Amputation

Physical medicine and rehabilitationAmputation is the removal of a limb by trauma, medical illness, or surgery. As a surgical measure, it is used to control pain or a disease process in the affected limb, such as malignancy or gangrene. In some cases, it is carried out on individuals as a preventative surgery for such problems. A special case is that of congenital amputation, a congenital disorder, where fetal limbs have been cut off by constrictive bands. In some countries, amputation of the hands, feet or other body parts is or was used as a form of punishment for people who committed crimes. Amputation has also been used as a tactic in war and acts of terrorism; it may also occur as a war injury. In some cultures and religions, minor amputations or mutilations are considered a ritual accomplishment. Amputation is the removal of a limb by trauma, medical illness, or surgery.

The amputated person is called an amputee. In the US, the majority of new amputations occur due to complications of the vascular system (the blood vessels), especially from diabetes. Between 1988 and 1996, there were an average of 133,735 hospital discharges for amputation per year in the US. In 2005, just in the US, there were 1.6 million amputees. In 2013, the US has 2.1 million amputees. Approximately 185,000 amputations occur in the United States each year. In 2009, hospital costs associated with amputation totaled more than $8.3 billion. There will be an estimated 3.6 million people in the US living with limb loss by 2050. African Americans are up to four times more likely to have an amputation than European Americans. Lower limb amputations can be divided into two broad categories: minor and major amputations. Minor amputations generally refer to the amputation of digits. Major amputations are commonly below-knee- or above-knee amputations Common partial foot amputations include the Chopart, Lisfranc, and ray amputations. Common forms of ankle disarticulations include Pyrogoff, Boyd, and Syme amputations. A less common major amputation is the Van Nes rotation, or rotationplasty, i.e. the turning around and reattachment of the foot to allow the ankle joint to take over the function of the knee.
