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

Eligibility Criteria
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.
Outcomes
Primary Outcomes
stem anteversion of the CT scan
Time Frame: postoperative 4days
stem anteversion of the hip radiograph(decubitus lateral view)
Time Frame: postoperative 4days
Secondary Outcomes
- The correlation between stem anteversion of the decubitus lateral view and stem version of the CT scan(postoperative 4days)
