Accuracy of Combined Anteversion in the Combined Anteversion Technique with Image-free Navigated Total Hip Arthroplasty
In recent literatures dealing with optimization of prosthetic alignment in total hip arthroplasty (THA), the concept of combined anteversion (CA), which is the sum of acetabular anteversion (AV) and femoral antetorsion (AT), has been addressed. Widmer attempted to determine the optimal CA using a computer simulation study . He proposed the “new safe zone” for the CA value to achieve essential r...
متن کاملKyon Cementless Total Hip Arthroplasty
My interest in cementless Total Hip Arthroplasty began in 1993 when I was introduced to the experimental PCA-Howmedica system while visiting Dave De Young at NCSU Veterinary College. After previous experience with cemented prostheses, I was looking for a commercially available cementless system to eliminate the complications I had encountered with cemented hips, mainly aseptic implant loosening...
متن کاملCementless femoral fixation in total hip arthroplasty.
Cementless femoral fixation by means of bone ingrowth has been successful in total hip arthroplasty in patients with sufficient bone quality. Consistent bone ingrowth and resultant long-term success involve many factors, including surgical technique, initial mechanical stability achieved at time of implantation, stem design and material, and implant surface. One potential method for achieving f...
متن کاملCementless Femoral Fixation in Total Hip Arthroplasty
In 1995, the NIH (National Institutes of Health) Consensus Development Panel on Total Hip Replacement supported the use of hybrid fixation with a cemented stem and a noncemented cup because of excellent long-term results. However, today, 60% to 90% of the approximately 200,000 total hip arthroplasties performed yearly in the United States involve both a cementless cup and a cementless stem. The...
متن کاملThe influence of cup anteversion on total hip arthroplasty dislocation mechanisms
[INTRODUCTION] Dislocation continues to be a common complication of total hip arthroplasty (THA). Many in vitro studies have reported the range of motion (ROM) of the hip, impingement, and dislocation mechanism, but the influence of muscle and soft tissue remains little explored. Many factors affect the prevalence of dislocation after THA, including soft tissue laxity, surgical approach, compon...
