The present teachings provide one or more surgical implements for repairing damaged tissue, such as in the case of a spinal fixation procedure. A bone anchor is provided. The anchor can include a bone fastener. The bone fastener can include a head and a second end adapted to engage an anatomy. The bone fastener can extend along a longitudinal axis. The anchor can also include a coupling arrangement coupled to the head of the bone fastener so that the bone fastener is rotatable about the longitudinal axis to define a first plane of motion. The anchor can further include a saddle, which can be coupled to the coupling arrangement. The saddle can be movable relative to at least one of the bone fastener and the coupling arrangement to define a second plane of motion.

Multiplanar bone anchor system

A method of stabilizing a portion of a spine includes pivoting first and second members of an expandable spinal implant relative to one another to a closed configuration in which the spinal implant has a compact profile, inserting the spinal implant in the closed configuration into the spine between first and second vertebral bodies, and pivoting and locking the first and second members crosswise to an expanded configuration while the spinal implant is within the spine. The first and second members are separate from and coupled to one another.

Method for stabilizing spine

An intervertebral implant and associated method. The intervertebral implant can include a first component having a first articulating surface and a first bone engagement surface for engaging a first vertebra, and a second component having a second articulating surface and a second bone engagement surface for engaging a second vertebra adjacent to the first vertebra. The first and second articulating surfaces articulate with each other for substantially replicating a natural spinal movement. The first and second bone engagement surfaces define an outer surface substantially shaped as an envelope of five cylinders.

An expandable spinal implant including a first member and a second member. The first member has first and second arms. The first and second members are pivotally coupled to each other for relative movement about a rotation axis between a closed position for inserting the implant into a spine and an expanded position for providing structural support to the spine. The expandable implant includes a locking mechanism for arresting relative movement between the first member and the second member.

Expandable spinal implant

An expandable spinal implant including a first member and a second member. The first member has first and second arms. The first and second arms of the first member both including an upper face partially defining an upper contact area of the implant and a lower face partially defining a lower contact surface of the implant. The second member has first and second arms that both include an upper face partially defining an upper contact area of the implant and a lower face partially defining a lower contact surface of the implant. The first and second members are pivotally coupled to each other for relative movement about a rotation axis between a closed position for inserting the implant into a spine and an expanded position for providing structural support to the spine. The rotation axis extends generally perpendicular to the upper and lower contact surfaces.

A method and a system for a spinal fixation incorporate a plurality of polydirectional fixation screws and a plurality of linkages. The polydirectional fixation screws include an upper member and a lower member. The upper member is attached to the linkage. The upper member includes a first hemispherical portion. The lower member engages the bone and includes a second hemispherical portion which cooperates with the first hemispherical portion to define a sphere. The second hemispherical portion is coupled to the first hemispherical portion for relative pivotal movement about an axis. Relative movement between the first and second hemispherical portions readily permits sagittal plane adjustments. The polydirectional fixation screw further includes a biasing member for biasing the first member away from the second member in a direction substantially parallel to the axis. The linkages are provided with various vertical offsets to readily permit coronal plane adjustment.
