Address the Critical Need for Advanced Prosthetic Sockets in Conflict Zones
When discussing prosthetic limbs, the focus often lands on the visible, mechanical components like the knee joint or the foot. However, the most critical element for user comfort and mobility is the prosthetic socket—the interface that connects the residual limb to the artificial device. For individuals who have experienced traumatic amputations, the residual limb is rarely uniform in shape. Traditional, static sockets fail to accommodate the natural fluctuations in limb volume that occur throughout the day due to changes in temperature, humidity, and physical activity.
Understanding the Biomechanics of Limb Volume Changes
Biomechanics research demonstrates that a residual limb can change in volume significantly over a 24-hour period. In a high-stress environment, or even during routine daily activities, fluid shifts and muscle contraction cause the limb to swell or shrink. A rigid socket that fits perfectly in the morning may become excruciatingly painful by the afternoon, leading to blisters, skin breakdown, and a complete inability to wear the prosthesis. For injured military personnel attempting to reintegrate into civilian life or return to active duty, these biomechanical incompatibilities represent a major barrier to independence.
The Impact on Daily Mobility and Independence
Poor socket fit directly correlates with reduced mobility. When a prosthetic causes pain, the user naturally alters their gait to compensate, which leads to secondary issues such as lower back pain, joint degradation in the intact limb, and overall physical exhaustion. By prioritizing innovative prosthetic design that adapts to the limb rather than forcing the limb to adapt to the socket, researchers can drastically improve the user’s ability to walk, work, and manage daily tasks. This focus on adaptability is what sets the current Lancaster University research apart from conventional prosthetic care.
Combine Biomechanics Research and Additive Manufacturing
To solve the issue of static socket fitting, the research team led by Professor Allan Rennie from the School of Engineering at Lancaster University is leveraging additive manufacturing, commonly known as 3D printing. This technology allows engineers to move away from traditional, labor-intensive plaster casting methods toward a highly precise, digital workflow.
Utilizing 3D Scanning for Customization
The process begins with advanced 3D scanning of the residual limb. Unlike plaster casts, which capture only a static snapshot, digital scans can be taken quickly and repeatedly to map the exact topography of the limb. This data is then used to generate a digital model of the socket. Because the design exists in a digital environment, engineers can easily manipulate the geometry to create targeted relief areas, adjust wall thickness for varying flexibility, and integrate structural lattice patterns that allow the socket to flex and breathe.
Balancing Cost-Effectiveness with High-Quality Outcomes
A major challenge in providing UK prosthetic limbs and exporting these technologies to Ukraine is cost. Traditional custom sockets are expensive and time-consuming to fabricate. Additive manufacturing addresses this by reducing material waste and eliminating the need for expensive tooling. Professor Rennie emphasizes the necessity of balancing cost-effectiveness with optimal patient outcomes, particularly given the massive scale of demand in Ukraine, which includes both military personnel and civilians, notably children. By utilizing additive manufacturing, the team can produce customized, reconfigurable sockets at a fraction of the traditional cost, ensuring that more patients receive the personalized care they require.

Leverage Motion Capture Technology for Data-Driven Design
Designing a better socket requires more than just a 3D map of the limb; it requires an understanding of how the limb moves within the socket under dynamic conditions. Dr. Hannah Jarvis, a Lecturer in Biomechanics at Lancaster Medical School, is spearheading this aspect of the project by utilizing advanced motion capture systems.
Implementing Qualisys Systems in Ukraine
Through a generous equipment donation from Qualisys Motion Capture and Technology Systems, Dnipro University of Technology in Ukraine has received state-of-the-art 3D cameras and software. This technology is essential for gathering quantitative data on how amputees walk, stand, and move. Ukrainian researchers are currently training at Lancaster University to master this scientific analysis, ensuring that the capacity to conduct high-level biomechanics research remains within Ukraine long after the initial collaborative project concludes.
Analyzing Pressure Points and Gait Mechanics
Motion capture allows researchers to track the kinematics (movement patterns) and kinetics (forces) of a patient’s gait. By combining this movement data with pressure mapping inside the socket, the team can identify exact points of friction, excessive pressure, or harmful slippage. This objective data removes the guesswork from socket fitting. Instead of relying solely on a patient’s verbal feedback, which can be subjective, engineers can use precise biomechanical data to iteratively refine the innovative prosthetic design, ensuring the final product minimizes tissue strain and maximizes mechanical efficiency.
Strengthen International Partnerships Through the Twin for Hope Initiative
This research does not occur in a vacuum. It is the direct result of a strategic international partnership facilitated by the Twin for Hope initiative, launched in 2022 by Universities UK International and the Cormack Consultancy Group. This program pairs UK institutions with Ukrainian universities to support academic resilience and capacity building during the war.
Collaborating with Dnipro University of Technology and Kharkiv National Medical University
Lancaster University is partnered with Dnipro University of Technology, with Dr. Serhii Onyshchenko serving as the co-lead for the project. The collaboration also actively involves Kharkiv National Medical University, bringing essential medical and clinical perspectives to the engineering process. Dr. Oleksandr Kryvoshapka, Vice-Rector for Research and Education at Kharkiv National Medical University, highlights that this collaboration goes beyond mere research; it is a symbol of support and trust that is actively shaping a new standard for medical education and rehabilitation in Ukraine. This multidisciplinary synergy ensures that the prosthetics developed are not just engineering marvels, but clinically viable medical devices.
Integrating Lived Experience from UK Amputees
A unique and vital component of this partnership is the inclusion of lived experience. Gregg Stevenson MBE, an Armed Forces Covenant Project Manager at Lancashire County Council, lost his lower legs in 2009 while serving in Afghanistan. Stevenson is actively supporting the Lancaster University team by participating in scanning and motion technology training. His firsthand insight into the daily realities of wearing prosthetics provides an invaluable reality check for the researchers. Stevenson notes that maintaining mobility is crucial for returning to work and family life, and he views this innovative work as a means to fundamentally improve the everyday lives of people with prosthetic limbs globally.

Plan for the Future of UK Prosthetic Limbs and Global Rehabilitation
The immediate goal of the Lancaster University, Dnipro University of Technology, and Kharkiv National Medical University coalition is to produce a functional, adaptive prosthetic socket prototype for testing by February 2027. This timeline reflects the complexity of engineering a device that must be highly durable, easily reproducible, and capable of dynamic adaptation.
From Prototype to Patient by 2027
Creating the prototype is only the first phase. Once the adaptive socket is validated through biomechanical testing at Lancaster, the digital designs and manufacturing protocols will be transferred to Dnipro University of Technology. The additive manufacturing approach ensures that once the prototype is finalized, production can be rapidly scaled locally in Ukraine. This localized production capability is critical for long-term sustainability, as it allows for continuous fittings, adjustments, and re-fittings as a patient’s body changes over the years following an amputation.
Setting New Standards in Medical Education
Beyond the immediate physical benefits for amputees, this project is establishing a new paradigm for how prosthetic care is taught and researched. By integrating 3D scanning, motion capture, and additive manufacturing into the training of Ukrainian students and researchers, the Twin for Hope initiative is building a robust foundation for the future of Ukraine healthcare. The knowledge exchange ensures that the next generation of biomechanical engineers and medical professionals in Ukraine will be equipped with the skills necessary to continue advancing innovative prosthetic design independently.
The work being done at Lancaster University serves as a prime example of how academic research can be directly translated into profound humanitarian impact. By focusing on the specific, measurable challenges of socket fitment and combining it with international cooperation, this project is poised to change the standard of care for traumatic amputees in Ukraine and establish new best practices for UK prosthetic limbs.
