Advanced Lower Extremity Prosthetics
The loss of a lower limb has a profound impact on a person’s ability to move through life.
Today, advanced materials and designs are restoring mobility to people of all ages and from every background. Whether challenged by illness, injury or accident, Innovative Clinic patients are empowered.
ABOVE-KNEE PROSTHETICS
An above-knee (AK) prosthesis consists of a custom-made socket combined with a supportive frame, knee unit, pylon, and foot. Sometimes a suspension sleeve or harness may also be necessary.
BELOW-KNEE PROSTHETICS
A below-knee (BK) prosthesis will typically consist of a
custom-made socket, a pylon and a foot. Sometimes a suspension sleeve or harness may also be necessary.
ANKLE DISARTICULATION
Syme’s amputation is an ankle disarticulation (the removal of the foot through the joint) with removal of the malleoli (the two rounded protrusions on either side of the ankle) then forward rotation of the heel pad over the end of the residual tibia
FOOT OPTIONS
The short space between the end of the residual limb and the floor means that a standard prosthetic foot usually has to be modified in order to fit correctly. Possible foot choices include the Solid Ankle Cushion Heel (SACH) foot or a carbon reinforced energy-storing foot.
PARTIAL FOOT
Partial amputations of the foot include: toe amputation; mid foot amputation (metatarosphalangeal, transmetatarsal); Lisfranc amputation; and Chopart amputation.
Options:
Prosthetic options include: no prosthesis; rigid footplate with arch support combined with a rocker bottom shoe sole; custom-molded foot orthosis/ prosthesis; custom-molded shoes; modified ankle-foot orthosis with a toe filler; foot prosthesis (a custom-molded socket attached to a semi-rigid foot plate with a toe filler).
Surgical revision is sometimes necessary in order for the person to successfully wear a prosthesis.
HOW TO CALCULATE WHICH PROSTHETIC COMPONANTRY IS SUITED FOR YOU?
When you search for prosthetic componentry online you will be surrounded by a vast ocean of products, each claiming to be better than the next. The prescription protocol when it comes to prosthetic componentry is totally based on the activity level of the user, the future aspirations of the user and the necessary funding available.
At MPPO we dedicate extensive time to explain the different options available that will be suited for each users’ individual needs. We how ever encourage our clients to do extensive research on what is available and be part of the prescription protocol. We are in the fortunate position to offer no obligation trials on all componentry, creating an environment where the decision is in the hands of the user and the guidance of the Orthotist.
Below you will find some componentry the use with great success at our clinic.
GENIUM BIONIC PROSTHETIC SYSTEM
The Genium Bionic Prosthetic System is the world’s only microprocessor controlled knee that can anticipate your movements and adapt instantaneously in order to function as close to a natural leg as possible. The Genium allows you to focus on what you are doing, not your prosthesis.
Realizing your potential naturally:
Culminating decades of research and development, the Genium Prosthetic Knee combines an accelerometer and gyroscope with today’s most advanced sensing and control technologies.
Utilized for the first time with a prosthesis, Genium’s gyroscope collects data in three dimensions to identify where it is in space while the accelerometer tracks its speed. These same technologies enable Wii gaming systems to sense and react to user movements and devices such as the iPad to turn and adjust on-screen images as they’re repositioned.
Genium’s array of four sensors deliver an unprecedented quantity and quality of data to three microprocessors – the most ever utilized by a prosthetic knee – that allows them to predict what will happen next. By applying sophisticated rule sets, these microprocessors intuitively move the prosthesis in multiple directions in much the same the way a normal leg would respond. As a result, users can side-step, walk backwards, shuffle step, stop short, pivot on their prosthetic leg and perform a wide range of common movements naturally without concentrating.
Genium also adapts immediately to changes in direction, speed or pace. Its fluid motion allows the knee to get in front of the body rapidly and support it even in a bent position. And unlike other prosthetic legs, it lets amputees step over obstacles instead of walking around them.
C-LEG MICROPROCESSOR KNEE:
With C-Leg® microprocessor-controlled knee you can speed up, slow down, take on hills and go down stairs step-over-step—all with a secure, more natural gait.
How the technology works:
The revolutionary microprocessor that controls the C-Leg Microprocessor Knee receives feedback from multiple sensors 50 times a second, allowing the knee to anticipate your next move and make adjustments in real time. This keeps your knee stable when you weight it, free-swinging when you step through—and always ready to support you if you stumble.
Stumble Recovery
Whenever the C-Leg Microprocessor Knee senses that you’re in an insecure position—such as when you trip or stumble—it will stiffen to provide the support you need to recover. When it senses that you’re secure again, it offers its normal, reliable support.
Multiple Modes for Multiple Uses
The C-Leg Microprocessor Knee offers several functional modes. The first two modes can be set for walking and other favourite activities, such as driving or riding a bike. A new “standing” mode lets you lock the leg yourself between 7 and 70 degrees, helping you use less energy no matter what you stand for.
Switching between modes is as easy as bouncing on your toe—or a press of the wireless remote control.
C-Leg Microprocessor Knee Protector
The C-Leg Microprocessor Knee Protector is a tough exterior shell that keeps your C-Leg Microprocessor Knee protected from the environment. It’s easy to put on and take off and includes an anti-slip feature to make the knee more stable when you kneel.
The C-Leg Microprocessor Knee Has You Covered
A three-year warranty is standard with the C-Leg Microprocessor Knee and includes a free service check at 24 months. We even provide a loaner microprocessor knee during the service period.
How to Be Fit With the C-Leg Microprocessor Knee
The C-Leg Microprocessor Knee must be fit by a C-Leg Microprocessor Knee qualified prosthetist. They’ve invested two full days in the classroom to master the customizing software, and will set the knee for all the ways you walk—fast and slow, indoors and out.
