摘要： An interbody spacer system for insertion between a first vertebra and a second vertebra according to the principles of the present disclosure includes and interbody spacer and a first curved blade. The interbody spacer includes an outer wall and a first surface for engaging an endplate of the first vertebra and a second surface for engaging an endplate of the second vertebra. A first entry aperture in the outer wall and a first exit aperture on the first surface communicate with a first curved path extending therebetween. The first curved blade enters the first entry aperture and exits through the first exit aperture to secure the spacer to the first vertebra.

摘要： An interbody spacer system for insertion between a first vertebra and a second vertebra according to the principles of the present disclosure include an interbody spacer (102) including an anterior wall (106), a posterior wall (112), and a pair of sidewalls (108, 110) connecting the anterior wall (106) and the posterior wall (112) to form a cavity (114) having open top and bottom, the anterior wall (106) including a first entry aperture (124a), a first sidewall (108) of the pair of sidewalls (108, 110) including a first exit aperture (128a) proximate to the anterior wall (106); a first helical path (122a) extending from the first entry aperture (124a) to the first exit aperture (128a) through a portion of the anterior wall (106) and through a portion of the first sidewall (108); and a first helical blade (104a) configured to enter the first entry aperture (124a) and exit the first exit aperture (128a) through the first helical path (122a), and extend in a first helical direction across the top of the cavity to a second sidewall (110) of the pair of sidewalls (108, 110) proximate to the posterior wall (112).
