摘要： A guide and method of using the guide for positioning within a patient between vertebral members for contouring each of the members. The guide comprises a first section (20) and a second section (30). A first edge (22) is positioned along an edge of the first section, and a second edge (32) is positioned along an edge of the second section. One or more elongated rods (42) extend through the sections. One or both of the sections are movable along the rods to adjust a spacing between the first edge and the second edge. When positioned within the patient, the first edge is aligned along a first vertebral member (210) and the second edge is aligned along a second vertebral member (220). A manner of locking the sections is included for preventing the sections from moving relative to each other once the first and second edges are aligned within the patient.

摘要： A modular intervertebral prosthesis system includes first and second baseplates (20) and an insert (70) designed to mate to the baseplates (20). The baseplates (20) include a mounting section (30) and a intervertebral section (50) extending away from the mounting section (30) generally perpendicular thereto. The intervertebral section (50) has at least one aperture (60) passing therethrough. When installed, the insert (70) is disposed between the intervertebral sections (50) of the baseplates (20) and faces the apertures (60). In this way, the insert (70) is not insulated from the vertebral members, thereby allowing for osteoinduction, osteoconduction, and/or osteointegration, if desired. The insert (70) may take the form of an articulating-type insert or a fusion-type insert, with the baseplates being operative with both types of inserts. After installation of the insert (70) between the baseplates (20), the insert (70) may be readily removed, at least initially.

摘要： Spinal spacers (20) are provided for fusion of a motion segment. The spacers include a load bearing member (21) having a wall (22) sized for engagement within a space between adjacent vertebrae to maintain the space and an effective amount of an osteogenic composition (30) to stimulate osteoinduction. The osteogenic composition includes a substantially pure osteogenic factor in a pharmaceutically acceptable carrier. In one embodiment the load bearing member includes a bone graft impregnated in an osteogenic composition. In another embodiment, the osteogenic composition (30) is packed within a chamber (25) defined in the graft. Any suitable configuration of a bone graft is contemplated, including bone dowels, D-shaped spacers and cortical rings.

摘要： Systems and methods for measuring a separation characteristic of separated anatomical elements include a separator contactable with first (12) and second (14) anatomical elements. A sensor (18) provides an indication of the separation characteristic of the anatomical elements. The measured separation characteristic can be compared with a desired or predetermined separation characteristic, and subsequent surgical procedures can be performed based on the measured separation characteristic

摘要： One embodiment of a spinal spacer (10) includes an anterior wall (11) having a convexly curved anterior surface and opposite ends (12, 13), a posterior wall (15) having opposite ends (16, 17), two lateral walls (20, 21), each integrally connected between the opposite ends (12, 13, 16, 17) of the anterior (11) and posterior (15) walls to define a chamber (30). The walls (11, 15, 20, 21) include a superior face (35) and an inferior face (38), each defining friction or vertebral engaging surfaces. In one specific embodiment, a solid D-shaped spacer (40) is provided. In another specific embodiment, the spacer (10, 40) is composed of a biocompatible bone ingrowth material that has a sufficient surface roughness to provide a friction fit. In a still another embodiment, the bone ingrowth material includes a plurality of continuous interconnected pores that contain a bone morphogenic protein to facilitate bone ingrowth into the spacer.
