Implant positioning represents a significant challenge for total hip replacements. Implants need to be well-fitted and positioned within the medullary canal, and should ideally maximize the femoral bone-implant contact area. Experimental testing of implant positions is limited by cost. An alternative is...
HipBackground:Restoration of normal hip anatomy and biomechanics is a key surgical goal for success in total hip arthroplasty. The aim of this study was to evaluate the influence, if any, that patient positioning in the supine and lateral decubitus positions has in achieving this goal. Materials...
We tested the hypothesis that the non-image-based navigation system used in our department was able to measure accurately the 3D positioning of the acetabular cup of a total hip replacement (THR) and to increase the accuracy of its implantation during THR. We studied 50 consecutive navigated imp...
Obesity in total hip replacement Reply A prospective, multi-centre study was carried out on 1421 total hip replacements between January 1999 and July 2007 to examine if obesity has an effect on ... D Beard,D Murray,G Andrew,... 被引量: 0发表: 2009年 Obesity in total hip replacement. ...
Mako Total HipReplacement FIND A SURGEON The Mako Difference Mako Total Hip can help lead to better outcomes, like less pain1and shorter recovery times1, compared to manual surgery. In clinical studies, compared to manual hip replacement surgery, Mako Total Hip demonstrated: ...
The aim of the study was to analyse the results of uncemented total hip replacement, using the Metha (metaphyseal) stem. A total of 158 patients (70 females and 88 males) were qualified to the study and submitted to total hip arthroplasty (183 procedures altogether), using the Metha stem....
Cementless total hip replacement (THR) is rapidly being accepted as the surgery for arthritic diseases of the hip joint. The bone-ingrowth rate in porous-type cementless implants was about 90% over 10 years after surgery, showing that biological fixation of cementless THR was well maintained on ...
The influence of head and neck geometry on stability of total hip replacement. Background Dislocation after replacement may be caused by poor implant design or positioning, or by the surgical approach taken. We evaluated the infl uenc... Bader,Rainer,Scholz,... - 《Acta Orthopaedica Scandinavica...
Cup positioning in total hip arthoplasty: spatial alignment of the acetabular entry planePurpose Correct cup positioning is one of the keys for successful total hip replacement. There are mechanical and computer assistant guides for correct cup positioning in the market. To optimize the cup ...
Advocates of robot-assisted technique argue that robots could improve leg length restoration in total hip replacement. However, there were few studies to compare the robot-assisted posterior approach (RPA) with conventional posterior approach (PA) THA and direct anterior approach (DAA) THA in LLD....
