Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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.
