The early postoperative phase after transtibial amputation is characterized by rapid residual limb volume reduction. Accurate measurement of residual limb volume is important for the timing of fitting a prosthesis. The aim of this study is to analyze the reduction of residual limb volume in people with transtibial amputation and to correlate residual limb volume with residual limb circumference...

This paper presents the one-dimensional gait kinematic principle, in order to identify the kinematic parameters for normal and pathological (transtibial amputation) gait of two subjects with similar anthropometry. Each type of gait is associated with uniform linear motion and uniformly accelerated motion. We used the Manuela Beltrán University Biomechanics Laboratory. The developed physical mod...

Saito et al. (Modern Plastics 1997;74:175-7) have developed a low-cost transtibial prosthesis made of fiber-reinforced plastic (FRP). The prosthesis is comprised of an aluminum pylon, a cosmetic cover, and a constant cross-section composite foot into which aluminum supports are screwed to increase load-bearing capacity. Replacing these supports with a single integrated FRP stiffener significant...

Disarticulation has been carried out in ten ankles in nine patients in whom it was not possible to use a heel flap. Four patients were able to walk with a prosthesis which gave satisfactory function. In five who were bedridden, healing was achieved and was of sufficient quality to allow transfers. There was no operative morbidity or mortality. This technique can be used instead of a transtibial...

Introduction: Proper fitting of the stump inside the socket and appropriate selection of prosthetic suspension have positive effects on amputees’ satisfaction and could decrease gait deviation, skin problems, and stump atrophy. The suction sockets are commonly prescribed for transtibial amputees to have better suspension compared to the Pin and lock systems. The Seal-In® X5 (suction system) is ...

BACKGROUND The suction sockets that are commonly prescribed for transtibial amputees are believed to provide a better suspension than the pin/lock systems. Nevertheless, their effect on amputees' gait performance has not yet been fully investigated. The main intention of this study was to understand the potential effects of the Seal-in (suction) and the Dermo (pin/lock) suspension systems on am...
