What are the parts of a prosthetic limb?

Prosthetic limbs are the artificial replacements for missing body parts. They are designed to help improve the quality of life and mobility for individuals who have lost a limb. Let's break down the various parts of a prosthetic limb in a step-by-step manner.

### 1. Socket.

The socket is the part of the prosthetic limb that attaches to the residual limb of the amputee. It is custom-made to fit each individual's unique limb shape and size, providing a comfortable and secure fit.

### 2. Interface.

The interface is the component that comes into direct contact with the skin of the residual limb. It helps to distribute pressure evenly and reduce skin irritation, providing a comfortable experience for the user.

### 3. Pylon.

The pylon is the internal support structure of the prosthetic limb, usually made of durable materials like carbon fiber or aluminum. It provides stability and strength to the limb, allowing the user to walk or perform daily activities with ease.

### 4. Joint.

The joint is the articulating mechanism that allows for movement in the prosthetic limb. Depending on the type of limb (e.g., arm or leg), various joints may be incorporated to mimic natural movement and functionality.

### 5. Foot/Hand.

The foot or hand is the end-effector of the prosthetic limb, providing support and balance for walking or gripping objects. Prosthetic hands can be customized with different grips and attachments to perform various tasks.

### 6. Covering.

The covering of the prosthetic limb is the outer cosmetic layer that gives the limb a natural appearance. It can be made of silicone, foam, or other materials to match the skin tone and texture of the user, helping to improve aesthetic appeal.

## Conclusion.

Each part of a prosthetic limb plays a crucial role in providing functionality, comfort, and aesthetics for the user. By understanding the components of a prosthetic limb, we can appreciate the complexity and precision required to create these life-changing devices.
