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 .
Reproducibility of femoral offset following short stem and straight stem total hip arthroplasty.
Bone stock-preserving short stem prostheses have gained importance in  total hip arthroplasty ( THA ) with the use of minimally invasive surgical procedures . Because of their metaphyseal fixation and their dependency on the calcar radius , it is unknown whether the femoral offset can be reproduced with the same accuracy following short stem vs st and ard stem THA . This study clarifies whether it is possible to restore the femoral offset using a short stem prosthesis ( Fitmore ; Zimmer , Warsaw , Indiana ) compared with a conventional straight stem prosthesis ( CLS ; Zimmer ) following minimally invasive implantation using an anterolateral approach . In a prospect i ve , r and omized , double-blinded study , 80 patients underwent THA using a short stem ( SS group ; n=40 ) or CLS implant ( control group ; n=40 ) . Follow-up examinations were conducted 6 weeks postoperatively . Radiological and functional outcomes were measured . Subjective assessment of quality of life was evaluated using the Harris Hip Score ( HHS ) , the Short Form 36-item health survey ( SF-36 ) , and the Western Ontario and McMaster Universities Osteoarthritis Index ( WOMAC ) . Pre- and postoperative comparison of the groups ' change in offset showed no significant differences ( SS group difference from pre- to postoperative , 6.1±6.5 mm ; control group difference from pre- to postoperative , 6.5±7.1 mm ; P=.93 ) . Group comparison after 6 weeks revealed no significant differences in HHS , SF-36 , or WOMAC . Based on these data , an equivalent reproducibility of the femoral offset was demonstrated following short stem and straight stem THA using a minimally invasive anterolateral approach . If the long-term results of short stems show a comparable survival , they represent a sensible alternative to st and ard stems
