A cannula with a proximal end, a distal end and a lumen penetrating from the proximal end to the distal end. The cannula includes a shaft portion including a rear end and a front end, a tip portion coaxially extending from the front end of the shaft portion to the distal end of the cannula, and a cutting edge. A coupling portion, which is suitable for being connected to a surgical tool or instrument, is terminally arranged towards the proximal end of the cannula and extends to the rear end of the shaft portion. A removable obturator is insertable in the lumen. The obturator seals the lumen at the distal end of the cannula. A method for improved fracture fixation using the cannula, a method for intraoperative surgical decision making using the cannula and a method for irrigation of bone tissue and subsequent injection of bone cement using the cannula.
