Embodiments described herein provide tools and methods for spinal fusion procedures. One embodiment of a tool can be a pedicle access tool (100) that performs the functions of targeting needle, cannula, tap and awl. The cannula of the tool can be used to guide various tools and bone graft or fusion promoting material to a surgical site for a spinal fusion procedure, such as a posterolateral procedure. In other embodiments, a k-wire can be used as the guide. The pedicle access tool comprises a cannula (102) with a tip (120) adapted to act as a bone awl, a threaded section (122) adapted to act as a bone tap, a detachable cannula handle (104), and a stylet (106) comprising a handle (138) detachably coupled to the cannula handle and a needle (140) passing through the cannula with a tip (142) that extends past the tip of the cannula. |
