The present invention provides a system for navigating to and providing treatment within bone, the system comprising: a trocar having a central channel and an opening at a distal tip of the trocar； a straight stylet configured to be installed in the trocar, the straight stylet comprising a sharp distal tip that is configured to extend beyond the opening at the distal tip of the trocar and to pierce an outer cortical bone region of the bone； a channeling instrument configured to be inserted through the trocar after removal of the straight stylet to create a predetermined-length linear path within a cancellous region of the bone toward a target treatment site； and a treatment device configured to provide a therapeutic treatment to the target treatment site.
