    摘要： A bone screw for attaching a bone plate to bone includes a shank defining a lumen extending at least partially therethrough from a proximal end thereof, a head defining a lumen therethrough, and a rod member. The rod member is configured for insertion through the lumen of the head and into the lumen of the shank. The rod member is fixedly engageable with the shank and moveably coupled to the head such that both the rod member and the shank are moveable with respect to the head.

    摘要： A spinal plate system that maintains intervertebral spacing and spinal stability is provided. A spinal compression plate includes two or more plates (32,34) coupled together to form an adjustable-length plate. Movement of plates (32,34) in a spinal compression plate may be uni-directional. Compression of a spinal compression plate movement may mimic natural settling of bones in a spine and/or distribute at least a portion of a vertebral load to an implant positioned between two vertebrae. Maintaining at least a portion of the vertebral load on an insert may increase bone growth and increase fusion between an implant and surrounding vertebrae.
    A removable spacer (134) coupled to the spinal compression plate establishes an initial separation distance between a first plate (32) and a second plate (34) during an insertion procedure.

    摘要： Vertebra bodies in the human spine are stabilized through the use of minimally invasive surgery for the implantation of an elongate implant plate assembly (10) having spaced first and second screw receiving socket elements (13, 21) which are configured for respective attachment to first and second spaced vertebra with the aid ofbone fixation screws (17,23) and these elements are slidably received with respect to each other for adjustably changing the distance between the screw receiving socket elements (13, 21). A lock assembly is also provided for selectively locking the first and second screw receiving elements (13, 21) from further relative sliding. An elongate insertion tool (40, 40') is releaseably secured to the plate assembly (10), and the insertion tool is configured for manipulating the plate assembly as a whole and for remotely manipulating the screw receiving socket elements (13,21) for adjusting the distance therebetween. The plate assembly (10) is inserted through an incision and manipulated and advanced with the insertion tool (40,40') to provide minimally invasive insertion, and after fixation of the implant assembly with bone fixation screws (17, 23) is further utilized by remote manipulation to adjust the degree of compression on the vertebrae, and thereafter the implant plate assembly (10) is locked in position to prevent further relative movement between the screw receiving elements (13, 21) of the plate assembly.
