A system includes: a cannula and curved stylet each including a pre-curved distal end portion； a straight channeling stylet； and a radiofrequency ("RF") energy device. The cannula includes an internal passageway and a first alignment member, with which a second alignment member of the curved stylet is aligned to align the distal end portions. The curved cannula and curved stylet form a curved path toward a target treatment site within a cancellous bone region. The straight channeling stylet is inserted within the internal passageway upon removal of the curved stylet. A distal end portion of the straight channeling stylet advances out of an open distal tip of the cannula to form a linear path beyond the curved path. The RF energy device is inserted within the internal passageway upon removal of the straight channeling stylet, and heats the target treatment site to denervate a nerve within the bone.
