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.

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:
The present invention relates to a brace installation instrument placement that is mounted to anchors secured in an animal subject. The installation instrument includes anchor extensions coupled to the anchors. The instrument is movable with respect to the anchors to position a brace in a position more proximate the anchors. The brace can be indexed for insertion at a predetermined orientation with respect to the installation instrument. Methods and techniques for using the installation instrument are also provided.
摘要:
Intravertebral reduction systems are provided to restore a deformed or damaged vertebral body to a desired configuration. The reduction systems can include a plurality of reduction elements sequentially positionable in the intravertebral space for reduction of the same. The reduction systems can also include reduction elements that include a linear insertion configuration and are deformable transversely to the linear insertion configuration in the intravertebral space.

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.

A device includes a sterilizing system configured to sterilize an implantable device and includes a coating system configured to apply an osteal functional coating to the implantable device.
摘要:
Techniques for spinal surgery include accessing at least one vertebral element of the spinal column. At least one loading member is engaged to the at least one vertebral element. The loading member is allowed to integrate with the bony structure of the vertebral element over time. The integrated loading member is accessed in a second surgical procedure, and can be loaded and/or attached to a construct.
