Our results suggest that compared with CS , SS may provide superior bone remodelling and similar survival rates and clinical outcomes .
However , the short-term follow-up of the included studies was inadequate to determine the long-term performance of SS
OBJECTIVE Cementless total hip arthroplasty (  THA ) is associated with reliable clinical results and high patient satisfaction .
Short-stem prostheses ( SS ) were design ed to achieve superior preservation of proximal bone stock and stability compared with those of conventional-stem prostheses ( CS ) .
This meta- analysis was conducted to determine the proximal bone remodelling , revision rate , Harris Hip Score , radiolucent line and maximum total point motion values of both SS and CS for primary THA .
Comparison of two hydroxyapatite-coated femoral stems: clinical, functional, and bone densitometry evaluation of patients randomized to a regular or modified hydroxyapatite-coated stem aimed at proximal fixation.
Clinical function , bone mineral density ( BMD ) , and radiographs of 80 r and omly allocated , hydroxyapatite-coated femoral stems of two differing lengths  were studied for 2 years . The short stem was optimized for proximal fixation . The predictive value of bone densitometry was also studied . After 2 years , significantly more bone apposition and a higher BMD percentage were observed in Gruen zone 7 of the short stem . We conclude that stem design can be enhanced to achieve more proximal fixation . However , we found a higher incidence of pain with the short stem , indicating a trade-off between increased proximal fixation and diminished overall mechanical stability . No strong correlations between clinical function and radiographic evaluation of remodeling were found with BMD , suggesting that dual-energy x-ray absorptiometry has no predictive value for short-term clinical outcome
