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: A cerclage system used to affix a bone includes a tension plate, a cable lock, and a cerclage cable configured to encircle the bone. The tension plate, which is engageable with the cerclage cable, is moveable between a natural shape and an insertion shape where the tension plate stores energy. The cable lock locks the cerclage cable about the bone in engagement with the tension plate. The tension plate is configured for positioning atop the bone while residing in the insertion shape. The tension plate, through an engagement thereof with the cerclage cable and upon attempted movement thereof from the insertion shape toward the natural shape, delivers the energy stored therein to the cerclage cable thereby tensioning the cerclage cable such that the cerclage system continuously compresses the bone.

Abstract: An expandable implant system is configured to increase the height of a target bone, for instance that has been subjected to a compression fracture. The expandable implant system includes an implant assembly that can be inserted into the target bone, and subsequently expanded so as to increase the height of the target bone. The expandable implant system further includes an and insertion assembly that is configured to create an insertion channel into the target bone, such that the implant assembly can be inserted in a collapsed configuration into the target bone along the insertion channel, and subsequently expanded.

Abstract: A stem portion is formed such that when implanted in a scapula the stem portion includes three cross-sections parallel to a medial lateral plane.

Abstract: Skin compression devices are disclosed that are formed of a shape memory material and that have multiple tensioning members. Disposal of one or more skin compression devices on the skin of a subject increases the temperature of the shape memory material and causes the tensioning members to bend inward, thereby compressing the area of skin disposed between the tensioning members; this compression shields the compressed skin from tensile loading. Methods of production and use of the skin compression devices are also disclosed.

Abstract: Sensor-enabled surgical retractor devices, systems, and methods are disclosed herein that can be coupled to a surgical robot during a robotic or robot-assisted surgical procedure to maintain health of retracted anatomy and prolong the amount of time until a surgical procedure must be interrupted to adjust a retractor. In some embodiments, interruption of a surgical procedure can be avoided by providing for minor and, in some cases, automatically administered, adjustment of retractor devices to alleviate pressure on retracted tissue without requiring surgeon attention or intervention. Fine (e.g., minor) adjustments to the retractor can be made automatically over the course of a surgical procedure to prevent damage to retracted anatomy and increase the time until a major adjustment of the retractor is needed.
