In one embodiment, a cutting guide is disclosed for use in a surgical procedure to removed damaged tissue from a patient and form a recipient site configured and dimensioned to receive a donor graft. The cutting guide includes a first arm that abuts a section of the damaged tissue to be removed, and a second arm including a hole and a slot that receives a cutting implement, the first arm and the slot defining a distance therebetween corresponding to a desired dimension of the recipient site. In another embodiment, a cutting guide is disclosed for use in forming a donor graft from donor tissue. The cutting guide includes a body that receives the donor tissue, and a shaping member that is rotatably secured to the body. The shaping member includes at least one vane that shapes the donor tissue so as to form the donor graft.

Device and method for allografting

Systems, apparatus, and methods may be adapted for grafting tissue at a tissue site that may include an elongate housing and a plurality of elongate cutting members. The plurality of elongate cutting members may define a cutting surface at a distal end of the elongate housing. The cutting surface may be adapted to contract from a first diameter to a second diameter that is less than the first diameter. The contraction of the cutting surface from the first diameter to the second diameter may define a tapered profile between the first diameter and the second diameter suitable for obtaining a tapered graft.

System, apparatus, and method for grafting tissue

A fusion cage of the present invention includes a first housing portion, a second housing portion, and an insert portion adapted to be received therebetween, wherein the geometry of the fusion cage corresponds substantially to the geometry of a void into which the fusion cage is to be inserted. Also described is a novel tool for insertion of a fusion cage and a novel method for designing a fusion cage or other surgical implant for filling a void identified within a patient.
