Abstract: A rod, screw, rod receiving member, and staple assembly for use in conjunction with anterior or lateral spinal rod implant apparatus includes a vertebral body screw, staple, and rod receiving member which are initially loosely coupled together such that they may each rotate about a common axis. They are held together by virtue of the head of the screw being held within a tapered axial bore of the rod receiving member and the staple being loosely mounted around the rod receiving member. The lower portion of the rod coupling member is expandable by virtue of a series of slots formed in its lower portion. The screw seats within the axial bore of the rod receiving member such that a rod inserted in the channel of the member seats on the head of the screw. With the rod coupling element and staple combination mounted to the screw, it is driven into the vertebral bone. The member is then rotated into position to receive the rod, which seats on the head of the screw. The application of a top locking nut causes the rod to compress against the head of the screw which translates downwardly in the bore, thus expanding the lower portion of the member, and locking the staple and the screw to the member.

Abstract: The present invention is an acetabular cup having at least one polyaxial locking screw for anchoring the cup in the desired bone site. The assembly includes an acetabular cup having at least one through hole having both threaded and tapered portions, into which holes a two-piece interlocking coupling element and a bone screw having a semi-spherical head may be inserted. The two-piece coupling element, including slideably joined socket and cap portions, is mounted about the semi-spherical head of the bone screw, which is inserted into the through hole and into the bone. The head of the screw is polyaxially mounted in the socket portions and as such may be inserted into the bone at a variety of angles. The socket portion of the coupling element has slots which permits crush locking of the head of the screw once the socket seats and is forceably driven into the tapered portion of the hole. The cap portion is threaded so is may be advanced into the inner portion of the hole, thereby further locking the coupling element into the hole, and applying an additional driving force against the socket portion to crush lock the screw head at the selected angle relative to the cup.

Abstract: A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate head, a two-piece interlocking coupling element which mounts about the curvate head, and a rod receiving cylindrical body member having a tapered socket into which both the screw and the interlocking coupling element are securely nested. The interlocking coupling element includes a socket portion which is slotted and tapered so that when it is radially compressed by being driven downwardly into the tapered socket in the cylindrical body it crush locks to the screw. The securing of the rod in the body member provides the necessary downward force onto the socket portion through a contact force on the top of the cap portion. Prior to the rod being inserted, therefore, the screw head remains polyaxially free with respect to the coupling element and the body. In a preferred embodiment, the cap portion and the socket portion are formed and coupled in such a way that when the cap portion is compressed toward the socket portion, there is an additional inward radial force applied by the cap portion to the socket portion, thereby enhancing the total locking force onto the head of the screw.

Abstract: A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate ball top, a polyaxial head member having a socket into which the head of the screw is initially polyaxially nested, a vertical slot which renders the socket compressible, and a horizontal through hole having a tapered portion on one side of the vertical slot. A rod gripping cross-bar member, which is mounted through the through hole includes an axial split which permits the first end thereof to grip a rod, and then to be clamped onto the rod when the axial slot is narrowed. A nut is provided on the end of the cross-bar member which extend out from the through hole on the opposite end from the rod gripping mechanism. The advancement of the nut causes the cross-bar member to be compressed by the taper of the front portion of the through hole, thereby locking the rod in the gripping end thereof, and further provides the compression force necessary to compression lock the interior socket of the head against the ball top of the screw.

Abstract: A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate head, a cross bar mounting element having a socket into which the head of the screw is initially polyaxially nested. The cross bar mounting element further includes a vertical split which permits the socket to be expanded or compressed via the application of a corresponding force directed at the split. The cross bar mounting element further includes a pair of upwardly extending members which define a trough into which a cross bar element is positioned. The cross bar element includes features which permit the secure fixation of a rod thereto, as well as a selectively slideable element, such as a nut, which may be tightened to apply the compressive force necessary to compress the interior volume onto the head of the screw, thus locking the assembly in place.

Abstract: A polyaxial orthopedic device for use with rod implant apparatus includes a hook or a screw having a recess which includes a lower portion and an upper portion, the up per portion is curvate. A rod receiving head having a channel formed therein, and a central bore which is curvately tapered at the inside bottom, and equivalently curvately tapered on the exterior surface, is polyaxially seated in the upper portion of the recess while a post element is inserted down through the head into the lower portion of the recess. The upper portion of the post is widened and curvate so that it seats in the curved lower interior of the bore of the head. The insertion of a rod into the head, onto the top of the post and the subsequent application of a downward force thereon by a nut causes the assembly to lock together, independent of the polyaxial angle of the head to the post and hook, or screw. The post may be held in the recess by means of a transverse dowel positioned in a co-linear transverse hole formed in the recess or post or by sweat locking the post into the recess; the process of sweat locking meaning the insertion of the post into the recess when there is a relative temperature differential being maintained between the two elements such that the post can be inserted into the hole, and the subsequent expansion of the post and contraction of the recess sweat locks the two elements together.

Abstract: A hook and rod apparatus for implantation and fixation to the centerline of the spine, wherein the rod provides for immobilization of the spine via its inherent rigidity. The hook elements are designed to be mounted at the arched portion of the lamina. In a first plow shaped variation, the blade portion of the hook is an arched surface which seats under the arched surface of the lamina. In a second claw shaped variation, the blade portion includes a bifurcated conformation having a pair of offset flat extending members which are offset so as to seat under the angled portions of the lamina which are directly laterally disposed relative to the arched center of the lamina. The rod coupling features of the hooks may further be polyaxial by virtue of separate coupling elements which may be mounted to the blade portion, for example on a semi-spherical head portion thereof. In the alternative, the blade portion may have a contractible recess formed in a top thereof, for receiving and locking to a shaft of body portion at a variety of heights. The rod receiving features of the hook may include both the polyaxial and height variability natures of both of the previous hooks by having a shaft portion which has a semi-spherical head onto which the coupling element is mounted.

Abstract: A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate head, a bicentric locking shell disposed therearound, and a coupling element having a curvate tapered socket into which both the screw and the shell nest. The bicentric shell is slotted and has a semi-spherical interior volume into which the screw head is initially polyaxially held. The coupling element has an axial bore through which the screw and shell may be inserted, and a curvate bottom having a smaller radius of curvature than the shell, which provides a radially inward force on the locking shell when forced thereinto. This radially inward force causes the shell to crush lock against the head of the screw, therein locking the two at the instant angulation. In an initial disposition, however, the screw and the shell head remain polyaxially free with respect to each other, and to the coupling element. The coupling element also includes a transverse channel in which a rod may be disposed. In a first embodiment the channel is formed between a pair of upwardly extending members, and in a second embodiment, the channel is formed in the side of the element. In either case, a rod which is inserted in the channel seats against the top of the shell and the head of the screw. Engagement of a locking nut on the top of the coupling element provides a downward force against the rod, and forces the locking shell into the socket in the bottom of the bore, thereby locking the rod, locking shell, and screw simultaneously.
