Introduction: In trans-tibial prosthetics, shape-capture methods are employed to create a representation of the residuum. Shape-capture methods can be grouped into the categories of ‘hands-on’, ‘hands-off’ and computer-aided design. Objective: This review examines the influences and trends of shape-capture methods on the outcomes of quality, comfort of user and clinical efficiency, in the population of trans-tibial prosthesis users.

Evaluating the Reliability of a Shape Capturing Process for Transradial Residual Limb Using a Non-Contact Scanner

Evaluated reliability of an optical scanner-based shape capture process for transradial residual limbs related to volumetric measurements and shape assessment in a clinical setting was found to be highly repeatable, with excellent intra- and inter-rater reliability that was comparable to the scanning of residual limb cast models.

Transtibial prosthetic socket fitting: Australian prosthetist perspectives on primary challenges, management strategies, and opportunities for workflow and technological innovation.

This study provides the first insights into prosthetist-identified challenges and limitations at different stages of the socket workflow and presents a starting point for more targeted research into innovation that may assist in these processes.

Silicone soft socket system for the treatment of geriatric transtibial amputees

Geriatric transtibial amputees fitted with prostheses attached via a silicone suction socket system showed significant improvements in walking distances and a high rate of satisfaction with the device.

A review of history of CAD/CAM system application in the production of transtibial prosthetic socket in developing countries (from 1980 to 2019)

Factors such as resources, accessibility, knowledge-gap and lack of experienced prosthetists remain the major causes of the lack of CAD/CAM system studies, yet the technology has not fully utilised in the developing countries.

It is demonstrated that, over the last 50 years, clinical research has improved the authors' understanding of socket designs and their effects; however, high-quality research is still needed.

Total Knee Arthroplasty in a Transtibial Amputee

It is found that after socket fitting, radiographic tibial varus alignment can correspond with a stump position that allows balanced loading of the knee and excellent function.

Investigation of Orthopedic Prosthesis Socket Management after Transfemoral Amputation by Expert Survey

The research goal was to clarify the socket treatment process with regards to the German context and showed that the orthopedic technicians focussing on the patient during the fitting process showed the importance of interaction and empathy.

Characterising Residual Limb Morphology and Prosthetic Socket Design based on Expert Clinician Practice

Functional, comfortable prosthetic limbs depend on personalised sockets, currently designed using an iterative, expert-led process, which can be expensive and inconvenient. Computer aided design and

3D-Printing and upper-limb prosthetic sockets; promises and pitfalls

It is shown that it is possible to utilise 3D scanning and printing, but only if the process is informed by expert knowledge, and strengths and drawbacks of a fully digitised, low-cost trans-radial diagnostic socket making process, informed by clinical expertise.

Technology for monitoring everyday prosthesis use: a systematic review

Activity monitoring technology used in conjunction with clinical scores and user feedback, offers significant insights into how prostheses are used and whether they meet the user’s requirements.



Systematic review of effects of current transtibial prosthetic socket designs-Part 1: Qualitative outcomes.

This review is an attempt to untangle the complexity of transtibial prosthetic socket fit, determine the most important characteristic for a successful fitting, and perhaps find some indication of

Systematic Review of Studies Examining Transtibial Prosthetic Socket Pressures with Changes in Device Alignment

Moderate evidence supports repeatable changes in pressure distribution for specific induced changes in component alignment, however, there also appears to be a significant individual component to alignment responses.

The effectiveness of total surface bearing compared to specific surface bearing prosthetic socket design on health outcomes of adults with a trans‐tibial amputation: a systematic review

The review finding, that the TSB design is as effective as the SSB socket design in improving health outcomes implies that prescription consideration may depend on prescriber knowledge, prosthetist skill‐set, funding availability and patient preference.

Clinical evaluation of trans-tibial prosthesis sockets: A comparison between CAD CAM and conventionally produced sockets

The quality of the CAD CAM sockets was at least at the same level as conventionally made ones, and the standard of conventional prosthetics in Sweden is considered to be high.

The use of a direct manufacturing prosthetic socket system in a rural community in South Africa: A pilot study and lessons for future research

The direct manufacturing prosthetic socket system could be considered as an alternative technique of socket manufacturing for individuals living in rural areas due to the shorter manufacture time and promising initial results, but further research on this topic with a bigger sample is recommended.

The CAD CAM system was assessed based on the number of socket attempts, number of prosthetic appointments, and temporary prosthesis rehabilitation time to evaluate the application of CAD CAM in the production of temporary trans-tibial prostheses.

Hands-Off and Hands-On Casting Consistency of Amputee below Knee Sockets Using Magnetic Resonance Imaging

Residual limb shape capturing (Casting) consistency has a great influence on the quality of socket fit. Magnetic Resonance Imaging was used to establish a reliable reference grid for intercast and

Measurement of the consistency of patellar-tendon-bearing cast rectification

The quality of fit of a trans-tibial patellar-tendon-bearing (PTB) socket may be influenced by consistency in casting, rectification or alignment, and the variations in the rectified casts between two experienced prosthetists are quantified.

Residual-limb shape change: three-dimensional CT scan measurement and depiction in vivo.

Registration of CT volumetric data sets to quantify residual-limb soft-tissue envelope change in lower-limB prosthetics is precise and can be used to detect the effect of prosthesis shape alterations.
