摘要： A receiver assembly for securing an elongate rod to a bone anchor including a receiver and a threaded plug. The receiver including an upper portion defining a channel to receive the elongate rod, an interior surface having helically wound receiver thread, and an exterior surface having first and second horizontal curvate extending instrument engaging grooves. The threaded plug including a longitudinal axis, a lower surface having a protrusion, and an external side surface having a continuous helically wound closure thread to rotatably mate with the helically wound receiver thread. The continuous helically wound closure thread including a lower leading surface and an upper trailing surface, both extending perpendicular to the longitudinal axis, and a cylindrical outer crest surface extending parallel to the longitudinal axis. When the protrusion on the threaded plug engages the elongate rod, the threaded plug does not extend overtop a top surface of the receiver.

摘要： The invention relates to a bone anchor for triangular iliosacral osteosynthesis. The bone anchor includes an ilium screw having a first longitudinal direction and an iliosacral screw having a second longitudinal direction. The ilium screw, in a thread-free portion, has a preferably elongated-hole-like through-opening transversely to the first longitudinal direction, and the iliosacral screw has such a smaller outer diameter in relation to the ilium screw that the iliosacral screw can be guided through the through-opening and can be screwed proceeding from the ilium into the sacrum, through the ilium screw.

摘要： Methods and apparatus for immobilizing a synovial joint, such as a sacroiliac (SI) joint are disclosed. In one form, a multipiece fixation device, such as a dowel, includes multiple expandable fasteners that are configured to fix adjacent bones of a synovial joint with respect to one another. The expandable fasteners include expansion portions that are expanded radially via insertion of another expandable fastener or an expansion device to fix the expandable fasteners to the bone. The fixation device may be configured to provide for compression or distraction of the bones of the synovial joint while at the same time stabilizing the joint.

摘要： A surgical screw configured to expand and prevent or minimize bone growth inside of the surgical screw is provided. Accordingly, the surgical screw is configured to increase the purchase of the surgical screw with respect to the bone, but also to be withdrawn from the bone without damaging the bone as a result of bone ingrowth. The surgical screw includes a center post with an inner bore and an outer sleeve concentric to the center post. An outer surface of the outer sleeve includes a thread to engage bone. The outer sleeve includes a cut pattern defining an expandable region configurable between a first state with a first radius measured from a longitudinal axis of the surgical screw to the outer surface and a second state having a second radius measured from the longitudinal axis to the outer surface.

摘要： The present invention provides processes for combined applications of making grooves on an implant surface, applying MgO nanoparticles with PMMA cement, restricting the cement movement by PCL nanofiber and tethering biomolecules with PCL nanofiber to enhance mechanical stability and osseointegration of PMMA cement with bone. This is achieved through enhanced osteoconductive properties, roughness, and less viable fracture originating sites at the bone-cement interface. Such combined applications of nanoparticle and nanofiber on the mechanical stability and osseointegration of cemented implant is heretofore unknown, but as provided by the present invention can solve the debonding problem of cemented implant from bone.

摘要： In an exemplary embodiment, the present invention provides an anchor assembly that can be used for the fixation or fastening of orthopedic devices or instruments to bone tissue. In particular, the present invention preferably provides a variable angle or fixed angle anchor assembly that is able to securely connect the orthopedic device to bone tissue even when there is a variance in the angle and position of the assembly with respect to the device. Furthermore, in an exemplary embodiment, the present invention provides an anchor assembly having a locking mechanism that will quickly and easily lock the anchor assembly with respect to the orthopedic device.

摘要： A bone anchoring element comprising a shaft (2) for anchoring in a bone, with a plurality of barb elements (7) arranged in at least one helical line around the shaft axis (M) is described, wherein said barb elements are elastically movable relative to the shaft. The bone anchoring element (1) is easy to press into a core hole bore in a bone. The barb elements (7) act in a similar manner as do the threads on a conventional bone screw and thus provide for depth positioning. Moreover, the barb elements at the same time secure the bone anchoring element and prevent it from sliding-out.

摘要： A revisable orthopedic anchor and method of use for removably securing an anchor in bone, such as compromised or degenerated bone, is described herein. In one embodiment, the anchor makes use of dual probes and vector divergence of the distal tips of the probes to achieve superior bone purchase and pull-out resistance. In such an embodiment, the probes can be inserted one at a time into a hole formed in, for example, the pedicle bone. After the probes are inserted and joined at the proximal end, they have a greater pull-out resistance than a threaded anchor. Removing the anchor involves separating the proximal heads and reversing the implantation process. As a result of the unique bone anchor design disclosed herein, the devices and methods of the present invention allow for less complicated implantation and removal of orthopedic anchors, all while providing enhanced bone purchase when implanted in a patient.

摘要： Arcuate fixation members with varying configurations and/or features are provided, along with additional components for use therewith in provided intervertebral implants. The arcuate fixation members may be of different lengths, cross sectional geometries, and/or cross sectional areas. Applications of intervertebral implants utilizing arcuate fixation members are particularly suitable when a linear line-of-approach for delivering fixation members is undesirable.
