At the 2019 AOFAS Annual Meeting in Chicago, Dr. Francois Lintz, MD, FEBOT, PhD showcased CurveBeam’s efforts to develop an automatic measurement tool, Smart M1-M2. This tool automatically calculates the intermetatarsal (IMA) angle on a 3D foot & ankle CT scan in a matter of seconds. The validation effort for the Smart M1-M2 tool is being led by Dr. Jonathan Deland, MD at the Hospital for Special Surgery.
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.
In just a little over a week, many of the greatest minds and innovators in radiology will convene in Chicago for RSNA 2016, and we at CurveBeam are proud to have our talented and skilled team there representing us. Over the course of the conference, there will be groundbreaking research presented, technological advances displayed and educational classes offered. In the heart of it all, our booth will be featuring some incredible innovations – proving once again that CurveBeam is continuing to find new ways to push the boundaries of our field.
Our core team pioneered Cone Beam CT imaging technology for the dental and ENT specialties. The ability to provide point-of-care imaging revolutionized these industries and allowed not only for improved care, but for the possibility of custom dental implants. Now we are taking that same breakthrough technology and adapting it to the orthopedic field, and we are proud to introduce the results of our efforts at this year’s RSNA. Here are our top three reasons why you can’t afford to miss the CurveBeam booth this year:
See the LineUp
We will unveil the prototype for the LineUP, a bilateral weight-bearing Cone Beam CT imaging system for the knees and lower extremities. It will not only plugs into a standard wall outlet, but will also be self-shielded and will complete a scan in under a minute. While the technology is still investigational only, it is PACS/ DICOM compliant and is sure to revolutionize the way orthopedic clinics approach radiology.
While the LineUp is certainly fast, the InReach completes scans of the hand wrist, forearm, elbow and extremities in under 20 seconds flat. We designed InReach technology to bring the idea of point-of-care extremity CT imaging to upper extremity specialists. While it is also still investigational technology, the progress we’ve made toward this goal is worth coming to see.
One of the most crucial elements of orthopedic surgical planning is the precise pre-operative measurement of hindfoot realignment. TALAS is a tool that makes the process not only smoother, but more accurate and precise. It is a semi-automated hindfoot alignment measurement device that has been adapted for weight-bearing CT. Come check it out for yourself, and discover the potential TALAS has to one day be a true game-changer in the field.
“We are tremendously excited to share our recent research and development efforts with the global radiology community,” says CurveBeam President and CEO Arun Singh. RSNA is an opportunity to share and learn together as a community and we are thrilled to be a part of that experience. Feel free to come by and discover our innovative new technology.
