Tech Talk: Meet the O-Arm
Lexington Medical Center is the first hospital in the Midlands with the technologically advanced O-Arm, a new imaging system for spinal surgery.
The O-Arm is a machine placed around a patient on the operating table. Before surgery, doctors use the O-Arm to capture images of the patient that help them develop a precise surgical guide. During surgery, the O-Arm images allow neurosurgeons to confirm proper placement of instrumentation. After implants are placed, neurosurgeons use the O-Arm again to confirm correct placement of instruments in the spine and address anything further that needs to be done. Images are displayed on a large, digital flat screen at a view station next to the operating table.
For an up-close look at the O-Arm in the Lexington Medical Center operating room, watch this video. Dr. Scott Boyd, neurogurgeon at Columbia Neurology Associates narrates.
Before O-Arm technology, patients would have an MRI or CT scan before surgery and doctors would use 1- or 2-Dimensional images to guide them. They would place instruments and implants by using their best educated guess based on standard anatomy. But in back surgery, doctors are working through a small opening and it can be difficult to know where you are in the spine. Margins of error are millimeters – and implants must be placed with a great deal of accuracy.
Manufactured by Medtronic, the O-Arm improves safety for surgeons and staff members, lowers the chance of revision surgeries and can enhance patient outcomes. Spinal problems can be chronic and debilitating. The O-Arm gives patients a great opportunity for excellent results.
Lexington Medical Center began using the O-Arm this summer. For more information, visit www.lexmed.com/O-arm
