Final answer:
Common methods of limb suspension in prosthetics are vacuum suspension, pin lock suspension, sleeve suspension, and suction suspension.
Step-by-step explanation:
Common methods of limb suspension in prosthetics include vacuum suspension, pin lock suspension, sleeve suspension, and suction suspension.
Vacuum Suspension:
This method uses a vacuum-sealed socket that creates a suction effect to secure the prosthetic limb to the residual limb. It provides good suspension and reduces pistoning (up and down movement) of the limb within the socket.
Pin Lock Suspension:
This method involves a pin that locks the prosthetic limb into place. The pin is inserted into a locking mechanism on the socket, providing secure suspension and preventing rotational movement.
Sleeve Suspension:
This method utilizes a prosthetic sleeve that fits snugly over the residual limb, creating friction and suction to hold the limb in place. It is particularly useful for individuals with short residual limbs or sensitive skin.
Suction Suspension:
This method uses a suction cup or liner that attaches to the residual limb, creating suction and maintaining suspension. It is commonly used in below-knee prosthetics.
