Cypress Fairbanks Medical Center Hospital announced that it now offers advanced image-guided surgery for orthopedic procedures of the hip and knee. Image-guided surgery, also known as computer-assisted surgery, allows your operating physician to make the slightest adjustments during the procedure that may help improve the results of your surgery.

“These procedures are designed to help your surgeon place the joint replacement implants with precision,” explains David Navid, DO, board certified, fellowship trained orthopedic surgeon on the medical staff at Cy-Fair Hospital. “A poorly positioned replacement can lead to early loosening, increased wear, and poor function, so the better the positioning, the more usable life you will receive from the replacement.” Other benefits include:

  • Reducing the risk of dislocation following hip replacement
  • Resulting in greater stability and range of motion of the hip
  • Restoration of function and decreased pain of the knee

“Computer-assisted surgery also allows for less-invasive surgical techniques in some cases,” adds Dr. Navid. “Minimally invasive procedures also have advantages, including reduced blood loss during surgery.”

The technology uses special tracking devices providing your surgeon with a comprehensive understanding of your joint mechanics in the operating room (OR). “Armed with this information, adjustments can be made within a fraction of a degree, helping to ensure improved overall function of your new joint,” says Dr. Navid.

As the surgeon moves an instrument within a patient’s joint, special infrared trackers calculate its position and wireless instruments transfer the data to a computer in the OR. “The information we receive from this technology helps provide us with an interactive model of your anatomy, including measurements and angles of your unique physiology,” adds Dr. Navid.
