Arm Amputation

Understanding Upper Limb Amputations

Upper limb amputations refer to the removal of a portion of the arm, ranging from the fingers to the entire arm and shoulder. They can be categorized as either traumatic (due to an accident or a traumatic injury) or surgical (when performed due to medical reasons).

An automobile accident, gunshot wound, or a work-related accident may cause a traumatic amputation. Although traumatic amputations are often emergencies, planned amputations are generally part of a treatment plan designed to improve the patient’s overall quality of life.

Why Would an Amputation be Necessary?

There are several reasons why an upper limb amputation may be recommended. The most common medical conditions that might lead to amputation include severe trauma, cancer, life-threatening infections, and complications from diseases such as diabetes or blood vessel disease.

In some cases of surgical amputation, they may be necessary to stop the spread of infection, relieve unmanageable pain, or remove non-functioning soft tissue that cannot be salvaged. In certain situations, amputation may be a proactive measure to ensure long-term health and functionality.

What is Congenital Amputation?

Congenital amputation occurs when a child is born without part or all of a limb. This can happen due to factors such as genetic conditions, environmental factors during pregnancy, or unknown causes.

Unlike acquired amputations, congenital amputations involve the absence of a limb from birth. For these individuals, prosthetic limbs can be introduced to enhance mobility and independence as they grow.

Levels of Upper Extremity Amputations

Upper extremity amputations are classified based on the level at which the limb is removed. The level determines the type of prosthesis that may be needed and impacts the range of motion and function after surgery. Key levels include:

• Finger/Partial Hand Amputation: Involves removal of one or more fingers or parts of the hand while preserving some functionality.
• Wrist Disarticulation: The hand is removed while retaining the forearm, allowing for some rotational function.
• Below Elbow (Transradial) Amputation: The arm is removed below the elbow, leaving a portion of the forearm.
• Above Elbow (Transhumeral) Amputation: The amputation is performed above the elbow at the upper arm, impacting a greater portion of the arm.
• Shoulder Disarticulation and Forequarter Amputation: These are more extensive surgeries that involve the removal of the arm at or above the shoulder level, which can include parts of the shoulder blade and collarbone.

The level of amputation significantly influences the patient’s recovery process and the type of rehabilitation required.

Surgical Approaches to Amputation

Amputation surgeries aim to remove all damaged or diseased tissue while preserving as much of the limb as possible. Surgeons carefully consider the impact on mobility, sensation, and appearance, especially when a prosthetic will be part of rehabilitation. The goal is to ensure that the remaining limb is suitable for prosthetic fitting while prioritizing the patient’s comfort and functionality.

Common surgical approaches include:

Standard Amputation

In this procedure, the limb is removed, and the remaining muscles are anchored to the bone and covered with skin. For those requiring a prosthetic, the stump is shaped and padded to ensure a comfortable fit, preventing pain and complications like tissue breakdown.

Osseointegration (OI)

This advanced technique involves inserting a steel implant into the residual bone, providing a direct connection for a prosthetic. By transferring weight-bearing forces to the bone rather than soft tissue, OI allows for more natural movement and comfort, especially during standing and walking.

Recovery After Amputation

Proper wound care is essential for healing and preparing the limb for eventual prosthetic fitting. Patients may experience pain, swelling, and sensitivity, all of which need to be carefully managed to ensure a smooth recovery. The initial stages of healing focus on keeping the wound clean and preventing infection, while the later stages involve shaping the residual limb for optimal prosthetic use.

Scar management, desensitization exercises, and physical therapy are also key components of the recovery process. Physical therapy plays a crucial role in restoring strength, and range of motion, and learning to use adaptive equipment or prosthetics. Mental health support is equally important, as the emotional impact of an amputation can be significant.

Managing Nerve Pain After Amputation

One challenge many patients face after amputation is nerve pain, including neuromas, which occur when nerve endings at the site of amputation form painful growths. This condition can lead to significant discomfort, often described as sharp or electric-like sensations at the residual limb.

Neuroma Excision

Neuroma excision involves surgically removing these painful nerve endings. During the procedure, surgeons address the irritated nerves to reduce or eliminate the source of pain. In some cases, the nerve is redirected or buried within muscle tissue to decrease the likelihood of neuroma recurrence further.

Targeted Muscle Reinnervation (TMR)

TMR is an advanced technique to reduce post-amputation nerve pain and improve prosthetic control. Surgeons redirect severed nerves to nearby muscles, allowing them to reinnervate. This not only helps alleviate pain by preventing neuroma formation but also enhances the ability to control advanced prosthetic limbs by harnessing natural nerve signals.

These specialized surgical treatments provide patients with options to address nerve pain, improving their quality of life and overall recovery experience. When combined with tailored rehabilitation, these treatments play a crucial role in optimizing outcomes for amputation patients.
