Methods of employing bone defect filling, e.g., orthopedic cements, in conjunction with hard tissue securing devices, e.g., screws, plates or rods, are provided. A feature of the subject methods is that the cement is introduced to a target bone site through a passageway of the securing device while a vibratory force is applied to the securing device. Also provided are systems and kits that find use in practicing the subject methods. The subject methods, devices and systems find use in a variety of different applications.

1. A method of introducing an orthopedic cement composition to a target bone site, said method comprising: implanting a hard tissue securing device at said target bone site, wherein said securing device comprises a passageway, wherein the hard tissue securing device is selected from the group consisting of a screw, plate, rod and nail;associating a cement delivery element with said passageway;delivering a cement composition through said cement delivery element to said passageway and to said target bone site while a vibratory force is applied to said securing device in a manner such that penetration of said cement into said target bone site is controlled without use of substantial pressure,wherein penetration of said cement into said cancellous bone stops substantially simultaneously with cessation of said vibration; anddisassociating said cement delivery element from said passageway. 2. The method according to claim 1, wherein said securing device is screw. 3. The method according to claim 1, wherein said securing device is a plate. 4. The method according to claim 1, wherein said securing device is a nail. 5. The method according to claim 1, wherein said vibratory force has a frequency ranging from 0.1 to 100,000 Hz. 6. The method according to claim 1, wherein said cement has a specific gravity at 20° C. that is at least about 1.0. 7. The method according to claim 6, wherein said cement is calcium phosphate cement. 8. The method according to claim 1, wherein said cement is a polymeric cement. 9. The method according to claim 1, wherein said target bone site comprises a reduced fracture. 10. The method according to claim 9, wherein said method further comprises reducing a fracture at said target bone site. 11. The method according to claim 1, wherein said target bone site comprises cancellous bone. 12. The method according to claim 1, wherein said vibratory force is indirectly applied to said securing device. 13. The method according to claim 12, wherein said vibration is provided by applying vibratory force to said cement delivery element. 14. The method according to claim 1, wherein said method comprises: (a) reducing a fracture at said target bone site; and(b) stabilizing said reduced fracture by implanting said hard tissue securing device. 15. The method according to claim 1, wherein said target bone site is present in a human. 16. The method according to claim 1, wherein said passageway is a channel bounded on all sides, with an exit at the end of the securing device.
