1. An intramedullary nail for treating a bone fracture, the intramedullary nail comprising:
a proximal nail component defining a first longitudinal axis and a first coaxial channel;
a distal nail component defining a second longitudinal axis that is coaxial with the first longitudinal axis;
a rotatable shaft fixedly coupled to and extending proximally from the distal nail component, the rotatable shaft being slidably disposed within the first coaxial channel, the rotatable shaft being rotatable about the second longitudinal axis relative to the proximal nail component;
a first handle removably coupleable at a proximal end of the proximal nail component, the first handle being rotatable about the first longitudinal axis to drive longitudinal movement of the distal nail component relative to the proximal nail component while maintaining constant rotational positions of the proximal and distal nail components relative to the first and second longitudinal axes; and
a second handle removably coupleable at the proximal end of the proximal nail component, the second handle coupled to the rotatable shaft and being rotatable about the first longitudinal axis to drive rotation of the distal nail component about the second longitudinal axis while maintaining: (i) a constant rotational position of the proximal nail component relative to the first longitudinal axis and (ii) a constant overall longitudinal length of the intramedullary nail.
