    摘要： Intervertebral spacer implants with dynamic load spreading features responsive to external loads and having attachment mechanisms. The dynamic load spreading features having a native state and a loaded state, which complements vertebral end plate geometry and disperses load to the epiphyseal rim.

    摘要： An intervertebral implant for spondylolisthesis correction includes a superior side with serrations angled superiorly and toward the implant insertion direction, an inferior side with serrations angled inferiorly and opposite the implant insertion direction, and an instrument connection feature. An instrument for connection to the implant includes an implant connection feature movable between unlocked and locked states, and a friction-reducing feature movable between disengaged and engaged states. The instrument has a first state, in which the implant connection feature is in the unlocked state and the friction-reducing feature is in the disengaged state; a second state, in which the implant connection feature is in the locked state and the friction-reducing feature is in the engaged state; and a third state, in which the implant connection feature is in the locked state and the friction-reducing feature is in the disengaged state. Methods of apparatus assembly and surgery are disclosed.

    摘要： Intervertebral implant systems include spacers that may have solid and porous bodies integrally formed together as a single part. The bone-facing sides of the spacers include asymmetric lobes which may include solid and/or porous portions. Bone anchor holes may extend through the spacers and lobes, to receive bone anchors. A helically fluted bone anchor may be received in the bone anchor holes.
