A spinal implant includes a hollow body having a distal end, a proximal end, and a pair of lateral walls extending from the distal end to the proximal end, the lateral walls having a concave-shaped cross-section and having concave, non-threaded interior surfaces for defining an at least partially cylindrical internal space between the lateral walls. The hollow body has upper and lower faces that are inclined relative to one another, whereby a distance between the upper and lower faces decreases from a first lateral side of the hollow body to a second lateral side of the hollow body opposite the first lateral side. The implant includes an anchoring member having bone anchoring projections that is inserted into the hollow body. The anchoring member is rotatable for enabling the anchoring member to be screwed into the internal space of the hollow body.

Intersomatic implants

A spinal implant includes a hollow body having a pair of lateral braches extending from a leading end to a trailing end of the hollow body. The branches have opposing concave, non-threaded inner surfaces defining an internal space of the hollow body and outer surfaces defining an outer dimension of the hollow body. The hollow body has upper and lower faces extending between leading and trailing ends thereof. At least one of the lateral branches has a first opening extending between the outer and inner surfaces thereof, and a second opening located outside the internal space of the hollow body and extending between the upper and lower faces, the first and second openings being in communication with one another. The implant also includes an anchoring member insertible between the lateral branches and into the internal space of the hollow body, whereby the concave inner surfaces of the lateral branches substantially conform to the outer diameter of the anchoring member.

Two part intersomatic implant

A method of stabilizing bone, such as a spine, includes providing a coupling element having first and second sections that are angled relative to one another, the coupling element having rod receiving openings for securing an elongated member such as an orthopedic rod, and assembling the coupling element with an anchoring element. The method includes securing the anchoring element in bone, moving the coupling element relative to the anchoring element to align the rod receiving openings with the orthopedic rod, securing the orthopedic rod in the rod receiving openings, and after the securing step, locking the coupling element from further movement relative to the anchoring element.

Methods for stabilizing bone using spinal fixation devices

A spinal implant comprising a hollow body having a leading end, a trailing end and a pair of lateral walls extending from the leading end to the trailing end, the lateral walls including concave, non-threaded inner surfaces defining an internal space of the hollow body. The implant includes an anchoring member insertible between the lateral walls and into the internal space of the hollow body, the anchoring member having bone anchoring projections defining an outer diameter of the anchoring member. When the anchoring member is inserted into the internal space of the hollow body, the concave inner surfaces of the lateral walls substantially conform to the outer diameter of the anchoring member.

A screw fastener for attachment to an orthopedic component such as an orthopedic plate for use in connection with fracture fixation, joint reconstruction or spinal stabilization or fusion is disclosed as having a shank with at least two different shank diameters, one in a plate engaging portion of the shank and one in the bone or other component engaging portion of the shank. At least two of the different shank diameters on the shank include threads, the threads on the two different diameter portions each having substantially the same thread height and pitch. A plate having a threaded aperture, or an adapter having a threaded aperture, is sized such that the threads of the smaller diameter shank portion engage and cooperate with the internal threads of the aperture to correctly align the screw fastener and the implant as the screw fastener is threaded through the implant. The threads on the larger diameter shank portion and the internal threads of the aperture of the implant are sized so that the threads of the larger diameter shank portion are fully engaged with the internal threads of the orthopedic implant.

Self-guiding threaded fastener

Bone plating implants, instruments, systems and methods for fracture fixation are provided. The systems includes the instruments and implants comprising a trial component, handle, aiming block, bone plate, tissue spreader, drill guide, K-wire guide, monoaxial screw-locking inserts, polyaxial screw-locking inserts, cable plugs, K-wires, monoaxial screws and polyaxial screws. The methods include the use of the instruments and implants for either open or minimally invasive fracture fixation surgery.

Bone plating implants, instruments and methods

A corpectomy device has an inner member telescopingly disposed in an outer member so that the inner member is movable in an axial direction. The inner and outer members are hollow, defining a chamber, and include apertures in communication with the chamber. A locking clip engages the inner and outer members to fix the position of the inner member with respect to the outer member. The longitudinal dimension of the device is adjustable by distracting the inner member so that the inner member extends from the outer member and moving the locking clip from an unlocked position to a locked position.

Telescoping spinal implant

A spinal implant includes a hollow body having a distal end, a proximal end, and a pair of lateral walls extending from the distal end to the proximal end, the lateral walls having concave, non-threaded interior surfaces for defining an at least partially cylindrical internal space between the lateral walls. The spinal implant also includes an anchoring member having bone anchoring projections including a screw thread on an exterior surface thereof, wherein at least one of the lateral walls adjacent the proximal end of the hollow body includes a reentrant thread adapted to cooperate with the screw thread of the anchoring member when the anchoring element is rotated for enabling the anchoring member to be screwed into the internal space of the hollow body. The anchoring member has a proximal end, a distal end, a major axis extending between the proximal and distal ends, an interior space, and a fork surrounding the interior space, the fork including branches extending along a major axis of the anchoring member, the branches having a frustoconical exterior surface with a diameter that decreases from the proximal end toward the distal end of the anchoring member, and wherein the screw thread comprises a helical band connected to the fork and encircling the fork and the interior space of the anchoring member.

Two-part intersomatic implant

The invention concerns an implant ( ) for replacing a vertebra at least-partially, consisting of two parts ( ) adapted to be mutually connected while enabling the adjustment of the implant total dimension (L), each part having an invariable dimension (m, f) homologous with the implant total dimension (L). The parts ( ) form a screw-nut connection with each other.

Implant for replacing a vertebra

The intersomatic spine implant comprises a body, at least one anchoring element movable relative to the body to project from a contact face of the body making contact with a vertebra, and at least one cam slidable relative to the body and suitable for displacing the anchoring element relative to the body by the effect of a ramp engaging the anchoring element. The cam and the anchoring element are arranged so that the cam moves the anchoring element in two opposite displacement directions.

Intersomatic spine implant having anchoring elements

An implant device designed for replacing a vertebral body of the spine. The implant device contains at least one moving member so as to vary the distance between a first and second member. Most preferably this movement is achieved by rotating at least one cam about an axis. The cam or cams are shaped so as to comprise an irregular polygon thus allowing the height of the implant device to be varied at discrete positions. A slidable telescopic engagement device within the implant device affords the added advantage of simple adjustment and maneuverability.
