About the trial

What the trial wants to find out

The aim of this study is to evaluate a new technique that optimizes the prosthesis position for patients who undergo total hip arthroplasty surgery. Today, most surgeons take a regular X-ray (2D) to plan the surgery. In this study, patients will do a computed tomography (CT) before surgery, and with the use of the new system, the investigators will be able to make a more accurate plan when it comes to prosthetic placement and leg length adjustment in 3D. The software uses artificial intelligence (AI) to generate the information required for clinical conclusions automatically, and it enables surgeons to adapt to each unique case and anticipate situations during surgery. The system also helps the surgeon during operation with a navigation tool to place the implant in the pre-operatively planned position. It guides surgeons in real-time to place the implants accurately. To see whether the plan and navigation were correct, the investigators will do a new computed tomography after surgery to look at the achieved result.

In addition to planning and navigation, the same system can be used to measure the migration of the prosthesis in relation to the bone over time using AI by comparing multiple scans. The investigators aim to follow all patients for 2 years (total of 4 CT scans after surgery) with the intention to be able to foresee implant loosening.
