Abstract  

The purpose of  this study is to compare the  clinical and  roentgenographic results  in patients  who have had  implanted  acetabular cup of the THR with use  of the Ortho-Pilot kinematic  CT-free navigation system and without his using. Fifty patients, operated between april 2002 and september 2003, were divided into two groups.  Twenty five patients in group 1. were operated by  standart procedure and   25 patients in group 2. were operated  with use of the  kinematic navigation system.We evaluated both goups roentgenologically  and  clinically. The acetabular cup abduction angle was measured as the angle between the horizontal  line drawn through the interteardrop line and the long axis of the cup ellipsoid. The acetabular cup anteversion was calculated. using the method of Ackland at al.  Clinically evaluation was provided by Merle d'Aubigne and Postel. Both goups were compared statistically. Good acetabular cup position is one of important factor for  the long term good results  of THR. Using of the kinematic navigation CT-free system we see in implantation of acetabular cup  in more accurate position.
