The present invention relates to a bone plating system and method for fracture fixation of bone. The bone plating system includes a bone plate, at least one locking screw, and at least one non-locking screw. The bone plate has locking holes with threads and non-locking holes. The locking screws have
The present invention relates to a bone plating system and method for fracture fixation of bone. The bone plating system includes a bone plate, at least one locking screw, and at least one non-locking screw. The bone plate has locking holes with threads and non-locking holes. The locking screws have a shaft with a thread for engaging bone and a head with a thread configured and dimensioned to mate with the thread of the locking holes. The non-locking screws have a thread for engaging bone and a non-threaded head. Both the locking and non-locking screws remain seated in their respective holes for substantially as long as the bone plate is implanted. The non-locking screws compress the bone plate against the bone and hold fracture reduction while the locking screws are secured to the plate at a fixed angular relationship. The mixed fixation achieved by this bone plating system and method is particularly useful for treatment of per-articular fractures.

A device as recited in claim 1, wherein said suction device is a device that creates a partial vacuum. 10. A method for ophthalmic laser surgery which comprises the steps of: providing a lens having a lens member, said lens member formed with an anterior surface and a contact surface, said contact surface being opposed to said anterior surface, said lens having a skirt surrounding said contact surface and extending outwardly therefrom to define a recessed chamber therebetween, said skirt having a sealing surface, and said lens further having a suction device in fluid communication with said recessed chamber for creating a partial vacuum therein between said contact surface and a cornea; placing said sealing surface of said skirt against the exterior surface of an eye; creating a partial vacuum in said recessed chamber with said suction device to draw the cornea into said recessed chamber and reconfigure the cornea against said contact surface; and passing a laser beam through said anterior surface and said contact surface and into the cornea to perform ophthalmic laser surgery. 11. A method as recited in claim 10 wherein said contact surface is substantially flat. 12. A method as recited in claim 10 wherein said contact surface is curved. 13. A method as recited in claim 10 wherein said sealing surface is concave extending into said recessed chamber and formed of a soft, medical grade plastic. 14. A method as recited in claim 10 wherein said contact surface is shaped to introduce less spherical aberration to said laser beam as said laser beam passes into the reconfigured cornea than is introduced into an identical laser beam passing into a cornea that is not reconfigured. 15. A method as recited in claim 10 wherein said lens member is transparent. 16. A method as recited in claim 10, wherein said suction device is selected from the group of suction devices consisting of: a vacuum pump, a syringe, and a device that creates a partial vacuum. 17. A method as recited in claim 10, wherein said suction device is a device that creates a partial vacuum. 18. A lens system for reconfiguring a cornea and holding the reconfigured cornea during a laser treatment, said system comprising: a lens member having an anterior surface and formed with a contact surface opposed to said anterior surface, said contact surface shaped to reconfigure the cornea; a skirt, said skirt having a sealing surface and said skirt surrounding said contact surface and projecting outwardly therefrom to define a recessed chamber therebetween, said recessed chamber having an opening; and a passageway positioned substantially adjacent to said contact surface, said passageway in fluid communication with said recessed chamber; and a suction device in fluid communication with said passageway for creating a partial vacuum in said recessed chamber to reconfigure the cornea against said contact surface when said cornea is placed over said opening of said recessed chamber. 19. A lens system as recited in claim 18 further comprising: a means for mounting said lens member and said skirt to a laser system. 20. A lens system as recited in claim 18 further comprising: a laser source for producing a laser beam, said laser source positioned to pass said laser beam through said lens member. 21. A lens system as recited in claim 18, wherein said suction device is selected from the group of suction devices consisting of: a vacuum pump, a syringe, and a device that creates a partial vacuum. 22. A lens system as recited in claim 18, wherein said suction device is a device that creates a partial vacuum. 23. A lens system for contacting a cornea of an eye and holding the contacted cornea during a laser treatment, said system comprising: a lens member having an anterior surface and formed with a contact surface opposed to said anterior surface, said contact surface shaped to contact the cornea; a skirt, said skirt surrounding said contact surface and projecting outwardly therefrom to define a recessed chamber therebetween; and a plurality of projections, each said projection extending from said skirt for contact with the exterior surface of the eye, wherein said projections prevent the cornea from moving relative to said lens member. 24. A lens system as recited in claim 23 further comprising: a means for mounting said lens member and said skirt to a laser system. 25. A lens system as recited in claim 23 further comprising: a laser source for producing a laser beam, said laser source positioned to pass said laser beam through said lens member. 26. A device for contacting the anterior surface of a cornea of an eye for ophthalmic laser surgery which comprises: an optical element having an anterior side and a posterior side, said posterior side being formed with a recessed chamber and having a contact surface and a sealing surface, such that the cornea is contacted against said contact surface when said sealing surface is pressed against the exterior surface of the eye, wherein said sealing surface is formed of a soft, medical grade plastic material that conforms to the exterior surface of the eye to establish a seal with the exterior surface of the eye when said sealing surface is pressed against the exterior surface of the eye. 27. A device as recited in claim 26 wherein said contact surface is substantially flat. 28. A device as recited in claim 26 wherein said contact surface is curved. 29. A device as recited in claim 26 wherein said sealing surface is concave extending into said recessed chamber. 30. A device as recited in claim 26 further comprising a retainer ring, said optical element being mounted on said retainer ring and further, wherein said retainer ring is attached to a laser system. 31. A device as recited in claim 26 wherein said contact surface is transparent. 32. A method for ophthalmic laser surgery which comprises the steps of: providing a lens having a lens member, said lens member formed with an anterior surface and a contact surface, said contact surface being opposed to said anterior surface, said lens having a skirt surrounding said contact surface and extending outwardly therefrom to define a recessed chamber therebetween, said skirt having a sealing surface, such that a cornea is contacted against said contact surface when said sealing surface is pressed against the exterior surface of an eye, wherein said sealing surface is formed of a soft, medical grade plastic material that conforms to the exterior surface of the eye to establish a seal with the exterior surface of the eye when said sealing surface is pressed against the exterior surface of the eye; placing said sealing surface of said skirt against the exterior surface of the eye; pressing said sealing surface against the exterior surface of the eye, such that the cornea is contacted against the contact surface; passing a laser beam through said anterior surface and said contact surface and into the cornea to perform ophthalmic laser surgery. 33. A method as recited in claim 32 wherein said contact surface is substantially flat. 34. A method as recited in claim 32 wherein said contact surface is curved. 35. A method as recited in claim 32 wherein said sealing surface is concave extending into said recessed chamber. 36. A method as recited in claim 32 wherein said contact surface is shaped to introduce less spherical aberration to said laser beam as said laser beam passes into the contacted cornea than is introduced into an identical laser beam passing into a cornea that is not contacted. 37. A method as recited in claim 32 wherein said lens member is transparent.
