Baptist Health Louisville adds Computer-Assisted Technology for hip replacement surgery

The latest advancement in orthopedic surgery helps more accurately align and orient the hip implant with the patient’s specific anatomy.

Baptist Health Louisville announced that it has installed a state-of-the-art surgical navigation system from Stryker. Baptist Louisville is among the first in the state to use computer-assisted technology in conjunction with total hip replacement surgery.

Computer-assisted surgery is designed to allow a surgeon to accurately position an artificial joint with greater precision within the hip. Precise placement is an important factor that may reduce joint wear, and extend the life of the implant.

The computer analyzes and displays data on a computer monitor in the form of graphs that supply the surgeon with the angles, lines, and measurements needed to accurately position the prosthesis. With it, there is the opportunity to give a patient a new hip that has improved joint stability and increased range of motion.

As the surgeon moves an instrument within a patient’s hip joint, special infrared trackers calculate its position and smart wireless instruments instantaneously transfer the data to a computer in the OR. This information is then displayed as an interactive model of the anatomy or “blueprint” that provides the surgeon with a comprehensive understanding of the patient’s unique anatomy. Benefits of computer-assisted joint replacement include shorter hospital stays, fewer post-operative complications, and improved joint stability. 

Many surgeons are using it in less invasive techniques that help reduce the size of the incision and disrupt less soft tissue. Minimally invasive surgery has additional patient benefits including shorter hospital stay, quicker rehab and a smaller scar.

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.
