The present invention is directed to (1) a plating system having multiple and single locking mechanisms for general skeletal use other than in the anterior cervical spine; (2) an orthopedic plating system that permits a pair of bone screws to be inserted into a bone in a crossed over orientation and locked to the plate; (3) a segmentable plating system which can be made to a selected length by the surgeon; and (4) a combination screw-lock-plating system for allowing and/or causing intersegmental compression of bone portions.

[ What is claimed is:] [1.] A skeletal plating system for aligning and maintaining bone portions of the same bone or of different bones in a selected spatial relationship for healing or fusion of the bone portions, comprising:a plate having a length sufficient to span at least two bone portions, said plate having an upper surface and a lower surface for placement against the bone portions, said lower surface being flat along a substantial portion of the longitudinal axis of said plate and being concave along the transverse axis of the plate, said plate having a plurality of bone screw receiving holes extending through said plate from said upper to lower surface, at least a first of said plurality of bone screw receiving holes associated with a first of the bone portions and at least a second of the said plurality of bone screw receiving holes associated with a second of the bone portions, said plate having a recess for retaining a locking element for locking bone screws in said bone screw receiving holes, said recess having a central longitudinal axis offset from a transverse line passing through the central longitudinal axes of said first and second bone screw receiving holes; anda multiple locking element for locking to said plate at least two bone screws insertable into one of said plurality of bone screw receiving holes, said locking element movably engageable in said recess and being movable from at least a first position to a second position, said locking element being configured so as to permit insertion of bone screws into each of said first and second bone screw receiving holes when in said first position, and said head bearing against at least a portion of at least one of said bone screws in said first and second bone screw receiving holes when moved to said second position.
