Evaluation of a Software to Predict the Postoperative Component Position in Total Hip Arthroplasty (THA)

Evaluation of a Software to Predict the Postoperative Component Position in Total Hip Arthroplasty (THA): Accuracy of Predictions and Impact on Interoperative Placement in a Single Centre

The goal of this observational study is to learn about the accuracy of a software determining the implant position during THA surgery.

Measurements made with the software are compared to reference values determined on X-rays.

The software is based on comparing an pre-operative fluoroscopy-based image with inter-operative fluoroscopy-based image. Three numerical values are provided: "leg length", "lateral offset" and "inclination".

Correponding reference values are determined based on pre-operative and post-operative X-rays.

Inclusion Criteria:

1. Scheduled for THA
2. Age of 18 or above

Exclusion Criteria:

1. Patients with anatomical conditions which reduce the applicability of the software
2. Patients with implants which reduce the applicability of the software
3. Patients who cannot perform an upright X-ray
