In a prospective clinical trial, researchers from Germany confirmed the use of percutaneous posterior thoracolumbar pedicle screws using two-plane fluoroscopy as an effective method for treating spinal fractures.
“This study demonstrates the feasibility of placing percutaneous posterior thoracolumbar pedicle screws with the assistance of conventional fluoroscopy,” the researchers wrote in their study abstract. “Minimally invasive transpedicular instrumentation is an accurate, reliable and safe method to treat a variety of spinal disorders, including thoracic and lumbar spine fractures.”
The researchers analyzed 502 percutaneous screws inserted using conventional fluoroscopy in 111 patients, according to the abstract. Screw placement safety and accuracy were evaluated by CT scans. Postoperatively, the researchers found 427 screws (85%) were of good or excellent length and 494 screws (98%) had good or excellent positioning, according to the abstract.
