1. A guidewire system for spine surgeries comprising:
a first guidewire portion including
an elongate first guidewire body having a distal end, a proximal end, and a longitudinal axis extending between the distal and proximal ends,
a threaded male fastener at the distal end of the first guidewire body and extending distally therefrom, the threaded male fastener being configured to fasten to a vertebra of a spine of a subject, and
a threaded female coupler extending distally from the proximal end of the first guidewire body and defining a threaded opening; and
a second guidewire portion including
an elongate second guidewire body having a distal end, a proximal end, and a longitudinal axis extending between the distal and proximal ends, and
a threaded male coupler at the distal end of the second guidewire body and extending distally therefrom, the threaded male coupler being adapted to thread into the threaded female coupler of the first guidewire portion to fasten the second guidewire portion to the first guidewire portion to form an elongate guidewire,
wherein the first guidewire portion is identical to the second guidewire portion.
