Surgical assembly and method for repairing depression fractures

A surgical method, comprising:

• forming a pilot hole through cortical bone that is located inferior to a depression fracture;
• accessing a depressed bone fragment of the depression fracture with a surgical assembly by locating a blunt tip of an obturator beneath the depressed bone fragment, the surgical assembly including a cannula positioned inside a joint and the obturator receivable through the cannula, wherein the cannula includes a distal end, and the blunt tip of the obturator and the distal end of the cannula are curved and extend along an axis that is transverse to a longitudinal axis of the surgical assembly;
• positioning the depressed bone fragment toward its original anatomical position using the blunt tip of the obturator to raise the depressed bone fragment toward the original anatomical position;
• removing the obturator from the cannula;
• inserting a delivery device in the cannula;
• injecting a liquid repair material through the cannula to the depression fracture with the delivery device to repair the depression fracture;
• and
• keeping the cannula inside the joint between the steps of removing the obturator from the cannula and injecting the liquid repair material through the cannula.
