Abstract：Objective To investigate the recovery and reconstruction of the eccentric distance in total hip arthroplasty ( THA) ,and to analyze the relationship between the eccentric distance and the hip joint function recover -y.Methods Ninety-eight patients treated with unilateral THA from Jan .2008 to May.2012 were randomly selected in our hospital .Posterior lateral approach of hip joint was used .Depuy ( Pinnacle Acetabular System ) and Corail were applied in all patients .Imaging examinations were taken before and after surgery:X ray film of the front and rear pelvis,the three-dimensional CT scan of the hip joint ,X ray film of the double lower limbs .The full length of the two legs,the length of the femoral eccentricity ,the length of the white space ,the eccentricity and the other inde-xes of the eccentric distance and their relationship was analyzed .Results All 98 patients were involved in the re-sult analysis.(1)The hip joint eccentricity and the hip abduction torque was positively correlated (r=0.558,P<0.001).(2)The eccentric distance and Harris hip score had obvious regression correlation (r=0.439,P<0.001). (3)The reconstruction of the hip joint eccentricity had a significant effect on the length of the two legs (χ2 =4.83, P<0.01).Conclusion The reconstruction of the eccentric distance of THA can increase the torque of the hip joint and the activity of the hip joint ,which is positively related with the function improvement and increased stability .
