The Weight-Bearing CT Society held its latest Scientific Meeting in Las Vegas this past March during the AAOS 2019 conference. Co-sponsored by CurveBeam, the Scientific Meeting featured an education-packed agenda to discuss the revolutionary transformation weight-bearing technology is having on the imaging industry.
First to present was Dr. Alexej Barg, MD, a University of Utah orthopedic surgeon who also served as the moderator for this event. In his presentation discussing imaging of patients with syndesmosis instability, Dr. Barg explained that conventional non-weight-bearing radiograph imaging cannot predict syndesmotic injuries reliably. And while MRI’s demonstrate sensitivity and specificity of nearly 100%, correlating patient complaints with MRI findings can be difficult. Further, although CT technology surpasses conventional imaging methods when 3D MRI or CT imaging is transferred to 2D, there is a substantial loss of information. However, the torque applied in the natural standing position offered higher contrast and spatial resolution of alignment and degeneration, providing a significant advantage in the accuracy of diagnosing syndesmotic injuries.
Dr. Pablo Wagner, MD, of Clinica Alemana in Chile then took the stage for a presentation titled “WBCT for Assessment of Metatarsal Rotation”. Crediting his brother, Emilio Wagner, MD, for his work with hallux valgus patients, Dr. Wagner explained that metatarsal condyles are visible laterally if pronated, of which 87 percent of hallux valgus cases are. If not corrected, metatarsal pronation will result in worse clinical outcomes and higher deformity relapse rates due to the soft tissue balance lateral to the medical ray axis. However, when compared to challenging, unreliable weight-bearing axial sesamoid views and more useful AP foot weight-bearing views on plan X-Ray, weight-bearing CT scans are the gold standard in quantifying metatarsal rotations.
Following Dr. Wagner, Dr. Cesar de Cesar Netto, MD, Ph.D., discussed “WBCT in Patients with AAFD”. While some symptoms or pain are experienced in patients with Adult-Acquired Flatfoot Deformity, it can be difficult knowing when to be more aggressive in treatment to prevent foot collapse. In a study of 55 male and female patients with stage II AAFD, multiple weight bearing CBCT and MRI variables related to the severity of the deformity were evaluated. Weight-bearing CBCT was found to provide more reliability in predicting patients at high risk for foot collapse.
Dr. Arne Burssens, MD, of the Univesity Hospital of Ghent then deliberated on the “Hidden Aspects of a Medializing Calcaneus Osteotomy Revealed by a WBCT”. Difficult to assess via 2D plain radiographic technology, there is a significant difference when assessing MCO in AAFD using weight-bearing imaging versus non-weight-bearing, offering substantial detail to improve understanding with a higher rate of reliability.

The 12th annual European Foot and Ankle Society (EFAS) Congress was recently held in Geneva. As a part of this prestigious event, Dr. Cesar de Cesar Netto and Dr. Francois Lintz presented papers that were both nominated for research awards. CurveBeam is proud to have played a part in both of these important projects.
Dr. Cesar de Cesar Netto Wins Awards for Research and Best Oral Presentation
Dr. Cesar de Cesar Netto, Clinical Fellow of Foot and Ankle Surgery at MedStar Union Memorial Hospital, was nominated and won a distinguished research award for his paper titled, “Weightbearing CT and MRI findings of Stage II Flatfoot Deformity: Can We Predict Patients at High-Risk for Foot Collapse?” Earlier in the year, he also won the best oral presentation at the FLAMeCiPP meeting, organized by the Latin American Foot and Ankle Federation.
Dr. de Cesar Netto’s research involved the prediction of soft tissue failure using weight bearing cone beam computed tomography (WBCT), an imaging modality that allows excellent evaluation of the relative three-dimensional positioning of the tarsal bones in dynamic deformities such as Acquired Adult Flatfoot Deformity (AAFD). The study indicated that WBCT can predict ligamentous injuries and dynamic bone deformity in AAFD patients.
Dr. Francois Lintz was Nominated for his Research
Dr. Francois Lintz an orthopedic Surgeon specializing in Foot & Ankle Surgery in Toulouse, France, was also nominated for a research award for his paper, “3D Biometrics: A Prospective Comparative Evaluation of the Foot Ankle Offset Using Weight Bearing CT Semi Automatic Software.” The objective of Dr. Lintz’s study was to prospectively assess the clinical relevance and reproducibility of the Foot and Ankle Offset (FAO) value for hindfoot alignment, which requires WBCT for measurement, and compare it with previous findings. The study concluded that hindfoot alignment can be measured reliably using WBCT and demonstrated that FAO has good repeatability, and correlates well with clinical examination, 2D findings, and previous literature.
The EFAS Congress
The EFAS Congress provides a platform for professionals of all disciplines dealing with foot and ankle surgery and research to share their knowledge and advance the specialty. This year’s program, themed “State of the Art Foot and Ankle Surgery,” included a line-up of internationally renowned surgeons and scientists in the foot and ankle community. For this year’s gathering, the EFAS also invited representatives from two established national foot and ankle societies—the SFAS (Swiss Foot and Ankle Society) and the KFAS (Korean Foot and Ankle Society)—to share their expertise and innovative approaches in foot and ankle pathologies and treatments. The result was a program that provided a multidisciplinary, comprehensive overview of the latest scientific and clinical findings in foot and ankle surgery, state of the art surgical techniques, biomechanics, efficient conservative treatments, and the most recent imaging modalities in the field.

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.
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/.
