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 .
Changes in bone mineral density in the proximal femur after cementless total hip arthroplasty. A five-year longitudinal study.
We investigated prospect ively the bone mineral density ( BMD ) of the proximal femur after implantation of a tapered rectangular cementless stem  in 100 patients with a mean age of 60 years ( 16 to 87 ) . It was determined using dual energy x-ray absorptiometry , performed one week after surgery and then every six months until the end-point of five years . The BMD increased significantly in Gruen zones 2 , 4 and 5 by 11 % , 3 % and 11 % respectively , and decreased significantly in Gruen zones 1 , 6 and 7 by 3 % , 6 % and 14 % respectively , over the five-year period . The net mean BMD did not change over this time period . The changes in the BMD were not confined to the first 12 months after surgery . This investigation revealed no change in the overall periprosthetic BMD , but demonstrated a regional redistribution of bone mass from the proximal to distal zones
