Table I.

Initial stiffness, number of cycles, and maximum load to failure for three groups: sliding hip screw with anti-rotation screw; locking plate system with spring-loaded telescoping screws; and three cannulated screws in an inverted triangle configuration.

Group	Mean initial stiffness, N/mm (SD)	Mean cycles to failure, n (SD)	Mean load at failure, N (SD)
SHS	535 (172)	65,974 (33,670)	1,790 (674)
LP	805 (414)	66,933 (43,726)	1,815 (873)
CS	625 (351)	43,775 (36,289)	1,355 (720)

CS, three cannulated screws in an inverted triangle configuration; LP, locking plate system with spring-loaded telescoping screws; SHS, sliding hip screw with anti-rotation screw.
