EXPANDABLE INTER-BODY DEVICE, SYSTEM, AND METHOD
Expandable spinal implants, systems and methods are disclosed. An expandable spinal implant may include a first endplate, a second endplate, and a moving mechanism that is operably coupled to the first and second endplates. The moving mechanism may include a wedge, a first sliding frame and a second sliding frame disposed on opposite sides of the wedge, a screw guide housing a rotatable first set screw and a rotatable second set screw opposite the first set screw. The first set screw may be operably coupled to the second sliding frame and the second set screw may be operably coupled to the wedge. The moving mechanism may operably adjust a spacing between the first and second endplates upon simultaneous rotation of the first and second set screws and operably adjust an angle of inclination between the first and second endplates upon translating the first set screw or second set screw.
Intervertebral support
An intervertebral support device to impose an anatomic distance between two adjacent vertebral bodies having a pair of vertebral support elements for introduction between the edge portions of the rear half of the vertebrae, at respective substantially symmetrical positions of the instantaneous rotation axis of the natural relative flexion-extension movement of the two adjacent vertebrae. The device assists stabilizing and/or restoring the correct position of the rotation axis, which characterizes the first stage of the degenerative breakdown, without significantly limiting the relative movement of the two vertebrae. The support elements have preferably a constraint means that constrains them to the edge portions of the vertebral bodies, in particular to resist the reaction force on the intervertebral disc.
Bio-mechanically compatible 3D-printed intervertebral disc
An artificial replacement disk assembly comprised of a core in between two endplates. The endplates have outer surfaces that match the surface morphologies of the corresponding vertebral endplates. The endplates may have textured inner surface to form a strong fusion with the core during the fabrication process. The thick solid endplates strongly fused to the core create a very resilient implant. Gripping structures on the endplates may permit easy manipulation of the assembly during surgical procedures.
INTERSPINOUS INTEGRATION TYPE IMPLANT
The present invention relates to an interspinous integration type implant. Provided is an interspinous integration type implant which is an implant inserted between an upper spinous process and a lower spinous process and comprises: a spacer to which one end of an upper plate and one end of a lower plate are connected so as to be formed in a “” shape or “U” shape, and which is inserted between spinous processes in order to provide elasticity; an upper spinous process coupling means for tightly coupling the upper plate to the upper spinous process; and a lower spinous process coupling means for tightly coupling the lower plate to the lower spinous process, wherein the upper plate comprises at least one osseointegration hole formed to penetrate the top surface and the bottom surface of the upper plate so as to be moved by being integrated with the upper spinous process, and the lower plate comprises at least one osseointegration hole formed to penetrate the top surface and the bottom surface of the lower plate so as to be moved by being integrated with the lower spinous process. The interspinous integration type implant according to the present invention provides elasticity to the upper spinous process and the lower spinous process, thereby maintaining a space between the upper and lower spinous processes. Also, the interspinous integration type implant moves by being integrated with the upper and lower spinous processes through the osseointegration holes formed at the upper plate and the lower plate, and thus does not damage the spinous processes and has an effect of preventing a separation phenomenon from between the spinous processes. Also, the interspinous integration type implant has an effect of enabling minimally invasive surgery since blades can be rotated and tightened using an instrument after inserting the interspinous integration type implant from the side surface of spinous processes. Furthermore, after inserting the interspinous integration type implant between adjacent spinous processes and tightening the blades at both side surfaces of the spinous processes, a plurality of spikes provided in the blades are tightly embedded on the both side surfaces of the spinous processes, and thus there is an effect that an upper blade and a lower blade are stably coupled to the upper and lower spinous processes. In addition, since the interspinous integration type implant can be inserted between the spinous processes in a state where the upper blade an
OPTIMIZED CAGE SYSTEMS PROMOTING BONE REPAIR AND FUSION
This invention provides, inter alia, a device having a cage having an opening or window in at least one of its walls that allows for the insertion of bone growth promoting materials therethrough, comprising one or more openings in one or more of the walls of the cage, designed to receive bone growth promoting materials, including coral-based materials, which facilitate in the fusion with the treated bone, and which optionally serves to reinforce the stability of the implanted structure. Methods of stabilizing two skeletal structures relative to one another, joining two skeletal structures which are discontinuous and repairing a ligament tear or replacing a ligament making use of a bone fusion device of the invention are described.
LATERAL SPINE PLATE WITH LATERAL SPINE CAGE ANCHORING SYSTEM
A spine stabilization and fusion system includes a lateral cage having a lateral cage bore hole. The system also includes a lateral cage insertion shaft comprising a leading end, a mid-portion, and a terminal end. A shape of the leading end matches a shape of the lateral cage bore hole such that the leading end mates with the lateral cage bore hole via a friction fit. The system also includes a lateral plate having a lateral plate bore hole and a plurality of holes, where the lateral plate bore hole receives the mid-portion of the lateral cage insertion shaft, and where the plurality of holes receive fasteners to couple the lateral plate to one or more vertebra.
Intersomatic cage, intervertebral prosthesis, anchoring device and implantation instruments
An intersomatic cage, an intervertebral prosthesis, an anchoring device and an instrument for implantation of the cage or the prosthesis and the anchoring device are provided. An intersomatic cage or an intervertebral prosthesis fit closely to the anchoring device, which includes a body of elongated shape on a longitudinal axis, of curved shape describing, along the longitudinal axis, an arc whose dimensions and radius of curvature are designed in such a manner that the anchoring device may be implanted in the vertebral plate of a vertebra by presenting its longitudinal axis substantially along the plane of the intervertebral space, where the anchoring device is inserted, by means of the instrument, through a slot located in at least one peripheral wall of the cage or on at least one plate of the intervertebral disc prosthesis to penetrate into at least one vertebral plate.
Shapeable porous metal implant
Shapeable porous metal implants and methods for use in various procedures are disclosed. The implants can comprise a shell according to some examples. According to one example, the method can include providing a sheet of highly porous metal material having a porosity of between 55% and 90%, and wrapping the sheet of highly porous metal material around at least a first bone of the patient. Further examples can form the sheet intra-operatively to a desired shape. In an example, the porous metal sheet can be formed of tantalum or tantalum alloys.
