ABSTRACT:
Particulate bone is more easily and quickly guided into position for impaction into the site of a fusion mass by using a surgical funnel provided by an elongated, thin, flat base and a pair of thin, upstanding walls which extend along the elongated edges of the base to provide a chute. While the outlet of the funnel rests against the recipient site, particulate bond is incrementally pushed from the chute and tamped to build a fushion mass. By doing so, the particulate bone is much less likely to become contaminated by soft tissues. Preferably the reservoir provided by the upstanding walls is large enough to hold sufficient particulate bond to complete one side of a usual fusion mass so that the funnel can be left in position during that part of the surgical procedure. The funnel can be a single piece of metal or plastic.
