Amputation

There are a number of factors that influence the risk of complications from amputation, such as your age, the type of amputation and your general state of health.

Recovery

After surgery, you will be transferred back to a ward. You will normally be given oxygen through a mask and nutrients and fluids through a drip for the first few days after surgery.

Your amputation wound will be covered with a bandage or plaster dressing and a tube may be placed under the skin next to the wound to drain away any excess fluid from the site of the surgery. This will help prevent excessive bruising and swelling at the wound. It is usually recommended that the bandage remains in place for the first five days to reduce the risk of infection.

A small flexible tube, known as an urinary catheter, may be placed in your bladder during your surgery to drain away urine. This means you will not need to worry about going to the toilet for the first few days after surgery.

It is likely that you will experience considerable pain at the site of the operation, so painkillers will be supplied as required. Let your pain nurse know if the painkillers are not working as you may need a larger dose or a stronger type of painkiller.

Preparing for discharge

As you gradually recover from the effects of surgery, you will meet a number of different health professionals, such as a social worker, occupational therapist and physiotherapist, to help plan for your discharge.

Your physiotherapist will also teach you a number of exercises to help prevent blood clots and improve blood supply.

Compression shrinker sock

You will notice swelling (oedema) of your stump after surgery, which is normal. This swelling can also continue once you have been discharged.

Using a compression shrinker sock will help with swelling and the shape of the stump. It may also reduce phantom pain and give a feeling of support to the limb.

Your physiotherapist will measure you for your sock once your wound has healed and the sock can be placed over your stitches.

The sock should be worn every day, but taken off before you go to bed. It is important to wash the sock regularly (every 2-3 days) and you should be supplied with at least two socks.

Going home

How long it will take before you are ready to go home will depend on the type of amputation you have and your general state of health.

In many parts of the country it is common to be transferred to another hospital or ward for a period of rehabilitation following a leg amputation. This is usually done when you no longer require the facilities of the surgical ward.

Before you leave home, it is likely that an occupational therapist will arrange a visit to see if any aids are needed to make your home environment more accessible, such as a wheelchair ramp or a stairlift. If these kinds of modifications are required, the issue can be referred to your local social services department.

It can take several months before you are fitted with a prosthetic limb, or a prosthetic limb may not be suitable for you (see below for more information on prosthetics), so you may be given a wheelchair if you had a lower limb amputation.

You may also have meetings with a social worker to see if you need any additional support at home, such as meals on wheels. Also, a dietitian can advise on changes you can make to your diet to cope with the extra energy requirements you may have if using a prosthetic limb.

You will probably be asked to attend a follow-up appointment two weeks after leaving hospital to discuss how well you are coping at home and whether you require additional help, support or equipment.

You may also be given details of your nearest amputee support group, made up of both health professionals and people living with an amputation. Most amputee support groups meet once a month.

Fitting the prosthetic

A prosthetic limb is not suitable for everyone, especially a lower prosthetic limb. Using a prosthetic limb takes a considerable amount of energy because you have to compensate for loss of muscle and bone in the amputated limb.

For example, a person fitted with a prosthetic limb after a transfemoral (above-knee) amputation has to use 80% more energy to walk than a person with two legs. So if it is thought your body would not withstand the strain of using a prosthetic limb – for example, if you had a heart condition – then a purely cosmetic limb may be recommended instead (a limb that looks like a real limb but cannot be used).

If you are a suitable candidate for a prosthetic limb, you will begin a programme of activities while still in hospital to prepare for the prosthetic.

Before a prosthetic is fitted, the skin covering your stump may be made less sensitive (known as desensitisation). This will make the prosthetic more comfortable to wear.

Skin desensitisation consists of the following steps:

  • gently tapping the skin with a face cloth
  • using compression bandages to help reduce swelling and prevent a build-up of fluid inside and around your stump
  • rubbing and pulling the skin around your bone to prevent excessive scarring

Your physiotherapist will teach you a range of exercises designed to strengthen muscles in the remainder of your limb while also improving your general energy levels, so you can cope better with the demands of an artificial limb.

Depending on the level of provision in your local primary care trust, it can take several months before you get your first appointment with a prosthetist (specialist in prosthetic limbs).

Lower limb prosthetic

There is a large range of lower limb prosthetics. Most lower limb prosthetics consist of the components listed below:

  • The socket is the interface between your prosthetic limb and the remainder of your real limb. The most common type of socket used in lower limb prosthetics is known as a patellar tendon-bearing socket, which is a plaster mould designed to fit around the knee joint
  • A suspension system keeps the prosthetic limb in place. Examples of suspension systems include strapping systems and suction cups
  • Artificial joints are a type of metal hinge designed to replicate the function and range of movement of real joints, such as the knee or ankle joints
  • A pylon is a metal rod designed to replicate the function of the main bones of the leg
  • A prosthetic foot is made from metal, plastic or a combination of both and is designed to replicate the main functions of the real foot, such as bearing the weight of the limb and aiding balance and stability

Upper limb prosthetics

Again, there is a wide range of upper limb prosthetics, which generally consist of the components listed below.

  • The socket is usually made from lightweight plastic or graphite (a type of lightweight mineral) designed to fit around the remaining limb, which in most cases is a section of the arm just below the elbow joint
  • A suspension system, either a strapping or suction system, keeps the limb in place
  • A control mechanism is designed to replicate the movements of the arm and hand. One commonly used type of control system is to attach cables to muscles in other parts of your body, such as your shoulder or upper arm. You learn a range of movements that allow you to control the prosthetic limb. Alternatively, the control mechanism can be electric and controlled by electrodes implanted in your arm, which respond to the electrical activity generated by certain muscles
  • A terminal device serves as the ‘hand’ of the prosthetic limb. Terminal devices have tended to either be physically realistic and cosmetically pleasing but with little practical function, or look very artificial (such as a hook or a claw) but with a wide range of potential functions. More sophisticated terminal devices are now being developed that are both cosmetically pleasing and functional

Stump care

It is important to keep the skin on the surface of your stump clean to reduce the risk of the skin becoming irritated or infected.

Wash your stump at least once a day (more frequently in hot weather) with a mild antibacterial soap and warm water, and dry it carefully.

If you regularly take baths, do not leave your stump submerged in water for long periods of time. This is because the water will soften the skin on the stump, making it more vulnerable to injury.

Using unmedicated talcum powder, such as baby talcum powder, is an effective way to help reduce perspiration (sweat) around your stump.

Some people find wearing one or more socks around their stump can also help absorb perspiration and reduce skin irritation. As the size of the stump may change during recovery as swelling goes down, the number of socks used may vary. However, it is important to change the socks every day to maintain a hygienic environment.

If you have a prosthetic limb, clean the socket regularly with soap and warm water.

Check your stump carefully every day for any sign of infection such as:

  • warm, red and tender skin
  • discharge of fluid or pus
  • swelling of the skin

If you think you may be developing a skin infection, contact your care team for advice.

Care of your remaining limb

After losing a leg, it is very important to avoid injury and damage to your remaining 'good' leg, particularly if you are diabetic, as the conditions that led to the need for amputation may also be present in the remaining leg.

You should ensure that you avoid poorly fitting footwear, and that an appropriately trained individual (such as a chiropodist) is involved in nail care and other aspects of the care of your remaining foot.

Amputation

An amputation is the surgical removal of part of the body, such as an arm or leg.

Why amputation may be needed

An amputation may be needed if:

  • you have a severe infection in your limb
  • your limb has been affected by gangrene (often as a result of peripheral arterial disease)
  • there's serious trauma to your limb, such as a crush or blast wound
  • your limb is deformed and has limited movement and function

Assessment before surgery

Unless you need to have an emergency amputation, you'll be fully assessed before surgery to identify the most suitable type of amputation and any factors that may affect your rehabilitation.

The assessment is likely to include:

  • a thorough medical examination – assessing your physical condition, nutritional status, bowel and bladder function, your cardiovascular system (heart, blood and blood vessels) and your respiratory system (lungs and airways)
  • an assessment of the condition and function of your healthy limb – removing one limb can place extra strain on the remaining limb, so it's important to look after the healthy limb
  • a psychological assessment – to determine how well you'll cope with the psychological and emotional impact of amputation, and whether you'll need additional support
  • an assessment of your home, work and social environments – to determine whether any additional provisions will need to be made to help you cope

You'll also be introduced to a physiotherapist, who will be involved in your post-operative care. A prosthetist (a specialist in prosthetic limbs) will advise you about the type and function of prosthetic limbs or other devices available.

If you're having a planned amputation, you might find it reassuring to talk to someone who's had a similar type of amputation. A member of your care team may be able to put you in touch with someone.

How amputations are carried out

Amputations can be carried out under general anaesthetic (where you're unconscious) or using an epidural anaesthetic (which numbs the lower half of the body).

Once the limb has been removed, a number of additional techniques can be used to help improve the function of the remaining limb and reduce the risk of complications.

These include shortening and smoothing the bone in your remaining limb so it's covered by an adequate amount of soft tissue and muscle, and stitching the remaining muscle to the bones to help strengthen your remaining limb (a technique known as myodesis).

After the amputation, your wound will be sealed with stitches or surgical staples. It will be covered with a bandage and a tube may be placed under your skin to drain away any excess fluid. The bandage will usually need to be kept in place for a few days to reduce the risk of infection.

Recovering after an amputation

After surgery, you'll usually be given oxygen through a mask and fluids through a drip for the first few days while you recover on the ward.

A small flexible tube (a urinary catheter ) may be placed in your bladder during surgery to drain away urine. This means you won't need to worry about going to the toilet for the first few days after surgery.

The site of the operation may be painful, so you'll be given painkillers if you need them. Tell a member of your care team if the painkillers aren't working, as you may need a larger dose or a stronger painkiller. A small tube may be used to deliver local anaesthetic to the nerves in your stump to help reduce pain.

Your physiotherapist will teach you some exercises to help prevent blood clots and improve your blood supply while you're recovering in hospital.

Compression garments

You'll notice swelling ( oedema ) of your stump after surgery. This is normal and it may continue after you've been discharged.

Using a compression garment will help with swelling and the shape of the stump. It may also reduce phantom pain and help support the limb.

You'll be fitted with a compression garment once your wound has healed. It should be worn every day, but taken off at bedtime. You should be given at least two garments, which should be washed regularly.

Rehabilitation

Physical rehabilitation is an important part of the recovery process. It can be a long, difficult and frustrating process, but it's important to persevere. After rehabilitation, you should be able to return to work and other activities.

Your rehabilitation programme will be tailored to your individual needs and requirements, and will aim to allow you to carry out as many of your normal activities as possible.

You'll work closely with physiotherapists and occupational therapists who will discuss with you what you'd like to achieve from rehabilitation so that some realistic goals can be set.

Your rehabilitation programme will usually start within a few days of surgery, beginning with some simple exercises you can do while lying down or sitting. If you've had a leg amputation, you'll be encouraged to move around as soon as possible using a wheelchair.

You'll also be taught "transfer techniques" to help you move around more easily, such as how to get into a wheelchair from your bed.

Once your wound has started to heal, you may start working on an exercise programme with a physiotherapist in the hospital gym to help you maintain your mobility and muscle strength.

If you have a prosthetic limb fitted (see below), your physiotherapist will teach you how to use it – for example, how to walk on a prosthetic leg or grip with a prosthetic hand.

Going home and follow-up

The length of time it will take before you're ready to go home will depend on the type of amputation you've had and your general state of health.

Before you're discharged from hospital, an occupational therapist may arrange to visit you at home to see whether your home environment needs to be adapted to make it more accessible.

For example, you may need a wheelchair ramp or a stairlift. If these types of modifications are required, the issue can be referred to your local social services department. Read about mobility, wheelchairs and scooters and assessing your care and support needs .

It can take several months before you're fitted with a prosthetic limb (if you're a suitable for one), so you may be given a wheelchair to help you get around if you've had a lower limb amputation.

You'll probably need to attend a follow-up appointment a few weeks after being discharged to discuss how well you're coping at home and whether you require additional help, support or equipment.

At your appointment, you may also be given details of your nearest amputee support group, made up of both healthcare professionals and people living with an amputation.

Prosthetics

After an amputation, you may be able to have a prosthetic limb fitted.

Prosthetic limbs aren't suitable for everyone who's had an amputation because an extensive course of physiotherapy and rehabilitation is required (see below).

Adjusting to life with a prosthetic limb takes a considerable amount of energy because you have to compensate for the loss of muscle and bone in the amputated limb.

This is why frail people or those with a serious health condition, such as heart disease , may not be suitable for a prosthetic limb.

If you're able to have a prosthetic limb, the type of limb that's recommended for you will depend on:

  • the type of amputation you had
  • the amount of muscle strength in the remaining section of the limb
  • your general state of health
  • tasks the prosthetic limb will be expected to perform
  • whether you want the limb to look as real as possible or whether you're more concerned with function

If it's thought that you would find it difficult to withstand the strain of using a prosthetic limb, a purely cosmetic limb may be recommended. This is a limb that looks like a real limb, but can't be used.

It's possible to have a prosthetic limb that's both physically realistic and functional, but there may have to be an element of compromise between the two.

Preparing to have a prosthetic limb fitted

If a prosthetic limb is suitable for you, you'll begin a programme of activities while still in hospital to prepare for the prosthetic.

Before a prosthetic limb is fitted, the skin covering your stump may be made less sensitive (known as desensitisation). This will make the prosthetic more comfortable to wear.

Skin desensitisation involves the following steps:

  • gently tapping the skin with a face cloth
  • using compression bandages to help reduce swelling and prevent a build-up of fluid inside and around your stump
  • rubbing and pulling the skin around your bone to prevent excessive scarring

Your physiotherapist will teach you a range of exercises to strengthen the muscles in your remaining limb and improve your general energy levels, so you're able to cope better with the demands of an artificial limb.

Depending on what's available in your local area, it can be several months before you get your first appointment with a prosthetist (specialist in prosthetic limbs).

Stump care

It's very important to keep the skin on the surface of your stump clean to reduce the risk of it becoming irritated or infected.

Gently wash your stump at least once a day (more frequently in hot weather) with mild unscented soap and warm water, and dry it carefully.

If you have a prosthetic limb, you should also regularly clean the socket using soap and warm water.

When taking a bath, avoid leaving your stump submerged in water for long periods because the water will soften the skin on your stump, making it more vulnerable to injury.

If your skin becomes dry, use a moisturising cream before bedtime or when you're not wearing your prosthesis.

Some people find wearing one or more socks around their stump helps absorb sweat and reduces skin irritation. The size of your stump may change as the swelling goes down, so the number of socks you need to use may vary. You should change the socks every day.

Check your stump carefully every day for signs of infection, such as:

  • warm, red and tender skin
  • discharge of fluid or pus
  • increasing swelling

Contact your care team for advice if you think you may be developing a skin infection.

Caring for your remaining limb

After having a leg or foot amputated, it's very important to avoid injuring your remaining "good" leg and foot, particularly if your amputation was needed because of diabetes . Your remaining leg and foot may also be at risk.

Avoid wearing poorly fitting footwear and ensure that an appropriately trained healthcare professional, such as a podiatrist, is involved in the care of your remaining foot. You should also be offered a regular review of your foot by the foot care team.

Complications

Like any type of surgery, an amputation carries a risk of complications. It also carries a risk of additional problems directly related to the loss of a limb.

There are a number of factors that influence the risk of complications from amputation, such as your age, the type of amputation you've had, and your general health.

The risk of serious complications is lower in planned amputations than in emergency amputations.

Complications associated with having an amputation include:

  • heart complications – such as heart attack
  • deep vein thrombosis (DVT)
  • slow wound healing and wound infection
  • pneumonia
  • stump and "phantom limb" pain

In some cases, further surgery may be needed to correct problems that develop or to help relieve pain. For example, if neuromas (thickened nerve tissue) are thought to be causing pain, the affected cluster of nerves may need to be removed.

Stump and "phantom limb" pain

Many people who have an amputation experience some degree of stump pain or "phantom limb" pain.

Phantom limb sensations are sensations that seem to be coming from the amputated limb. Occasionally, these can be painful (phantom limb pain).

The term "phantom" doesn't mean the painful symptoms are imaginary. Phantom limb pain is a real phenomenon, which has been confirmed using brain imaging scans to study how nerve signals are transmitted to the brain.

The symptoms of phantom limb pain can range from mild to severe. Some people have described brief "flashes" of mild pain, similar to an electric shock, that last for a few seconds. Others have described constant severe pain.

Stump pain can have many different causes, including rubbing or sores where the stump touches a prosthetic limb, nerve damage during surgery and the development of neuromas.

Treating stump and phantom limb pain

Stump and phantom limb pain will usually improve over time, but treatments are available to help relieve the symptoms.

Medications

Medications that may be used to help relieve pain include:

Self-help measures and complementary therapy

There are several non-invasive techniques that may help relieve pain in some people. They include:

  • checking the fit of your prosthesis and making adjustments to make it feel more comfortable
  • applying heat or cold to your limb, such as using heat or ice packs, rubs and creams
  • massage – to increase circulation and stimulate muscles
  • acupuncture – thought to stimulate the nervous system and relieve pain
  • transcutaneous electrical nerve stimulation (TENS) – where a small, battery-operated device is used to deliver electrical impulses to the affected area of your body, to block or reduce pain signals
  • mental imagery (see below)

Research has shown that people who spend 40 minutes a day imagining using their phantom limb, such as stretching out their "fingers" or bunching up their "toes", experience a reduction in pain symptoms.

This may be related to the central theory of phantom limb pain (that the brain is looking to receive feedback from the amputated limb), and these mental exercises may provide an effective substitution for this missing feedback.

Another technique, known as mirror visual feedback, involves using a mirror to create a reflection of the other limb. Some people find that exercising and moving their other limb can help relieve the pain from a phantom limb.

Psychological impact of amputation

The loss of a limb can have a considerable psychological impact. Many people who've had an amputation report feeling emotions such as grief and bereavement, similar to experiencing the death of a loved one.

Coming to terms with the psychological impact of an amputation is therefore often as important as coping with the physical demands.

Having an amputation can have a considerable psychological impact for three main reasons:

  • you have to cope with the loss of sensation from your amputated limb
  • you have to cope with the loss of function from your amputated limb
  • your sense of body image, and other people's perception of your body image, has changed

Negative thoughts and emotions are common after an amputation. This is particularly true in people who've had an emergency amputation because they don't have time to mentally prepare for the effects of surgery.

Common negative emotions and thoughts experienced by people after an amputation include:

  • depression
  • anxiety
  • denial (refusing to accept that they need to make changes, such as having physiotherapy , to adapt to life with an amputation)
  • grief
  • feeling suicidal

People who've had an amputation as a result of trauma (particularly members of the armed forces) also have an increased risk of developing post-traumatic stress disorder (PTSD) .

Talk to your care team about your thoughts and feelings, particularly if you're feeling depressed or suicidal. You may need additional treatment, such as antidepressants or counselling , to improve your ability to cope after having an amputation.

Help and support

Being told you need to have a limb amputated can be a devastating and frightening experience. Adjusting to life after an amputation can be challenging, but many people enjoy a good quality of life once they have managed to adapt.
