An interbody spacer assembly includes a pair of end pieces spaced apart by a connector extending between them. The end pieces extend generally parallel to the end plates of adjoining vertebral bodies. Fasteners connect the end pieces to the vertebral bodies. Bone graft material or solid bone can be placed in the interior space defined by the end pieces and connector, which bone graft material or solid bone eventually fuses together and to the adjoining end plates through the end pieces.

Cervical interbody device

A modular bone fastener system for use with a longitudinal member, such as a plate, having a fastener with a threaded lower potion for engaging a spinal element and an upper portion adapted to receive a headpiece. The headpiece is adapted to mate with the upper portion of the fastener and to engage a longitudinal member. A plurality of headpieces having angulated projections, lateral sections, and angulated lateral sections, all of which are adapted to engage a longitudinal member and overcome angular and translational misalignment of the fastener, may also be provided. The headpieces of some connectors are configured to permit angulation of a bore fastener relative to the connector.

Modular spinal system

A modular pedicle screw system for use with a longitudinal member, such as a plate or rod, having a fastener with a threaded lower portion for engaging a spinal element and an upper portion adapted to receive a headpiece. The headpiece is adapted to mate with the upper portion of the fastener and to engage a longitudinal member. A plurality of headpieces having angulated projections, lateral sections, and angulated lateral sections, all of which are adapted to engage a longitudinal member and overcome angular and translational malalignment of the fastener, may also be provided.
