Abstract

Socket is an important part of every prosthetic limb as an interface between the residual limb and prosthetic components. Biomechanics of socket-residual limb interface, especially the pressure and force distribution, have effect on patient satisfaction and function. This paper aimed to review and evaluate studies conducted in the last decades on the design of socket, in-socket interface pressure measurement, and socket biomechanics. Literature was searched to find related keywords with transtibial amputation, socket-residual limb interface, socket measurement, socket design, modeling, computational modeling, and suspension system. In accordance with the selection criteria, 19 articles were selected for further analysis. It was revealed that pressure and stress have been studied in the last decaeds, but quantitative evaluations remain inapplicable in clinical settings. This study also illustrates prevailing systems, which may facilitate improvements in socket design for improved quality of life for individuals ambulating with transtibial prosthesis. It is hoped that the review will better facilitate the understanding and determine the clinical relevance of quantitative evaluations.

Highlights

Amputation constantly remains a cause of concern for individuals, their families, and society
Several articles were excluded as being conducted on dental prosthetics, upper limb prosthetics, and implants, or were common between the databases
Various prosthetic components have been investigated in the past

Summary

Introduction

Amputation constantly remains a cause of concern for individuals, their families, and society. Incidence of lower limb amputation has increased over the years [1,2,3]. Amputations, of the lower limb, are increasing in developed countries [4]. Motorcycle accidents [3] and diabetes, are two major causes [5]. Prosthetic satisfaction is a subjective notion [6]. Prosthetists consider biomechanical parameters, but people with lower limb amputation remain dissatisfied with prostheses [7, 8]. Comfort primarily involves the pressures between the socket and residual limb. The socket fit, type of prosthetic suspension, and alignment of the prosthesis can alter pressures on the residual limb [11,12,13,14]
