forearm prosthesis的意思|示意

Forearm prosthesis，or forearm replacements, can be used to restore muscle, tendon and other tissues that have been damaged or lost due to trauma, infection or disease. Forearm prostheses can be used in conjunction with or in place of amputation.

Forearm prostheses are typically composed of three components: an artificial skin covering, a socket which attaches to the user’s residual limb and a frame which supports and holds the socket in place. The socket is where the user’s residual limb sits and is custom designed to fit their anatomy and provide maximum stability. The frame, which is either made from metal or plastic, is attached to the socket and provides support and rigidity.

Forearm prostheses are often used to replace a hand or wrist that has been lost due to trauma, infection or disease. They can also be used for upper limb amputees who still have some residual movement in their shoulder. In these cases, the forearm prosthesis is used to replace the missing forearm and wrist, and the shoulder prosthesis is used to restore some functionality and movement in the shoulder.

Forearm prostheses can be used for both functional and cosmetic purposes. This means they can be used to restore movement in the user’s arm, to enhance the appearance of their limb and to provide extra support and stability. For example, some forearm prostheses are designed with a built-in elbow joint to enable the user to flex and extend their arm.

There are different types of forearm prostheses available, depending on the individual’s needs and the level of functionality they require. Some of these include myoelectric prostheses, which use electrical signals emitted by the user’s residual muscles to control the prosthetic hand or wrist; body-powered systems, which use harnesses or cable systems to control the movement of the prosthetic; and passive prostheses, which do not require the user to use their own muscles to control the device.

Forearm prostheses can be an effective solution for those who have lost an arm or part of an arm. They can provide functional and cosmetic benefits, enabling the user to live a life that is as close to normal as possible.
