A medical appliance adapted to bridge and stabilize spaced apart bone segments having outside, ledge and inside surfaces. The appliance has an elongate bottom plate, an elongate top plate, and a locking member. The bottom plate is attachable to the ledge surface of the bone and has a bottom base plate, a plurality of screw barrels extending from the bottom base plate in a first direction for receiving barrel screws, and a plurality of openings in the base plate for rotatably retaining the screw barrels. The elongate top plate has a top plate base, a plurality of slots aligned to allow the barrel screws to engage the screw barrels of the bottom plate. The locking member is dispoaed in a countersink to engage the bone screws such that axial and rotational movement of the bone screws may be restricted. The screw barrels are equipped with an angle first end and a riveted second end to restrain screw movement but allow the screws to engage the barrels at various angles. A locking member includes a locking ring having a plurality of tapered rachet teeth on an interior surface.

A middle expanded, removable disk implant for stabilizing adjacent vertebrae. The implant is substantially rectangular in cross-sectional shape with a minimal height and a width greater than the height. The implant is detachably mounted to an applicator for insertion into the anatomical region between two adjacent vertebrae from which a portion of the intervertebral disk has been removed, and once inserted, is positioned by anterior-posterior movement in the disk space to the position in which both the expanded, larger width middle portion and the smaller diameter end portions of the implant will engage the bodies of the adjacent vertebrae and the implant is then rotated to bring the sides of the rectangularly-shaped implant defining the width of the implant, with its larger dimension, into engagement with the bodies of the adjacent vertebrae. A lock is then secured to the implant to prevent further rotation thereof.

A method of stabilizing adjacent vertebrae is disclosed using a middle-expanded, removable disk implant. The implant is substantially rectangular in cross-sectional shape with a minimal height and a width greater than the height. The implant is detachably mounted to an applicator for insertion into the anatomical region between two adjacent vertebrae from which a portion of the intervertebral disk has been removed, and once inserted, is positioned by anterior-posterior movement in the disk space to the position in which both the expanded, larger width middle portion and the smaller diameter end portions of the implant engage the bodies of the adjacent vertebrae and the implant is then rotated to bring the sides of the rectangularly-shaped implant defining the width of the implant, with its larger dimension, into engagement with the bodies of the adjacent vertebrae. A lock is then secured to the implant to prevent further rotation thereof.

A rotating, locking, spring-loaded disk implant for stabilizing adjacent vertebrae. The implant is substantially rectangular in cross-sectional shape with minimal height and maximal width. The implant is inserted into the space between two adjacent vertebrae from which a portion of the intervertebral disk has been removed and, when positioned in the disk space, rotated to bring the sides of the rectangularly-shaped implant defining the width of the implant, with its larger dimension, into engagement with the bodies of the adjacent vertebrae. A portion of the implant is biased away from the implant and into contact with the adjacent vertebrae to provide a cushioning effect between the implant and the vertebra. A lock is then secured to the implant to resist further rotation of the implant in the disk space.
