Intervertebral implant with blades for connecting to adjacent vertebral bodies
An intervertebral implant for insertion into an intervertebral disc space between adjacent vertebral bodies or between two bone portions. The implant includes a spacer portion, a plate portion operatively coupled to the spacer portion and one or more blades for securing the implant to the adjacent vertebral bodies. The blades preferably include superior and inferior cylindrical pins for engaging the adjacent vertebral bodies. The implant may be configured to be inserted via a direct lateral trans-psoas approach. Alternatively, the implant may be configured for insertion via an anterior approach.
ANKLE REPLACEMENT SYSTEM
A prosthesis suited for orthopedic implantation possesses a multi-piece stem component that supports an artificial joint surface that can articulate with another artificial joint surface in various ways. The prosthesis can be assembled in a snap fit and/or interlocking fashion that provides positive locking means without the use of screws or other fasteners. The prosthesis can accommodate fitment of a plastic joint surface made, e.g., from ultra high molecular weight polyethylene. The prosthesis is well suited for use in an ankle replacement system that can be installed using minimally invasive intramedullary guidance established with respect to the major axis of the tibia by minimally invasive access through the calcaneus, through an incision in the bottom of the foot. The prosthesis makes possible the installation of a total ankle system using minimally invasive anterior access to the ankle joint for making bony cuts and to install prosthesis components.

CONTINUOUS FIBER-REINFORCED BUILD MATERIAL FOR ADDITIVE MANUFACTURING
A continuous fiber-reinforced build material for additive manufacturing (AM) of fiber-reinforced composite (FRC) structures, a machine for the preparation of the build material, and use of the build material for manufacturing of three-dimensional (3D) FRC end-product devices, such as medical devices for management of musculoskeletal and dental disorders.
BIOACTIVE CRYSTALLIZED GLASS CERAMIC COMPRISING WOLLASTONITE, HYDROXYAPATITE AND DIOPSIDE, AND USE THEREOF
The present invention relates to a glass ceramic composition comprising SiO.sub.2, Ca(OH).sub.2, CaF.sub.2, B.sub.2O.sub.3, MgO, and hydroxyapatite; a bioactive crystallized glass ceramic comprising each of CaSiO.sub.3, Ca.sub.10(PO.sub.4).sub.6(OH).sub.2, and CaMgSi.sub.2O.sub.6 in an amount of 20% to 60% by weight; an implant for early osseointegration comprising the glass ceramic; and a method for manufacturing the implant.
Systems and techniques for restoring and maintaining intervertebral anatomy
Techniques and systems for distracting a spinal disc space and supporting adjacent vertebrae are provided. Trial instruments are insertable into the disc space to determine a desired disc space height and to select a corresponding implant. Implants can be also be self-distracting and the implant providing the desired disc space height can be implanted in the spinal disc space.
Spine stabilization device
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.
Bone implant
The present invention provides a technological platform for bone regeneration. More specifically, the invention provides an implant comprising a plurality of polymeric casings at least one of which encases a bone void filler and at least one reinforcement component. Also provided is a method of regenerating bone by implanting one or more implants according to the present invention to a bone repair site.
STABILIZING VERTEBRAE WITH ARTICULATING IMPLANTS
A bone joint spacer has two endplates which have a bone engaging surface on one side, and ramps extending from an opposite side. A shaft has a threaded end, and another end which has ramp followers which mate with the endplate ramps of both endplates. A collar slides over the threaded end of the shaft, and also has ramp followers which mate with the endplate ramps of both endplates. A nut threads onto the end of the shaft and pushes the collar towards the ramp followers of the shaft. This movement causes the ramp followers to slide the ramp followers of the collar and the shaft against the endplate ramps, pushing the endplates apart. Two of these spacers can be combined by a link plate so that the spacers can be aligned or curved into a U-shape to be inserted into the body and positioned between bony surfaces, respectively.
