About this study

In all hips, investigators measure femoral stem anteversion postoperatively with three-dimensional computed tomography reconstruction of the femur, using both the distal femoral epicondyles and the posterior femoral condyles to determine the femoral diaphyseal plane. And investigators compare the surgeon's estimate of intraoperative stem version and stem version of CT scan.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Investigators recruited 40 consecutive patients who underwent THR between October 2015 and December 2015

Exclusion criteria

  • patients who could not extend the hip because of a residual flexion contracture.

who had a flexion contracture of the knee or who could not flex the hip to 90° even after THR were excluded because participants could not adopt the posture required for the particular radiographs and CT scans.

intraopertive surgeon's estimation and postoperative CT scan

Primary outcomes

  1. Intraopertive surgeon's estimation and postoperative CT scan were taken to measure stem anteversion

    Time frame: postoperative 4days

Secondary outcomes

  1. The correlation between stem anteversion of intraopertive surgeon's estimation and stem version postoperative CT scan

    Time frame: postoperative 4days

    to determine ICC(intraclass coefficient, correlation coefficient)
