Biomedical Engineer Presents Important Findings on the Responsiveness of Standing CT for Measurement of Knee Joint Space Narrowing at IOWAI 2018

image1

Imaging is a critical tool in the diagnosis and management of osteoarthritis. The International Workshop on Osteoarthritis Imaging (IOWAI) was created to offer opportunities for osteoarthritis investigators to discuss issues and share findings related to imaging. This Workshop was first held in Ainring, Germany in 2017 and is now held annually at various locations in Europe and North America. This year’s IOWAI will be held in Menton, France, on July 5-8. Thought leaders and influencers from academia, regulatory and funding agencies, and the medical equipment industry will be in attendance.

Kaitlin Rabe, Biomedical Research Assistant at the University of Kansas Medical Center, will be presenting a poster titled, “Responsiveness of Standing CT for Measurement of Knee Joint Space Narrowing Over 60 Months.” The study was sponsored by the National Institutes of Health, the University of Iowa, and the University of California, San Francisco.image2

In the workshop, Ms. Rabe will discuss the limitations of two-dimensional radiography when measuring joint space width (JSW). These 2D weight-bearing radiographs traditionally suffer from poor sensitivity when used to detect knee osteoarthritis and produce poor correlation with symptom progression.

Much of these issues can be attributed to the inherent limitations in the 2D radiography procedure, such as the dependence on X-ray beam alignment with the medial tibial plateau. In addition, the temporal and spatial heterogeneity of structural progression of knee OA limits the responsiveness of radiographic JSW to diagnose disease progression. MRI offers important advantages over 2D radiography, but is typically non-weight-bearing.

Standing CT (SCT) imaging holds the potential to overcome these limitations and enhance responsiveness in three-dimensional JSW measurements. This is because JSW is measured in a loaded position while avoiding bony overlap and error due to beam angle variations.

In her workshop, Ms. Rabe will provide preliminary data for the responsiveness of 3D JSW on SCT over 60 months using an early prototype of the CurveBeam LineUP system. The LineUP is a compact, ultra-low dose Cone Beam CT imaging system specifically designed for the orthopedic and podiatric specialties. Preliminary data calculated for 33 knees from 19 participants over 60 months support the hypothesis that 3D JSW exhibits a greater responsiveness than has been reported for radiography, similar to that for quantitative cartilage thickness measured on MRI over 12-months.

To get all the details on this important study, be sure to attend Ms. Rabe’s workshop at the IOWAI in Menton, France, July 5-8. For more details on accommodations and the all the workshops at this important conference, go to https://www.iwoai.org/.

The Weight-Bearing CT International Study Group, Brought to You by CurveBeam

This year CurveBeam will be co-sponsoring the Weight-Bearing CT International Study Group Thursday, July 12, 5:00-6:30 PM at the Hynes Convention Center, Room 310, in Boston, MA.

Dr. Martinus Richter from Krankenhaus Rummelsberg will be moderating a panel of experts from around the world. Professor Alberto Leardini from the Rizzoli Institute, Dr. Francois Lintz from Clinique de L’Union, Dr. Cesar de Cesar Netton from the Hospital for Special Surgery, and Dr. Alastair Younger from the Footbridge Centre for Integrated Orthopedic Care will join and discuss the latest thinking in weight-bearing CT.

The goal of the study group is to promote dialogue and collaboration on weight-bearing CT research, as well as create standardizations for weight-bearing CT measurements and analysis.

Weight-bearing CT scans use low doses of radiation while creating an image of the foot and ankle while the patient is standing in a natural standing position. Having patients in a natural standing position is beneficial for doctors because they can see the bones and tendons of the foot and ankle under normal conditions. Patients with pain and deformities seem to benefit most from using weight-bearing CT scans.

While many years of research have shown the benefits of these types of scans, we know there are many out there who still have questions. This International Study Group will provide you with answers. We would also love to have orthopedics and podiatrists with experience with weight-bearing CT to join us and share your own experiences with the technology.

Anyone interested in learning more about weight-bearing CT, including the Cone Beam CT imaging equipment for orthopedics and podiatrists designed by CurveBeam, is invited to join us for presentations from these experts.

Space is limited. RSVP today at wbctstudygroup.com!

Weight-Bearing CT May Improve Diagnoses in Hallux Valgus Patients

Hallux Valgus

A recent analysis of studies titled Imaging of Hallux Valgus by James Welck and Naji Al-Khudairi has shown that newer, three-dimensional imaging techniques including weight-bearing computer tomography (WBCT) may permit a more thorough understanding of the hallux valgus (HV) deformity and provide greater information to foot and ankle surgeons prior to corrective surgery.

Traditional two-dimensional AP, lateral, and oblique radiographs are the current standard for imaging HV deformity. Two-dimensional radiographic images can be used to measure several radiographic angles which are commonly used to quantify the extent of HV deformity. However, recent research shows that some of these angle measures show low levels of reliability and accuracy. Coughlin et. al. found that measures of the hallux valgus angle and the intermetatarsal angle assessed using 2-D imaging had high intraobserver and interobserver reliability. In contrast, the distal metatarsal articular angle was measured to 5° or less in only 58.9% of cases, and measurement of metatarsophalangeal joint congruency led to a wide variation in cases identified. The primary reason that two-dimensional imaging techniques may fail to be reliable is that HV is a triplanar deformity with rotational aspects that two-dimensional images cannot account for.

Fortunately, research shows three-dimensional HV imaging techniques have promise. Conventional CT imaging is not weight-bearing, but weight-bearing cone beam CT provides better insight into HV. This means that many patients imaged through traditional CT may not have been diagnosed correctly.

  • Welck and colleagues have found WBCT to better display the sesamoids, which are difficult to represent accurately using traditional AP radiographs.
  • Collan and colleagues demonstrated the importance that CT is weight-bearing by finding that there were significant differences in HVAs and IMAs between HV and control groups only when patients were in a weight-bearing stance.

Two other research groups found that WBCT provided insight into the effects of joint hypermobility in HV patients which would not typically be measurable using two-dimensional imaging techniques.

CurveBeam’s PedCAT systems are at the cutting edge of WBCT innovation and can help provide your patients with the best HV care that current science has to offer.
