These studies did not show a satisfactory overall survival rate
Background and purpose The aim of short-stem total hip arthroplasty is to preserve proximal bone stock for future revisions , to improve biomechanical reconstruction , and to make minimally invasive approaches easier .
It is therefore being increasingly considered to be a sound alternative to conventional total hip arthroplasty , especially for young and active patients .
However , it is still unknown whether survival rates of short-stem  hips match current st and ards .
We made a systematic summary of reported overall survival after short-stem total hip arthroplasty .
Stress-related femoral cortical and cancellous bone density loss after collum femoris preserving uncemented total hip arthroplasty: a prospective 7-year follow-up with quantitative computed tomography
Purpose Bone loss around uncemented femoral components is suspected to precede implant loosening and contribute to problems in revision surgery .  Short-stemmed cementless femoral components are design ed to preserve proximal femoral bone stock and ultimately the longevity of the prosthesis . Methods With quantitative computed tomography-assisted osteodensitometry , we prospect ively analyzed femoral cortical and cancellous bone density ( BD ) and contact area changes of an uncemented collum femoris preserving stem ( n = 38 ) 10 days , 1 , 3 and 7 years post-operatively . Results Seven years post-operatively  , cancellous BD ( mg CaHA/mL ) had decreased by as much as −66 % and cortical BD by up to −27 % at the metaphyseal portion of the femur ; the decrease was progressive between the 1- and 3-year examinations and halted thereafter . Contact area ( in % out of a possible 100 % ) decreased proximally between the 1- and 3-year follow-up . Conclusion Proximal cortical and cancellous bone density loss and decrease of contact area indicate that metaphyseal fixation can not be achieved . The lack of cortical BD loss and increase of contact area values below the trochanter minor suggest diaphyseal fixation
