  • Patent number: 8974465
    Abstract: In at least one embodiment of the present invention, a device for mixing and dispensing a bone cement mixture is provided. The device comprises a first chamber and a second chamber. The first chamber is for containing a first bone cement component. The second chamber is for containing a second bone cement component. A valve is in fluid communication with the first and second chambers. A first and a second plunger are respectively within the first and second chambers and are configured to actuate within their respective chambers. When the valve is in a first position actuating the first plunger advances the first bone cement component into the second chamber to form the bone cement mixture.

  • Patent number: 8974505
    Abstract: A cannulated and possibly fenestrated device for injection of material into bone can be dangerous because large, uncontrolled pressures are introduced during injection into a somewhat closed system, and material may extrude undesirably or emboli may be introduced. Methods and devices are described for providing venting of pressure upon injection of material through cannulated and possibly fenestrated screws. The first method involves a bone screw and/or anchor device that includes multiple channels to allow material to flow in through one channel and out through another channel. The second method involves a plunger that can force material into bone if advanced or lessen pressure if withdrawn. The third method involves usage of two separate screws. Material is alternately injected or withdrawn from each screw to cause material to flow from one screw to the other in a controlled way that creates a uniform or asymmetrical distribution of material as desired.

  • Patent number: 8968322
    Abstract: A method of repairing a fractured articular bone at a fracture site has the steps of mixing a bone glue, inserting an expandable balloon into the fracture site, inflating the expandable balloon at the fracture site, applying the bone glue to the fracture site while the expandable balloon is inflated, curing the bone glue at the fracture site while the expandable balloon is inflated, deflating the expandable balloon after the bone glue has cured, and removing the deflated expandable balloon from the fracture site and from the articular bone. The bone glue combines a biologically dissolvable glue with an actual or artificial particulate bone graft.

  • Patent number: 8951261
    Abstract: The embodiments provide devices and methods that both strengthen the bone and stimulate the bone. Bone fractures or non-unions are stabilized, integrated or healed, which results in reduction of a bone defect, such as a bone marrow lesion or edema. In addition, the distribution of forces in a joint are restored or altered to relieve pain. In general, a joint is evaluated by taking an image of the joint and one or more subchondral defects are detected. At least one of the subchondral defects may be diagnosed as the source of pain and an extent of treatment for the subchondral defect is determined. The disclosed devices and techniques are particularly suited for treating chronic defects or injuries, where the patient's natural healing response has not resolved the defect. The present disclosure also provides several exemplary treatment modalities for the different extents of treatment needed.

  • Patent number: 8951265
    Abstract: A fixation system configured to releasably secure an orthopedic implant to a bone. The fixation system including at least one expandable member that is inserted through the lumen and positioned in cancellous bone near the distal portion of the orthopedic implant. A delivery tube delivers a flowable biomaterial to the expandable member. The expand fixation structure includes at least one dimension greater than a corresponding dimension on the orthopedic implant to secure the orthopedic implant in the bone. An insert is secured in the lumen to releasably attach the fixation system to the orthopedic implant. The expandable member is detachable from the orthopedic implant to facilitate subsequent removal of the orthopedic implant from the bone.

  • Patent number: 8940046
    Abstract: The present invention relates to a method of implanting a prosthesis device in a subject. In one embodiment, this method involves: (i) providing a prosthesis device to be attached to an exposed surface of a bone; (ii) applying bone cement in liquid form to a bone-implant interface region, the bone-implant interface region including a region between the exposed surface of the bone and an outer surface of the prosthesis device; and (iii) contacting the bone cement to the exposed surface of the bone and the outer surface of the prosthesis device under conditions effective to allow the bone cement to cure, thereby resulting in attachment of the prosthesis device to the bone of the subject. The present invention also relates to a kit for implanting a prosthesis device in a subject, a method of performing a joint arthroplasty surgical procedure, and other methods of using bone cement in liquid form.
