Periprosthetic 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...
متن کاملAn Uncemented Spreading Stem for the Fixation in the Metaphyseal Femur: A Preliminary Report
Surgical treatment to restore full range of motion and full weight bearing after extensive femoral bone resection in patients with primary or metastatic femoral tumours is individually challenging. Especially when the remaining distal or proximal bone is very short, a rigid fixation of an implant is difficult to achieve due to the reverse funnel shape of the metaphysis. Herein, we present a nov...
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 کاملLower periprosthetic bone loss and good fixation of an ultra-short stem compared to a conventional stem in uncemented total hip arthroplasty
BACKGROUND AND PURPOSE We hypothesized that an ultra-short stem would load the proximal femur in a more physiological way and could therefore reduce the adaptive periprosthetic bone loss known as stress shielding. PATIENTS AND METHODS 51 patients with primary hip osteoarthritis were randomized to total hip arthroplasty (THA) with either an ultra-short stem or a conventional tapered stem. The ...
متن کاملSalvage of failed trochanteric and subtrochanteric fractures using a distally fixed, modular, uncemented hip revision stem
BACKGROUND AND PURPOSE Treatment options for failed internal fixation of hip fractures include prosthetic replacement. We evaluated survival, complications, and radiographic outcome in 30 patients who were operated with a specific modular, uncemented hip reconstruction prosthesis as a salvage procedure after failed treatment of trochanteric and subtrochanteric fractures. PATIENTS AND METHODS ...
