Computer-Assistance Technology in Joint Replacement Surgery at Lakeland
Surgical navigation system enhances
patient outcomes and longevity of the prosthesis.
Kenneth J. Edwards, MD,
orthopedic surgeon, and his partners are improving outcomes for total-hip
replacement patients with the help of new computer-assisted technology in the
operating room at Lakeland Hospital, St. Joseph. Surgeons can dramatically
improve alignment and see more clearly the unique anatomy of each individual
patient. Using electronic imaging, surgeons can accurately track, during
surgery, where the instruments are relative to the patient’s anatomy and make
adjustments to ensure the best possible fit.
"Using the navigation system allows us to have
a greater level of confidence in the accuracy of placement," said Dr. Edwards,
"especially in the current age of minimally invasive joint replacement surgery."
Computer-assisted joint replacement surgery
combines computers, infrared cameras and wireless instruments for a continual
flow of data related to joint mechanics and the placement of surgical
instruments and implants. The data is based on measurements of the individual
patient’s anatomy, which means the surgeon does not have to rely on pre-surgical
CT images or standard instrumentation based on average anatomical shapes and

• Guidance to make accurate surgical cuts
within a fraction of a degree
• Real-time cup positioning
• Evaluation of
the functional performance of the components
• Accurate implant positioning
• Patient data and results
Computer-assisted surgery is
applicable to all patients who are candidates for total-hip replacement and can
be used with any hip prosthesis regardless of manufacturer.
"I have been very pleased with
the enhanced accuracy achieved with this system," stated Dr. Edwards. "Having
the hip components in an ideal position improves leg length, equality and
component placement. Maximizing joint placement enhances patient outcomes and
longevity of the prosthesis."
"At Lakeland, we feel an
obligation to invest in new technologies, which assist our physicians and staff
in providing high-quality care for our patients," said Lowell Hamel, MD,
vice president, medical affairs, Lakeland Regional Health System.
