XtremityTT® Preform Socket
Each preform is injection molded with a distal base that is connected to the modular suspension system and alignment base. We offer 7 sizes in standard and conical profiles.
XtremityTT® Suspension Systems
Modular and interchangeable suspension systems for pin-lock, suction, or vacuum suspension.
XtremityTT® FLEX
A flexible inner socket that provides uniform wall thickness, is easy to fabricate with minimal lab space and equipment, and reduces material waste.
XtremityTT® Benchtop Heating Unit
Specially engineered heating unit for uniform heating of the preform with a minimal footprint in your lab space.
To support the patient’s continuous, comfortable, and long-term use of their prosthesis, the prosthetist can use a heat gun to make spot adjustments at any time throughout the life of the prosthesis.
Environmental / Health Benefits
Fabrication and assembly of the XtremityTT® socket is accomplished in about one hour, in a small workspace, without a large oven or vented room for grinding and finishing the socket.
No layup. No lamination. No hazardous raw materials or irritating carbon dust. XtremityTT® is a healthier choice for clinic employees and more sustainable for our environment.
Quality Manufacturing in the USA
The XtremityTT® is the first socket created by injecting a proprietary carbon reinforced polymer (a material no prosthetist has ever experienced) into machined tools to create a precise “Preform” available in four sizes and two profiles (Standard or Conical). The Preform can be heated in a compact Benchtop Heating Unit and custom vacuum-formed to a model of the residual limb.
All components are injection molded, CNC milled from aircraft grade aluminum and stainless steel, or 3D printed in Colorado (100% made in the USA) by ISO suppliers.
The Most Tested Socket Ever
While there are no existing standards or requirements for socket testing, Xtremity’s product development and engineering team completed the most testing ever on transtibial socket technology. Xtremity invested millions of dollars creating precise methods and devices to conduct a vast range of tests to validate the structural durability, performance, safety and benefits of the XtremityTT® Socket System.
The XtremityTT® Socket System was load tested (3 million cycles, heel and toe) adhering to ISO standards for prosthetic devices. A 38-patient controlled study involving six clinics, as well as a battery of tests for ultimate strength, torsion, pressure mapping and material creep, were completed prior to the product’s release. Patient “testers” included extreme athletes who logged more than 30 million steps.
XtremityTT® Socket System IRB Study Abstract
Xtremity performed an IRB approved study of 6 sites in the US and Canada. 38 subjects agreed to participate in this single arm, prospective, multi-center study. The subjects were between 19-90 and had a unilateral or bilateral TT amputation. 75% had their current well-fitting socket duplicated to reduce variables and utilized their existing componentry. A PEQ was administered to each subject prior to fitting with a new socket and after 21 days of use with an Xtremity Socket. Other surveys were also administered.
Results tabulated by an outside agency demonstrated significant improvements in comfort, walking satisfaction, material feel, and energy needed to ambulate. Average time to receive prosthesis was 2.81 days and the majority felt the weight of the prosthesis was improved over their existing device. 81% of subjects wanted to keep their Xtremity socket over their existing device. All practitioners felt the Xtremity socket would save them time (81%) and 100% felt it would save their clinician time.
