A prosthetic leg connects to the residual limb (stump) using several methods.
Attachment Methods
The connection method focuses on securely and comfortably attaching the artificial limb to the body. Here's a breakdown of the primary ways a prosthetic leg connects:
-
Belts and Cuffs: This is an older method, though still sometimes used, where belts and cuffs are employed to strap the prosthetic limb to the residual limb.
-
Socket Connection: The residual limb fits into a socket on the prosthetic. This can be a direct fit, or more commonly, utilize a liner.
-
Liners and Locking Mechanisms: Modern prosthetic legs frequently use a liner that fits over the residual limb. This liner then attaches to the socket using one of the following methods, based on the reference:
- Vacuum (Suction Sockets): The liner creates a vacuum seal within the socket, holding the prosthetic securely.
- Pin Lock: A pin on the liner inserts into a locking mechanism within the socket.
Summary Table of Connection Methods
| Method | Description |
|---|---|
| Belts and Cuffs | Straps secure the prosthetic to the limb. |
| Direct Socket Fit | The residual limb fits directly into the prosthetic socket. |
| Suction Socket | A liner creates a vacuum within the socket, securing the prosthetic. |
| Pin Lock | A pin on the liner locks into a mechanism within the socket. |
