Prostheses that are changing the lives of our patients

Synergy Prosthetics is the premier “MOBILE” Prosthetics provider in California servicing amputees where they reside minimizing downtime without their prosthetic device. Here are a few of the prostheses that are changing the lives of our patients:

Above the knee amputees require a knee joint and lower leg to ambulate. The knee joint and lower leg components attach to a socket. Custom sockets are created for each individual amputee and fit onto their residual limb using a number of systems and methods to stay in place.

The term “ischial containment” is rather self-descriptive. It describes several similar concepts in socket design in which the ischium (and in some cases the ischial ramus) are enclosed inside the socket.

Objectives that would ideally be achieved in the ischial containment socket:

Maintenance of normal femoral adduction and narrow-based gait during ambulation.
Enclosure of the ischial tuberosity and ramus, to varying extents, in the socket medially and posteriorly so that forces involved in maintenance of mediolateral stability are borne by the bones of the pelvis medially and not just by the soft tissues distal to the pelvis, that is to say, creation of a “bony lock.”
Maximal effort to distribute forces along the shaft of the femur.
A decreased emphasis on a narrow AP diameter between the adductor longus-Scarpa’s triangle and ischium for the maintenance of ischial-gluteal weight bearing.
Total contact.
Utilization of suction socket suspension whenever possible.

This suspension system uses a strap attached to the bottom of a liner which is fed through an opening at the bottom of the socket and then attaches to the outside of the socket. The ease of use with this system may be a good choice for new amputees or amputees that are less active and are just getting used to their new device. This is a simple and reliable system and makes art easy for an amputee to don and doff their device.

Below the knee and above the knee amputees can both benefit from this style of suspension. A constant monitored suction is controlled by an electric/mechanical pump attached to the socket.

This pump pulls the liner and the amputees residual limb inward towards the socket walls. A great benefit of this system is the limited movement within the socket, there is very limited excessive motion, therefor less friction. This design also improves circulation, greatly improving the overall health of the residual limb.

With trans-tibial amputees, this system uses body weight to expel excess air through a one way valve creating an airtight seal between the knee sleeve at the top of the socket.

With trans-femoral amputees a sealing liner ring creates the seal at the top of the socket.

This system affords a high level of comfort due to the vacuum created between the suspension sleeve and the liner/skin. When the amputee ambulates the air inside the socket is forced out forming an airtight strong connection to the residual limb.
