Sectra CT-based Micromotion Analysis

Simplify and speed up the process of validating new orthopaedic implants in vivo

Sectra’s CT-based Micromotion Analysis (CTMA) simplifies and speeds up the process of validating new orthopaedic implants in vivo. CTMA uses CT images taken up to one or two years after implantation to measure 3D motion of an implant or bone fragment on a submillimeter scale. This information provides the surgeon and implant manufacturers with a strong predictor of the long-term survival of the implant.

Easy and fast workflow

When using CTMA in clinical trials, you simply use standard CT and low dose protocol when acquiring the images. CTMA requires no specialized imaging equipment and is therefore a simple procedure for staff to follow. The tool can be used on most implant models without any need for special marking of the implants or bone. The surgeon can use the CTMA system to generate accurate data that can be used to analyze the movement of an implant or bone segment over time, or under load.

Advantages of a CT-based system

The system can be used for trials of new implants as well as for research projects aimed at improving the outcome of existing implant technology, design and surgical techniques. Since standard CT equipment can be used, it is easy to acquire patient images and gather patient data from different hospitals.
