A surgical system for securing a rod to two bone screws, each bone screw being secured to a different vertebra, said system comprising: a first bone screw, said first bone screw comprising a first slot having a slot width; a second bone screw, said second bone screw comprising a second slot; a first sleeve comprising a first channel, said first sleeve having a length longer than a length of the first bone screw, said first sleeve comprising a distal end at one end of the first sleeve and a proximal end at a second end of the first sleeve, said first channel being formed in an opening of a sleeve wall of the first sleeve and said first channel extending along at least a portion of the length of the first sleeve; a second sleeve, said second sleeve having a length longer than a length of the second bone screw, wherein said second sleeve is configured to be detachably coupled to the second bone screw; a rod, said rod having a width less than the slot width; wherein the distal end of the first sleeve is configured to be detachably coupled to the first bone screw, such that the proximal end of the first sleeve extends away from the first bone screw, the first channel is aligned with a first slot in the first bone screw, and the first bone screw and first sleeve are substantially coaxial, and wherein the distal end of the first sleeve is configured to be decoupled from the first bone screw, characterized in that the system further comprises at least one moveable member extending between the first sleeve and the first bone screw, the at least one moveable member being moveable between a first a position to couple the first sleeve and the first bone screw together and a second position that allows release of the first sleeve from the first bone screw. a first bone screw, said first bone screw comprising a first slot having a slot width; a second bone screw, said second bone screw comprising a second slot; a first sleeve comprising a first channel, said first sleeve having a length longer than a length of the first bone screw, said first sleeve comprising a distal end at one end of the first sleeve and a proximal end at a second end of the first sleeve, said first channel being formed in an opening of a sleeve wall of the first sleeve and said first channel extending along at least a portion of the length of the first sleeve; a second sleeve, said second sleeve having a length longer than a length of the second bone screw, wherein said second sleeve is configured to be detachably coupled to the second bone screw; a rod, said rod having a width less than the slot width; wherein the distal end of the first sleeve is configured to be detachably coupled to the first bone screw, such that the proximal end of the first sleeve extends away from the first bone screw, the first channel is aligned with a first slot in the first bone screw, and the first bone screw and first sleeve are substantially coaxial, and wherein the distal end of the first sleeve is configured to be decoupled from the first bone screw, characterized in that the system further comprises at least one moveable member extending between the first sleeve and the first bone screw, the at least one moveable member being moveable between a first a position to couple the first sleeve and the first bone screw together and a second position that allows release of the first sleeve from the first bone screw.
