Abstract
A backbone osteosynthesis system for anterior fixing comprising first and second arms, each capable of receiving bone screws and a longitudinal plate for rigidly linking the arms, the plate being in one single piece with the first arm. The system comprises a way to adjust the second arm in a longitudinal position on the plate.
Claims24
A spinal osteosynthesis system for anterior fixation, comprising first and second arms, which can each receive bone screws and a longitudinal plate which can rigidly link the arms, the plate being made in one piece with the first arm and means for adjusting a longitudinal position of the second arm on the plate said means including a vertebral screw for coupling said second arm to said plate.
A spinal plating system comprising:
- an elongated bone plate having a longitudinal axis and a bone screw receiving opening at a first end and a longitudinally extending slot at a second end;
- a bone screw slidingly engaging said slot;
- and
- an arm element slidably received on said plate adjacent said slot, said arm element having an opening thereon for receiving said bone screw engaging said slot, said arm element having a locking portion for lockingly engaging said bone plate to lock said arm element and said bone screw at a selected longitudinal location with respect to said slot.
A spinal osteosynthesis system for anterior fixation, comprising first and second arms, which can each receive bone screws and a longitudinal plate which can rigidly link the arms, the plate being made in one piece with the first arm and means for adjusting a longitudinal position of the second arm on the plate and further comprising at least one fixation screw which can be engaged in one of the bone screws associated with one of the arms in order to fix the arm to the bone screw.
A method for connecting two vertebra comprising:
- attaching a first part of a two piece first bone screw into a first vertebra, the first bone screw part having a head with a threaded bore;
- attaching a first part of a two piece second bone screw into a second vertebra, the second bone screw first part having a head with a threaded bore;
- and
- attaching an elongated bone plate having a longitudinal axis and a screw receiving opening for said first bone screw at a first end and a longitudinally extending slot at a second end for receiving said second bone screw to the first and second vertebra by placing said plate on said first and second bone screw first parts and attaching a clamping element to said first and second bone screws by inserting a threaded shank on clamping elements through said screw receiving opening and said slot in said plate, into said threaded bore in said bone screw heads and clamping said plate to said screw first parts.
