Abstract:
:Between July 1983 and November 1986, 29 patients with thoracolumbar burst fractures underwent a one-stage operation consisting of anterior decompression by subtotal vertebrectomy, reduction, and stabilization with the Slot-Zielke device. The mean follow-up was 3.1 years. Most patients with incomplete neurologic lesions showed postoperative improvement and were upgraded one or two steps in the Frankel scale. No patient showed neurologic deterioration after surgery. In all patients, bony union occurred. Loss of reduction of more than 5 degrees occurred in 41% of the patients. Because of this high rate of loss of reduction in patients and the low degree of flexion-bending loading and torsional stability in biomechanical evaluation in vitro of the Slot-Zielke device on human cadaveric spines, an additional posterior stabilization of the spine after an anterior approach for anterior- and middle-column fractures should be considered.

SPINE文献大全abstract::Giovanni Alfonso Borelli is often described as the father of biomechanics. He was born in Naples in 1608. His De Motu Animalium, published in 1680, extended to biology the rigorous analytical methods developed by Galileo in the field of mechanics. Borelli calculated the forces required for equilibrium in various joint...
