Abstract:
Objective The purpose was to compare the biomechanical characteristics of new percutaneous guide wire and conventional wire in cadaveric spines,and to evaluate the new percutaneous guide wire's efficacy and safety in a clinical trial.Methods Compared the push-out and penetration forces of the new percutaneous guide wire and conventional wire in fresh cadaveric lumbar spines from L1 to L5.And analyzed the related complications of new percutaneous guide wire by clinical experiment.Results Push-out forces caused the spiral part of the new percutaneous guide wire to bend or spread,so as to resist the anterior migration of the guide wire.The mean push-out forces of the new percutaneous guide wire and conventional wire were (15.5-+ 1.9) N and (5.7 ± 0.8) N respectively (P ＜ 0.01),and the mean penetration forces were (69.1 ±4.2) N and (37.1 ±4.8) N respectively (P ＜0.01).There was no wire breakage or anterior-wall penetration in the clinical trial of 222 new percutaneous guide wire.Conclusion The mean push-out and penetration forces of the new percutaneous guide wire were approximately 2 to 3 times greater than those of conventional wire.The new percutaneous guide wire effectively prevented guide-wire anterior migration and penetration of the anterior vertebral-body wall.The new percutaneous guide wire device could effectively improve the safety of percutaneous pedicle screw insertion procedures for patient with osteoporosis.
