A system and methods for a safe and efficient distributing of bone graft material into an intervertebral disc space are provided. Systems are provided for receiving, removing, and replacing of preloaded load cartridges in a rapid and repeating manner. The systems can also be designed for rapidly delivering the biologics from a single load cartridge and, to even further facilitate a rapid and repeating delivery of biologics, the load cartridge and cartridge tamp can be adapted so that the cartridge tamp can capture and remove the load cartridge after delivery of fusion promoting material in the load cartridge.

A prosthetic implant replaces hyaline cartilage in a synovial joint with a flexible polymer sliding surface, preferably of hydrogel, on a segmented support with an array of adjacent segments to which the hydrogel is molded. Adjacent segments are laterally and angularly displaceable permitting the implant to conform to rounded or irregular surfaces or to be rolled or folded for arthroscopic placement. Tension cables threaded through segments along a circuit can cinch segments together for stiffening the supporting layer and/or the cable can pull the implant against a bone surface. Adjacent segments can have inter-engaged structures. In some embodiments the segments are carried on a flexible foil or fibrous sheet.

An implant may include a body having a first portion and a second portion and a structural member having a central member curve. In addition, the structural member may be exposed on an outer surface of the implant. Further, the central member curve may include a winding segment, and the winding segment of the central member curve may wind around a fixed path extending from the first portion of the body to the second portion of the body. Also, the central member curve may make one or more full turns around the fixed path. And, the structural member may have a member diameter at the winding segment, wherein the winding segment has a winding diameter corresponding with the full turn around the fixed path and the member diameter is greater than the winding diameter.

The invention relates to an arthrodesis plate for the stiffening of joints, in particular finger joints, comprising a proximal and distal anchoring region which are connected to one another in a mechanically rigid manner, characterised in that at least one outer contour of one of the two anchoring regions has a cross-section which is undulating, for example roof-shaped, or is provided with alternating crests and troughs by means of coating, and/or has a transversal-sagittal cross-section.

Technologies are generally provided for devices, systems, and methods to provide spinal fixation, spinal stabilization, and/or spinal fusion. Example devices may include a first end and a second end with a middle portion extending between the first and second end. The first end may be configured to be in contact with a portion of a first or upper vertebra and the second end may be configured to be in contact with a portion of a second or lower vertebra in an adjacent vertebral pair. Portions of the vertebra which may be in contact with the device may include lamina, processes, vertebral bodies, and facet joints. The example devices may include bone engagement features, such as screws or similar fasteners, to enhance stabilization and fixation when in contact with the vertebrae. Additionally, the devices may include a bone integration feature to promote bone growth and to facilitate fusion between the vertebrae.

A sacroiliac fusion stabilizer (SIFS) for fusing a first bone fracture fragment to a second bone fracture fragment is provided. In one embodiment, the SIFS has a lazy-S shape with a series of protrusions at the ends of the SIFS. In another embodiment, the SIFS has two overlapping lazy-S shapes.

An interbody spine implant has a PEEK body/cage and removable front, the body with bone screw holes of a diameter smaller than a greatest diameter of an associated bone screw such that received bone screws cut into the PEEK thus locking the bone screws to the body. A major diameter of a bone screw increases towards the head of the screw to cause interference between the PEEK body and the screw. This aids in preventing the screw from backing out of the body. Bone screw holes are angled to project the bone screw from either the top or the bottom of the body for receipt in upper and lower vertebral bone. Preferably, but not necessarily, the direction of the bone screw bores are staggered from one lateral side to another lateral side of the body.

This interphalangeal arthrodesis implant comprises a proximal anchor portion intended to be engaged and anchored in the medullary canal of a first phalanx sectioned along a first osteotomy plane, the proximal anchor portion including a plurality of proximal anchor branches each provided with at least one bone anchor element; and a distal anchor portion, connected to the proximal anchor portion, intended to be engaged and anchored in the medullary canal of a second phalanx sectioned along a second osteotomy plane, the distal anchor portion including a plurality of distal anchor branches each provided with at least one bone anchor element. The distal anchor portion comprises a stop portion including a stop surface intended to bear against a sectioned surface of the first phalanx extending along the first osteotomy plane.

A sacroiliac fusion stabilizer (SIFS) for fusing a first bone fracture fragment to a second bone fracture fragment is provided. In one embodiment, the SIFS has a lazy-S shape with a series of protrusions at the ends of the SIFS. In another embodiment, the SIFS has two overlapping lazy-S shapes.
