What are the 4 Types of Prosthetics?
Prosthetics are life-changing devices designed to restore mobility, independence, and quality of life after limb loss. They are generally classified into four main types of Prosthetics based on the level of amputation: transradial, transhumeral, transtibial, and transfemoral prosthetics.
Each type is tailored to meet specific functional needs and challenges, helping individuals return to daily activities, work, and recreation.
What are the 4 Types of Prosthetics?
1. Transradial Prosthetics (Below-Elbow)
Definition: Transradial prosthetics are used when an amputation occurs below the elbow.
Function: They restore wrist, hand, and finger movement, allowing people to complete essential tasks like eating, writing, and dressing.
Common Components:
-
Myoelectric hands that respond to muscle signals
-
Hook devices for strength and precision
-
Cosmetic hands designed for appearance
Benefits: Easier to learn compared to above-elbow devices, they help users achieve greater independence in everyday activities.

2. Transhumeral Prosthetics (Above-Elbow)
Definition: Transhumeral prosthetics are required after amputations above the elbow.
Function: They replace elbow, wrist, and hand function, making them more complex than below-elbow prosthetics.
Common Components:
-
Artificial elbows (manual, powered, or hybrid)
-
Myoelectric or body-powered hand systems
Benefits: Restores a wider range of motion and enables users to complete daily tasks that require bending, lifting, and reaching.
3. Transtibial Prosthetics (Below-Knee)
Definition: Transtibial prosthetics are for amputations below the knee, where the knee joint remains intact.
Function: These prosthetics restore walking ability and balance while preserving natural knee movement.
Common Components:
-
A custom prosthetic socket
-
Lightweight pylon
-
Prosthetic foot (energy-storing, dynamic, or microprocessor-controlled)
Benefits: Users often achieve higher mobility compared to above-knee prosthetics, with less energy required for walking.
4. Transfemoral Prosthetics (Above-Knee)
Definition: Transfemoral prosthetics are used for amputations above the knee.
Function: They replace both knee and foot function.
Common Components:
-
Prosthetic knees (manual lock, hydraulic, or microprocessor)
-
Prosthetic feet matched to the patient’s activity level
Benefits: Supports walking, stair climbing, and community mobility. Newer microprocessor knees increase stability and help prevent falls.
Choosing the Right Prosthetic
The right prosthetic depends on several factors, including:
-
Level of amputation
-
Activity level (K-level assessment)
-
Lifestyle goals
-
Insurance coverage
Working with a prosthetist ensures the device is properly fitted and aligned for maximum comfort and function.
