1. A method, comprising:
releasably coupling distal ends of first and second arms of an instrument to respective vertebrae, wherein proximate ends of the first and second arms are rotatably coupled to a driving rod about an axis defined by a threaded portion of the driving rod, the second arm having a threaded collar coupled to the threaded portion of the driving rod in axial engagement with the second arm;
releasably connecting, by a releasable threaded connection, the threaded collar and the threaded portion of the driving rod, the releasable threaded connection allowing for non-threaded axial re-positioning of the second arm along the driving rod when the threaded connection between the threaded collar and the threaded portion of the driving rod is released, the releasable threaded connection comprising a cam lever mechanism; and
after releasably connecting, rotating the driving rod with the threaded portion of the driving rod coupled with the threaded collar which is connected to the threaded portion, to translate the second arm along the driving rod with respect to the first arm,
prior to releasably connecting, further comprising:
sliding the second arm along the driving rod with the threaded collar released from the threaded portion of the driving rod to position the second arm adjacent the respective vertebra.
