Martin Bionics has developed new technology on socket design for hip disarticulation prostheses. It is called the Bikini Sockets because of its low profile and lightweight design. This new socket allows patients to use iliac crest stabilizers instead of the typical bucket design used in current hip disarticulation prostheses. While this design may not be ideal for all patients, POSI believes our practioners should always be knowledgeable in new prosthetic designs and technology.

The Socket-less Socket truly conforms to the user, providing a custom-fit socket every time you put it on. If you’re the kind of person who wants full control of how your socket fits, this technology is for you. Fitting a prosthetic socket is now micro-adjustable in real-time to create a socket as individual as the toughest patient.Our patent pending swing technology perfectly conforms to the user just like a hammock, providing a soft floating cushioned seat on every step.

Conventional prosthetics are static in shape, and require frequent fitting adjustments to match the ever-changing human body. Our technology fits differently. We enable you to micro-adjust for a comfortable fit every time you put your prosthesis on.

Our NASA-based lightweight design and materials are only a fraction of what conventional sockets weight – with a typical weight reduction of nearly 2 pounds. You’ll be amazed at how light a socket can feel.

Introducing a revolutionary new way of fitting a flexible inner socket. Our flower distal cup technology with our special NASA-based mesh fabric creates a form-fitting inner socket that’s flexible enough to fold up in the palm of your hand.
