A fracture fixation plate system for use on a long bone having a metaphysis and a diaphysis, includes at least one end plate having a head portion for the metaphysis, and at least one diaphyseal plate having a first end and a second end with a plurality of screw holes therebetween. The end plate includes mating structure adapted to mate with and securely couple to at least one end of the at least one diaphyseal plate. The system preferably includes several end plates and diaphyseal plates to accommodate anatomy of various sizes. A method for coupling the plates to the bone is also provided.

1. A method of coupling a plurality of bone plates to a bone having a surface, comprising: a) first coupling first and second plates together separately from the bone;b) attaching the coupled first and second plates to the surface of the bone with a first cortical screw, the first cortical screw having a head that seats on the first plate; and thenc) further securing the coupled plates to the bone with a second cortical screw, the second cortical screw having a head that passes through the first plate and seats on the second plate above the surface of the bone. 2. A method according to claim 1, wherein: the first coupling includes inserting one end of the first plate into a socket in the second plate. 3. A method according to claim 1, further comprising: altering a rigidity of the second plate during the first coupling. 4. A method according to claim 1, wherein: after securing the coupled plates to the bone, further coupling the plates together with elements that do not extend into bone. 5. A method according to claim 4, wherein: the further coupling prevents backout of the first and second cortical screws. 6. A method according to claim 1, wherein: the first plate is a proximal metaphyseal humeral plate and the lower plate is a humeral diaphyseal plate. 7. A method of coupling a plurality of bone plates to a bone having a surface, comprising: a) providing first and second plates;b) coupling the first and second plates together separately from the bone; and thenc) securing the coupled plates to the bone at the bone surface with a bone screw that has a head and shaft, the head passing through the first plate and seating on the second plate above the bone surface, and the shaft having bone engaging threads that engage the bone under the bone surface. 8. A method of coupling a plurality of bone plates to a bone having a bone surface, comprising: providing a selection of first-type of plate and second-type of plate, the selection of the first-type and second-type of plates including discrete sizes of at least one of the respective types of plates;first coupling a selected first-type and second-type of plates together separately from the bone with a set screw such that they are securely longitudinally retained in tension, independently of the bone; and thensecuring the coupled plates to the bone at the bone surface with a bone screw, the bone screw having a head and a shaft, the head passing through the first-type of plate and seating on the second-type plate above the bone surface, and the shaft having bone engaging threads that engages the bone beneath the bone surface. 9. A method according to claim 8, wherein: axial advancement of the set screw into the plates in a first direction causes movement of the plates relative to each other in a direction perpendicular to the first direction. 10. A method according to claim 8, wherein: the first coupling includes inserting one end of the first-type of plate into a socket in the second-type of plate. 11. A method according to claim 8, wherein: after securing the coupled first-type and second-type plates to the bone, further coupling the plates together with an element that does not extend into bone. 12. A method according to claim 8, wherein: the further coupling prevents backout of the bone screw. 13. A method according to claim 8, wherein: said first-type plate has a stem portion and a head portion angled relative to said stem portion, said stem portion including a bone contacting side, an opposite upper side, a socket below said upper side and extending through said bone contacting side, a passing hole, a tapered eccentric set screw hole, and an integrated post, said passing hole extending through said upper side and into said socket and sized to permit passage of both the head and the shaft of the bone screw completely therethrough,said tapered eccentric screw hole in said upper side dimensioned to retain the head of the set screw,said integrated post extending into said socket from a direction of a said upper side toward said bone contacting side, andsaid second-type plate has an end portion receivable within said socket, said end portion including a bone screw hole, a threaded hole, and an upper recess, said bone screw hole permitting passage of the shaft of the bone screw but dimensioned to retain the head of the bone screw such that rotation of the bone screw causes the second plate to be clamped against the bone,said threaded hole including machine threads for engaging the shaft of the set screw, andsaid upper recess for receiving said post when said end portion of said first plate is received in said socket,wherein when said end of said second plate is received in said socket of said first plate and said post is received in said upper recess of said second plate, said bone screw hole is in alignment with said passing hole and said threaded holes is aligned with said tapered eccentric screw hole.
