HiFi Interface Technology – Prosthetic Socket

Gone are the days of amputees simply tolerating their prosthesis, our team is ready to give you a socket that empowers you!

What is HiFi?

High-Fidelity (HiFi) Interfacehifi imager by biodesigns, inc is the newest technology redefining how a prosthetic socket should fit, providing the ultimate in comfort and function. The HiFi Interface, with patented and patents-pending Osseostabilization™ and Osseosynchronization™ technology, delves deeper to capture and control the underlying bone. This allows the socket to connect skeletally with the patient’s residual limb, think of osseointegration without the surgery and with a removable prosthesis. Motion and force are captured closer to the bone, creating a more precise reaction from the prosthesis and more instinctive reaction from the user. The result is dramatically enhanced performance, greater energy efficiency, security, safety, increased endurance, greater comfort and a higher level of confidence for wearers of all activity levels.

There is a better way, and it doesn’t involve surgery.

A Higher Standard

The HiFi Interface and technology addresses common issues with ill-fitting prosthetic sockets, including; falls, instability, pain, blisters, pistoning, rotation, uneven gait, and uncomfortably high trim lines. Some prosthetic wearers complain of a loss of sensory information resulting in poor proprioception and a reduction in walking confidence and speed; all associated with high mental and physical fatigue. A lack of physiological feedback to the brain contributes to phantom limb pain, a major problem for amputees. HiFi wearers report their prostheses feel more like a part of them, feel connected to them, with many reporting phantom sensations returning to their limbs, allowing them to feel the ground. Many patients report a reduction in mental fatigue because they forget they are wearing their prosthesis. Are you ready to experience HiFi?

This socket is made for ultimate comfort & fit for the patient.

Who is a candidate for the HiFi Interface?

We have had great success fitting both upper and lower limb wearers. And while this design benefits individuals of all activity levels, it is extremely effective for those who are very active and demanding on their prosthesis, especially above-knee and upper limb amputees who are looking for greater stability and comfort.

Don’t just take our word for it!

HiFi patient, Angelia, sought out biodesigns for a HiFi Interface socket after receiving a
socket from a well knowncompany who close up of hifi prosthetic leg socketprosthetic leg sockets comparisonpromised simple sockets with clean trim lines that allow users the ultimate comfort. Angelia’s socket was anything but the promises she was sold. Her socket had high trim lines and caused her instability and pain, especially on her femoral artery where one of the straps was located and impinging her femoral artery. You can see in the below images that her old socket was very large and bulky, prohibiting her from wearing certain clothing, like jeans.
As an active duty member of the military, Angelia needed a socket she could wear all day under intense and demanding physical requirements. She found that with HiFi. With her new socket, Angelia’s gait is now faster, more symmetrical, has a narrower base, and allows her the ability to fully live her life and reach her goals. Angelia shared her HiFi experience in her own words.

“With the subischial HiFi Interface, my gait feels more fluid and I have more of a gliding motion as I walk as opposed to sinking every time I step. I am still getting used to the HiFi design, but it allows me to be much more aware of my muscles and core and how to use them properly again. It seems that the more work I put in, the better it feels. By the end of the day my gait feels flawless. I’m actually really excited to wear my jeans again. Overall, as compared with the other sockets, it’s a world of difference.”
