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 .
Bone sparing surgical options for total hip replacement.
Between 4/5/99 and 5/20/2002 , our university performed 31 total hip arthroplasties in 27 young patients utilizing a conservative hip prosthesis developed at the Mayo Clinic . Eleven patients underwent Bipolar replacement , while the remaining twenty required an acetabular component . The patients ranged in age from 25 to 50 ( mean of 39.9 ) . The mean follow up was 12.4 months ( range 4.5 - 27 ) . Twenty-eight hips were treated for AVN secondary to RA , HIV , ETOH abuse , and SLE ; while two underwent THA for OA secondary to trauma , and one for JRA . Three patients were lost to follow up at less than 6 months and were excluded from the study . The patients were followed for a minimum of 6 months utilizing the  Harris hip score  , the  Charnley hip score  , and  radiographic evaluation including subsidence , radiolucency , and calcar resorption . Four patients ( 13 % ) had subsidence ranging from 1 to 3 mm at the most recent visit . One patients ( 3.2 % ) had radiographic evidence of radiolucency measuring 2 mm . Nine patients ( 29 % ) developed 1 - 3 mm of calcar resorption . No hips required revision . Thirty patients had improvement in their Harris hip score and Charnley hip score . The one patient who decreased his score had developed AVN secondary to ETOH abuse . Three hips had an intra-operative complication of lateral cortex penetration and required circlage wiring . Comparisons were made utilizing Multiple Logistic Regression to determine if preoperative BMI , Dorr score , and gender had an impact on the postoperative hip scores or degree of osteolysis , subsidence , and calcar resorption . Although the Harris hip score and Charnley hip scores significantly improved postoperatively , the preoperative BMI , Dorr score , and gender did not correlate with patient outcome . Our patients improved clinical ly in pain level , function and ROM . Further follow up will reveal if this component truly preserves bone stock for ease of future revision
