Plunger pins are used in prosthetic suspension systems to help secure a prosthetic limb to the residual limb. They work with a locking liner system, where a liner with an embedded pin is rolled onto the residual limb, and the pin clicks into a locking mechanism inside the prosthetic socket.
This system provides a secure fit, prevents unwanted movement, and allows for easy donning and doffing of the prosthesis.
