ELECTRON BEAM IRRADIATED OSTEOINDUCTIVE BONE IMPLANT

A method of making an electron beam irradiated osteoinductive implant is provided. The method comprises exposing an osteoinductive implant containing demineralized bone matrix (DBM) fibers to electron beam radiation at a dose of from about 10 kilograys to 100 kilograys for a period of time. The electron beam irradiation reduces microorganisms in the osteoinductive implant, and the electron beam irradiated osteoinductive implant retains osteoinductive properties. Methods of implantation and an irradiated osteoinductive implant are also disclosed.

Allograft bone putty and methods of making the same

A method of preparing a reconstitutable implantable bone putty includes combining a bone matrix derived from human bone and gelatin particulates derived from human tissue at a concentration of the bone matrix by dry weight of 20 to 60 percent to form the reconstitutable implantable bone putty. Preparing the gelatin particulates includes supplying a gelatin precursor of bone or soft tissue from a human, treating the gelatin precursor with phosphoric acid to generate a gelatin-acid mixture, neutralizing the gelatin-acid mixture with an alkali to a pH between 6 and 8 to allow a gelatin-rich solution and a waste solution to separate, removing residual salts from the gelatin-rich solution to obtain purified gelatin, drying the purified gelatin, and reducing the purified gelatin to particulates having a largest dimension less than 300 μm. A method of preparing an implantable bone putty includes adding a reconstitution media to the reconstitutable implantable bone putty.

METHOD FOR INSTANT LUMBAR SPINE FUSION

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.

The grafts comprise a three-dimensional carrier matrix, a growth factor composition comprising an autologous platelet-rich fibrin and a cell culture composition comprising a culture medium, a population of cells suspended in the culture medium, and cells impregnated on or in a surface of osteoconductive particles.

Large 3D porous scaffolds made of active hydroxyapatite obtained by biomorphic transformation of natural structures and process for obtaining them

The present disclosure relates to a hydroxyapatite obtained from porous wood, having high compressive strength and dimensions suitable for clinical applications. The porous wood has a porosity of between about 60% and about 95%, said porosity being measured after subjecting the wood to a step of pyrolysis, and is selected from among rattan, pine, abachi, balsa, sipo, oak, rosewood, kempas and walnut wood. The hydroxyapatite may be substituted with one or more ions such as magnesium, strontium, silicon, titanium, carbonate, potassium, sodium, silver, gallium, copper, iron, zinc, manganese, europium, gadolinium. Also disclosed is a bone substitute comprising hydroxyapatite obtained from porous wood. The bone substitute is utilized for the substitution and regeneration of a bone or a bone portion, preferably for bones subjected to mechanical loads, such as long bones of the leg and arm, preferably the tibia, fibula, femur, humerus and radius. The invention relates also to a process for manufacturing a biomorphic hydroxyapatite scaffold from wood.

Phosphocalcic cement composition comprising blood

A method for promoting spine fusion inside intersomatic cages, comprising placing a fusion cage between two vertebral bodies, and injecting a bone cement paste inside said fusion cage, said bone cement paste containing a powder component comprising α-tricalcium phosphate (α-TCP) particles having an average size greater than or equal to 9 μm, and a liquid component comprising blood.
