Amputation is the surgical removal of all or part of a limb, usually performed to save a patient's life. Amputations can be carried out under general anaesthetic or using an epidural or spinal anaesthetic, depending on the body part being amputated. The procedure may be necessary due to severe injury, infection, trauma, or complications related to underlying health conditions such as cancer, diabetes, or peripheral arterial disease (PAD). Following amputation, patients typically stay in the hospital for several days, receiving pain medication and antibiotics as needed. They are taught how to change their dressings and may begin physical therapy soon after surgery. The recovery process can be challenging, often requiring rehabilitation and emotional support to help patients adjust to their new physical state.

What You'll Learn
Amputation types: surgical, traumatic, congenital
Amputation is the removal of a limb or body part. It can be categorised into three types: surgical, traumatic, and congenital. Understanding the different types of amputations is essential for tailoring treatment plans to meet each patient's needs. Here is an overview of each type:
Surgical Amputation
Surgical amputation is a procedure where a part of the body is removed to address medical issues or prevent further complications. It is often a life-changing experience that significantly impacts a person's physical and emotional well-being. Surgical amputations can be necessary for various reasons, including:
- Vascular diseases and conditions affecting blood flow, such as diabetes and peripheral arterial disease (PAD).
- Preventing the spread of certain types of cancer, such as sarcomas affecting bone and soft tissue.
- Addressing tissue destruction, infection, or disease that endangers the person's life or makes repair impossible.
- Preventive surgery for athletes to relieve chronic pain or improve performance.
Traumatic Amputation
Traumatic amputation is the sudden and unexpected loss of a limb due to an accident or injury. It can occur in various settings, including vehicular accidents, workplace incidents, and military combat. Traumatic amputations can result in partial or total limb loss and create a dangerous situation due to blood loss. Immediate surgical intervention and aggressive rehabilitation may be required. Some common causes include:
- Motor vehicle accidents, including high-speed collisions and motorcycle accidents.
- Occupational or industrial accidents, such as injuries from a table saw blade.
- Combat injuries, including war injuries and acts of terrorism.
Congenital Amputation
Congenital amputation refers to the absence or incomplete formation of a limb or body part present at birth. It occurs due to developmental abnormalities or genetic factors. Children with congenital amputations may undergo surgery or be fitted with artificial limbs later in life, depending on their specific needs and the extent of bone and tissue damage. Genetic conditions such as Amelia, Holt-Oram syndrome, or Roberts syndrome can result in limb malformations or absence.

Anaesthesia options
Amputation is the surgical removal of all or part of a limb. It can be necessary in cases of severe injury, infection, trauma, or complications related to an underlying health condition such as cancer or diabetes.
Amputations can be performed under general anaesthesia or using an epidural or spinal anaesthetic. The choice of anaesthetic depends on the body part being amputated.
General Anaesthesia
General anaesthesia renders the patient unconscious during the procedure. This type of anaesthesia is often used for more complex or extensive amputations, such as those involving the removal of an entire limb.
Epidural Anaesthesia
Epidural anaesthesia involves injecting medication into the epidural space, located just outside the membrane covering the spinal cord. This numbs the lower half of the body, including the legs and torso, while allowing the patient to remain conscious. Epidural anaesthesia is commonly used for amputations below the waist, such as the removal of a toe, foot, or leg.
Spinal Anaesthesia
Spinal anaesthesia is similar to epidural anaesthesia in that it numbs the lower half of the body. However, the medication is injected directly into the spinal fluid, resulting in a more rapid onset of numbness. Spinal anaesthesia is often used for amputations that require a quick anaesthetic effect, such as emergency trauma cases.
Local Anaesthesia
Local anaesthesia involves injecting a numbing agent directly into the area surrounding the amputation site. While it does not provide the same level of numbness as the other anaesthesia options, it can be used in minor amputations or in conjunction with other anaesthesia methods to provide additional pain relief.
The choice of anaesthesia depends on various factors, including the patient's medical history, the extent of the amputation, and the patient's preference. In some cases, a combination of anaesthesia techniques may be used to ensure the patient's comfort and safety during the procedure.
It is important to note that the recovery process after amputation involves managing pain and adjusting to the physical and psychological changes associated with limb loss. Patients may experience phantom limb pain, emotional distress, and challenges with mobility and daily activities. Rehabilitation, including physical therapy and, in some cases, the use of prosthetic limbs, plays a crucial role in helping individuals adapt to their new circumstances.

Post-operative care: pain management, physiotherapy, occupational therapy
Post-operative care is a critical aspect of the recovery process after an amputation. It involves pain management, physiotherapy, and occupational therapy to help patients adjust to their new physical state and regain independence. Here are some key components of post-operative care:
Pain Management
The loss of a limb can result in continuing pain, including phantom limb pain, where individuals experience pain that seems to be coming from the missing limb. To manage this, patients are often advised to use compression garments, which help with swelling and can also reduce phantom pain. Additionally, anti-embolic and sequential compression hoses may be applied to enhance venous return and reduce the risk of thrombophlebitis. Low-dose anticoagulants may also be administered to prevent thrombus formation without increasing the risk of postoperative bleeding.
Physiotherapy
Physical rehabilitation is crucial for recovery. Physiotherapists teach patients exercises to improve blood supply and prevent blood clots during the initial recovery period in the hospital. These exercises can help reduce swelling (oedema) of the stump, which is a common occurrence after amputation surgery. Physiotherapy also focuses on improving muscle strength, flexibility, and coordination. For patients using prosthetics, physiotherapists provide training on how to use them effectively.
Occupational Therapy
Occupational therapy aims to help individuals regain independence and adapt to daily life, with or without a prosthetic. Occupational therapists work with patients to optimize their motor skills, particularly for those with arm prostheses, enabling them to perform daily activities more easily. They also assess the need for home modifications, such as installing a wheelchair ramp or stairlift, to ensure a safe and accessible living environment.
The recovery process for amputation patients is complex and often involves a multidisciplinary team of experts, including physiatrists, orthotists, prosthetists, physical and occupational therapists, and rehabilitation psychologists. This team works together to create a customized rehabilitation plan tailored to the patient's needs and goals.

Prosthetic limbs: types, fitting, and learning to use
Types of Prosthetic Limbs
Prosthetic limbs have come a long way since their early incarnations as wooden or iron limbs. Modern prosthetic limbs are designed to improve an individual's quality of life by providing movement and independence. Prosthetic limbs are typically divided into two categories: preparatory or temporary prosthetics, and definitive or permanent prosthetics.
Preparatory prosthetics are basic and temporary, designed for initial gait training. They help the residual limb stabilize in volume and shape and are usually worn for several months. Definitive prosthetics, on the other hand, are permanent solutions designed for long-term use. They incorporate more responsive components to help individuals achieve higher mobility goals.
Fitting Prosthetic Limbs
The fitting process for a prosthetic limb typically begins with the healing of the residual limb. Following amputation surgery, it is crucial to follow the surgeon's instructions, maintain wound cleanliness, and prevent infection. Once the surgical sutures are removed, a "shrinker sock", made from elastic material, is used to control swelling and provide compression to the residual limb.
After the wound has healed and swelling has decreased, usually within 3 to 6 weeks post-surgery, the process of prosthetic fitting commences. Plaster impressions and measurements are taken to determine limb volume, which guides the fabrication of a test socket. The test socket is a clear plastic mold of the residual limb, allowing the prosthetist to evaluate the fit and make necessary modifications.
Learning to Use Prosthetic Limbs
Learning to use a prosthetic limb can be challenging, and individuals often require the support of a dedicated team of experts, including physiatrists, prosthetists, physical therapists, and rehabilitation psychologists. Common issues that individuals may face include excessive sweating, which can impact the fit of the prosthesis and cause skin problems, as well as changes in the residual limb's shape and weakness in the limb, which can affect the usage of the prosthesis.
Phantom limb pain, experienced by about 80% of people with amputations, can also impact an individual's ability to use a prosthetic limb. It is crucial to have a customized rehabilitation plan to address these challenges and promote a successful transition to using a prosthetic limb.

Frequently asked questions
Amputation is the surgical removal of all or part of a limb. It is normally performed to save someone's life.
Amputation may be necessary in cases of severe injury, infection, trauma, or complications related to an underlying health condition like cancer or diabetes. The most common reason for amputation is poor blood flow.
Amputations can be done under general anaesthetic or using an epidural or spinal anaesthetic. Most amputations involve removing a section of a limb rather than the entire limb. After the amputation, the wound will be stitched up and sealed.
After an amputation, you will stay in the hospital for several days. You will be given instructions on how to change your dressing and medication to manage pain. You will also begin physical therapy soon after your surgery. Once you are discharged, you will likely need to attend a follow-up appointment a few weeks later to discuss how you are coping and whether you need additional help.
