Abstract

A bone cutting device, such as a burr or saw blade, is irrigated to cool not only the bone cutting device itself, but also the bone of the subject on which a bone resection procedure is being performed. The bone cutting device can have one or more (e.g., a plurality of) internal flow channels that eject a cooling medium (e.g., water or an inert gas) from the bone cutting device. This emission of the cooling medium can not only flush bone chips from the resection site, thereby reducing frictional heating of the bone cutting device, but can also provide internal cooling to the bone cutting device while flowing through the one or more internal flow channels and also can cool the surface of the bone via conductive heat transfer (e.g., by the flow stream of the cooling medium impinging on the bone surface).

Abstract

Disclosed herein is an angled-wall femoral component (500) of a cam-post knee arthroplasty system for a posterior cruciate ligament (PCL)-substituting total knee arthroplasty (TKA) or revision TKA (rTKA) procedure, such as a cruciate substituting (CS), a bicruciate substituting (BCS), or posterior stabilized (PS) procedure. The angled- wall femoral component may include a femoral box (502) configured to receive the tibial post (110) of a corresponding tibial component (100). An anterior wall (508) of the femoral box is anteriorly angled and may include an anterior cam (561). The anterior wall is angled anteriorly to allow for clearance between an anterior side of the tibial post and the anterior wall, while allowing for operative engagement between the tibial post and the anterior cam during flexion and extension of the knee implanted with the femoral component.

Abstract

A broach tool for use in preparing an implantation site of a humeral head for implantation of a humeral prothesis therein includes a cylindrical sleeve that fits concentrically around a pin anchored in the implantation site, so that the broach is guided by the pin, and a broach head that has an outer profile formed on the portion thereof that faces towards and is driven against the implantation site. This outer profile engages against the implantation site to form alignment features, or slots, in the implantation site. These alignment features aid a surgeon in properly aligning a compactor with the implantation site after the pin has been removed, the compactor being used for forming the interior of the implantation site to allow the insertion of the humeral prosthesis therein.
