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 .
[Results after replacement of femoral neck prostheses - thrust plate prosthesis (TPP) versus ESKA cut prosthesis].
AIM The aim of this study was to analyse and evaluate comparatively loosening mechanisms , failure frequency , surgical changing strategies and results after replacement of  thrust plate prostheses ( TPP ) and ESKA Cut prostheses . METHOD Between 1993 und 2007 , 465 TPP and in the years 2000 and 2001 82 ESKA Cut prostheses were performed and evaluated prospect ively . Until 2007 46 change interventions of the TPP and 35 of the CUT prosthesis became necessary . All patients who received a stem revision procedure in our hospital were included within this study . Besides the evaluation of clinical results according to the criteria of the Harris Hip Score on the average at 15.6 months ( + /- 14.4 ) postoperatively , radiological loosening processes and surgical difficulties were registered . Furthermore , an analysis of perioperative data was performed according to some criteria of the German Federal Office of Quality Assurance ( BQS ) , such as duration of the surgery , intraoperative blood loss and complications . Statistical investigations for comparative analysis as well as survival analysis of both groups were calculated using SPSS for Windows 13.0 . RESULTS The mean age of the 46 patients who had to undergo revision surgery after TPP was 60.1 years , that of 35 patients in whom revision surgery was necessary after receiving an ESKA Cut femoral neck stem was 56.6 years . The survival rate analysis according to Kaplan-Meier at 13 years was 89.4 % ( TPP ) and 53.6 % at 66 months ( ESKA Cut ) . In all cases the partial osteointegration of the tripod surface of the loosened Cut prosthesis complicated the explantation . It led on the one h and to a significant difference of the surgery duration and on the other h and to an increased frequency of fractures of the trochanteric region . The conversion of the TPP on st and ard type stems was usually free of problems . The HHS increased significantly to the averages of 86.6 ( TPP ) or , respectively , 91.69 ( ESKA Cut ) after revision . CONCLUSION In comparison with the usually problem-free changing procedure of the TPP to a st and ard type stem , the revision surgery of the Cut prosthesis becomes substantially more complex and leads frequently to complications . In view of unacceptable survival rates , the Cut prosthesis does not represent an alternative implant in young patients . Except for the implantation technique , which does not allow a less invasive surgical procedure , the TPP fulfils the requirements of femoral neck prosthesis due to acceptable survival rates and good convertibility
