Study summary

The purpose of this study was to develop a radiological method to measure stem anteversion and to determine its validity and reliability.

Read the detailed description

Version of the femoral stem is an important factor influencing the risk of dislocation after total hip replacement (THR) as well as the position of the acetabular component. However, there is no radiological method of measuring stem anteversion described in the literature. Investigators propose a radiological method to measure stem version and have assessed its reliability and validity. In 40 patients who underwent THR, a hip radiograph and CT scan were taken to measure stem anteversion.

Study population

patients who underwent THR between October 2015 and December 2015

Inclusion criteria

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

Exclusion criteria

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.

What researchers measure

Primary outcomes

  1. stem anteversion of the hip radiograph(decubitus lateral view)

    Time frame: postoperative 4days

  2. stem anteversion of the CT scan

    Time frame: postoperative 4days

Secondary outcomes

  1. The correlation between stem anteversion of the decubitus lateral view and stem version of the CT scan

    to determine ICC(intraclass coefficient, correlation coefficient)

    Time frame: postoperative 4days
