Abstract
A surgical implant with recesses adapted to capture fixation medium that extravasates during implantation. The implant includes an elongated stem having a distal tip configured for insertion into an implant receiving area of a patient. A collar having recesses for capturing extravasating fixation medium is attached on the stem. The collar can be fixed to the stem by a separable collar-engagement feature or the collar can be fixed to the stem via structures on the stem.
Claims20
A method of using an implant to collect excess fixation medium extravasating from an implant receiving area during introduction of the implant, the method comprising:
- a. introducing the implant into the implant receiving area, wherein the implant includes
- an elongated stem having a distal tip, a proximate end opposite the distal tip, and at least one flange between the distal tip and proximate tip;
- a collar having a proximate end, a distal end opposite the proximate end, an exterior surface extending therebetween, a distal surface located adjacent the distal end and configured to abut a resected bone located adjacent the implant receiving area, at least one recess extending from the distal surface into the collar and configured to receive extravasating fixation medium, and an inner through bore extending between the proximate and distal ends of the collar and having at least one interior thread located on at least a portion of the inner through bore, wherein the at least one interior thread is sized and shaped to receive the at least one flange and lock the at least one flange in place;
- and
- b. contacting the distal surface to the extravasating fixation medium such that the at least one recess receives excess extravasating fixation medium therein.
A method of using an implant to collect excess fixation medium extravasating from an implant receiving area during introduction of the implant, the method comprising:
- a. assembling the implant, wherein the implant includes
- an elongated stem having a distal tip, a proximate end opposite the distal tip, and at least one flange between the distal tip and proximate tip;
- a collar having a proximate end, a distal end opposite the proximate end, an exterior surface extending therebetween, a distal surface located adjacent the distal end and configured to abut a resected bone located adjacent the implant receiving area, at least one recess extending from the distal surface into the collar and configured to receive extravasating fixation medium, and an inner through bore extending between the proximate and distal ends of the collar and having at least one interior thread located on at least a portion of the inner through bore, wherein the at least one interior thread is sized and shaped to receive the at least one flange and lock the at least one flange in place;
- b. introducing the implant into the implant receiving area;
- and
- c. contacting the distal surface to the extravasating fixation medium such that the at least one recess receives excess extravasating fixation medium therein;
- wherein the implant assembling step includes introducing the collar over the stem, translating the collar along the stem until the collar reaches the at least one flange of the stem, and then rotatably engaging the at least one interior thread of the collar with the at least one flange of the elongated stem.
A surgical implant, the implant comprising:
- an elongated stem having a distal tip, a proximate end opposite the distal tip, and at one least connection element between the distal tip and proximate tip;
- and
- a collar having a proximate end, a distal end opposite the proximate end, an exterior surface extending therebetween, a distal surface located adjacent the distal end, at least one recess extending from the distal surface into the collar, and an inner through bore extending between the proximate and distal ends of the collar and having at least one connection receiving element that is sized and shaped to receive the at least one connection element and lock the at least one connection element in place.
