Systems and methods for preparing synthetic osteoinductive bone grafts are provided in which a porous ceramic granule, which may be incorporated within a biocompatible matrix material, is loaded with an osteoinductive agent. Loading of granules is facilitated in some cases by the use of low-pH buffers and pre-treatments.

Some aspects of the present disclosure relate to a surgical treatment for treating a tissue inside a vertebral column by forming a low-swelling biodegradable hydrogel in situ adherent to a tissue inside the vertebral column and substantially exterior to a theca in the vertebral column.

The disclosure provides bone graft materials, methods for their use and manufacture. Exemplary bone graft materials comprise combining a radiopaque component with a cancellous bone component to produce a bone graft material, wherein the cancellous bone component comprises native osteoreparative cells. Methods for treating a subject with the bone graft material are also provided.

The invention provides a method of producing a connective tissue graft suitable for correcting a connective tissue defect, comprising determining the size and shape of a tissue defect, obtaining a fat tissue from a patient modelled to fit the size and shape of the tissue defect, contacting the fat tissue with one or more connective tissue specific growth or differentiation factors; and kits for such a method.

The present invention provides novel compositions comprising multipotent cells or microvascular tissue, wherein the cells or tissue has been sterilized and/or treated to inactivated viruses, and related methods of using these compositions to treat or prevent tissue injury or disease in an allogeneic subject.

A spinal implant device has a synthetic or metallic or a combination thereof of these materials in an implant body structure and stem cells in a coating, or a sheet, wrap or a membrane wrap applied to surfaces on the implant body structure or alternatively filled with a plug of stem cell laden material. The implant body structure preferably has an aperture or channel The spinal implant device may include anchoring holes to secure the device to the spinal skeletal structure with fasteners or alternatively can simply be held in place by and between adjacent vertebrae.

Disclosed is a new use of a stem cell generator in preparation of bone defect repair materials, wherein the stem cell generator is formed by implanting a biomaterial with osteogenic induction capability or a biomaterial loaded with active substances and/or cells into an animal or a human body and generating organoids after development, the active substances are bone morphogenetic protein-2, or bone morphogenetic protein-7, other growth factors/polypeptides having bone regeneration induction ability, growth factors/polypeptide combinations, or a combination thereof. The cells are bone marrow-derived mesenchymal stem cells, adipose-derived mesenchymal stem cells or other derived mesenchymal stem cells; other types of cells with osteogenic differentiation capability; cells that aid in osteogenic differentiation of mesenchymal stem cells, such as vascular endothelial cells and the like. The stem cell generator is used to prepare bone repair materials for treatment of various types of bone defects or bone deformities that are spontaneous or caused by trauma.

The invention relates to a coating for an implant component, a method for producing an implant component having said coating, and a use of said coating on an implant component. The coating is intended for an implant component, in particular a spinal implant component, and is a TiNb coating which has, in addition to an atom % proportion of Ti and an atom % proportion of Nb, an atom % proportion of 5-30 atom % of Ag.

A pedicle screw implant construct kit, comprising at least one pedicle screw, at least one collar comprising a recess for receiving a rod, the collar configured to be coupled to a head of the pedicle screw, an elongated rod for connecting the collar to one more additional collars to couple between the pedicle screw and one or more additional screws, and a locking ring sized to be positioned over at least a distal portion of the collar to restrain relative movement of the screw head and rod by exerting radial compression force onto the collar. In some embodiments, the components of the kit are comprised of carbon reinforced composite material, optionally with no radiation blocking material. In some exemplary embodiments of the invention, the kit includes two locking rings on a collar, optionally both below the rod.

Embodiments of bony region stabilization and fusion constructs are described generally herein including bony fixation elements including porous, bone fusion enabling or promoting regions or osteo conductive enabling or promoting regions. Other embodiments may be described and claimed.
