1st Cases Using hipEOS 3.0, Intellijoint Smart Nav Combo Announced

Paris, France-based EOS imaging has announced the first patient cases performed with its hipEOS 3.0 surgical planning software delivered intraoperatively by Intellijoint HIP, a navigation system, which offers surgeon-controlled surgical guidance for intraoperative positional measurements during total hip arthroplasty (THA).

Peter K. Sculco, M.D., an orthopedic surgeon at Hospital for Special Surgery (HSS) in New York City, performed the first cases. In his view, “I did four total hip replacement my first day using the combined hipEOS preoperative planning software combined with Intellijoint Hip surgical platform. Overall, the cases went smoothly because the operative plan was clearly outlined and presented along with my intraoperative numbers. I think the hipEOS planning software allows for more comprehensive preoperative planning than plain radiographs. I understand each patients’ dynamic pelvic motion in standing and sitting positions in additional to their native femoral version which allows me to calculate combined seated anteversion and decide whether I should use a regular femoral head, neutral liner, lipped liner and the optimal position of the elevation, or convert to a dual mobility. I feel more confident in the OR knowing that I have a deeper understanding of the patients’ anatomy, lumbo-sacral kinematics, and can better predict components best suited for each patient to minimize complications. Secondarily, hipEOS allows me to differentiate between intra-articular and extra-articular leg discrepancies and also better assess primary versus secondary pelvic obliquities which may allow for more accurate overall leg length restoration when taking this into consideration at time of THA.”

hipEOS 3.0 incorporates weight-bearing (standing and sitting) EOS images with 2D/3D patient specific models and datasets. Using hipEOS 3.0 plan intraoperatively by Intellijoint HIP, says EOS, “enables surgeons to select the best implant type and size, its ideal position and orientation as well as to make real-time intraoperative measurements that deliver an accurately executed plan in the operating room.”

The system is powered by EOSlink™, for seamless integration of its EOSapps. According to EOS’s marketing literature, “these offerings ensure the optimized clinical results, while reducing leg length discrepancies and risk of dislocation or impingement.”

“We are excited to showcase the robustness of Intellijoint HIP through its ability to accept and deliver preoperative surgical plans for THA,” said Armen Bakirtzian, CEO and co-founder of Intellijoint Surgical. “This first case at HSS demonstrates the benefits of hipEOS preoperative planning and the value Intellijoint HIP brings in accurately delivering patient specific plans in the operating room.”

Asked how hipEOS optimizes range of motion based on each patient’s 3D anatomy, EOS imaging CEO Mike Lobinsky told OTW, “hipEOS enables the surgeon to perform a range of motion assessment in a patient’s functional standing and sitting positions. It also provides the ability to detect implant-on-implant impingement. With this information, the surgeon can optimize the implant type and orientation in order to minimize the risk of impingement and potential dislocations.”
