Abstract: An anterior cervical plate system with integrated locks which is additively manufactured as one component is disclosed. The anterior cervical plate system comprises a plate having at least one through hole configured to receive a bone screw for attaching the plate to a patient's bone. The plate includes a lock component adjacent to the at least one through hole. The lock component is connected to the plate such that the lock component is permitted to rotate with respect to the plate. The lock component has an unlocked position in which the locking ends of the lock component do not cover the head of the bone screw inside the through hole, and a locked position in which at least part of the locking ends engage the head portion of the bone screw to prevent the bone screw from backing out of the through hole.

Abstract: An improved bone screw device having an internal lattice structure for bone integration and to promote bony ingrowth. The improved bone screw device has a cylindrical body with a first end and a second end and a cutting flute. The head of the bone screw is configured to engage with a driver to advance the screw into a patient's bone, and a distal tip is positioned at the second end. The cylindrical body further includes an internal lattice structure formed at a base of the cylindrical body, near the distal tip. Further, an exterior thread is formed on the cylindrical body and helically surrounds the internal lattice structure. In use, bone is channeled into the internal lattice structure, which helps to fixate the distal tip of the bone screw into the patient's pedicle, bone or joint.

Abstract: A medical device such as an interbody cage component, a hip stem component, or an acetabular shell component having a microstructure in at least one direction for osteointegration and boney in-growth. The microstructure is controlled by machine parameters and may be created by an additive manufacturing program. Typically, the microstructure occurs in both the +/?X and the +/?Y directions, and the microstructure can be added in the range of 0.010 to 0.150 mm.

Abstract: An improved bone screw or medical device comprising at least one smooth surface and at least one textured surface. The improved bone screw has a cylindrical body with a first end and a dosed second end. The head is positioned at the first end and configured to engage with a driver to advance the bone screw into a bane, and a tip is positioned at die second end. The exterior thread of the screw component has a smooth surface and a textured surface on at least one side and, preferably, only one side. The textured surface promotes honey on-growth and mechanical interlocking, and prevents premature withdrav,u1 of the bone screw from the bone. The smooth surface reduces the amount of insertion torque required during the installation process.

Abstract: A surgical screw system and device with a screw head having multiple insertion engagement features. The screw preferably a tubular body having a first end and a closed second end, wherein the head configured to engage with a diiver to advance the screw into the bone. The head of the screw has at least two different insertion features, such as a cross shaped insertion feature and a hexalobe shaped insertion. The screw can be advanced or removed via a driver that mates with the cross shaped or the hexalobe shaped insertion features.

Abstract: A structurally encoded implant comprising a pair of endplates movably secured at the posterior end via a slip joint and a wedge component. The wedge component is inserted between the pair of endplates to increase implant height and change the lordotic angle. The pair of endplates may be manufactured together as one integral component using additive manufacturing techniques. During this additive manufacturing process, water-soluble support material may be positioned around the slip joint. Once the pair of endplates is formed, the support material may be dissolved away, allowing the pair of endplates to move independently from one another, but to still remain movably attached via the slip joint, such that the pair of endplates allow for height expansion and lordotic angle change.

Abstract: An implantable interbody negative pressure device that permits reduced or negative pressure therapies to be applied to a portion of a patient's body. More specifically, the implantable interbody negative pressure device comprises a body portion having a plurality of openings in fluid communication with both an internal passageway and a vacuum source, and that serves as a manifold and permits reduced or negative pressure therapy to be applied to a surgical site, such as a wound or damaged bone. The application of the reduced or negative pressure to the body improves circulation and the disposal of cellular waste, and promotes bone growth and healing.

Abstract: The present teachings are directed to a shoulder prosthesis having an adjustable radial offset and/or angular inclination provided by relative rotation of an adapter interdisposed between a stem and a head. In one example, a prosthesis has a stem having a first longitudinal axis. The prosthesis can also include an adaptor including a first taper. The first taper can have a first taper axis. The prosthesis can include a head supported by the adaptor. The head can be selectively oriented and then coupled to the first taper and the combination can be selectively orientated and the coupled to the stem.

Abstract: A anti-splay and rod securing member for use with vertebral implants of the hook, monoaxial and polyaxial types, in which a pair of arcuate upstanding internally threaded posts define a transverse opening for securing a rod to immobilize bone segments comprises an integrally formed cap and set screw with the cap having opposed curved side walls extending around the posts and flat end walls, the set screw being positioned within the posts and free to rotate within the cap so that rotation of the set screw will advance the cap and set screw in unison along the implant posts to clamp the rod and implant together. The implant may be provided with opposed catch basins for releasably securing the distal end of a rod persuasion instrument.

Abstract: A transverse connector system for interconnecting two spinal rods includes a connector arranged to span the distance between the rods with a rod receiving recess and a pin receiving bore on each end. A one-piece pin member such as a set screw is disposed within each bore with an enlarged head protruding from the bottom of the connector so that when the set screw is retracted into the bore the head engages a side of the respective rod to clamp the rod within the recess. The connector may comprise two elongated members with a recess and pin receiving bore at one end of each member, a middle coupler which allows three degrees of freedom between the members to accommodate any anticipated spatial orientation between the members and a set screw for securing the other ends of the members together.

Abstract: The present invention is directed to a modular shoulder prosthesis having an adjustable radial offset and/or angular inclination provided by relative rotation of an adapter interdisposed between the stem and the head. Specifically, the interface configuration between the stem and the adapter, as well as between the adapter and the head are designed such that relative positioning of these components provides a continuous adjustment in the radial offset and/or angular inclination. Indicia are provided at the interface between the adapter and the head to precisely determine the magnitude and direction of the adjustment being made.

Abstract: A transverse connector system for interconnecting two spinal rods includes a connector arranged to span the distance between the rods with a rod receiving recess and a pin receiving bore on each end. A pin member such as a set screw is deposited within each bore with an enlarged head protruding from the bottom of the connector so that when the set screw is retracted into the bore the head engages a side of the respective rod to clamp the rod within the recess. The connector may comprise two elongated members with a recess and pin receiving bore at one end of each member, a middle coupler which allows three degrees of freedom between the members to accommodate any anticipated spatial orientation between the members and a set screw for securing the other ends of the members together.
