ULTRA-PRECISE ROBOTIC HIP SURGERY BREAKS GROUND
First-Ever Anterior Hip Replacement with MAKO® Rio®Robot Scheduled in Illinois
HINSDALE, IL. — It sounds like the stuff of science fiction, but it’s really American ingenuity at its best. The first hip replacement surgery in the United States performed with the newer direct anterior approach and using a brand new device called MAKOsurgical® Rio® Robotic Arm Interactive Orthopedic system, was performed on September 5, 2012 at Hinsdale Hospital in Hinsdale, Illinois. The surgeon, Dr. Michael Durkin of Hinsdale Orthopaedics, is one of fewer than a dozen surgeons worldwide certified to perform the procedure. The surgery is said to be vastly more precise in aligning the implanted device to achieve a better “fit” for the patient.
The direct anterior approach to hip replacement begins with an incision from the front side of the body, rather than the more conventional back side. Along with a commonly used device called a hana® table, the direct anterior approach is considered by many specialists to provide superior results in terms of recovery time, mobility, post-operative pain, positioning of the leg and risk of post-operative dislocation. According to Dr. Durkin, when the MAKOsurgical® Rio® robot is added to this mix, there are even more benefits.
“The implanted device is basically a ball and socket,” says Dr. Durkin, “and a key part of the surgeon’s job is positioning the socket, or the acetabulum, exactly where it will provide the most natural fit for the femural head, or the ball, which is attached to the leg.” Dr. Durkin commented that there is a certain acceptable range of positioning for this, which is commonly referred to by orthopaedists as “the box.”
“It’s necessary to be ‘in the box,’” Dr. Durkin comments, “in order to consider the operation a success and to achieve the best long-term results for the patient.” However, a recent study of more than 6,000 hip replacements performed at Massachusets General by some of the best orthopaedic surgeons in the country found that they are within the acceptable parameters for positioning the implant – in other words, they are ‘in the box’ – only about 37 percent of the time. When adding the robotic assistance, the percentage rises to over 99 percent.
“It’s a remarkable tool,” Dr. Durkin indicates. “Whereas we have conventionally relied upon x-rays, CT scans and our experience to position the implant, we are still unable to achieve 50 percent accuracy without the MAKOsurgical® Rio®robot. With it, we triple our ability to be ‘in the box.’ It’s a device that can make the surgeon much better, instantly.”
The procedure begins with pre-operative CAT scans, which are then run through a MAKOsurgical® computer for a process called “segmenting,” or identifying the measurements to “landmarks” on the patient’s body. These measurements are reviewed by the doctor and a surgical plan for the implant is approved. The numbers are then imported into the robotic arm, which is controlled by the doctor during surgery. And end-of-surgery computations further confirm the success of the measurements, providing instant verification for the success of the implant positioning.
Like many orthopaedic surgeons, Dr. Durkin was originally trained on the posterior hip replacement procedure, which approaches the joint from the back of the body. He has performed many hundreds of these surgeries through his affiliations with Hinsdale, Good Samaritan, and Elmhurst Memorial hospitals, and dozens of the newer direct anterior surgeries over the last 18 months, as well. But the robotic arm adds a technological twist. Dr. Durkin underscores that the robot does nothing without his control, however.
“The MAKOsurgical® Rio® robot lets the surgeon make minor alignment adjustments with nearly perfect precision during surgery, providing real-time feedback during this process. Combining the MAKOsurgical® Rio® robot with a hana® table on a direct anterior approach, in my opinion, blends three very good technologies to achieve exceptional results.”
The Robot-assisted MAKOsurgical® Hip Replacement procedure, which is only about a year old, was developed by MAKOsurgical® based in Fort Lauderdale, Florida. Founded in 2004, the company has been making headlines ever since with its robotic devices designed to enhance the results of orthopaedic surgeries such as total knee replacements, in addition to hip replacement. The MAKOsurgical® hip procedure takes about the same amount of time as hip replacements done without it, although it saves the patient a substantial amount of radiation during the operation, since x-rays are not required to the extent that they are when the robotic arm is not used. And once a patient has been qualified for hip replacement, there is virtually nothing that would disqualify that patient from being a candidate for a procedure that utilizes the MAKOsurgical® device. What’s more, there is no added cost. While it is too soon for insurance companies to reimburse the doctors who use it, Hinsdale Orthopaedic currently does not charge a fee for use of the robot. Meaning all of the benefits come at no added cost to the patient.
Although Dr. Durkin, who has a degree in bioengineering, in addition to his University of Illinois medical degree, is one of only two surgeons currently certified to perform this procedure in Illinois and one of only 10 nationally, he fully expects those numbers to go up quickly.
“I think people will see that this technology gives them a more precise option for getting their joint replacement done with better comfort, function and longevity,” he says. “As surgeons, we are always looking for ways to achieve better results for our patients. I feel this technology lets us achieve the best possible outcome in hip replacement.”
