    摘要： Apparatus and methods are disclosed for use within an image-guided surgical navigation system for the storage and measurement of trajectories for surgical instruments. An icon representing the real-time trajectory of a tracked instrument is overlaid on one or more pre-acquired images of the patient. At the surgeon's command, the navigation system can store multiple trajectories of the instrument and create a static icon representing each saved trajectory for display. The surgeon may also measure a planar angle between any two trajectories. The angle is computed in the plane of the image, and therefore will be computed separately for each image displayed. Furthermore, the surgeon has the option of computing and displaying the three-dimensional distance between two points defined by any two trajectories.

    摘要： An implant for a spinal column and a method for inserting the same into a patient is disclosed. The implant includes an elongated body positionable in a spinal disc space. The body comprises a first body member and a second body member that each include at least one wedge extending into an interior cavity. A front bracket is connected with a leading portion of the first and second body members and a rear bracket connected with a trailing portion of said first and second body members. The brackets allow the first and second body members to move between an expanded state and an unexpanded state. An expansion component is positioned within the interior cavity when the implant is in an expanded state and the implant is then positioned in an unexpanded state. The expansion component includes at least one inverted wedge in engagement with the wedge of the first and second body members. The inverted wedge is operable to cause the first and second body members to expand way from one another to the expanded state. A bone graft member is then inserted into the interior cavity defined by the first and second body members.

    摘要： An expandable containment device is provided for use in containing a flowable material. The containment device includes an expandable housing extending along a longitudinal axis and defining an interior region, and including a first housing portion movably engaged with a second housing portion to allow expansion of the housing generally along the longitudinal axis to provide the housing with an axial dimension extending between adjacent bone structures. The containment device further includes an input port in fluid communication with the interior region of the housing and configured to deliver a flowable material into the interior region of the housing.
