    摘要: An iliac screw includes a smooth distal shank (35), a threaded proximal shank (37) and a proximal head portion (38). The smooth distal shank (35) is configured to penetrate the cancellous bone of the iliac wings, while the threaded shank (37) carries bone threads configured for engagement with the cortical or the cancellous bone. The head portion (38) is configured for engagement with an elongated fixation member, such as a spinal rod.

    摘要: One embodiment of the invention a spinal fixation system includes an elongated spinal element (11) configured to extend adjacent the spine, and a plurality of fixation elements (15) each engagable to the spine and to the elongated spinal element (11). The embodiment further includes an extension member (28) having a head portion (30) defining a variable angle surface and an elongated portion (29) extending from the head portion, and a clamping member (31) for clamping the extension member (28) to the elongated spinal element (11). The clamping member (31) defines a mating surface configured for mating engagement with the variable angle surface of the extension member (28) to permit orientation of the elongated portion (29) of the extension member (28) at a plurality of angles relative to the elongated spinal element (11).

    摘要: An inflatable corpectomy device includes a balloon, which defines a cavity for receiving a hardenable media. The device can be inserted in an un-inflated form into a space formerly occupied by a diseased or damaged vertebrae bone. When inflated with a hardenable material, the device expands and fills the space. Various bone anchors or plates can be used in combination with the inflatable device to bridge the space and stabilize the spine while the device hardens.
