The instrument has a first state, in which the implant connection feature is in the unlocked state and the friction-reducing feature is in the disengaged state; a second state, in which the implant connection feature is in the locked state and the friction-reducing feature is in the engaged state; and a third state, in which the implant connection feature is in the locked state and the friction-reducing feature is in the disengaged state. Methods of apparatus assembly and surgery are disclosed.
