January | February 2019 40 Technology An interesting feature that becomes apparent for Infinite Socket users is how the thermoplastic carbon frame of both the TT-S and TF Infinite Socket drowns out harsh forces when walking. The structural frames are designed to flex and diminish these jarring forces exerted by the ground. This “dynamic flex” or bending permits the socket shape to change along with the user in an anatomical fashion, dampening ground forces felt through the Infinite Socket. Benefits of the Infinite Socket include: • Adaptability. The multi-durometer socket provides select areas of flex and rigidity, relieving areas of bony prominences and reducing chances of skin ulcerations. • Self-adjustability. Allows prosthetic users to gain full control of their socket fit. A user can self-adjust their socket anytime through their clothing. • Full range of motion. Above‑knee and below-knee socket designs permit unrestricted range of motion. • Modular setup. The TT-S for below-knee amputees features a modular back pad to improve knee flexion comfort and range. A height-adjustable ischial seat and inner brim on the Infinite Socket ™ TF improves sitting and weight‑bearing comfort for above‑knee amputees. Socket-less Socket ™ by Martin Bionics Martin Bionics offers a prosthetic socket with an innovative design that removes many of the pain points of the traditional socket. The Socket‑less Socket ™ eliminates the hard static brim of traditional sockets and instead uses soft, conforming materials and an open frame design, allowing your residual limb to flex and breathe. The need for prosthetic socks to help manage volume changes has been replaced with self‑adjustable ratchets, allowing you to fine‑tune your socket fit. The inherent conformability of Martin Bionics’ technology provides a comfortable fit all day. Some key features of the Socket-less Socket ™ are: • Fits all limb types and sizes. Their technology can be fit on all limb types, from pediatric to obese (even over 400 pounds), any length residual limb, geriatric to athletic, and all amputation levels. • Sitting comfort. Their SwingBrim ™ technology conforms to the above-knee prosthetic user just like a hammock, providing a soft, floating, cushioned seat on every step. Sitting comfort is improved by eliminating the lump you feel along the brim in traditional above-knee sockets. • Full range of motion. The Socket‑less Socket’s ™ conforming materials allow you to bend and sit comfortably with unrestricted range of motion. • Micro-adjustable. Incrementally adjust your Socket-less Socket ™ over your clothing to maximize comfort throughout the day. Some final thoughts For the most part, traditional prosthetic sockets are fixed and rigid in shape; aside from managing sock ply, they’re limited in how much self-adjusting is available to the wearer. In contrast, all three technologies discussed here offer socket innovations that are very adjustable and forgiving. Depending on your amputation level, lifestyle, and your overall medical condition, each of these three technologies is different. However, they all share a common theme: They are focused on providing maximum comfort, empowerment, adjustability and innovation. The differences lie in user preference and input from your prosthetist. Martin Bionics Socket-less Socket
