Sectra Implant Movement Analysis

Find out if an implant is loose before surgery

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.

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.

Per Wretenberg, Professor of Orthopaedics at Örebro University Hospital

How it works

Two images of the patient are taken in a low-dose CT. For patients with hip replacements, a CT scan with internal and external hip rotation is required. For patients with spine implants, one CT scan in flexion and one in extension are required. Specially trained radiologists then analyse the images.

The IMA analysis will answer the question if there is 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 or spine implants.

IMA is currently available in the following countries: Sweden, Denmark, Norway, Iceland, USA, UK and The Netherlands.

Key benefits

  • Supports the orthopaedic surgeon when deciding if surgery will help the patient.
  • The IMA analysis can be used for newly operated patients as well as patients suffering from chronic pain for a long period of time.
  • If an implant is confirmed to be loose, the orthopaedic surgeon can use the referral and the images included when planning the surgery.
  • In cases where the implant is not loose, patients can avoid unnecessary and risky surgeries.
  • Avoiding unnecessary surgeries saves resources for the hospital.
