The posterolateral approach reported the lowest value for the surgical duration .
The posterolateral approach reported the shortest hospitalization length .
The posterolateral approach reported shorter surgical duration and hospitalization length .
Concerning the analysis of total estimated blood loss , no significant result was obtained .
Despite the numerous studies , there is no consensus concerning the best approach for  total hip arthroplasty ( THA )  , and debates are ongoing .
The purpose of this study was to perform a Bayesian network meta- analysis ( NMA ) comparing several approaches for primary THA .
The focus was on peri-operative outcomes : surgical duration , total estimated blood loss , and length of the hospitalization .
[Minimally invasive posterior approach for total hip arthroplasty].
The mini-posterior approach for total hip arthroplasty ( THA )  belongs to the mini-incision approaches . In comparison to st and ard approaches , less muscle trauma result ing in less pain , less blood loss and faster rehabilitation in the early postoperative period are attributed to this approach , as known for all other minimally invasive approaches . In a prospect i ve study of 100 cases of THA it could be shown that this is true when comparing the mini-posterior approach with the posterolateral approach . Lower levels of muscle enzymes as a parameter for muscle trauma , could not be seen
