Challenges of Plate Fixation for Vancouver Type-C Fractures after a Well-Fixed Hip Arthroplasty Femoral Stem
The fixation of distal femoral fractures (Vancouver type-C fractures) following a well-fixed hip arthroplasty femoral stem has become a challenging issue for orthopedic surgeons due to the inter-prosthetic biomechanical effects such as negative, positive, and torsional strain. Surgeons have applied a range of constructs to overcome these difficulties. To minimize the risk of inter-prosthetic fr...
متن کاملExperimental evaluation of new concepts in hip arthroplasty.
In this thesis we evaluated two different hip arthroplasty concepts trough in vitro studies and numerical analyses. The cortical strains in the femoral neck area were increased by 10 to 15 % after insertion of a resurfacing femoral component compared to values of the intact femur, shown in an in vitro study on human cadaver femurs. There is an increased risk of femoral neck fracture after hip r...
متن کاملBone density study of the proximal femur after hip arthroplasty with porous-coated implants
Progressive loss of bone mineral density around the femora! component of total hip replacement continues to pose a threat to long term prosthetic survival. A linear study was undertaken to measure bone mineral density on a monthly basis following total hip arthroplasty in 11 male patients. The opposite femur was used as the control measurement. Bone mineral density was unchanged at two mo...
متن کاملEffects of material properties of femoral hip components on bone remodeling.
Bone loss around femoral hip stems is one of the problems threatening the long-term fixation of uncemented stems. Many believe that this phenomenon is caused by reduced stresses in the bone (stress shielding). In the present study the mechanical consequences of different femoral stem materials were investigated using adaptive bone remodeling theory in combination with the finite element method....
متن کاملLong-Term Results of Total Hip Arthroplasty with an Extensively Porous Coated Stem in Patients Younger than 45 Years Old
PURPOSE This study analyzed the long-term results of cementless total hip arthroplasty using an extensively porous coated stem in patients younger than 45 years old. MATERIALS AND METHODS The clinical and radiographic results of 45 hips from 38 patients who underwent cementless total hip replacement arthroplasty with an AML prosthesis were reviewed retrospectively. The average follow-up was 1...
