An observational study in Total Hip Arthroplasty, sponsored by Marcel Jakob. Not yet recruiting. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-08-06.
Sponsored by Marcel Jakob · Observational
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.
This is the only study on the registry with Marcel Jakob as lead sponsor.

Patients undergoing total hip arthrosplasty
Exclusion Criteria:
All patients included in the study
Device: MyHip Verifier
Numerical information on the position of the implant is provided to the surgeon.
Mean absolute difference between measured value and reference value
The mean absolute difference between the final value measured by the software and the reference value determined on a postoperative X-ray.
Time frame: This measure involves two time points: Stopping of the software during surgery and performing the postoperative X-ray. The latter is usually the first day after surgery. A delay is allowed if a patient cannot perform an upright X-ray.
Mean amount of repositioning performed by the surgeon
The mean absolute difference between the value measured by the software when started and the final value
Time frame: This measure involves two time points: Starting and stopping of the software during surgery.
Mean absolute improvement in reaching the target value
The mean value of the change in absolute difference between the actual position and the target value from starting the software until stopping the software.
Time frame: This measure involves three time points: Determining target values prior to surgery and starting and stopping the software during surgery,
