Abstract
A cement restrictor system is provided for making a cement plug within the medullary canal of a long bone. The system includes an inflatable body, a conduit having first and second ends that defines a fluid passage to and from the inflatable body, and a shield releasably securable to the conduit. In an exemplary method of making a cement plug with the system an obstruction, such as the shield, is placed in a medullary canal of a long bone beyond the isthmus of the long bone. The obstruction is held in place with the flatable body. A predetermined quantity of bone cement is poured into the medullary canal and localized by the obstruction. The bone cement is allowed to harden; and the conduit and inflatable body are removed from the bone.
