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

Abstract

Abstract-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 whether a particular prosthetic socket type might be best for a given situation. Further, it is intended to provide directions for future research. We followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and used medical subject headings and standard key words to search for articles in relevant databases. No restrictions were made on study design or type of outcome measure. From the obtained search results (n = 1,863), 35 articles were included. The relevant data were entered into a predefined data form that incorporated the Downs and Black risk of bias assessment checklist. Results for the qualitative outcomes (n = 19 articles) are synthesized. Total surface bearing sockets lead to greater activity levels and satisfaction in active persons with amputation, those with a traumatic cause of amputation, and younger persons with amputation than patellar tendon bearing sockets. Evidence on vacuum-assisted suction and hydrostatic sockets is inadequate, and further studies are much needed. To improve the scientific basis for prescription, comparison of and correlation between mechanical properties of interface material, socket designs, user characteristics, and outcome measures should be conducted and reported in future studies.

Effect of temperature-control liner materials on long-term outcomes of lower limb prosthesis use: a randomized controlled trial protocol

“…Previously published liner comparison studies investigated outcomes after wearing times of two weeks [17], three weeks [18], four weeks [19], and 2.5 months [20] and have been criticized for short accommodation times and the resulting lack of firm conclusions [21].…”

The Söderberg Socket 2.0: A Technical Note

“…Numerous transtibial prosthesis technologies work to facilitate an improved dynamic fitting or aid the overall function of the individual. 1 Various modifications to the socket can augment suspension characteristics and even assist gait of the user. 2 Some companies have focused on utilizing ratcheting technologies to aid in adjustability of the prosthesis socket, such as the BOA system (Click Medical, BOA, Steamboat Springs, Colorado, USA).…”

“…This conventional design has still remained, even if supracondylar and cuff suspension methods have shifted towards vacuum. 1 Recent transtibial socket clinical guidelines have served to aid the prosthetist decision ABSTRACT BACKGROUND: Transtibial prosthesis socket trim lines have remained fairly consistent over the past decade, and based on methods such as a supracondylar cuff suspension. However, with vacuum suspension methods, trim lines can change.…”

Development of an Easy and Effective Attachment System for Lower Limb Prosthesis

“…Even with a well-performed amputation and a well-fitted prosthesis, some patients have persistent symptoms of residual extremity pain, tissue breakdown and a sense of instability [4]. Many of these problems are associated with poor prosthesis fitting and suspension system since they are strongly related to the functional efficiency and comfort level of the prosthesis [5].…”
