Abstract
A method for manipulating a vertebra includes connecting a first bone anchor to a first vertebra, connecting a second bone anchor to a second bone anchor, positioning a spinal rod in a receiving member of the first bone anchor and in a receiving member of the second bone anchor, connecting a first instrument to the receiving member of the first bone anchor, and manipulating the first instrument to rotate first bone anchor and the first vertebra relative to the second vertebra.
Claims20
A system for manipulating one or more vertebra, the system comprising:
- a first instrument having a distal end configured to engage a first bone anchor connected to a first vertebra,
- a second instrument having a distal end configured to engage a second bone anchor connected to a second vertebra, and
- a connector being configured to connect the first instrument and the second instrument through a first receiving element configured to receive the first instrument and a second receiving element configured to receive the second instrument, the connector having first and second arms pivotally coupled to one another at first ends thereof such that the first and second arms pivot between an open position and a closed position, the first and second receiving elements disengaged from the first and second instruments in the open position, and the first and second receiving elements engaging and permitting motion of the first and second instruments relative to the first and second receiving members in the closed position.
A system for manipulating one or more vertebra, the system comprising:
- a first instrument having a distal end configured to engage a first bone anchor connected to a first vertebra,
- a second instrument having a distal end configured to engage a second bone anchor connected to a second vertebra, and
- a connector being configured to connect the first instrument and the second instrument, the connector having first and second arms substantially extending along first and second axes and each having first and second ends, the connector having first and second receiving elements, each of the first and second receiving elements being configured to receive one of the first and second instruments, the first and second receiving elements being disposed between the first and second arms, and one of the first or second receiving elements being axially translatable along one of the first or second arms such that a position of the first or second receiving element along the first or second arm is adjustable relative to the other of the first or second receiving element.
