Prosthetics for amputation

When it comes to prostheses for different types of amputations, the specific type of prosthetic device will depend on the level and location of the amputation. Here are some common types of prostheses for different types of amputations: finger prostheses, partial hand prostheses, arm prostheses, leg prostheses, etc.

It’s important to note that the specific type of prosthetic device used will depend on factors such as the individual’s functional needs, activity level, and personal preferences. A consultation with a prosthetist is essential to determine the most appropriate prosthetic solution for each individual case.

Finger prostheses:

Finger prostheses are designed to replace amputated fingers. They can be custom-made to match the appearance and function of the missing finger.

Finger prostheses can be made from materials such as silicone or plastic and are typically attached to the remaining part of the hand using various methods, including adhesive or suction.

Partial hand prostheses:

Partial hand prostheses are designed to replace a portion of the hand that has been amputated, such as the fingers and/or palm. These prostheses can help with gripping and grasping objects and can be custom-made to fit the individual’s specific needs and functional requirements.

Below-Knee prostheses:

Below-knee prostheses, also known as transtibial prostheses, are designed to replace a lower leg amputation below the knee joint. They typically consist of a socket that fits over the residual limb, a pylon for support, and a foot component.

Below-knee prostheses can vary in design and materials based on the individual’s activity level and functional needs.

Above-Knee prostheses:

Above-knee prostheses, also known as transfemoral prostheses, are designed to replace a leg amputation above the knee joint. They typically consist of a socket, a knee joint mechanism, a pylon, and a foot component.

Above-knee prostheses are more complex than below-knee prostheses because they require a knee joint mechanism to enable walking and other activities.

Arm prostheses:

Arm prostheses are designed to replace all or part of an amputated arm. They can range from simple cosmetic devices to more advanced myoelectric prostheses that use muscle signals to control movement. Arm prostheses can assist with activities such as grasping objects, lifting, and performing fine motor tasks.

Prosthesis designed

Body powered:

This is where the body controls the prosthetic. For instance, a cable may move from one shoulder to the prosthetic hand, so the prosthetic activates as you move your shoulder.

Motor powered:

These prosthetics have buttons to control movement. A prosthetic hand, for example, may have a specific button to articulate wrists and fingers for gripping objects.

Myoelectric powered:

This new technology allows for the powering of prosthetic limbs by electrical signals sent via electrodes placed on the skin.

Artificial limbs attach to the amputee’s residual limb (stump) by belts, cuffs, or suction. Either the residual limb fits directly into a socket on the prosthetic, or a liner is used that’s fixed to the socket by vacuum or a pin lock.
