Prosthetics

Prosthetics refers to the field of medicine that deals with the design, manufacture, and fitting of artificial devices, known as prostheses, to replace or support a missing or damaged body part.

Types of Prosthetics

• Lower Limb Prosthetics: These include prosthetic legs, feet, and ankles, designed to restore mobility and function in individuals with amputations below the knee or above the knee.
• Upper Limb Prosthetics: These include prosthetic arms, hands, and fingers, designed to restore function and mobility in individuals with amputations above the elbow, below the elbow, or at the shoulder.
• Dental Prosthetics: These include artificial teeth, dentures, and other oral appliances designed to replace missing teeth or support dental structures.
• Ocular Prosthetics: These include artificial eyes and orbital prostheses designed to restore appearance and function in individuals with eye loss or damage.
• Facial Prosthetics: These include artificial facial features, such as noses, ears, and cheeks, designed to restore appearance and function in individuals with facial defects or injuries.

Prosthetic Components

A prosthetic device typically consists of several components, including:

• Sockets: The interface between the prosthetic device and the residual limb, designed to provide a comfortable and secure fit.
• Liners: A cushioning layer that fits between the socket and the residual limb, helping to reduce friction and discomfort.
• Suspension systems: Mechanisms that help to suspend the prosthetic device from the body, such as straps, harnesses, or suction sockets.
• Control systems: Electronic or mechanical systems that allow the user to control the movement and function of the prosthetic device.
• Terminal devices: The distal end of the prosthetic device, such as a prosthetic hand or foot, designed to perform specific functions.

Prosthetic Materials

Prosthetic devices can be made from a variety of materials, including:

• Plastics: Lightweight and durable, often used for prosthetic sockets and liners.
• Metal alloys: Strong and corrosion-resistant, often used for prosthetic frames and components.
• Carbon fiber: Lightweight and strong, often used for prosthetic limbs and components.
• Silicone: Flexible and durable, often used for prosthetic liners and skin tones.

Prosthetic Fitting and Training

The process of fitting and training with a prosthetic device typically involves:

• Initial consultation: An evaluation by a prosthetist to determine the individual's needs and goals.
• Casting and molding: The creation of a mold or cast of the residual limb, used to design and fabricate the prosthetic socket.
• Prosthetic fabrication: The creation of the prosthetic device, including the socket, liner, suspension system, control system, and terminal device.
• Fitting and adjustment: The process of fitting the prosthetic device to the individual, making any necessary adjustments for comfort and function.
• Training and rehabilitation: Instruction and practice in using the prosthetic device, including exercises and activities to improve mobility and function.

Prosthetic Maintenance and Repair

Regular maintenance and repair of a prosthetic device is essential to ensure optimal function and longevity.

• Cleaning and disinfection: Regular cleaning and disinfection of the prosthetic device to prevent infection and damage.
• Inspection and adjustment: Regular inspection of the prosthetic device, making any necessary adjustments for fit and function.
• Repair and replacement: Repair or replacement of damaged or worn components, as needed.
