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: 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: A bone screw comprises a threaded shank including a distal end portion and a proximal end portion, and defining a first threaded section extending from the distal end portion toward the proximal end portion and adapted for anchoring in cancellous bone. A second threaded section extends contiguously from the first threaded section toward the proximal end portion The second threaded section has a finer thread pattern relative to the first threaded section. In one embodiment, the first threaded section includes a first helical threading defining a single lead thread pattern for anchoring in cancellous bone, and the second threaded section includes a second helical threading interleaved with the first threading to define a duel lead thread pattern for engagement in cortical bone. In a further embodiment, the bone screw includes a head portion extending from the threaded shank and configured for coupling to a spinal implant.

摘要: A lateral connector assembly for connecting a bone engaging fastener to an elongated member, such as a spinal rod includes a lateral connector having an opening for receiving a portion of the bone engaging fastener therethrough. The lateral connector includes a plate portion and an integral yoke portion, which yoke portion is attached to the elongated member by way of a clamp. The lateral connector assembly can include variable angle means between the clamp and the yoke portion of the lateral connector that permits rotation of the lateral connector about an axis projecting outward from the spinal rod. The clamp includes a tapering channel to capture the elongated member and lock the connector assembly.

摘要: A bio-compatible stabilization system includes one or more inserters and a connector for traversing a space between one or more bony structures. The stabilization system is designed to reduce or eliminate stress shielding effects while functioning as a tension band. The elastic properties of the connector can be selected and set on a per-patient basis to allow variance in range of motion and to tailor the connector to the particulars of a patient, i.e., age, gender, weight, height, condition, and the like.

摘要: A spinal stabilization rod includes a first rod portion having a proximal end and a distal end and having a first cross-sectional area. The second rod portion extends from the distal end of the first rod portion and has a second minimum cross-sectional area smaller than the first cross-sectional area. The second rod portion is formed of a first material and a different second material, with the first material being more resistant in shear than the second material. The implant also includes a slider portion disposed about and movable relative to the second rod portion.
