Losing a hand or an arm is life-changing, but the right prosthetic can restore function and independence. With advancements in prosthetic technology, people with upper limb amputations now have access to highly functional and comfortable solutions that can help them regain control over their daily lives.
However, choosing the best prosthetic depends on the level of amputation. Not all prosthetics work the same way, and what’s ideal for one person may not be suitable for another. Whether the amputation is at the fingers, wrist, or above the elbow, selecting the right device ensures better comfort, mobility, and usability.
Understanding the Different Levels of Upper Limb Amputation
Before choosing the right prosthetic, it’s important to understand the different types of upper limb amputations.
The level of amputation determines which muscles, joints, and bone structures remain, which affects the type of prosthetic that will work best.
A partial hand amputation involves the loss of fingers or part of the palm, while a wrist disarticulation means the hand is completely absent, but the forearm is intact.
Below-the-elbow amputations remove part of the forearm, but the elbow remains functional.
Above-the-elbow amputations extend higher, sometimes removing part of the upper arm or shoulder, making prosthetic control more complex.
Each level of amputation presents unique challenges, but prosthetic technology has advanced to provide customized solutions.
Whether someone needs a basic functional hand for gripping or an advanced bionic prosthetic with sensory feedback, there are options designed to meet different needs.
Prosthetic Solutions for Partial Hand Amputation
For individuals who have lost one or more fingers but still have a functioning palm and wrist, partial hand prosthetics can restore grip and hand function.
The right prosthetic depends on how many fingers are missing and how much mobility remains in the hand.
Silicone prosthetic fingers provide a natural look and help with simple activities like pushing buttons or stabilizing objects.
They don’t have active movement but can assist with daily tasks. Mechanical finger prosthetics offer more functionality by allowing users to bend and grip objects using remaining hand motion.
These are useful for people who need more precise control for activities like writing or holding tools.
For a more advanced option, bionic fingers powered by small motors can move independently based on muscle signals.
These devices allow for more natural movements and improve dexterity. They are particularly beneficial for users who need fine motor control for tasks like typing or playing musical instruments.
