Style and fit will be unique to the person’s needs and activity level. There are many socket and suspension prosthetic systems available; each option will be discussed at length during your visit. At POSI, we encourage and welcome your participation in the design process. Our practitioners have experience working with a variety of socket designs for each level of amputation. Designs are chosen on an individual basis from information gathered during your initial evaluation.
This has the biggest impact on success in rehabilitation. Additionally, there is a correlation between proper fit and perceived weight. Well-fitting sockets should have increased proprioceptive feedback, anatomical control, decreased energy expenditure, total contact and most of all, it should be comfortable.
Closely related to the design of the socket is the suspension, or how the socket remains in place on the limb. Suspension mechanisms are incorporated as part of socket design and will be chosen prior to casting. Suspension can be achieved through these options:
Mechanical lock is achieved by the incorporation of a pin attached at the end of a liner which engages into a lock in the socket.
Suction Suspension Prosthetic
Suction suspensions are achieved through a number of methods including seal-in liners and direct skin contact.
Anatomical Suspension Prosthetic
Anatomical suspension is achieved when the contours of the socket capture and hold onto the contours of the patient’s body.
Symptoms of Poor Fitting Socket
- Unable to progress to expected goals
- Feels like a lot of effort and concentration to walk, increased energy expenditure
- Poor confidence/balance
- Skin breakdown, callus or unusual discoloration
- Significant space between residual limb and socket in standing position
- Inability to balance or transfer weight to prosthesis without fear or pain.
Socket fit determines the potential outcome, regardless of the components and efforts of the medical team!
