Effect of cyclical loading on the holding power of surgical screws

Although clinical failure of bone screws commonly involve pullout after repetitive lateral loading this mode of failure has rarely been reported previously. The authors examined the effect of cyclical shear force on the fixation stability and holding power of bone screws. The mechanical influence of...

Zusammenfassung:Although clinical failure of bone screws commonly involve pullout after repetitive lateral loading this mode of failure has rarely been reported previously. The authors examined the effect of cyclical shear force on the fixation stability and holding power of bone screws. The mechanical influence of design variables on the fatigue stability and pullout strength was studied. Different screw designs had significantly (p
