Upper Extremity Prosthesis

Upper Extremity Prosthesis

An Upper Extremity Prosthesis is a type of artificial limb designed to replace a missing or amputated upper limb, which includes the arm, forearm, and hand. These prosthetic devices are meticulously crafted to replicate the appearance and functionality of a natural arm and hand, allowing individuals who have experienced limb loss to regain independence and perform various tasks.

• Transradial (Below-the-Elbow) Prosthesis:

This type is designed for individuals who have had an amputation below the elbow. It typically consists of a socket that fits over the residual limb, an elbow joint for added flexibility, and a hand or terminal device that can have various functions, such as grasping objects or performing fine motor tasks.

• Transhumeral (Above-the-Elbow) Prosthesis

individuals with amputations above the elbow. They include a socket, an elbow joint, and a more complex terminal device or hand that aims to replicate natural arm movement and dexterity.

• Shoulder Disarticulation or Forequarter Prosthesis

For individuals with amputations at or through the shoulder joint, these prostheses are designed to replace the entire arm, including the shoulder. They are highly customized and usually feature additional components to mimic the natural range of upper limb motion.

• Myoelectric Prosthesis

Some upper extremity prostheses incorporate myoelectric technology, which uses muscle signals from the residual limb to control the movement of the prosthesis. This allows for more natural and intuitive control.

The specific design and features of an upper extremity prosthesis are highly individualized, and prosthetists work closely with patients to ensure a proper fit and function. Advanced materials, such as lightweight and durable plastics and composites, are often used in these prosthetic limbs to improve comfort and functionality.

In addition to basic prosthetic arms and hands, specialized attachments can be added, such as adaptive tools or sports-specific attachments for activities like rock climbing, cycling, or swimming. The goal of upper extremity prostheses is to enhance the quality of life and enable individuals to engage in a wide range of daily activities, from self-care to recreational pursuits.
