Abstract
A nail cap cannula for directing a nail cap useable with an intramedullary nail system including an intramedullary nail and a targeting guide.
Claims18
A nail cap cannula system comprising:
- an intramedullary nail having an external surface including an external mating feature adjacent to a first end of the nail;
- a nail cap cannula having a substantially hollow body portion including a first end and a second end with a bore extending therebetween, the bore having an inner dimension sized to receive at least a portion of the intramedullary nail, the first end including an internal surface having an internal mating feature configured to mate with the external mating feature of the intramedullary nail;
- and
- a targeting guide having a proximal handle portion and a distal end, the distal end having an outer dimension that is smaller than the inner dimension of said bore of said nail cap cannula, wherein the distal end of the targeting guide is receivable within the hollow body portion of said nail cap cannula;
- wherein, when the intramedullary nail, the nail cap cannula and the targeting guide are assembled, the nail cap cannula moves between a disengaged position relative to the intramedullary nail, in which the internal mating feature of the nail cap cannula is disengaged from the external mating feature of the intramedullary nail, and an engaged position relative to the intramedullary nail, in which the internal mating feature of the nail cap cannula is engaged with the external mating feature of the intramedullary nail.
