Prosthetic devices have come a long way in the past few decades. The advancements in technology have allowed for the development of various types of prosthetic devices that are more comfortable, effective, and affordable. In this article, we will provide a guide to the different types of prosthetic devices available in the market for patients.
- Upper Limb Prostheses
Upper limb prostheses are designed for individuals who have lost one or both arms. They come in a variety of designs, including body-powered prostheses, myoelectric prostheses, and hybrid prostheses.
Body-powered prostheses work by using a cable that connects the prosthetic device to the body harness. The wearer uses their shoulder or upper body movements to control the prosthetic hand or arm.
Myoelectric prostheses, on the other hand, use electrodes to pick up the electrical signals generated by the muscles in the residual limb. These signals are then translated into the movement of the prosthetic hand or arm.
Hybrid prostheses combine the best of both worlds. They use both the body-powered and myoelectric systems, allowing the wearer to control the prosthetic device using either method.
- Lower Limb Prostheses
Lower limb prostheses are designed for individuals who have lost one or both legs. They come in a variety of designs, including transtibial prostheses, transfemoral prostheses, and osseointegrated prostheses.
Transtibial prostheses are designed for individuals who have lost their lower leg, below the knee. They typically include a socket, foot, and ankle components.
Transfemoral prostheses are designed for individuals who have lost their upper leg, above the knee. They include socket, knee, and foot components.
Osseointegrated prostheses involve surgically implanting a metal post into the residual limb, which then attaches to the prosthetic device. This type of prosthesis is often more comfortable and stable than traditional prostheses.
- Prosthetic Feet and Ankles
Prosthetic feet and ankles are designed to mimic the natural movement of a foot and ankle. They come in a variety of designs, including energy-storing prosthetic feet, dynamic-response prosthetic feet, and microprocessor-controlled prosthetic feet.
Energy-storing prosthetic feet store energy during the stance phase of walking and release it during the push-off phase, providing a more natural gait.
Dynamic-response prosthetic feet are designed to respond to changes in terrain, providing greater stability and balance.
Microprocessor-controlled prosthetic feet use sensors and a computer to adjust the foot’s resistance and stiffness, providing a more natural gait and improved balance.
- Other Prosthetic Devices
Other prosthetic devices include prosthetic fingers and toes, facial prostheses, and breast prostheses. These devices are designed to help individuals who have lost limbs or body parts due to disease, injury, or surgery.
There are many different types of prosthetic devices available in the market for patients. It is important to work with a healthcare professional to determine which type of prosthesis is right for you based on your individual needs, lifestyle, and goals. With the right prosthetic device, individuals can regain their independence and enjoy a more fulfilling life.
