Separation of the foot from the rest of the leg.
The cause is usually traumatic although it may be secondary to elective surgery.
When amputation is performed in the context of surgery, blood vessels are ligated to prevent bleeding before cutting tissue and cartilage.
The most frequent causes are diseases that cause poor blood circulation, tumours, deformities, infections and/or gangrene.
When the amputation occurs in the context of trauma, bleeding and tissue loss are usually greater. If the limb has been torn off or avulsed, the bleeding can be massive and the surgical repair very difficult. The most frequent causes are traffic or workplace accidents and war injuries.
The treatment of choice is surgical and its priority is to save as much tissue as possible and avoid bleeding and infection. Severe cases can lead to the death of the patient if they are not controlled.
In cases of traumatic amputation, a tourniquet may be used to stop bleeding until surgical revision is performed. If the amputated limb and residual limb are properly cared for, reattachment of the amputated limb in a specialised centre may be considered.
