'''Limb amputations''' refer to the surgical removal of a limb, either partially or completely. This procedure is performed due to various reasons, including trauma, disease, or congenital conditions. Limb amputations can significantly impact an individual's physical and psychological well-being, requiring comprehensive medical care and rehabilitation.
'''Limb amputation''' is the surgical removal of a limb or part of a limb. It is a procedure that is performed for various medical reasons, including severe trauma, infection, malignancy, and vascular diseases. Amputations can also be congenital, where a limb is absent or underdeveloped at birth.


== Causes ==
==Indications==
Limb amputations can occur as a result of different causes. Traumatic amputations are often the result of accidents, such as motor vehicle collisions, industrial mishaps, or severe injuries during sports activities. These accidents can lead to the loss of a limb or the need for surgical intervention to remove a severely damaged limb.
Limb amputations are indicated in several clinical scenarios:


Disease-related amputations are commonly performed to manage conditions such as cancer, peripheral vascular disease, or severe infections. In some cases, individuals with congenital conditions, such as limb malformations or skeletal dysplasia, may require amputations to improve their quality of life or address functional limitations.
* '''[[Trauma]]''': Severe injuries from accidents, such as motor vehicle collisions or industrial accidents, can necessitate amputation when the limb is irreparably damaged.
* '''[[Peripheral artery disease]]''': Poor blood circulation due to narrowed arteries can lead to tissue death, requiring amputation.
* '''[[Diabetes mellitus]]''': Complications such as diabetic foot ulcers and infections can lead to the need for amputation.
* '''[[Malignancy]]''': Bone or soft tissue cancers may require amputation to prevent the spread of cancer.
* '''[[Infection]]''': Severe infections that do not respond to antibiotics may necessitate amputation to prevent systemic spread.
* '''[[Congenital limb deficiency]]''': Some individuals are born with missing or underdeveloped limbs, which may require surgical intervention.


== Diagnosis ==
==Types of Amputation==
The diagnosis of limb amputations involves a thorough physical examination and the use of imaging tests. During the physical examination, the healthcare provider assesses the affected limb, looking for signs of trauma, disease, or congenital abnormalities. They may also evaluate the individual's overall health and medical history to determine the most appropriate course of action.
Amputations can be classified based on the level of the limb that is removed:


Imaging tests, such as X-rays, computed tomography (CT) scans, or magnetic resonance imaging (MRI), may be ordered to provide detailed images of the affected limb. These tests help in assessing the extent of damage, identifying any underlying conditions, and planning the surgical procedure or prosthetic fitting.

  * [[Above-elbow amputation]]
  * [[Elbow disarticulation]]
  * [[Below-elbow amputation]]
  * [[Wrist disarticulation]]
  * [[Partial hand amputation]]


== Treatment ==
* '''[[Lower limb amputation]]''':
The treatment of limb amputations involves a multidisciplinary approach, including prosthetics, rehabilitation, and, in some cases, additional surgical interventions. The primary goal is to restore functionality and improve the individual's quality of life.

  * [[Above-knee amputation]]
  * [[Knee disarticulation]]
  * [[Below-knee amputation]]

Prosthetics play a crucial role in limb amputation rehabilitation. These artificial limbs are custom-made to fit the individual's residual limb and are designed to mimic the function of the lost limb. Prosthetic limbs can vary in complexity, ranging from basic designs for daily activities to advanced models for sports or specialized tasks.
==Surgical Procedure==
The surgical procedure for amputation involves several key steps:


Rehabilitation is an essential component of the treatment process. It includes physical therapy, occupational therapy, and psychological support. Physical therapy focuses on improving strength, flexibility, and mobility, while occupational therapy helps individuals regain independence in daily activities. Psychological support aims to address the emotional and psychological challenges associated with limb loss, promoting mental well-being and adjustment.
1. '''Anesthesia''': General or regional anesthesia is administered to the patient.
2. '''Incision and Dissection''': The surgeon makes an incision at the predetermined level and dissects through the skin, muscle, and other tissues.
3. '''Bone Cutting''': The bone is cut using a saw, and the edges are smoothed to prevent sharp edges.
4. '''Hemostasis''': Blood vessels are tied off or cauterized to prevent bleeding.
5. '''Closure''': The muscles and skin are sutured to create a stump that can accommodate a prosthesis.
6. '''Dressing and Bandaging''': The stump is dressed and bandaged to promote healing.


In some cases, additional surgical interventions may be required to optimize the outcome of limb amputations. These procedures may involve revision surgeries to improve the fit and function of prosthetic limbs, or reconstructive surgeries to address specific functional or cosmetic concerns.
==Postoperative Care==
Postoperative care is crucial for recovery and includes:


== Prognosis ==
* '''Pain management''': Medications are provided to manage pain, including [[opioids]] and [[non-steroidal anti-inflammatory drugs]] (NSAIDs).
The prognosis for individuals with limb amputations varies depending on various factors, including the cause of amputation, overall health, and access to medical care and rehabilitation services. With advancements in prosthetic technology and rehabilitation techniques, many individuals are able to regain a significant level of functionality and independence.
* '''Wound care''': Regular dressing changes and monitoring for signs of infection.
* '''Physical therapy''': Rehabilitation to strengthen remaining muscles and improve mobility.
* '''Prosthetic fitting''': Assessment and fitting for a prosthetic limb to aid in mobility.
* '''Psychological support''': Counseling and support groups to help with the emotional impact of limb loss.


However, it is important to note that limb amputations can have long-term physical and psychological effects. The adjustment process may involve challenges such as phantom limb pain, body image concerns, and emotional distress. Ongoing support from healthcare professionals, support groups, and loved ones is crucial in promoting overall well-being and successful adaptation.
==Complications==
Complications following amputation can include:
