Devices and methods for inserting bone cement into a patient during a surgical procedure. The methods may include inserting a tip of a nozzle at the desired location in the patient, such as an opening formed in a bone. An enlarged radial member may be positioned against the bone and covers the opening. Cement is moved through the nozzle and into the opening. The member may prevent escape of the cement from the opening. The nozzle may also be configured to facilitate insertion of the cement at the desired location within the patient.
