Abstract: Arcuate fixation members with varying configurations and/or features are provided, along with additional components for use therewith in provided fixation systems and intervertebral implant systems. The arcuate fixation members may be of varying lengths, cross sectional geometries, and/or cross sectional areas, and may be configured with various features such as heads configured to accept other fixation system components, tabs to allow arcuate fixation member-in-arcuate fixation member or fixation anchor-in-arcuate fixation member configurations. Applications of fixation systems and intervertebral implants systems utilizing arcuate fixation members are particularly suitable when a linear line-of-approach for delivering fixation members is undesirable.

Abstract: An assembly at a proximal end of an intravascular delivery system can allow the proximal end of a pull wire to move independently of a delivery tube. The assembly can generally include the pull wire, the delivery tube, a feature to prevent the proximal end of the pull wire from becoming inaccessible due to distal movement of the pull wire, and a feature to protect the proximal end of the pull wire from inadvertent, premature manipulation. When the intravascular delivery system is navigating tortuous vasculature, the proximal end of the pull wire can move distally in relation to the proximal end of delivery tube, relieving stress on the distal end of the pull wire. The proximal end of the pull wire can be protected from inadvertent manipulation during delivery and made available for manipulation once the distal end of the delivery system is in place.

Abstract: A system and method that acquire (i) at least a reference image including one of a preoperative image of a surgical site with skeletal and articulating bones and a contralateral image on an opposite side of the patient from the surgical site and (ii) at least an intraoperative image of the site after an implant has been affixed to the articulating bone. The system generates at least one reference landmark point on at least one anatomical feature on the articulating bone in the reference image and at least one intraoperative landmark point on that anatomical feature in the intraoperative image. The reference and intraoperative images are compared and differences between the orientation of the articulating bone in the two images are utilized to analyze at least one of offset and length differential.

Abstract: In one example a method of fracture reduction includes imaging, intraoperatively, a fractured bone of a patient to obtain a first representation of the fractured bone in a computing system. The fractured bone defines at least a first bone fragment, and a second bone fragment that is separated from the first bone fragment by a fracture. The method includes imaging, intraoperatively, a contralateral bone of the patient to obtain a second representation of the contralateral bone in the computing system. The method includes generating, intraoperatively in the computing system, a mirrored representation of the first representation or the second representation. The first representation is compared to a representation of a desired orientation of the fractured bone, where the representation of the desired orientation is the mirrored representation of the second representation.

Abstract: Disclosed is a joining element (10), especially a suture material for surgical use. The joining element (10) is composed of a first material (12) that is essentially rigid during impingement by a relatively short-lasting tensile load on opposite sides as well as a second material (11) which is connected to the first material. The second material is substantially rigid during impingement by said tensile load on opposite sides while contracting slowly during a second period of time that is longer than the first period of time.

Abstract: An implant for insertion into a disc space between vertebrae, wherein the implant includes a spacer portion, a plate portion coupled to the spacer portion, two bone fixation elements for engaging the vertebrae and a retention mechanism for preventing the bone fixation elements from postoperatively backing-out of the plate portion. The retention mechanism may be in the form of a spring biased snapper element that is biased into communication with the bone fixation elements so that once the bone fixation element advances past the snapper element, the snapper element is biased back to its initial position in which the snapper element interfaces with the bone fixation elements. Alternatively, the retention mechanism may be in the form of a propeller rotatable between a first position in which the bone fixation elements are insertable to a second position where the bone fixation elements are prevented from backing-out.
