Amputation is the removal of an injured or diseased body part. An amputation may be the result of a traumatic injury, or it may be a planned operation to prevent the spread of the disease in an infected finger or hand. Some traumatically amputated fingers may be replanted or reattached. In many cases, reattachment of the amputated finger is not possible or advisable because the patient will be more comfortable and have better function if the part is not reattached.
