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 .
Bone remodelling after femoral short stem implantation in total hip arthroplasty: 1-year results from a randomized DEXA study
Introduction Short stem prostheses have been developed to preserve proximal femoral bone stock . This prospect i ve , r and omized study compared periprosthetic bone remodelling following short and straight stem implantation 1 year after surgery . Material s and methods One hundred and forty-four consecutive patients undergoing total hip arthroplasty were r and omized to either a Fitmore short or a cementless straight stem ( both Zimmer , Winterthur , Switzerl and ) . Periprosthetic bone mineral density ( BMD ) was measured using dual-energy X-ray absorptiometry performed the day before surgery and at 7 days , 3 months and 1 year postoperatively . Furthermore , the HHS and the WOMAC were obtained . Results One hundred and thirty-eight patients completed 1-year follow-up . Periprosthetic BMD changes at 1 year were most pronounced in the proximal medial region of interest ( ROI ) 7 with −17.2 % after short stem and −16.7 % after straight implantation ( p = 0.67 ) . However , there was significantly less BMD reduction in ROI 6 following short ( −4.7 % ) versus straight stem ( −10.8 % ) implantation ( p = 0.01 ) . There were no significant differences between the two groups in terms of the HHS and the WOMAC either before or after surgery . Conclusion One year after surgery , both stems showed an implant-specific periprosthetic bone remodelling . Nevertheless , proximal load transfer was more pronounced after short stem implantation than with a straight stem
