Surgeons from the Weill Cornell Center for Brain and Spine Neurosurgery, New York Presbyterian Hospital, have developed a new single-step pedicle screw system for minimally invasive spinal surgery.
Their related research "New MIS 3D NAV Single-Step Pedicle Screw System (SSPSS): Workflow, Accuracy, and Initial Clinical Experience" was published in the January 12, 2021 edition of the "Global Spine Journal".
In a prospective case series, the researchers evaluated patients who used this system for pedicle screw fixation between October 2017 and April 2018. Ruptures are classified into grade 1 (<2 mm), grade 2 (2-4 mm), or grade 3 (<4 mm), and are classified as head, tail, medial, and lateral.
Results: 135 screws and 24 patients later discovered that their single-step pedicle screw system was a very promising alternative to guide wires, Jamshidi needles, and other instruments, helping to minimize pedicle screw breakage risks of.
Co-author Roger Härtl, MD, is Professor of Neurosurgery and Director of Spine Surgery and Neurotrauma at the Weill Cornell Brain and Spine Center in New York, and director of the Weill Cornell Center for Comprehensive Spine Care Medicine. "The world of MISS technology is constantly evolving," Dr. Härtl told OTW. This is a single-step system, which means it does not require guide wires, Jamshidi needles, and pedicle preparation tools. "
Make "minimally invasive" smaller
"It is interesting to realize that this is definitely a safe technology," Dr. Härtl commented on OTW. "And, of course, efficient because it is a single-step percutaneous pedicle screw system. Our spine surgeons have improved minimally invasive spine surgery with a new screw system, which reduces the steps of inserting vertebral screws from five steps To one — improve the accuracy of screw placement, reduce operation time, and restore the pathological range of spinal stability in patients with scoliosis."
"This means saving time. This leads to shorter operation times. The surgeons of the NewYork-Presbyterian Och Spine program are advancing the field with minimal access technology, 3D navigation technology, and innovative instruments to improve all age groups suffering from various spine The life of the patient in question."
