Lower Extremity Prosthetics

Transtibial (Below Knee) A transtibial prosthesis is an artificial limb that replaces a leg missing below the knee and commonly called prosthetic leg below the knee . Transtibial amputees are usually able to regain normal movement more readily than someone with a transfemoral amputation, due in large part to retaining the knee, which allows for easier movement.

In the prosthetic industry a trans-tibial prosthetic leg is often referred to as a “BK” or below the knee prosthesis.

Transfemoral (Above Knee) A transfemoral prosthesis is an artificial limb that replaces a leg missing above the knee. In general, a transfemoral amputee must use approximately 80% more energy to walk than a person with two whole legs. This is due to the complexities in movement associated with the knee. In newer and more improved designs, after employing hydraulics, carbon fiber, mechanical linkages, motors, computer microprocessors, and innovative combinations of these technologies give more control to the user.

In the prosthetic industry a trans-femoral best prosthetic leg is often referred to as an “AK” or above the knee prosthesis.

Vacuum Suction Socket Design Components.

Innovative Above-Knee and Below-Knee Design Sockets

The prosthetic socket is the device that joins your residual limb (stump) to the prosthesis. The socket is made just for you, according to the condition and shape of the residual limb.

Ischial containment socket

The socket has lower edges than typical transfemoral sockets and is as flexible as possible allowing muscles to move comfortably within the socket as they contract during activity and to improve comfort during sitting. The socket is held securely to the leg by suction from a vacuum pump, which makes for a firmer connection between the residual limb and prosthesis. Increased comfort, hip range of motion, and connectivity between the residual limb and prosthesis results in better functional performance for individual.

Ischial Containment Socket

Total Contact Socket

This means that, in the total-contact socket, the stump end is surrounded by a vacuum which keeps the prosthesis in position without a pelvic joint and belt. The total-contact socket is kept in place by its intimate fit around the stump. There is a moderate vacuum during swing phase.The intimate fit of the total-contact socket, which is made of plastic,has been designed with a view toward imitating the mechanism of the physiological pumping action performed by the muscles while walking.The pumping effect is accomplished by the amputee as he walks. In fact, a principal advantage of the total-contact socket is the mild, gentle counterpressure on the distal end of the stump during the stance phase. This positive pressure, alternating with the negative during the swing phase,improves circulation and reduces edema in the stump

Hi-Fidelity Socket

The High-Fidelity Interface was developed in response to patients’ complaints that their socket is not fitting snugly or comfortably, resulting in poor positional, operational, and functional control. It was designed with the understanding that a person can have the most technologically advanced prosthetic foot, knee, hand, or arm, but if doesn’t connect to the body properly, it won’t deliver the proper results and the individual is less likely to wear it and enjoy the benefits it is intended to deliver.

Revo Adjustable Above-Knee and Below Knee Socket Design

It starts with adjustable panels placed around the soft tissue areas of the limb. These panels are lined with padding and connected to a RevoFit™ dial that is easily turned to increase or decrease compression around the limb. Changes in activities, weight fluctuations, limb volume changes—all of these can be accommodated for with an adjustable socket.Adjustable Sockets solve these problems by giving amputees the ability to adjust the fit of their socket with a simple twist of a dial.

Microprocessors controlled knees provide a more sophisticated method of control to a prosthetic knee. These more complex knee joints are designed to help you walk with a much more stable and efficient gait that more closely resembles a natural walking pattern.

Microprocessor Controlled Foot/Ankle.   These foot/ankle components have small computer-controlled sensors that process information from both the individual's limb and the surrounding environment to adjust to various needs. ... Powered feet provide propulsion during ambulation to enhance walking capabilities in real-time.

Carbon Fiber Dynamic Response Feet.  Dynamic response feet are usually made from stiff carbon fibre elements which act like springs: deforming under load and returning to their original shape when unloaded.... While the feet do not store energy, they do return some of the energy developed during walking. This lowers overall energy expenditure.

Adjustable Heel Height

An adjustable heel height foot allows the wearer to use different shoes easily. With the push of a button, the foot can be adjusted to accommodate the different shoes.

Custom Liners

Every person is unique and all residual limbs are not the same. Custom liners are used for less than optimally shaped residual limbs. They are suitable for patients with a sensitive, bony or scarred residual limb and low to high activity level. They provide greater durability and help ensure a correct fit and optimal functionality.

Partial Foot Silicone Prosthesis

A partial foot prosthesis can help distribute the weight-bearing forces comfortably on the remaining foot and allow for the patient to walk for a longer period of time without as much pain or discomfort. They are custom fabricated from a special blend of Silicone which offers flexibility, comfort, durability and stain resistance. They rarely cause dermatological reactions and detailing such as hair, freckles, age spots, etc. can be added.

Specialty Products

Designed for specific activities that an Amputee would like to pursue but with their normal prothesis those activities would be limited or impossible.

Cosmesis

Cosmetic prosthesis has long been used to disguise injuries and disfigurements. With advances in modern technology, cosmesis, the creation of lifelike limbs made from silicone or PVC has been made possible. Such prosthetics, such as artificial hands, can now be made to mimic the appearance of real hands, complete with freckles, veins, hair, fingerprints and even tattoos. Custom-made cosmeses are generally more expensive while standard cosmeses come ready-made in various sizes, although they are often not as realistic as their custom-made counterparts. Another option is the custom-made silicone cover, which can be made to match a person’s skin tone but not details such as freckles or wrinkles. Cosmeses are attached to the body in any number of ways, using an adhesive, suction, form-fitting, stretchable skin, or a skin sleeve.
