Edge loading can negatively impact the biomechanics and long-term performance of hip replacements. Although edge loading has been widely investigated for hard-on-hard articulations, limited work has been conducted for hard-on-soft combinations. The aim of the present study was to investigate edge loading and its effect on the contact mechanics of a modular metal-on-polyethylene (MoP) total hip ...

Determining the dynamic response of frozen soil is important for the study of the deformation, strength and stability of frozen soil under dynamic loading conditions for engineering design in cold regions. This paper discusses the recent progress in research on the dynamic response of frozen soil from the following three aspects: (1) influence of various testing conditions (confining pressure, ...

Background Off-loading of plantar pressure is a key intervention strategy to prevent the formation of or to heal existing neuropathic plantar ulcers in diabetes. Walking casts (e.g. total contact cast) that reduce plantar pressures are currently considered the gold-standard for treating such neuropathic ulcers. However, alternative methods for off-loading that are as effective, but cheaper and ...

The purpose of this study was to compare the subjective perceptual responses to both head-loading and back-loading in a group of Xhosa women. Thirty two women were divided into three groups based on their experience of head-loading and walked on a treadmill on two occasions, head-loading and back-loading, at a self selected walking speed for 4 min with a variety of loads until pain or discomfor...

present work shows the numerical determination of fatigue crack opening and closure stress intensity factors of a C(T) specimen under variable amplitude loading using a finite element method. A half compact tension C(T) specimen, assuming plane stress constraint was used by finite element method covering the effects in two-dimensional (2D) small scale yielding models of fatigue crack growth und...

An assessment of the material properties of three types of touch and close fasteners (Velcro) in general orthopaedic usage is presented. The materials were tested under various loading regimes using an Instron testing machine. The force-extension curves were analyzed and values determined for both the stiffness and strength of the various attachments. Particular reference was made to the altera...
