CurveBeam Plays an Important Role in the Best Research Awards at the EFAS Congress

Dr. Francois Lintz posted about being nominated for best research award at EFAS 2018 and congratulated Dr. Cesar de Cesar Netto for winning the award with his paper on Weight Bearing CT.

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.

Weight Bearing CT Imaging for Cuboid Subluxations

Dr. Michael Chin, DPM, presented how weight bearing CT imaging has changed how he evaluates cuboid subluxations at the American Academy of Podiatric Sports Medicine meeting held near the West Point Military Academy campus in early September, 2015.

Dr. Chin began using the pedCAT in his office in February of this year.

Not much research is out there on how to use plain radiographs to measure cuboid subluxations, Dr. Chin said in his lecture, titled, “Cuboid Syndrome…The Other Side of Heel Pain.”

Dr. Chin has tested using a bilateral oblique projection to understand the cuboid/ metatarsal relationship, and has been able to observe a slide between the head of the fourth metatarsal and the head of the cuboid.

An MRI could be ordered to see the condition of the peroneal tendon, but the study would be limited because the scan would not be weight bearing, he said.. A traditional CT scan would provide great  visualization of the bone, but would provide no information on anatomic alignment.

The pedCAT weight bearing CT imaging system is excellent for evaluating stress fractures, sesamoids, periosteal changes, or anything medullar, Dr. Chin said. Another benefit is he can measure the exact degree of subluxation between the cuboid and the fourth metatarsal head.

Dr. Chin displayed pedCAT images depicting  pre and post-reduction views of a cuboid subluxation.

pedCAT: Fracture & Fusion Assessments

X-rays of the foot and ankle may not always provide conclusive assessments for post-operative fusions such as of the tarso-metatarsal joint or hind foot joints. Similarly, the physician is often left guessing if a fracture has properly healed.

“The pedCAT takes all the variability out, all the guesswork out of it,” Dr. Martin O’Malley, MD, an Associate Attending Orthopedic Surgeon at the Hospital for Special Surgery in New York, New York, said.

Dr. O’Malley said pedCAT scans allow him to clearly determine if a fusion has healed more than 50 percent, and he decides when to ambulate his patient accordingly.

“I let people walk on it earlier than before, and I keep them off longer than before,” Dr. O’Malley said.

The pedCAT provides a three-dimensional view of fractures that changes the way O’Malley sees this common diagnosis.

“These posterior pieces are often bigger than we thought were based on plain X-ray and they often travel all the way around the medial side as well, which we never thought they did,” Dr. O’Malley said. “You know, we thought it was an infrequent fracture, but now we see it routinely. Now most of my ankle fracture work, I’d say more than half the time, is through a posterior approach. For the first 15 to 18 years of my practice I would do medial/ lateral incisions. Now I’m going to the back of the ankle. And a lot of it is driven by the pedCAT.”

It’s an exciting time at CurveBeam. Almost two years ago  we received FDA-approval for our first product, the pedCAT. The in-office 3D weight bearing imaging system for the foot and ankle has been integrated into orthopedic and podiatric practices around the world.  Foot and ankle specialists, considered leaders in their field, have told us that the pedCAT will become the standard of care for lower extremity imaging in the near future. In fact, in some of their practices, it already is.

We’re dedicated to continuing the improvement of foot & ankle imaging and are excited to share with you the technology advancements, right here on this blog in the upcoming months. So check back often!
