Abstract: Disclosed herein is a toe implant for replacing a portion of a human toe joint, as well as a related kit, surgical method, and method of manufacturing. Specifically, the toe implant may include a bearing member having a curved interface surface and a fixation member coupled to the bearing member. The fixation member may include a first portion having a non-porous barrier, and a tapered second portion.

Abstract: A humeral implant system, for example, includes an implant and a cutting guide system. The implant is a spherical wedge having an elongated curved upper surface having a first edge and a spaced apart second edge, a first surface having a curved upper edge joined to the first edge of the elongated curved upper surface, and a second surface having a curved upper edge joined to the second edge of the elongated curved upper surface. A lower edge of the first surface is joined to a lower edge of the second surface. The first surface and the second surface are disposed at an angle. The cutting system has a body having a first guide and a second guide for resecting a cutout in a humeral head, in which the cutout has a first surface and a second surface corresponding to the first surface and the second surface of the implant.

Abstract: A glenoid implant system, for example, includes a glenoid implant and a glenoid cutting guide. The glenoid implant includes a body having a concave surface with a first curved edge portion and a second curved edge portion, and an attachment surface having a concave edge portion joined to the second curved edge portion of the concave surface. The concave surface and the attachment surface are disposed at an angle. The glenoid cutting guide includes a body having a convex surface engageable with a surface of a glenoid cavity and a cutting guide surface for resecting a cutout in a glenoid cavity, the cutout having a curved edge portion corresponding to the second curved edge portion of the glenoid implant.

Abstract: An orthopedic reamer cutting tool is disclosed that incorporates a second material such as graphene having an increased coefficient of thermal conductivity to remove heat generated at the tissue cutting surface during use. The reamer is constructed having a hemispherical cutting shell that extends from an equatorial base to an apex at a distal end. A plurality of cutting teeth, each having a tissue cutting surface, extend from the exterior of the cutting shell. A reamer driver interface may be positioned spanning the diameter of the reamer base. The second material, having increased thermal conductivity, may be applied to the interior and/or exterior shell surfaces. In addition, the second material may be incorporated within the shell or the driver interface.

Abstract: An orthopedic impactor device for positioning an orthopedic prosthetic cup implant during a hip replacement surgery is described. The impactor comprises a distal prosthetic cup engagement portion which is separated from a proximal strike plate by an elongated housing and handle. The housing has a length that extends from a proximal housing portion to a distal housing end with an intermediate housing section therebetween. The intermediate housing section comprises spaced right and left side walls that extend upwardly from a bottom wall to an upper opening. A drive train, comprising a connection rod connectable to an orthopedic prosthetic cup, at least partially resides within the elongated housing. The drive train comprises a linkage sub-assembly that transfers rotational movement of a shaft located at the drive shaft proximal end to the connection rod.

Abstract: A prosthetic glenoid component for replicating the behavior of a patient's natural glenoid includes a rim that replicates the patient's natural glenoid labrum.

Abstract: An assembly tool for assembling components of an implant can include a finger assembly, a handle assembly, and a crossbar assembly. The finger assembly can include first and second fingers oriented parallel to each other, and sized and shaped to releasably engage first and second components of the implant during assembly. The handle assembly can include first and second handles pivotally connected to each other and configured to control movement of the first and second fingers. The crossbar assembly can be configured to maintain the first and second fingers substantially parallel to each other during movement of the first and second fingers. The assembly tool can be used for assembling a bearing assembly to an ulnar component of an elbow prosthesis.
