The shim-type implant for distraction and fusion of cervical facet joints is provided. The implant has a generally box-like shape with a blunt leading edge that may be centered or offset to the inferior face. The implant may include a graft window for enhanced osseous through-growth after implantation. The implant is coated with hydroxyapatite (HA) and/or tri-calcium phosphate (TCP) to allow for osteo-conduction, is porous, and has a roughened surface with serrations on the superior and inferior faces. The implant may be fabricated from a titanium or tantalum alloy. In an embodiment, a set of tools is provided with a chisel and one or tongs and one or more decorticators for inserting the implant.

An intervertebral implant for being implanted between adjacent vertebrae is provided. The implant includes a generally elongate implant body having a length extending between opposite longitudinal ends thereof, a superior face and an inferior face. The superior face and inferior face include cortical teeth adjacent to the implant body longitudinal ends. Additionally, the superior and inferior faces include longitudinally central teeth intermediate the cortical teeth and have bone engaging ends. The central teeth have a sharper configuration than that of the cortical teeth bone engaging ends for biting into the softer central bone material of the vertebrae. The cortical teeth are arranged in a first density per unit area and the central teeth are arranged in a second density per unit area that is less than the first density.

The present invention is directed generally to (1) an articulating junction, and articulation method thereof, wherein articulation is facilitated by a plurality of magnetic particles; (2) an articulating junction, and articulation method thereof, wherein the stability and fluidity of the junction is based, at least in part, on the magnetic field(s) of the plurality of magnetic particles; and (3) reducing the resistance to articulation and/or increasing the structural integrity and support, of the articulating junction, via electro-magnetism. Further, the present invention is directed generally to the synergistic combination of magnetic particles and preferred bio-implant-materials and additive-manufacturing methods along with Baker correlation codes. Further, the present invention is directed to an artificial joint for implantation into a living body and methods for constructing such an artificial joint.

Systems and methods of identifying a coating on a bone material are provided. The systems and methods comprise providing a bone material and a scanning device; adjusting a distance between the bone material and the scanning device; scanning the bone material using the scanning device; and transmitting a scanned data from the scanning device to a processor configured to analyze the scanned data, and display the analyzed scanned data to identify the coating on the bone material based on the scanned data when the coating meets or fails to meet a predetermined parameter.

An interbody spinal implant including a body having a top surface, a bottom surface, opposing lateral sides, and opposing anterior and posterior portions. At least a portion of the top surface, the bottom surface, or both surfaces has a roughened surface topography including both micro features and nano features, without sharp teeth that risk damage to bone structures, adapted to grip bone through friction generated when the implant is placed between two vertebrae and to inhibit migration of the implant. The roughened surface topography typically further includes macro features and the macro features, micro features, and nano features overlap. Also disclosed are methods of using such implants and processes of fabricating a roughened surface topography on a surface of an implant. The process includes separate and sequential macro processing, micro processing, and nano processing steps.

Systems and methods are provided for generating microscale structures and/or nanoscale structures, surface profiles, and surface chemistries on medical devices. Embodiments disclosed herein utilize exposure of pulsed laser radiation on to a surface of a material by a pulsed laser. The pulsed laser according to embodiments disclosed herein is configured to emit at least one laser pulse toward the surface and thereby modify the profile of the surface in order to selectively promote or inhibit bioactivity and medical functionality of the material. By selectively promoting or inhibiting bioactivity of the material, enhanced biointegration at a cellular level may be achieved. For example, modifying the surface profile and/or surface chemistry of a first substrate material can improve adhesive and/or chemical bonding of the first material to a bioactive second coating material.

Implants, systems, instruments, methods, and kits for metatarsophalangeal joint arthroplasty may include metatarsal arthroplasty implants, repositioning guides, broach tools, inserter tools, and sterilizable packaging configured to facilitate metatarsal arthroplasty surgical procedures. The metatarsal arthroplasty implants may generally include an articular member having a convex articular surface, a concave bone-facing surface opposite the convex articular surface, and at least one side surface intermediate the convex articular surface and the concave bone-facing surface, as well as a central shaft sized for insertion into a metatarsal bone having a central shaft longitudinal axis, a central shaft proximal end coupled to the concave bone-facing surface of the articular member, and a central shaft distal end extending away from the concave bone-facing surface of the articular member along the central shaft longitudinal axis.

A scaffold comprised of a plurality of PLLA layers, which may include stem cells, for regenerating bone or tissue. The PLLA layers are separated by a plurality of hydrogel layers. The PLLA layers comprise a nanofiber mesh having a piezoelectric constant to apply an electrical charge to the bone or tissue upon application of ultrasound energy.

Disclosed are compositions, methods and processes for fabricating and using a device or other implement including a surface or surfaces having a nanoscale or microscale layer or coating of Si—O—N—P. These coatings and/or layers may be continuous, on the surface or discontinuous (e.g., patterned, grooved), and may be provided on silica surfaces, metal (e.g., titanium), ceramic, and combination/hybrid materials. Methods of producing an implantable device, such as a load-bearing or non-load-bearing device, such as a bone or other structural implant device (load-bearing), are also presented. Craniofacial, osteogenic and disordered bone regeneration (osteoporosis) uses and applications of devices that include at least one surface that is treated to include a nanoscale or microscale layer or coating of Si—O—N—P are also provided. Methods of using the treated and/or coated devices to enhance enhanced vascularization and healing at a treated surface of a device in vivo, is also presented.

Orthopedic implants produced by additive manufacture, followed by refinement of exterior and interior surfaces trough mechanical erosion, chemical erosion, or a combination of mechanical and chemical erosion. Surface refinement removes debris, and also produces bone-growth enhancing micro-scale and nano-scale structures.
