Abstract
A device for plugging the medullary canal in joint replacement surgery which prevents the cement used for fixation from extending beyond that point where it is useful and which also creates a closed space to facilitate more complete cement filling of the femoral canal or other boney cavities is disclosed. The device is comprised of a tapered cylindrical plug which is threadedly engaged to a long flexible shaft capable of being inserted into the medullary canal. The shaft is disengaged from the plug after the plug is lodged at the appropriate place in the canal. The plug is made of a bio-compatible material.
