Morsellized bone allograft applicator device

A system for applying a bone graft material to a prosthetic hip joint through an opening in an implanted acetabular cup, comprising:

• a device including
• a hollow tube having a proximal end and a distal end, the hollow tube defining a cavity that is effective to contain a bone graft slurry;
• a plunger rod disposed and longitudinally displaceable within the hollow tube member, the plunger rod having a proximal end and a distal end;
• an actuation mechanism coupled to a proximal end of the plunger rod that is effective to selectively advance the distal end of the plunger rod in a distal direction so as to eject the bone graft slurry from the hollow tube;
• a nozzle having a proximal end and a distal end, the proximal end being removably and replaceably matable to the distal end of the hollow tube member;
• and
• an acetabular cup having an opening with a distal end and a proximal end, the distal end of the nozzle having a geometry that is effective to engage the proximal end of the opening in the implanted acetabular cup and apply the bone graft slurry to a location proximate a distal end of the opening for filling a void at a bone/cup interface after implantation of the cup.

A bone allograft system for an implanted prosthetic joint, comprising:

• a device including
• a hollow tube member having a proximal end and a distal end, the tube member having a cavity that is effective to contain a bone graft slurry;
• an actuation mechanism coupled to the hollow tube member that is effective to selectively discharge the bone graft slurry from the tube member;
• a plurality of nozzles, each of which has a proximal end that is removably and replaceably matable to the distal end of the tube member and a distal end;
• and
• a plurality of prosthetic components each having at least one aperture formed therein for engaging a corresponding one of the plurality of nozzle distal ends to fill a void at an interface of bone and a respective one of the plurality of prosthetic components.
