Abstract: Instrumentation for retracting tissue comprising a retractor member including a sidewall defining an axial passage extending along a length thereof and a lateral opening in transverse communication with the passage. A pin member is disposed within the passage and includes a distal end portion positionable adjacent the distal end of the retractor member, with at least a portion of the pin member positioned adjacent and visible through the lateral opening. In another embodiment, the retractor member includes a sidewall having a main sidewall portion defining a first wall thickness, and an enlarged sidewall portion extending axially along a length of the sidewall and defining a second wall thickness greater than the first wall thickness, with the sidewall defining an axial passage extending through the enlarged sidewall portion. A pin member is disposed within the passage and includes a distal end portion positionable adjacent the distal end of the retractor member.

Abstract: A system and method of sending, receiving and managing messaging data through a shell interface is provided. The system includes a plurality of communication services, at least one messaging client and a host server. The plurality of communication services provides fax, voicemail and/or pager messaging services. The host server provides an interface between the messaging client and the plurality of communication services. The messaging client has a shell interface. A messaging component is installed into the shell interface. At least one messaging entry is displayed through the shell interface. The displayed messaging entry identifies received faxes, voicemails and/or pager messages. One of the received faxes, voicemails and pager messages is selected through the shell interface, and an appropriate communication service is invoked for accessing the selected message.

Abstract: Devices and methods for supporting adjacent spinous processes include opposing plates movable toward one another along a cross post to contact opposite sides of each of the spinous processes, and a spacer member about the cross post contacting the adjacent surfaces of the spinous processes to resist movement of the spinous processes toward one another under spinal extension motion.

Abstract: Systems and methods include an anchor engage able to a vertebra and an extender removably mounted to the anchor. The extender includes an insulating member extending at least partially thereabout to electrically insulate the extender and prevent shunting of electrical signals delivered through the extender to the anchor to structures adjacent the extender.

Abstract: A fixation device for use in association with ALIF procedures includes a couple of spaced plates having integral spikes on facing surfaces thereof for pressing into spinal processes of adjacent vertebrae. One of the plates has a spherical socket which captures a spherical head end of a post whose other end is received through an aperture in the other plate. The socket mounting is arranged to enable the post to pivot therein for at least two degrees of freedom to a limited extent, enabling angulation between the two plates so as to accommodate the different thicknesses and orientations of the spinal processes on adjacent vertebrae. The reception of the post in the second plate enables adjustment of spacing between the plates to accommodate effective installation of the assembly on the spinal processes by a compression instrument, and permanent reliable maintenance of that spacing following removal of the compression instrument.

Abstract: Systems and methods are provided that include a plate member engageable to the spinal column with an anchor assembly. The anchor assembly includes a coupling member having a post extending through at least one opening of the plate member and an anchor member pivotally captured in a receiver member of the coupling member below a lower surface of the plate member. A locking member secures the plate member to the coupling member. The coupling member includes an extended post with a proximal removable portion. The extended post facilitates placement of the plate member in position relative to the anchor assembly when engaged to the patient and be employed to reduce the plate member toward the anchor assembly when engaged to a vertebra.
