Computer Navigation Total Hip Arthroplasty – The Hip “Xpert”
Aug 30, 2019Richard “Alex” Sweet II, MD
What is navigation and robotic surgery?
A computer is used to improve implant positioning compared to traditional methods in an attempt to reduce complications. Robots and computers offer levels of precision and accuracy far beyond the natural capabilities of any surgeon. Recently, there has been an increasing trend towards incorpo-rating robots and computers in surgery. There are many options available for patients and surgeons.
How important is the position of the components?
This is the most crucial aspect of the surgery that determines long term results. Certain “safe zones” of implant positioning lead to fewer dislocations, improved implant longevity and overall better outcomes. Although surgeons know where the components need to be positioned, some studies have found that up to 50% of traditional hip replacements fall outside of these safe zones. Advancements in surgical techniques and technologies, including the anterior approach and Hip Xpert navigation, have led to improved implant positioning.
What is the downside to traditional computer navigation and robotic surgery?
As with any robot or computer generated system, success is dependent on the human-technology interface. When the “human element” is introduced into the system, there is an inherent weakness and potential for mistakes. Additionally many of the robotic and navigation systems increase the time that the patient is under anesthesia and that the wound is open. The #1 key to avoiding complications is performing an efficient surgery to get the patient out of the surgical suite before an infection or medical complication occurs.
What makes the Hip Xpert a better option for me?
The Hip Xpert has many advantages over other systems. The biggest advantage is that the entire surgical plan can be known before the surgery even begins. A virtual surgery is performed well in
advance of the day of surgery. I am able to visualize your exact anatomy and customize for your needs. It’s like having a road map for the perfect surgery that is tailor made to each patient’s unique anatomy. This allows for a streamlined surgical procedure to minimize complications and helps to ensure a better outcome.
How does the system work?
The first step is to get a CT scan, which is a highly accurate 3D scan of the bones of the hip and pelvis. Your unique anatomy can be visualized much more accurately this way. The CT scan is sent to the Hip Xpert company. They create a 3D model of your hip joint which is then sent to me. I then perform the virtual surgery, building you a hip that perfectly fits with your bony and soft tissue anatomy. Finally, once in surgery I will have access to the 3D model and the entire navigated plan. If needed, intraoperative adjustments to the surgical plan can be made instantly, allowing a streamlined procedure with excellent outcomes.
Is the Hip Xpert really better?
If I didn’t believe this was a superior product, I would not offer it to my patients. I firmly believe in the outcomes of this patient-specific and personalized navigation tool, and highly recommend it. Beyond my own personal beliefs, the reliability and accuracy of the Hip Xpert has been scientifically validated in major orthopedic journals. When compared to some of the most commonly used navigation systems, it was found to be significantly more accurate. Unlike conventional navigation, the Hip Xpert completely eliminated component positioning outside the safe zones. This results in a much improved surgical technique that minimizes complications and maximizes outcomes.
What does it cost me to use the Hip Xpert?
Because this technology is privately owned, it falls outside the realm of health insurance companies.There is a total cost of $1,500 to have this personalized navigation plan created for you. The goal of hip replacement surgery is to give you a new, pain free, and well functioning hip that lasts ideally for the rest of your life. While there are no guarantees in any surgery, this is my goal as your surgeon. Investing in the Hip Xpert is an investment in your wellness and future, giving you the best opportunity for an excellent outcome.
Is navigation necessary and/or worth it?
Total hip replacements have been around long before any sort of computer navigation technology. However, as technology advances, so too does our surgical technique. Utilizing the newest technology is always something that we in the healthcare industry strive to do. I feel that I can offer two great options for patients. The first is an anterior approach with the use of the Hip Xpert. The second is an anterior approach without this technology, but still utilizing cutting edge X-ray technology and a complex surgical anatomic understanding to give my patients the best possible
outcome. However, I believe that the Hip Xpert makes me a more precise and accurate surgeon. With this technology I can perform your surgery more safely and efficiently, and better match the
implants to your exact anatomy. This will give you the highest possible chance of a great outcome.
