There are different methods of suspension of the prosthesis.

They are: anatomical, suction, elevated vacuum, shuttle-lock (pin type) systems and lanyard systems.

  • Anatomical suspension utilizes the contour of the bony prominences of the residual limb to hold onto.
  • Suction system area used with either a cushion liner, with or without sealing bands, or direct skin contact of the residual lib. The socket has a a one way valve to expel the air out of the socket, which creates negative pressure in the socket to attain suspension.
  • The elevated vacuum system utilizes an external pump to draw the air out of the socket and obtain negative pressure inside of the socket to achieve suspension.
  • The shuttle lock system consist of a pin that is threaded to the distal end (bottom) of the liner, which then engages to the locking mechanism attached to the distal end of the socket to achieve suspension.
  • The lanyard system often used with transfemoral (above knee) prosthesis. It consists of wearing a liner, attached at the distal end of the liner is a Velcro strap or braided string. Then is is fed through the locking mechanism and pulled out of the bottom of the socket to obtain suspension.
