1. A system comprising an intervertebral implant and a device to insert the intervertebral implant into a body, the intervertebral implant comprising a top surface, a bottom surface, and a side wall extending between the top surface and the bottom surface, the intervertebral implant defining an internal hollow space with at least a portion having a spherical segment shape and that is accessible through an opening extending through a first portion of the side wall, wherein the first portion of the side wall has at least a curved portion and a planar portion, wherein the device comprises:
a drive shaft having a longitudinal axis and comprising an engagement portion configured to engage the hollow space of the intervertebral implant; and
a sleeve positioned around at least part of the drive shaft and movable along the longitudinal axis relative to the drive shaft, the sleeve comprising a distal end face having at least a curved portion and a planar portion;
wherein when the engagement portion of the drive shaft is in the hollow space, the intervertebral implant is configured to be held at a first position relative to the device where the curved portion of the distal end face engages the curved portion of the side wall of the intervertebral implant while the planar portion of the distal end face is spaced apart from the side wall, and to be held at a second position relative to the device where the planar portion of the distal end face engages the planar portion of the side wall while the curved portion of the distal end face is spaced apart from the side wall.
