Definition and Medical Overview
A bilateral below knee amputation, or a bilateral transtibial amputation, is a big surgery. It needs a team of doctors from different fields. This surgery removes both legs below the knee. It’s a complex procedure that looks at many medical, mental, and social factors.
Terminology and Classification
Amputation terms can be tricky. There are many types and classifications. For example, Pyrogoff, Boyd, and Syme amputations are common ankle disarticulations. The Van Nes rotation, or rotationplasty, is a rare major amputation. It rotates the foot to make the ankle work like a knee.
It’s important for doctors and patients to know these terms. This helps in clear communication about the surgery and care after it.
Anatomical Structures Involved
The surgery affects the tibia, fibula, and soft tissues around them. The goal is to save as much tissue as possible. This helps with healing and getting ready for prosthetics.
This surgery is complex. It needs a skilled team and a good plan for care after surgery. The table below shows important details about bilateral below knee amputation.
Aspect | Description |
Terminology | Bilateral transtibial amputation, BK amputee |
Anatomical Structures | Tibia, fibula, surrounding soft tissues |
Surgical Considerations | Preservation of viable tissue, residual limb preparation |
Prevalence and Epidemiology
It’s key to know how common bilateral below knee amputations (BKA) are. This is because they greatly affect a person’s life and the care they need. It’s called double amputation legs.
Statistical Data on Bilateral BKA
Studies show that BKA often comes with health issues. For example, most patients with BKA have diabetes and high blood pressure. In fact, 86% of patients with BKA are diabetic, and 84% have high blood pressure. This shows why it’s vital to manage these conditions to avoid amputations.
In the U.S., amputations, including BKA, are a big health worry. From 1999, there were 14,420 non-fatal traumatic amputations. The U.S. Bureau of Labor Statistics found 6,200 work-related amputations in 2018. These numbers show how widespread the problem is.
Demographics and Risk Population
Who gets BKA? It often happens to older adults with long-term health issues. Conditions like PAD and diabetes make it more likely for someone to need BKA.
- Older adults are at higher risk due to the increased prevalence of chronic conditions.
- Diabetes and hypertension are major risk factors for bilateral BKA.
- Trauma, including work-related injuries, contributes to the incidence of amputations.
Knowing who is at risk helps doctors and nurses plan better. They can work harder to prevent BKA and help those who need it.
Primary Causes of Bilateral Below Knee Amputations
It’s important to know why people get bilateral below knee amputations. This surgery is often needed because of serious health problems.
Peripheral Arterial Disease
Peripheral arterial disease (PAD) is a big reason for these amputations. PAD blocks blood flow to the legs. This can cause a lot of pain and damage, leading to amputation if not treated.
Diabetes Mellitus Complications
Diabetes is also a major cause. It can damage blood vessels and nerves in the legs. This can lead to ulcers, infections, and amputation.
Trauma, Frostbite, and Burns
Trauma, frostbite, and burns can also cause amputations. Injuries can damage limbs too much. Frostbite and burns can harm tissues so much that surgery is needed.
Advantages of Below Knee vs. Above Knee Amputations
Keeping the knee joint during amputation boosts a patient’s mobility chances. Below knee amputations (BKA) make up over 50% of all major lower limb amputations each year. This shows their key role in medical care.
We’ll look at BKA’s benefits in function and energy use, comparing them to above knee amputations (AKA).
Functional Benefits of Knee Preservation
Keeping the knee joint is vital for post-amputation function. Knee preservation leads to more natural movement and better prosthetic control. This improves amputees’ quality of life.
- Improved prosthetic control
- Better stability and balance
- Enhanced mobility and walking ability
Research shows BKA patients have better rehab outcomes than AKA patients. The knee joint helps maintain a natural gait. This reduces the risk of back pain and joint problems in the remaining limb.
Energy Expenditure and Mobility Outcomes
Walking energy use is key for amputees’ mobility. Studies show walking energy cost goes up with more proximal amputations. AKA patients use more energy walking than BKA patients.
This energy difference is important. It affects amputees’ daily activity ability and independence. Lower energy expenditure in BKA means patients can walk longer without getting tired. This boosts their mobility and life quality.
- Reduced energy expenditure during walking
- Improved mobility and independence
- Better overall rehabilitation outcomes
In summary, below knee amputations have many benefits over above knee amputations. They offer better function and energy use. Preserving the knee joint helps patients achieve better mobility and life quality.
Pre-Surgical Evaluation and Planning
Pre-surgical evaluation and planning are key to successful bilateral below knee amputation (BKA) surgeries. It’s important to assess and prepare patients well. This ensures the best surgical results and a smoother recovery.
Multidisciplinary Assessment Process
A thorough pre-surgical evaluation is a team effort. Vascular surgeons, rehabilitation specialists, and others work together. They assess the patient’s health and plan the surgery.
The evaluation includes several steps:
- Medical history review
- Physical examination
- Imaging studies (e.g., X-rays, MRI)
- Vascular assessment
- Rehabilitation evaluation
This team approach helps create a personalized surgical plan. It meets the unique needs of each patient with bilateral BKA.
Assessment Component | Description | Importance in Bilateral BKA |
Medical History Review | Examining the patient’s past medical conditions and surgeries | High |
Physical Examination | Assessing the patient’s current physical condition | High |
Imaging Studies | Using X-rays, MRI, or other imaging techniques to evaluate the affected limbs | Critical |
Vascular Assessment | Evaluating blood flow to the affected areas | Critical |
Patient Preparation and Informed Consent
Patient preparation is vital. We make sure patients understand their condition, the surgery, and what to expect. This includes discussing risks and benefits and the rehabilitation process.
We get informed consent by explaining the plan and answering questions. This builds trust and a strong relationship between the patient and the healthcare team.
By focusing on detailed pre-surgical evaluation and planning, we improve outcomes for BKA patients. This careful approach ensures high-quality care that meets each patient’s needs.
Surgical Procedure and Techniques
The surgery for bilateral below knee amputations (BKA) is very detailed. It needs careful planning and precise steps. We will explain the main parts of this surgery, focusing on the standard methods used to make the best residual limb.
Standard Surgical Approach
The surgery for bilateral BKA has several key steps. First, the supplying artery and vein are ligated to stop bleeding and keep the area clean. Then, the muscles are transected at a level that ensures the best stump length and muscle balance. Lastly, the bone is sawed through, usually at a level that covers the stump well with soft tissue and fits the prosthetic.
Residual Limb Optimization
To make a stable and useful residual limb, we use myodesis and myoplasty. Myodesis attaches muscles directly to the bone, while myoplasty sutures muscles together. These methods help stabilize the residual limb and improve prosthetic fitting by creating a more controlled and balanced stump.
Optimizing the residual limb greatly improves patient outcomes. It leads to better mobility and less chance of complications. Our aim is to make a residual limb that supports effective prosthetic use. This helps patients regain independence and mobility.
Post-Operative Care and Management
The time after surgery for bilateral below knee amputations is very important. We need to manage pain, stop infections, and start rehab to help patients recover well.
Immediate Recovery Phase
In the first days after surgery, watching for problems like infection, bleeding, or open wounds is key. Rigid removable dressings help wounds heal faster and reduce problems in trans-tibial amputations. We keep a close eye on patients for any signs of these issues.
Pain Management Strategies
Managing pain is a big part of caring for patients after surgery. We use different ways to help with pain, like medicine and other methods. A study found that
“Pain management in amputees requires a complete plan to handle both short-term and long-term pain.”
Pain Management Strategy | Description | Benefits |
Pharmacological Interventions | Use of medicines to control pain | Works well for short-term pain |
Alternative Therapies | Non-medical ways like physical therapy and relaxation techniques | Lessens need for medicine, boosts overall health |
We take a full approach to care after surgery. This includes using rigid removable dressings and a mix of pain management methods.
