Sectra Implant Movement Analysis

Find out if an implant is loose before surgery

Let's talk

With Sectra Implant Movement Analysis, Sectra IMA, surgeons can more accurately determine whether an implant is loose with the help of two CT scans. This helps surgeons to detect loose implants and pseudarthrosis at an earlier stage and potentially avoid unnecessary surgery. If it is determined that surgery is needed, IMA provides data that enables a better estimate of the surgery time. Ultimately, this results in less suffering for patients and increased efficiency in healthcare.

Detection Find early loosening
Surgery Only revise when needed
Be prepared Know what to expect during surgery

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.

Value based care

Surgeons sometimes encounter inconclusive X-ray findings, leaving them with two difficult choices: either send the patient home or proceed with revision surgery without confirming implant loosening.

However, IMA offers a higher degree of precision—0.2 mm compared to the 4–5 mm detection range of conventional X-rays—allowing problems to be identified far earlier.

This enables surgeons to make more confident decisions about revision procedures and helps prevent unnecessary operations.

In fact, because IMA costs less than 2% of a revision surgery, identifying even one patient out of 40 who does not require surgery can offset its investment.

Beyond detecting implant loosening, IMA provides valuable insights for surgical planning. It clarifies the extent of movement, identifies which part of the implant or bone is moving, etcetera.

Additionally, IMA can determine whether the implant remains securely attached to the cement in cemented procedures—or if the cement is still properly bonded to the bone.

Image Acquisition for Sectra IMA

Radiologists

“Easy to use. Gives relevant and confident clinical information.”

“Good products. Good support. Easy system to use.”

“It is a problem-solving method, and the program is easy to use even though sometimes not all cases are straightforward.”

“Great examination, quite easy to use for radiologists, gives important value to the evaluation of prosthesis stability.”

Orthopedic Surgeons

“Helpful in the decision of making a revision or not.”

“Good interface, scientific background, and proven!”

“Good technique without other similar options for evaluating motion in the spine.”

“The only examination that dynamically assesses whether the prosthesis is loose.”

CT IMA is a promising new technique for diagnostic of loose implants and potentially also for joint instability.

Dr. Stephan M. Röhrl, Head of CIRRO, Proffessor, MD

Key benefits

  • Any hospital with a CT scan can take images for Sectra IMA
  • Offers substantially increased diagnostic precision of detectable movement compared to a standard x-ray (0,2 mm vs 5mm)
  • Offers valuable insight like if the cement is loose from the bone or from the implant, which helps to plan the surgery and avoid surprises.
  • In cases where the implant is not loose, patients can avoid unnecessary, expensive and risky surgeries.
  • Confirming loose implants or pseudarthrosis at an early stage is beneficial for the patient, the surgeon, and the entire healthcare system.
  • The IMA analysis can be used for newly operated patients as well as patients suffering from chronic pain for a long period of time.
