The present invention is directed towards a Jamshidi assembly which can be used for surgical procedures, such as inserting a pedicle screw within a patient. The Jamshidi assembly comprises an inner cannulated member sized and shaped to receive a sharp pointed medical device and slidably disposed within an outer sleeve member. When engaged with the inner cannulated member, the outer sleeve member is constructed to rotate and move about a longitudinal axis of the Jamshidi assembly. Coupled to the outer sleeve member is a working end adapted to contact and be driven into an anatomical structure, such as a vertebral body. Depending on the working end, configurations, such as threading may be formed within the anatomical structure.
