Abstract:
1. An interbody implant system comprising: an implant including a body have a distal end portion and a proximal end portion and a first articulation surface formed at a proximal end of said proximal end portion; and an insertion instrument including an elongate shaft having a proximal end portion and a distal end portion; a second articulation surface formed at a distal end of said distal end portion, said second articulation surface configured to interface with said first articulation surface; and an attachment member configured to connect said implant to said insertion instrument; said body of said implant having an elongate opening formed in said proximal end portion, said elongate opening having a first height dimension and a first width dimension, wherein said first height dimension and said first width dimension are not equal; said attachment member having a distal attachment portion having a second height dimension and a second width dimension, said second height dimension being unequal to said second width dimension in a plane normal to a longitudinal axis of said attachment member, wherein said second height dimension is less than said first height dimension and said second width dimension is less than said first width dimension, but said second width dimension is greater than said first height dimension; wherein said attachment member is actuatable to rotate about a longitudinal axis of said elongate shaft, relative to said elongate shaft, and to compress the first and second articulation surfaces together in a locked configuration with sufficient force to prevent relative rotation between said first and second articulation surfaces, and said attachment member is actuatable to reduce an amount of compression force existing in said locked configuration to place the first and second articulation surfaces in an unlocked configuration such that said first articulation surface can rotate relative to said second articulation surface.
