize amputations, if caught early.
Explore how NPWT is turning into the world’s leading wound care treatment option for minimizing the risk of limb loss. Clinicians, reach out to the Cork Medical team for information on how the Nisus and Versa NPWT systems are revolutionizing the industry. Patients, talk to your doctor about whether NPWT is right for you.
