Disclosed is a delivery system for an intervertebral spacer and a bone grafting material in the form of a unitary device which comprises a spacer disengagingly attached to a hollow handle. The handle comprises a chamber and bone grafting material-advancing means within the chamber for introducing the bone grafting material from the chamber into and around the spacer and the intervertebral spaces. The handle is disengageable from the spacer after serving its purpose of facilitating placement of the spacer and the discharge of the bone grafting material into the spacer and the intervertebral space.The intervertebral spacer implant portion is attached to the handle portion at the exit port of the chamber, the point of attachment constituting the entry port of the intervertebral spacer implant portion.The spacer has voids therein capable of receiving the bone grafting material from the chamber, and the chamber, the spacer implant portion voids, and the intervertebral spaces are in flow communication with each other whereby bone graft material expressed from the chamber is capable of entering the intervertebral spacer implant voids and the intervertebral spaces.
