Abstract: An insertion instrument for inserting a modular Oblique Lumbar Interbody Fusion (OLIF) device into an intervertebral space. The insertion instrument comprises a hand grippable support and first and second elongate arms extending therefrom along a longitudinal axis. Each of the first and second arms is configured at its distal end to grip a respective one of a superior plate and an inferior plate of the modular OLIF device. The distal ends oppose each other whereby, in use, an inferior surface of the superior plate and a superior surface of the inferior plate face each other. The proximal ends of the first and second arms are mounted on the hand grippable support for relative rotation of the first and second arms about the longitudinal axis. The proximal ends of the first arm and second arms have respectively a first and second, third and fourth sides facing away from each other and spaced apart in a direction orthogonal to the longitudinal axis and to a direction of separation of the first and second arms.

Abstract: An intervertebral fusion device 10 is disclosed. The intervertebral fusion device 10 comprises at least one endplate 40, 70 and a core component 20. The at least one endplate 40, 70 is configured to be received in an intervertebral space between first and second vertebrae. Each at least one endplate 40, 70 comprises first and second endplate parts which are coupled to each other to allow the first and second endplate parts to move apart to thereby increase a perimeter of the endplate. The core component 20 is configured to inter-engage with each at least one endplate 40, 70. The core component 20 is unitary. As the core component 20 is progressively brought into inter-engagement with the at least one endplate 40, 70, the core component bears against the first and second endplate parts to push the first and second endplate parts progressively apart.
