Injuries - Amputation of lower leg
Anatomy
Amputation is the intentional surgical removal of a limb or body
part. Amputation of the lower leg is also known as below knee amputation or BKA. It is performed
to remove diseased tissue or relieve pain. The goal of all amputations is twofold: to remove
diseased tissue so that the wound will heal cleanly, and to construct a stump that will allow
the attachment of a prosthesis or artificial replacement part. Congenital amputation is the
absence of a fetal limb or fetal part at birth.
Causes
Amputation may be necessary for the following reasons:
 |
To remove tissue that no longer has an adequate
blood supply. |
 |
To remove malignant tumours |
 |
Because of severe trauma to the body part. |
 |
The blood supply to an extremity can be cut off
because of injury to the blood vessel, hardening of the arteries, arterial embolism,
impaired circulation as a complication of diabetes mellitus, repeated severe infection that
leads to gangrene, severe frostbite, Raynaud's disease, or Buerger's disease. |
Congenital amputation may be the result of the constriction of
fibrous bands within the membrane that surrounds the developing fetus, exposure to substances
known to cause birth defects or other factors including genetics.
Treatment
Amputations can be either planned or emergency procedures. Injury
and arterial embolisms are the main reasons for emergency amputations. The operation is
performed under regional or general anaesthesia by a general or orthopaedic surgeon in a
hospital operating room.
The Orthopaedic Leg Trolley offers a practical solution to
increase mobility for below knee amputation. If you would like further details on the
