An intervertebral implant is disclosed. The implant can be made of Titanium or alloys thereof. A kit of intervertebral implants can be included having different lordotic profiles or having no lordotic profile. The intervertebral implants of the kit have endplates with thicknesses suitable to prevent the titanium endplates from being too stiff. The intervertebral implants can have apertures that extend through the endplates, but sufficient surface area at the outer surfaces of the endplates to avoid subsidence into the respective vertebral body.

A system for treating dysfunctional SI joints that includes a multi-function bone structure prosthesis adapted to be delivered to and inserted into a dysfunctional SI joint via a posterior approach, the multi-function bone structure prosthesis, when disposed in a dysfunctional SI joint, being adapted to (i) stabilize the dysfunctional SI joint, (ii) induce proliferation, and/or growth and/or remodeling and/or regeneration of osseous tissue and, thereby, healing and arthrodesis of the dysfunctional SI joint, (iii) attenuate pain associated with the dysfunctional SI joint via neurostimulation, and (iv) monitor physiological and/or biomechanical parameters associated with the dysfunctional SI joint via one or more sensor systems.

Prostheses are described for stabilizing dysfunctional sacroiliac (SI) joints. The prostheses are sized and configured to be press-fit into surgically created pilot SI joint openings in dysfunctional SI joint structures. The prostheses have a pontoon shape with opposed elongated partially cylindrical sections connected by a bridge section. The partially cylindrical sections and, in some instances, the bridge section have a porous structure.

A system and method for facilitating the treatment of lumbar degenerative disc disease. The method comprising making an incision posterolaterally along an annulus fibrosus of a specimen, removing nucleus pulposus from the specimen with tissue removing tools, and pushing magnetic spherical beads into a nuclear area within the specimen. The system comprises the specimen with the nuclear area, a plurality of magnetic spherical beads, tissue removal tools, a hollow cannula and a non-magnetic rod. The hollow cannula and non-magnetic rod configured for pushing the magnetic spherical beads within the nuclear area after incision.

A bone material dispensing device is provided. The bone material dispensing device comprises a housing having a proximal end, a distal end, and a longitudinal axis. The proximal end has a first opening and the distal end has a second opening. The first opening and the second opening are configured to slidably receive at least a portion of a plunger. A tubular member is provided that is pivotably connected to the housing and is configured for lateral movement relative to the longitudinal axis of the housing. The tubular member comprises a proximal opening, a distal opening and a channel disposed therebetween. The proximal opening, the distal opening and the channel of the tubular member are configured to receive at least the portion of the plunger. The tubular member is movable in a first position to align the proximal opening of the tubular member with the second opening of the housing to allow the tubular member to receive at least the portion of the plunger to dispense the bone material. A method of implanting bone material with the bone material dispensing device is also provided.

A tool for delivery and/or compaction of bone graft material includes a cannula with an inner lumen extending along a longitudinal axis from a hopper end of the cannula to a delivery tip of the cannula. A hopper with an internal volume for storing bone graft material is connected to the hopper end of the cannula with the internal volume of the hopper in communication with the inner lumen of the cannula for delivery of bone graft material from the hopper to the delivery tip of the cannula. An output shaft within the inner lumen extends along the longitudinal axis. The output shaft includes a helical screw thread extending radially outward from the output shaft toward an inner surface of the cannula. An actuator is connected to the hopper and to the output shaft to drive the output shaft rotationally relative to the hopper and to the cannula.

A predetermined bone site in a patient selected for restoration is exposed, contacted with an aqueous, methylene blue containing phosphoric acid solution for a time period of at least 3 minutes but no more than about 15 minutes, and thereafter cleansed ultrasonically to remove any bacteria that may be present. Preferred phosphoric acid concentration in the aqueous solution is about 37 percent by weight.

An intervertebral fusion cage is disclosed. An intervertebral fusion cage according to an embodiment of the present invention comprises: a body including a receiving part of which upper and lower portions are open, an upper guide part, and a lower guide part; a moving member disposed in the receiving part; a screw which is screw-coupled to the body and moves forwards or backwards relative to the body integrally with the moving member when rotating; an upper plate which has a guided part guided by the upper guide part and is disposed above the body while being engaged with the moving member; and a lower plate which has a guided part guided by the lower guide part and is disposed under the body while being engaged with the moving member.

A prosthetic device can include a neck defining an upper surface and a sidewall extending from the upper surface, an opening defined by the sidewall and extending into the neck, one or more interior surfaces extending into the neck from the opening to define a female receiving cavity, and a radial head including a male protrusion received within the female receiving cavity through the opening.

A cortical shaft bone fixation apparatus includes a housing having a leading portion and a trailing portion, the leading portion configured to fit within a diameter of an affected cortical shaft bone, the leading portion having first and second sections. The apparatus further includes an expansion mechanism adapted to transition the first and second sections from a first position to a second position, the first and second sections providing an outward force against the inside surface of the cortical shaft bone when the first and second sections transition from the first position to the second position, the trailing portion of the housing abutting a leading end of the affected cortical shaft bone. The trailing portion of the housing includes a pair of angled tapers extending inwardly toward each other to a minimum separation distance at an extreme end of the housing.
