Closely-held Intellijoint Surgical plans to improve patients’ lives by providing every orthopaedic surgeon with their surgical 3D solution that provides real-time intraoperative measurements to ensure accurate size selection and positioning of artificial implants during total hip arthroplasty (THA), which involves replacement of the damaged portion of the hip with artificial components.
“The sky’s the limit for our core technology developed in anticipation of multiple products tailored to specific workflows, but our first focus has been on our flagship product, intellijoint HIP, custom built for hip surgery,” Armen Bakirtzian, co-founder and CEO, says in an interview with BioTuesdays.
Traditionally, orthopaedic surgeons are equipped with preoperative images of the patient’s hip to help them plan what they would like to achieve in the THA. Important targets, such as leg length, offset, or the distance of the leg from the midline of the body, and even orientation of the implantable cup, are set preoperatively.
“The downside is that these preoperative images are only useful in helping to create a preoperative plan, not execute it,” Mr. Bakirtzian contends. “As a result, up to 62% of cups are not placed within a predetermined target range, and up to 49% of all unassisted THA result in leg length discrepancy of more than 5 mm.”
According to Mr. Bakirtzian, with intellijoint HIP, a miniaturized, surgeon-controlled, 3D optical navigation camera and tracker, surgeons are provided with real-time, intraoperative measurements to assist in proper sizing and placement of the implant. With these quantitative measurements, “the device then helps align the implant in the desired location without having to rely on pre-operative imaging so cup position, leg length, offset, and hip centre of rotation are accurately determined,” he adds.
With regulatory approval in U.S., Australia, Europe and Canada, intellijoint HIP is indicated for anterior, posterior and lateral approaches in both primary and revision THA, he says.
“In only eight years we’ve moved from a small start-up to a fully commercialized scale up with over 5,000 THA cases completed in top orthopaedic hospitals throughout the world,” Mr. Bakirtzian explains. “Our plan in the near future is to expand our core technology into other areas such as knee arthroplasty.”
The Intellijoint Surgical core technology uses a combination of hardware and software and integrates miniature optical sensors with tailored software packages to offer seamless integration into any standard surgical workflow and is compatible with every major implant vendor, he adds.
“Our device takes the guesswork out,” Mr. Bakirtzian points out. “Surgeons no longer have to eyeball hip implant positioning, minimizing risks that can include joint instability resulting in dislocation, leg length discrepancy, and revision surgery later.”
As the story goes, intellijoint HIP is the result of a conversation between Mr. Bakirtzian and his orthopaedic surgeon father who voiced frustration with current navigation systems that violated key criteria important to orthopedic surgeons such as speed, ease of use, and integration with workflow.
“It was originally a final year university design project,” Mr. Bakirtzian says, who then pitched the intellijoint HIP idea at the 2010 Next Top Young Entrepreneur Start-Up Pitch Competition, along with colleagues Richard Fanson and Andre Hladio. “After winning the competition we co-founded Intellijoint Surgical and began the journey to commercialize our flagship product.”
Currently, there are 1.2 million THA procedures performed in Canada, U.S. and EU annually. Hip replacement surgery generally leads to positive results. However, dissatisfaction occurs in between 15% and 30% of patients, with the most common complaint being that legs are different lengths.
“With other computer assisted navigation systems, between 1.5% and 3% of THA require revision surgery with readmissions usually within 90 days of primary surgery,” Mr. Bakirtzian says.
“There are other image-based navigation technologies out there, but they are not suitable for revision THA,” Mr. Bakirtzian says. “The other systems rely on pre-operative imaging, but that can result in significant inaccuracies because the image can be distorted by metal from existing components placed during primary surgery.”
“Up to 8.9% of patients will be readmitted within 90 days with most readmissions due to instability and dislocations,” he adds.
“Our sophisticated, yet simple smart tool is the only 3D mini-optical navigation solution cleared for both primary and revision THA,” Mr. Bakirtzian says. “It can reduce the risk of revisions because it provides accurate information down to the millimeter, so surgeons can make the right decisions for each individual patient, intraoperatively.”
Using the intellijoint HIP device only adds approximately three minutes to the surgery time, he explains.
“We’ve been able to address the shortcomings of traditional navigation with a solution that has a short learning curve, and that offers hospitals a low risk, no up-front investment, pay as you go model that provides the patient with the very best possible outcome in orthopaedic surgery,” he adds.
