CoCrMo Cemented Hip Stem Harmony Hip Replacement Artificial Hip Joint

Description :

- cemented femoral stems probably remain gold standard for total hip arthroplasty;

- most indicated in older patients (more than 65 yrs), but are also used in younger patients since there is some indications that cemented stems are less prone to develop osteolysis;

- useful for patients w/ "stove pipe" type femur, previous fracture, or previous osteotomy since these patients would not be expected to achieve a tight fit which is necessary for ingrowth;

- may be indicated poor bone quality such as RA, osteoporosis, or Paget's disease;

- Harrington MA, et al, the authors determined that in a stair-climbing test model, the peak proximal cement strains were increased more by changes in body wt than they were by changes in neck length. Even during stair-climbing, calcar-collar contact reduced peak cement strains;

- peak strain magnitudes in proximal cement mantle were increased more by changes in body wt than by changes in length of neck of stem;

- strong effect of stem size on the cement strains suggests that cemented femoral stems should not be used in heavy patients with small medullary canals that require a small cemented stem;
