Abstract: An anchor-in-anchor fixation system is provided for securing underlying structure, such as bone. The fixation system includes a first bone anchor having a shaft for fixation to underlying bone, and a head that defines an internal bore. A second bone anchor extends through the bore and into underlying bone. A fixation assembly is also provided that includes one or more fixation systems coupled to an auxiliary attachment member configured for long bone fixation, spinal fixation, or fixation of other bones as desired.

Abstract: A bone fixation element comprises a shaft extending substantially along a longitudinal axis of the fixation element in combination with a head including a plurality of fixation element openings distributed about a perimeter thereof. Each of the fixation element openings extends through the head from a proximal surface thereof to a distal surface of the head. Each of the fixation element openings extends through the head along an opening axis.

Abstract: A flexible element that may be configured, among various uses, as an intervertebral implant for insertion into an intervertebral disc space between adjacent vertebral bodies or between two bone portions. The flexible element includes one or more struts extending from superior and inferior endplates and bending towards one another for connection with one or more internal beams.

Abstract: The present invention relates to dynamic bone fixation elements and a surgical method to stabilize bone or bone fragments. The dynamic bone fixation elements preferably include a bone engaging component and a load carrier engaging component. The bone engaging component preferably includes a plurality of threads for engaging a patient's bone and a lumen. The load carrier engaging component preferably includes a head portion for engaging a load carrier (e.g., bone plate) and a shaft portion. The shaft portion preferably at least partially extends into the lumen. Preferably at least a portion of an outer surface of the shaft portion is spaced away from at least a portion of an inner surface of the lumen via a gap so that the head portion can move with respect to the bone engaging component. The distal end of the shaft portion is preferably coupled to the lumen.
