摘要:
Apparatus, methods, systems, procedures and implants for linking two or more anchors engaged to two or more vertebrae of a spinal column are provided. The systems include a plate assembly to stabilize one or more vertebral levels with first and second plate segments pivotally coupled to one another between anchors engaged to respective vertebrae of the vertebral level. The plate segments are manipulated to secure the plate segments to the respective vertebrae and lock the plate segments in position relative to one another.

Systems, instruments and methods are provided for bending an elongate spinal implant used in a medical procedure. In one form, an instrument for bending an elongate spinal implant includes a proximal handle portion and a bending mechanism having an implant engaging member movably coupled to the proximal handle portion. The bending mechanism is operable to articulate the implant engaging member relative to the proximal handle portion while a second implant engaging member associated with the articulating implant engaging member holding the elongate spinal implant in position. In another form, systems and methods are provided to bend in situ an elongate spinal implant associated with an orthopedic construct.

Apparatus and a method for assembly of panels into a composite structure are provided. The structure includes a form jig (1) having form boards (3, 4, 5) defining forming edges (6, 7, 8) against which a composite panel to be precisely formed may be drawn by a number of edge clamps (12), usually in combination with suction devices (26, 27, 28, 29, 30). The edge clamps (12) are able to extend around edges of the panel (13) for initial location of the panel against the form boards and subsequent more powerful drawing action to draw the panel into intimate contact with the forming edges of the form boards.

A spinal rod assembly may be formed by attaching an extension portion onto a spinal rod that extends along a longitudinal axis. The extension portion may include a rod coupler that attaches to the spinal rod with a first coupling that includes a first degree of rotational freedom and a first degree of translational freedom in positioning the rod coupler relative to the spinal rod along the longitudinal axis. The extension portion may further include an extender rod including an elongated rod body that may be secured to the rod coupler using a second coupling that includes at least a second degree of rotational freedom in positioning the extender rod relative to the rod coupler about an axis substantially perpendicular to the longitudinal axis. The extension portion may be assembled in situ to a spinal rod that has been previously secured to vertebral bodies in a patient.

A board to board interconnection is provided for interconnection of parallel stacked printed circuit boards, with a like array of plated through holes on each of the boards. One connector assembly is insertable from the outside of one of the stacked printed circuit boards, and another electrical connector assembly is insertable from the opposite side of the stacked parallel boards. One of the connector assemblies includes a compliant portion connectible with a plated through hole and including a socket contact. The other connector includes terminals with compliant portions for interconnection with the other board, and includes a pin terminal extending from the compliant portion which is insertable through the printed circuit boards and into interconnection with the socket of the other electrical connector assembly.

Embodiments of the invention include expandable, implantable devices and methods. Devices expand linearly to provide secure fixation between or among anatomical structures. The expanded height of some embodiments is greater that twice the unexpanded height of the device. In some embodiments, an implant replaces one or more vertebral bodies of the spine.

An instrument is provided for use in orthopedic surgery for reduction of a connecting member such as a spinal rod toward an implant such as a bone screw. An embodiment of the instrument includes handle portions that are pivotable relative to each other and biased apart, and arm portions pivotable relative to each other and to the handle portions. Distal portions of the arm portions, which may be offset from the arm portions, provide structure for engaging a connecting member and an implant. Squeezing the handle portions force the distal portions of the arm portions together, forcing together the connecting member and the implant. A toothed bar and pawl may be provided to retain the instrument in a squeezed state.

A bone anchor assembly is provided, which may be used in cervical, thoracic, lumbar or sacral areas of the spine or other orthopedic locations. The anchor assembly includes a bone engaging portion, a receiver, a saddle within a channel defined by the receiver, and an engaging member. The receiver extends along a central longitudinal axis and is fixed to the bone engaging portion. A rod or other elongated connecting element is received in a channel of the receiver in contact with the saddle, and the engaging member engages the connecting element against the saddle. The orientation of the saddle in the receiver is adjustable to correspond to the orientation of the connecting element relative to the central longitudinal axis at any one of a plurality of angles of the connecting element through the receiver while the receiver and bone engaging portion remain fixed relative to one another.
