Bone Ingrowth on Cementless Femoral Stems – a Comparison Study for Two Stem Geometries
INTRODUCTION: This paper presents a model to predict bone ingrowth on cementless stems after a total hip arthroplasty. The post-operative fixation and the osseous-integration depend on the mechanical stability of the prosthesis. Actually, the micromovements between bone and stem are related to the amount of bone ingrowth on porous surface of the stem. Thus, a model developed for this interface ...
متن کاملAnalysis of bone mineralization on uncemented femoral stems by [18F]-fluoride-PET
PURPOSE We present the first study using fluoride-positron emission CT (F-PET/CT) to analyze mineralization of bone in the femur adjacent to uncemented stems following total hip arthroplasty (THA). We studied patients who were operated bilaterally for osteoarthritis with 2 different stems during the same surgical session. PATIENTS AND METHODS THA was performed bilaterally during the same surg...
متن کاملBone ingrowth into madreporic prostheses.
Three madreporic prostheses in two patients were examined to evaluate resorption and formation of the surrounding bone tissue. All three prostheses were firmly fixed and had no clinical or radiographic signs of loosening. Transverse sections were examined by scanning electron microscopy at 40 days, 11 months and 2.5 years after implantation. The findings suggest that adaptive bone remodelling v...
متن کاملMeasurement of early bone loss around an uncemented femoral stem
BACKGROUND AND PURPOSE Dual-energy X-ray absorptiometry (DXA) is a precise method to study changes in bone mineral density (BMD), including the pattern of bone remodeling around an implant. Results from implant studies are usually presented as changes in BMD as a function of time. The baseline and reference value for such calculations is the first measurement after the operation. The baseline m...
متن کاملPeriprosthetic bone loss after insertion of an uncemented, customized femoral stem and an uncemented anatomical stem
BACKGROUND AND PURPOSE Customized femoral stems are designed to have a perfect fit and fill in the femur in order to achieve physiological load transfer and minimize stress shielding. Dual-energy X-ray absorptiometry (DXA) is regarded as an accurate method for detection of small alterations in bone mineral density (BMD) around hip prostheses. We present medium-term DXA results from a randomized...
