With Sectra Implant Movement Analysis (IMA), surgeons can find out if an implant is loose with the help of a CT scan. Patients who experience chronic pain after an implant surgery can thereby avoid unnecessary risks, such as infections and complications that may be caused by an avoidable surgery, if it turns out that the implant is not loose.
As I see it, IMA is a big step forward in terms of being able to evaluate whether a hip implant is loose before going into the operating room. The method will also be easily accessible since the examination can be performed at the local hospital, while the actual analysis is carried out centrally.
Two images of the patient are taken in a low-dose CT. For patients with back or neck implants, this involves one CT scan in flexion and one in extension. For patients with hip replacements, a CT scan with internal and external hip rotation is required. The images are then sent for analysis by specially trained radiologists through Sectra’s service. Within seven days, the hospital will receive a referral with a statement indicating whether or not the implant is loose. In the case of a loose implant, the referral also includes images where it is possible to see exactly where the implant is moving. This means that the surgeon can immediately see what needs to be addressed.
Sectra Implant Movement Analysis is primarily suitable for patients with hip, spine or neck implants.
IMA is currently sold only in Sweden but will soon be available in other countries.
