Do hip-abduction braces work?—A biomechanical evaluation of a commercially available hip brace

immediate effect of hip abduction brace on mobility and functional balance of total hip replacement

background and aim: total hip replacement (thr) is done comprehensively all over the world. despite the effects of braces on control of thr complications , few studies have been performed on this subject. the purpose of this study was to evaluate immediate effect of hip abduction brace on mobility and functional balance of patients with thr.    materials and methods: eight men and nine women wi...

Visual grading evaluation of commercially available metal artefact reduction techniques in hip prosthesis computed tomography.

OBJECTIVE To evaluate metal artefact reduction (MAR) techniques from four CT vendors in hip prosthesis imaging. METHODS Bilateral hip prosthesis phantom images, obtained by using MAR algorithms for single-energy CT data or dual-energy CT (DECT) data and by monoenergetic reconstructions of DECT data, were visually graded by five radiologists using 10 image quality criteria. Comparisons between...

Hip Abduction Can Prevent Posterior Edge Loading of Hip Replacements

Edge loading causes clinical problems for hard-on-hard hip replacements, and edge loading wear scars are present on the majority of retrieved components. We asked the question: are the lines of action of hip joint muscles such that edge loading can occur in a well-designed, well-positioned acetabular cup? A musculoskeletal model, based on cadaveric lower limb geometry, was used to calculate for...

Hip Muscle Activity during Isometric Contraction of Hip Abduction

[Purpose] This study aimed to determine the effect of varying hip flexion angle on hip muscle activity during isometric contraction in abduction. [Subjects] Twenty-seven healthy men (mean age=21.5 years, SD=1.2) participated in this study. [Methods] Surface electromyography (EMG) was recorded of the upper portion of the gluteus maximus (UGM), lower portion of the gluteus maximus (LGM), tensor f...
