How Do Amputations Work?

Amputation is a surgical procedure where a limb or part of a limb is removed from the body. It is often considered a last resort treatment option for conditions such as severe trauma, infection, or advanced stages of diseases like diabetes or cancer when other treatments have failed to alleviate the issue or restore function to the affected limb. The practice of amputation dates back almost 36,000 years ago as an almost unsurvivable and desperate method to save human life. However, amputation has evolved as medical technologies advance, significantly reducing the risks for individuals who undergo amputation. 


Causes of Amputation


  • Traumatic Injury:

  • Can include car accidents, workplace incidents, sports-related mishaps, or violent encounters


  • Peripheral Artery Disease (PAD):

  • Involves the blockage of arteries; Reduced blood flow can lead to tissue damage, chronic wounds, and non-healing ulcers


  • Diabetes:

  • Can lead to neuropathy (nerve damage) and peripheral vascular disease (blood vessel damage). 


  • Cancer:

  • Can develop in the bones, muscles, or soft tissues of the limbs; amputation is required when unable to be treated by chemotherapy, radiation therapy, or surgical resection while preserving the affected limb's function.


  • Severe Infections:

  • Can lead to tissue necrosis (death) and gangrene


  • Congenital Abnormalities:

  • Individuals born with limb abnormalities or congenital defects; restricts the development and function of their limbs

  • Severe Frostbite:

  • Causes tissue damage, tissue necrosis and gangrene


Types of Amputation



Although below-the-knee amputations are the most common, amputations also exist in the shoulder, ankle, and other parts.


  • Partial Toe or Finger Amputations

  • Transmetatarsal Amputations

  • removal of the metatarsal bones in the foot to address severe infections, gangrene, or trauma affecting the forefoot

  • Below the Knee (Transtibial) Amputations

  • Above the Knee (Transfemoral) Amputations

  • Partial Hand or Arm Amputations

  • Forequarter Amputation

  • Removal of the entire arm, including the shoulder joint and scapula


The Process of Amputation


After administering anesthesia to the patient, doctors use several methods to decide the area to cut and the amount of tissue required to remove

  • Comparing temperatures of the healthy limb and affected limb

  • Reddened skin

  • Checking the condition and sensitivity of the site

  • Finding a pulse close to the cut site

The procedure involves removing affected tissue and crushed bone, smoothing the uneven areas, sealing off blood vessels and nerves, and shaping muscles for a stump. Surgeons can choose to carry out closed amputation, which involves sewing the skin flaps right away, or leave it open if more tissue needs to be removed in the future.


Recover and Rehabilitation


The loss of a limb can impact people’s mental health, physical health, and their way of life. After amputation occurs, patients enter the rehabilitation process, also known as rehab. 

  •  Immediate Postoperative Care: 

  • comprehensive care to manage pain, prevent infection, and promote healing; including pain medication, wound care, and physical therapy to regain strength and mobility.


  • Prosthetic Fitting 

  • prosthetic devices may be fitted to help restore function and mobility. Prosthetic limbs are custom-designed to fit the individual's residual limb and may include components such as sockets, joints, and feet or hands.


  • Physical Therapy

  • improves strength, flexibility, and coordination. This may include exercises to strengthen muscles, improve balance, and adapt to using a prosthetic limb


  • Psychological Support

  •  Coping with limb loss can be emotionally challenging, and patients may benefit from counseling or support groups to address feelings of grief, loss, and adjustment.
