Abstract: A spinal screw assembly adapted to be secured to a vertebrae for providing securement across at least two vertebrae. The assembly includes a pedicle screw having a substantially spherical head portion, a threaded shaft portion, and an engagement surface in the head portion for driving said screw into the vertebrae, and a body member comprising a tower portion having an open top, a break-away section for manipulation of the screw upon implantation into the vertebrae, a base body at a proximal region of the body member and a break zone which acts as a transition between the base body and the tower portion. A resealably securable setscrew within the body member secures and fully contains the rod within said assembly. The break-away section remains completely outside a wound and is removed or broken off once the screw has been fully assembled inside the vertebrae.

Abstract: A nested dilation tube assembly for enabling implantation of a spinal screw assembly into a vertebrae is provided. The dilation tube assembly includes a plurality of dilation tubes. Each dilation tube includes an elongated cylindrical shaft with an outer diameter slightly larger than a preceding dilation tube. After being inserting into a body, the plurality of dilation tubes form a nested, concentric assembly enabling an opening placed in the spinal area and/or vertebrae to be enlarged up to the outer diameter of a last dilation tube. The inner dilation tubes are capable of being removed from outer dilation tubes such that the inner diameter of an inner most remaining dilation tube forms a space for receiving instruments and/or assemblies.

Abstract: A method of detecting osteoporosis in a mammalian is disclosed herein which includes: a) obtaining a sample of a bone related tissue or cells; and b) measuring the concentration of at least a marker which is either bacteria, bacteria produced factors, or HSPs. The method may further include comparing the concentration with concentrations from the same individual over a period of time or against a standard concentration. The marker may be a bacteria, a chaperone molecule, or a bacteria produced. Also provided herein is a method of treating or preventing osteoporosis caused by a bone disease which includes administering to a mammalian subject a therapeutically effective amount of a formulation which is either an HSP antigenic formulation or a bacterial antigenic formulation. The osteoporosis can be caused by a bone disease induced by bone infectious agents such as viruses, bacteria, fungi, protozoa and parasites.

Abstract: A resorbable interbody fusion device for use in spinal fixation is disclosed. The device is composed of 25–100% bioresorbable or resorbable material. The interbody fusion device of the invention can be in any convenient form, such as a wedge, screw or cage. Preferably, the resorbable device of the invention is in the shape of a tapered wedge or cone, which further desirably incorporates structural features such as serrations or threads better to anchor the device in the adjoining vertebrae. The preferred device further comprises a plurality of peripheral voids and more desirably a central void space therein, which may desirably be filled with a grafting material for facilitating bony development and/or spinal fusion, such as an autologous grafting material.

Abstract: A method by which immune responses to cortical bone grafts and other substrates (e.g., cement, IPN, etc.) can be minimized and at the same time graft osteoinductive potential can be improved, and improved graft substrate materials are disclosed. The method of the invention provides new types of bone grafts that incorporate into host bone more thoroughly and more rapidly, eliminating long-term complications, such as fracture, non-union, infection, and rejection. In the method of the invention, bone grafts or other substrates are modified to have an osteoinductive surface modification that the recipient's body will accept as its own tissue type and therefore will not reject or otherwise cause to fail. The osteoinductive surface modification comprises a biopolymer matrix coating that is seeded with periosteal cells that have been previously harvested either from the graft recipient or from an allogenic or xenogenic donor source.

Abstract: Bioresorbable osteoconductive compositions and methods of using the composition as a scaffold for bone repair in periodontal, alveolar or maxillary regeneration, bony cranial defects, and spinal regeneration are disclosed. The bioresorbable compositions contain a bioresorbable polymer, a micro or nano particulate filler and a pore creating substance. The bioresorbable polymer can be electronically unsaturated and cross-linkable with a cross-linking agent. The micro or nano filler can be any natural biocompatible material such as a metals, calcium carbonate, carbon, a biocompatible synthetic material, or a bioceramics such as hydroxyapatite. The pore creating substance can be an effervescent agent such as a carbonate and an acid.
