configuration of texturing allows first rod band 45 and second rod band 105 to tighten around rods 20 or screws 15 held within their respective interior regions namely first rod position 80 and second rod position 125 these ridges and grooves are preferably positioned to provide a mating surface with the exterior surface of a rod 20 or screw 15 which may also have surface texturing 130 and which is placed within first rod position 80 and second rod position 125 surface texturing 130 therefore would tend to aid in preventing longitudinal motion of a rod 20 or screw 15 within first rod position 80 and or second rod position 125 surface texturing 130 however is considered optional and is not necessary for the proper functioning of connector 10 referring now to fig4 and 5 in a separate aspect of the invention a plurality of connectors 10 may be used along a length of rod 20 the adjustable nature of the connector 10 allows the connector to be moved along the length of rod 20 prior to advancing tightening screw 85 and interlocking the connector 10 to the rod 20 as shown in fig6 a pedicle screw of the prior art is illustrated such a pedicle screw includes a smooth shaft or shanked portion 19 that can easily be grasped by the connector 10 of the present invention in a separate aspect of the present invention a connector having two conical surfaces may be adapted to the end of a rod 20 as shown in fig7 12 more particularly rod 20 is manufactured with a conical surface forming an end of rod 20 for example in the case of the embodiment referred to.
