The insulated environment of the lower-limb prosthesis can result in elevated residual-limb skin temperatures that may contribute to skin irritation, blistering, and a reduced quality of life. The design and materials of the prosthetic socket, suspension system, and liner can potentially alleviate these conditions, but the thermal load may vary with activity and location within the socket. To c...

To study and compare frontal plane kinetics and kinematics at knee joint during the gait cycle in persons with transtibial amputation using Patellar tendon bearing (PTB) suprapatellar (SP) cuff suspension and PTB supracondylar (SC) suspension, with SACH foot. Instrumented gait analysis was performed in 30 persons having unilateral transtibial amputation of traumatic origin using either PTB pros...

OBJECTIVE The objectives of this study were to compare the effects of a newly designed magnetic suspension system with that of two existing suspension methods on pistoning inside the prosthetic socket and to compare satisfaction and perceived problems among transtibial amputees. DESIGN In this prospective study, three lower limb prostheses with three different suspension systems were fabricat...

A preliminary investigation was conducted to characterize the magnitude and distribution of volume change in transtibial residua at two time intervals: upon prosthesis removal and at 2 week intervals. Six adult male unilateral transtibial amputee subjects, between 0.75 and 40.0 years since amputation, were imaged 10 times over a 35-minute interval with a custom residual limb optical scanner. Vo...

Despite modern reconstruction techniques and replantation, the preservation of a severely traumatised limb, or even a limb affected by a congenital malformation, usually gives poorer functional results compared with amputation and prosthetisation. The aim of this study was to describe a hind foot (including the calcaneum and fat pad) sensate flap with a surface that allows full terminal weight ...

BACKGROUND AND PURPOSE Osseointegrated implants are an alternative for prosthetic attachment in individuals with amputation who are unable to wear a socket. However, the load transmitted through the osseointegrated fixation to the residual tibia and knee joint can be unbearable for those with transtibial amputation and knee arthritis. We report on the feasibility of combining total knee replace...

Individuals with unilateral transtibial amputations have greater prevalence of osteoarthritis in the intact knee joint relative to the residual leg and non-amputees, but the cause of this greater prevalence is unclear. The purpose of this study was to compare knee joint contact forces and the muscles contributing to these forces between amputees and non-amputees during walking using forward dyn...

Background
 Limb amputations are one of the most devastating injuries for young people in traumatic settings. People with lower extremity loss face challenges performing daily activities and managing life-long complications; thus, rehabilitation prostheses critical improving quality life. This systematic review meta-analysis aims to determine outcomes who had unilateral transtibial transfe...

The effects of Seal-In X5 and Dermo liner (Össur) on suspension and patient's comfort in lower limb amputees are unclear. In this report, we consider the case of a 51-yr-old woman with bilateral transtibial amputation whose lower limbs were amputated because of peripheral vascular disease. The subject had bony and painful residual limbs, especially at the distal ends. Two prostheses that used S...
