Quantification of rectifications for the Northwestern University Flexible Sub-Ischial Vacuum Socket

The human–prosthesis interface is one of the most complicated challenges facing the field of prosthetics, despite substantive investments in research and development by researchers and clinicians around the world. The journal of the International Society for Prosthetics and Orthotics, Prosthetics and Orthotics International, has contributed substantively to the growing body of knowledge on this topic. In celebrating the 50th anniversary of the International Society for Prosthetics and Orthotics, this narrative review aims to explore how human–prosthesis interfaces have changed over the last five decades; how research has contributed to an understanding of interface mechanics; how clinical practice has been informed as a result; and what might be potential future directions. Studies reporting on comparison, design, manufacturing and evaluation of lower limb prosthetic sockets, and osseointegration were considered. This review demonstrates that, over the last 50 years, clinical research has improved our understanding of socket designs and their effects; however, high-quality research is still needed. In particular, there have been advances in the development of volume and thermal control mechanisms with a few designs having the potential for clinical application. Similarly, advances in sensing technology, soft tissue quantification techniques, computing technology, and additive manufacturing are moving towards enabling automated, data-driven manufacturing of sockets. In people who are unable to use a prosthetic socket, osseointegration provides a functional solution not available 50 years ago. Furthermore, osseointegration has the potential to facilitate neuromuscular integration. Despite these advances, further improvement in mechanical features of implants, and infection control and prevention are needed.

“…A further five were partly related to this topic by, for example, describing a model or scale to facilitate professional communication; however, these studies did not include any relevant outcome data. [7][8][9][10][11] Of the five remaining studies, two did not include outcomes: one compared P&O programmes (including courses on communication skills) 12 and the other discussed the development of a visualization aid, but not if using this aid improved communication or clinical outcomes. 13 The only three studies in which data on this topic were presented included an observational study and two semi-quantitative studies.…”

A toolkit for prosthetists and orthotists to facilitate progress in professional communication over the next 50 years

Background: In this celebratory issue of Prosthetics and Orthotics International, we review professional communication skills in the field of prosthetics and orthotics. Objective: We aim to reflect on communication skills in the past 50 years, to discuss developments in the coming 50 years, and to create a toolkit and research agenda to facilitate progress in professional communication in the next 50 years. Results: Despite being a key area in prosthetics and orthotics training programmes, we found no studies on professional communication with an experimental design published in Prosthetics and Orthotics International. As an alternative, we provide clinical reflections on the changes in professional communication in the past 50 years, and we discuss questionnaire-based and qualitative studies that provide evidence for the importance of communication in pedorthic footwear provision. In the coming 50 years, professional communication in the field of prosthetics and orthotics may be impacted by aging populations, global mobility, information technology, technological advances and emphasis on prevention. We discuss each of these topics. To facilitate progress in professional communication, we have created a toolkit with resources for prosthetics and orthotics professionals, prosthetics and orthotics students and other interested professionals. Conclusions: We hope this toolkit will inspire others to use, extend and implement it in their daily practice. As a research agenda, we strongly recommend undertaking research on interventions to improve professional communication and to study its effect on clinically meaningful outcomes.

“…For both sockets, positive model rectification requires only plaster removal. 1,5 While the same clinical algorithm 1 is used for both sockets, the rectification maps in Figure 2 (produced using the procedure described in Fatone et al 5 ) compare rectifications for the NU-FlexSIS and NU-FlexSIV sockets for the same residual limb. While rectifications are similar, the boomerang outline highlights that the posterior rectification terminates proximal to the seal and that the proximal-lateral rectification is slightly deeper for the NU-FlexSIS socket.…”

Between January 2015 and March 2018, 266 Northwestern University Flexible Sub-Ischial Suction sockets were fit successfully using the described technique modifications. Clinical relevance A passive suction version of the Northwestern University Flexible Sub-Ischial Vacuum socket-the Northwestern University Flexible Sub-Ischial Suction socket-broadens the application of sub-ischial sockets to a larger proportion of the population with transfemoral amputation.
