Methods of making articles with a 3D printer using biomaterials that retain physical properties and biological activity are discussed. Methods can include providing a crosslinkable material and a biomaterial to a 3D printer, and crosslinking the materials to form an implant. Biomaterials can include, among other things, bone, or tissue.

The present invention relates to a biomaterial comprising adipose-derived stem cells (ASCs), a ceramic material and an extracellular matrix. In particular, the biomaterial according the present invention secretes osteoprotegerin (OPG), and comprises insulin-like growth factor (IGF1) and stromal cell-derived factor 1-alpha (SDF-1α). The present invention also relates to methods for producing the biomaterial and uses thereof.

A bone implant comprising cancellous bone that is essentially free of blood cells, and which has been treated with at least a loosening agent, such as collagenase and/or a digestive enzyme, for a time and at a concentration to loosen the osteogenic cells in the cancellous bone matrix. The osteogenic cells in the matrix are viable cells. The treatment of the cancellous bone with at least one loosening agent enables the osteogenic cells to be more available for carrying out their osteogenic function and to provide for an increased rate of bone formation.

Embodiments disclosed herein relate scaffolds containing fluoridated apatites sintered at a temperature of at least 950° C. and with at least one integration aid to increase integration of the scaffold in a patient, as well as methods of making and using the same.

An injectable composite material for bone repair comprises a biological tissue material and bioceramics in order to serve as a three-dimensional scaffold for bone regeneration. The biological tissue material consists of microfibers having a naturally cross-linked structure without additional physical or chemical cross-linking, has superior biological compatibility, and can be slowly and completely degraded in vivo. The bioceramics in the composite material serves as a reinforcing phase. When combining the biological tissue material with the bioceramics, the composite material provides a template for bone tissue regeneration to effectively induce bone growth. The injectable composite material for bone repair can be used to fill bone defects, particularly critical-sized bone defects, and can be combined with a biological agent such as bone marrow to improve its biological activity. Therefore, the composite material can be widely used to repair bone defects caused by trauma, tumor resection, osteonecrosis, and infection.

Methods for making surgical implants (or grafts) for the repair of bone defects, and more particularly, surgical implants that include demineralized bone fibers, are disclosed. Also disclosed are methods for increasing the wettability and ensuring uniform density of such implants. The surgical implants have a wettability time of less than 5 minutes and a residual moisture content of less than 6% by weight, and they remain cohesive and retain their shape upon complete rehydration.

A bone graft composition comprising a viable, osteogenic cellular material combined with a viscous cryoprotectant that includes a penetrating cryoprotective agent and a non-penetrating cryoprotective agent. The viscosity of the cryoprotectant is such that the composition is malleable, cohesive and capable of being formed into desired shapes.

An autologous bone graft substitute composition for inducing new bone formation, promoting bone growth and treating bone defects, a method of preparation thereof, and a method of inducing or promoting bone growth by treatment of a bone with an autologous bone graft substitute composition. The composition includes autologous blood; one or more analogs of an osteogenic bone morphogenetic protein selected from BMP-6, BMP-2, BMP-7, BMP-4, BMP-5, BMP-8, BMP-9, BMP-12, and BMP-13, and combinations thereof; and a compression resistant matrix selected from the group consisting of a bone autograft, bone allograft, hydroxyapatite, tri-calcium phosphate, and combinations thereof. The autologous blood forms a coagulum gel comprising a fibrin-meshwork reinforced with the compression resistant matrix and containing the osteogenic bone morphogenetic protein which is released over a sustained period.

A composition and methods of making or use thereof include a plurality of fibers forming a shape for augmenting fixation of a bone screw, or the plurality of fibers form a shape having a peg portion and a sheet portion to augment tendon to bone repair. The physical presence of the plurality of fibers provides initial fixation, while the use of an osteoinductive material provides long term enhancement of bone formation around the site of the bone screw or the tendon to bone repair.

A method for instant lumbar spine fusion between two vertebrae in a patient includes establishing under X-ray fluoroscopy the location of the transpedicular notch of the next lower vertebra in caudal direction, making a percutaneous incision to the transpedicular notch, inserting a cannulated guide, drilling a transpedicular approach from the pedicle of the lower vertebra to the anterior part of the vertebral body of the vertebrae above the disc to be treated, inserting a working cannula through the previously drilled approach reaching the intervertebral disk, cleaning and scrapping the intervertebral disk space, inserting transpedicularly at least one intervertebral stabilizing screw, and acting on both intervertebral screws with screwdrivers in order to distract or contract both screws allowing to adjust or correct the intervertebral distance of the disk. The method can be performed on an outpatient basis.
