3D Tech Allows NY Orthopedic Surgeons Better Control Over Surgical Tools
Northern Westchester Hospital’s Orthopedic and Spine Institute provides orthopedic surgery patients with increased comfort and improved outcomes using custom-built surgical tools made from 3D modeling techniques.
Using new 3D modeling technology, our orthopedic surgeons are now able to simulate knee replacement surgery on a patient and custom-order surgical instruments to better assist during surgery.
By uploading a patient’s magnetic resonance images, or MRIs, to a computer program, orthopedic surgeons can use 3D modeling techniques to create a 3D illustration of the knee. Surgeons are then able to simulate placement of the implants weeks ahead of the actual surgery date. Using simulation, the surgeon can take into account the unique aspects of each patient’s case. He or she then sends an approved pre-operative plan to the surgical tool manufacturer. The manufacturer uses the plan to design and create pin placement guides to meet the patient’s exact specifications.
Director of Quality and Outcomes at the Orthopedic and Spine Institute at Northern Westchester Hospital, Dr. David Yasgur
, is excited about the opportunities the new technology offers.
“You have tremendous control in fitting the implant to meet each patient’s unique needs—how much cartilage is left in the joint, for example, or how a previous trauma like a fracture will alter wear and tear,” he said. “Essentially, all the decision-making and fitting that would happen during surgery can be done on a computer four to six weeks ahead of time.”
Using 3D modeling techniques for knee replacement has the potential to make surgery much less painful for patients. The patient also spends less time on the operating table – about 15 to 20 minutes less – which has its own benefits, including a lower risk of infections, bleeding, and other complications during surgery. The patient’s recovery time is faster as well.
“During surgery, we needed to have a large variety of instruments out and available for making adjustments to the size and alignment of the implants—all while the patient was undergoing the procedure. This wasted time and placed additional stress on the patients,” said Dr. Yasgur, who has a background in healthcare technology development. Before medical school, he helped design and develop prostheses for total joint replacement surgery.
