TRINITY MOTHER FRANCES CENTER FOR ADVANCED SURGERY AND TECHNOLOGY ADDS KNEE AND HIP REPLACEMENT NAVIGATION SYSTEM
Surgical System acts as a Global Positioning System to Better Align Implant with Patient's Anatomy
TYLER, TX - Officials with Trinity Mother Frances Health System announced that Mother Frances Hospital is the first in the region to install a state-of-the-art surgical navigation system from Stryker. The Hospital is among the first in the area to use a computer-assisted navigation system in conjunction with orthopedic joint replacement surgery.
"Image guided navigation technology for orthopedic surgery is designed to allow a surgeon to align an artificial joint with greater precision within the body," said Chris Glenney, vice president of operations, Mother Frances Hospital. "Precise alignment is an important factor that may reduce joint wear and extend the life of the implant. Use of the system has many potential benefits including improved joint stability and range of motion."
Orthopedic navigation technology is similar to directional tracking systems used in cars and ships - it is, in effect, a global positioning system (GPS) for the surgeon. Infrared sensors placed in the operating room act like satellites constantly monitoring the location of markers and instruments placed along a patient's anatomy.
As the surgeon moves an instrument within a patient's joint, the infrared sensors calculate its position and smart wireless instruments instantaneously transfer the data to a computer in the operating room. This information is then displayed as an interactive model of the anatomy or "blueprint" that supplies the surgeon with the optimum angles, lines and measurements needed to align the implant within the patient.
Mother Frances Hospital is currently using this navigation technology in knee and hip replacement surgeries. Many surgeons are using this technology in less invasive techniques that help reduce the size of the incision and disrupt less soft tissue. Computer-assisted surgery provides the surgeon with a clearer view.
According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) about 500,000 hip and knee replacement procedures are performed annually in the United States. This figure is expected to increase as the population ages and arthritis affects more people. Currently, more than 70 million Americans suffer from some form of this degenerative disease.
Trinity Mother Frances Health System includes Mother Frances Hospital-Tyler, Mother Frances Hospital-Jacksonville, and Trinity Clinic. Trinity Clinic is a multispecialty physician group with over 200 providers representing 35 specialties serving east, northeast and north-central Texas.
