摘要： A dynamic spinal stabilization assembly includes at least one mounting collar with a bore therethrough along a longitudinal axis, and a spinal rod slidably extending through the bore. The bore includes a medially disposed first section of reduced size that tapers both inwardly and outwardly relative to the axis, and respective end sections of relatively larger size. The bore may be defined by an interior wall that convexly curves toward the axis in the first section, advantageously with a constant non-zero radius of curvature. The bore profile helps minimize potential binding that may occur between the collar and the rod. The rod is coupled to bone anchoring elements, with at least one such connection being via the collar.

摘要： Anchors to secure a rod to a vertebral member. The anchors may include a fastener with a distal end adapted to be connected to the vertebral member and a proximal end. A receiver may be operatively connected to the proximal end of the fastener. The receiver may include a channel sized to receive the rod. The receiver may further include at least one convex section that extends inward towards a longitudinal axis of the rod. The receiver may be formed in a unitary one-piece construction. The anchor may also include a securing member that connects to the receiver and may include a lower edge that extends into the channel and may contact the rod.

摘要： A dynamic spinal stabilization assembly includes a rod having a plurality of slidable collars thereon. The rod is mounted to at least one of the relevant bone anchoring element(s) via the collars. The collars are spaced from one another such that the bone anchoring element engages at least two collars. The collars may be arranged on the rod so that adjacent collars are longitudinally spaced from one another by a distance not more than one-half the length of the rod-receiving channel in the relevant bone anchoring element. There may be elastic elements slidably disposed on the rod between adjacent collars.

摘要： Devices to grasp a medical element that may include a first member, a second member that fits within the first member, and a locking element. The first and second members may move relative to one another to move the locking element between locked and unlocked positions. In an unlocked position, the device may move along the element. In the locked position, the device may lock to the element and motion is prevented. In one application, the device can be placed in the locked position to maintain a desired amount of tension on the element. Methods of grasping the medical element may include moving the first and second members relative to each other thereby moving the locking element to grasp and release the medical element.

摘要： Spinal support members having varying stiffnesses are disclosed. In one embodiment, an elongated spinal prosthetic includes a pair of curved elongated portions. The portions are formed of materials having different stiffness characteristics such that the stiffness of the prosthetic varies along its length. In another embodiment, an elongated spinal implant includes a pair of threadedly engaged elongated sections. The first section is formed of a first material having a first rigidity. The second section has an inner portion formed of the first material and an outer portion formed of a second material. The second material is less rigid than the first material. In another embodiment, a modular spinal rod is provided. The modular spinal rod includes a pair of connectable rod portions with different stiffness characteristics. In yet another embodiment, a kit for a modular spinal rod includes a plurality of connectable modular rod portions having different stiffness characteristics.
