IFFAS Award of Excellence Goes to Study Using Weight Bearing CT to Examine Residual Effects of Misalignment in TAR Patients

An international research team of orthopedic surgeons was awarded the prestigious International Federation of Foot & Ankle Societies (IFFAS) Award for Excellence for a study that utilized weight bearing CT imaging  to analyze the effect of residual misalignment on cyst formation in total ankle replacement (TAR) patients.

The award was presented to the researchers at the American Orthopedic Foot and Ankle Society (AOFAS) Annual Meeting in Chicago on September 14 .

The authors hypothesized that longer follow-up and increased residual misalignment would correlate with increased peri-prosthetic cyst (PPC) volume and worse AOFAS scores. They found that residual varus cases had a more medial distribution of PPC and residual valgus cases had a more lateral distribution of PPC. During a presentation the next day, the authors explained that a using weight bearing CT to calculate a “Safe Zone” for  3D alignment of the foot prior to a TAR procedure could be instrumental in preventing  osteolysis, a condition that can eventually lead to implant failure.

The study was carried out at institutions using CurveBeam weight bearing  imaging solutions,  which provided the researchers with automatic 3D  measurement tools such as TALAS. The authors explained this research contributes to the comprehension of how peri-prosthetic cysts develop in the ankle.

The award recipients were Francois Lintz, MD, FEBOT; Jef Mast, MD; Mazim Medhi, MD; Alessio Bernasconi, MD; Cesar de Cesar Netto, MD, PhD; and Kristian Buedts, MD.

Press Release: CurveBeam Announces New Validated Protocols for LineUP™ Weight Bearing CT Imaging System

LineUP System Now Compatible with Wright Medical’s PROPHECY™ Preoperative Navigation System and Portfolio of Total Ankle Replacement Implants

HATFIELD, PENN. — Sept. 10, 2019 – CurveBeam, a leader in extremity CT imaging, announced it has developed and validated protocols for the LineUP weight bearing CT imaging system that are compatible with Wright Medical Group’s PROPHECY™ Preoperative Navigation System and portfolio of total ankle replacement implants. Hospitals and orthopedic practices selected to participate in a controlled release will be able to submit LineUP scans to be used in PROPHECY’s virtual preoperative alignment process to create patient-specific surgical guides, with the potential for the protocol to be available to all LineUP users.

CurveBeam will showcase examples of how weight bearing computed tomography (WBCT) scans produced on the LineUP were utilized in Wright’s proprietary technology to model patients’ unique anatomy to determine implant component sizes and alignment at the American Orthopaedic Foot & Ankle Society (AOFAS) Annual Meeting in Chicago from September 12 – 15, 2019.

Dr. Robert Santrock, an orthopedic surgeon at the West Virginia University Health System, will deliver a lecture at CurveBeam’s exhibit (#932) on Friday, September 13 to discuss how he used the LineUP composite knee-foot scan protocol with the PROPHECY system for his patients who are undergoing a total ankle arthroplasty procedure.

“WVU elected to place the LineUP in the Orthopedic Department, which makes scheduling and performing scans for patients more convenient,” Dr. Santrock said. “I am delighted I am now able to use LineUP technology in conjunction with the PROPHECY Preoperative Navigation System.”

“The application of WBCT imaging to patient-specific surgical modeling holds tremendous potential to enhance the accuracy of preoperative plans and assessment of post-operative results. It has a tremendous potential to improve outcomes,” said Arun Singh, President & CEO of CurveBeam.

The Wright Medical PROPHECY system is used with Wright’s INFINITY™ and INBONE™ Total Ankle Replacement Systems and its INVISION™ Total Ankle Revision System.

The CurveBeam LineUP is a weight bearing Extremity CT imaging system. Its innovative design allows for a patient to be scanned while he/she is standing naturally on both feet. The AOFAS recommends weight bearing imaging when possible to get the most accurate assessment. The LineUP offers the largest field-of-view in its class, which allows for both distal limbs to be captured in a single scan.

The LineUP is compact, self-shielded and plugs into a standard wall outlet, making it ideal for point-of-care orthopedic settings. A study published in the International Journal of Diagnostic Imaging concluded, “[due to extremely low levels] radiation should not be a concern when considering the use of WBCT imaging for foot & ankle examination.” For more information about CurveBeam’s extremity CT imaging solutions, visit www.curvebeam.com.
