摘要:
A device and method for coupling first and second elongate spinal fixation elements. The device includes first and second connector members, for receiving first and second elongate spinal fixation elements respectively. One or both connector members may include an engagement portion configured and dimensioned to provisionally receive an elongate fixation element with an interference fit. First and second connector members are coupled to a translation member, the translation member operatively associated with at least one connector member to provide for polyaxial movement. At least one locking member is provided to secure a received elongate spinal fixation element in the engagement portion and lock polyaxial movement of the at least one connector member. The translation member may have first and second portions which move relative to each other with translation movement, and a third locking member to lock the translation movement.
