    摘要： A vertebral rod for stabilizing a patient's spine. The rod may include an elongated body with first and second ends and have an elongated cross-sectional shape with a major axis and a minor axis and a centroid positioned at an intersection of the axes. First and second longitudinal channels may extend through the body. The channels may be spaced apart and contained within the body. The body may have a first flexural rigidity along the major axis and a different second flexural rigidity along the minor axis.

    摘要： One nonlimiting embodiment of the present application is directed to a system for positioning a connecting element adjacent one or more bones or bony portions, such as the spinal column, through a minimally invasive surgical approach. The system generally includes a number of bone anchors engageable to the one or more bones or bony portions and a number of anchor extenders removably engaged to the bone anchors. A connecting element inserter instrument is engageable with one of the anchor extenders and is movable along a longitudinal axis of the anchor extender. As the inserter instrument is moved along the longitudinal axis toward the bone anchors, a leading end of the connecting element is rotated away from the longitudinal axis and the connecting element is positioned at a location adjacent the number of bone anchors in a minimally invasive surgical procedure. However, in other embodiments, different forms and applications are envisioned.

    摘要： Methods of assembling a vertebral anchor to a body shaped to receive a longitudinal member. The methods may include inserting a wear member and a head of an anchor into a cavity through an inlet in a first end of a body. The body may further include a second end with a channel to receive the longitudinal member. The method may include deforming the first end of the body and reducing a width of the inlet measured perpendicular to a longitudinal axis of the body and capturing the wear member and the head in the cavity. The method may also include compressing the wear member against the head of the anchor and increasing an amount of interference between the wear member and the head.

    摘要： Systems, devices and methods are provided for bending an elongate member used in a medical procedure. In one form, the device includes a bending mechanism having a plurality of engaging members are selectively positioned relative to a receiving area. In one embodiment, a first set of engaging members is positioned in a select arrangement, and a second set of the engaging members is movable relative to the select arrangement of the first set of engaging members to compressingly engage the elongate member to bend the elongate member to a desired shape/contour. The device also includes a heating element configured to apply heat to one or more portions of the elongate member to facilitate bending. In one form, the elongate member is formed of a heat deformable material, and heat is applied to soften one or more portions of the elongate member to provide added flexibility to facilitate bending.

    摘要： The present invention concerns spinal fixation systems, and particularly systems utilizing pedicle screws, connectors and elongated members positioned adjacent to the spinal column. More specifically, the invention concerns improvements to spinal connectors having set screws used to connect to the elongate members, such as spinal rods, that include a means for inhibiting rotational movement of a partially inserted set screw before such connectors are implanted by the surgeon.

    摘要： Instruments and methods include a guide instrument mountable to at least one anchor extension to guide the positioning of an anchor in a bony segment. The guide instrument facilitates aligning the anchor with one or more other anchors already engaged to the bony segment. The anchors can then be engaged with a connecting element extending therebetween. The guide instrument facilitates multi-level fixation of bony segments with bone anchors and one or more connecting elements in a minimally invasive surgical approach.
