Brief Summary

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

This study used 3D reconstructions from the EOS biplanar radiographic imaging system to perform leg length measurements before and after THA (Total hip arthroplasty) on all included THA patients from 2015 to evaluate surgeon performance in restoring lower limb length after THA and the relationships between the quality of life, estimated by the HOOS score (Hip disability and osteoarthritis outcome score), and the anatomy of the new hip in standing position.

Detailed Description

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

The study was conducted in patients who underwent a total hip arthroplasty in Lariboisiere Hospital, Paris, France, during the year 2015.

This retrospective study used 3D reconstructions from the EOS biplanar radiographic imaging system (EOS imaging, Paris, France) to perform leg length measurements before and after THA on all included THA patients from 2015 to evaluate surgeon performance in restoring lower limb length after THA. Included patients either had hip osteoarthritis or femoral head osteonecrosis. Patients were excluded if they were undergoing revision surgery, or had a contralateral THA or total knee.

The performance of the surgeons was judged using the Cumulative Sum control chart (CUSUM) method.

Our objective was to study surgeon performance, measured by their ability to restore the initial preoperative length of the operated leg or to equalize the length of the two legs, and evaluate the relationships between the quality of life, estimated by the HOOS score, and the anatomy of the new hip in standing position using the EOS imaging system.
