Abstract: An orthopedic driver is provided that includes an elongate tubular body and an indicator assembly. The indicator assembly has a housing that has at least one opening and a visual indicator disposed in the at least one opening. The visual indicator is configured to be coupled with a guide pin such that lateral movement of the elongate tubular body relative to the guide pin causes the visual indicator to move between a flush or recessed configuration within the housing and an extended configuration. In the extended configuration, the visual indicator extends outward of an outer surface of the housing. The flush or recessed configuration corresponds to alignment of the guide pin relative to the elongate tubular body and the extended configuration corresponds to misalignment of the guide pin relative to the elongate tubular body.

Abstract: A prosthesis that mechanically couples with both cancellous bone and cortical bone of a glenoid includes a head portion comprising a rear surface and an articular surface, an anchor member, and a plurality of deformable fins extending radially outward from the anchor member. The anchor member includes a distal end and a proximal end connected to the rear surface of the head portion. The plurality of deformable fins extend radially outward from the anchor member and includes at least a first proximal fin adjacent to the rear surface of the head portion positioned to engage with the cortical bone. The anchor member may also include at least one distal fin located proximate the distal end of the anchor member positioned to engage with the cancellous bone.

Abstract: A system for securing a prosthesis in a bone includes a reference anchor for insertion into a cavity of a bone to define a reference point during prosthesis implantation, the reference anchor including a body having a mating feature and a gripping projection for engaging an inner surface of the bone cavity. The system also includes a stem having a terminal end adapted to mate with the engagement feature of the reference anchor such that the stem is disposed at a desired position relative to the reference point.

Abstract: Joint prostheses and associated methods that have a medialized center of rotation, inhibit subluxation of the implant while facilitating full range of motion and normal articular function, are able to be implanted using standard bone preparation techniques, and/or provide increased implant lifetime.

Abstract: A fracture fixation plate with cover sheath having a head element that is rigidly connected to a plate element in an upwardly angled direction. The head element is anatomically shaped and includes medial and lateral sheath recesses wherein non-threaded bone screw holes and a threaded sheath screw hole are located. Cylindrical head bone screws are inserted through the sheath recess and oriented at set angles allowing for bone fragment fixation and fracture reduction. Medial and lateral sheath elements are placed within the boundaries of their respective sheath recesses and are secured with a sheath screw. The sheath elements contact the heads of the inserted bone screws restricting and maintaining their implanted positions. Alternative sheath elements with outreaching medial, lateral and distal fragment capture flanges may also be utilized. The plate element includes at least one longitudinal slot with several bone screw holes for use with pivotable spherical headed bone screws.
