Prosthetic Rotation Adapter
The ROT Rotation Adapter is an advanced functional prosthetic component specifically engineered to enhance comfort and mobility in above-knee prosthetic fittings. By enabling controlled 360° rotational movement of the prosthetic limb when the knee is flexed, this modular adapter allows users to perform daily activities—such as driving, putting on shoes, and sitting—more naturally and with greater ease. Its compact and durable design integrates seamlessly into modular prosthetic systems, providing a reliable and practical solution for enhanced user independence.
Prosthetic Rotation Adapter M36
The ROT M36 Rotation Adapter is an advanced functional prosthetic component specifically engineered to enhance comfort and mobility in above-knee prosthetic fittings. By enabling controlled 360° rotational movement of the prosthetic limb when the knee is flexed, this modular adapter allows users to perform daily activities—such as driving, putting on shoes, and sitting—more naturally and with greater ease. Its compact and durable design integrates seamlessly into modular prosthetic systems, providing a reliable and practical solution for enhanced user independence.
