Abstract: An apparatus including a humeral tray (120) configured to be mounted to a proximal end of a humeral stem (100), and an insert (130) positioned on an outer surface of the humeral tray configured to articulate with a glenosphere (110); wherein the insert is not attached to the humeral tray such that the insert can articulate and move relative to the humeral tray.

Abstract: This disclosure includes apparatus and methods to attach an orthopedic device to a bone. The method can comprise locating a baseplate on a glenoid of a patient, the base plate including at least a first fastener bore, creating a first post hole in the glenoid for locating a first fixation post, the first fixation post including a quasi-spherical head and a porous metal sleeve, and driving the first fixation post through the first fastener bore and into the first post hole. The porous metal sleeve can engage the first post hole and the quasi-spherical head can contact at least the first wall of the first fastener bore to removeably lock the quasi-spherical head to the baseplate. Driving the first fixation post can create an initial compression between the baseplate and the glenoid. The porous metal sleeve can receive bone ingrowth to maintain the initial compression.

Abstract: A reamer operably connected to a movable drive element by a translation assembly such that the movement of the movable drive element rotates the reamer. The reamer can be sized such that the reamer can be navigated through or around soft tissue to position the reamer adjacent the defect region and angled to align the reamer with a reamer axis perpendicular to the plane of the defect region. The translation assembly can be configured to translate rotation of the movable drive element to the reamer through an opening through or around the soft tissue. The translation assembly can permit axial reaming of the defect region when the perpendicular axis is obscured by soft tissue.

Abstract: A system can include a plurality of grouter devices configured to lodge in one or more focal defects located on a pair of articular surfaces; and a plurality of buffer devices configured to fill a space between the pair of articular surfaces; wherein the plurality of grouter devices and the plurality of buffer devices are sized and shaped such that a contact pressure between the pair of articular surfaces is diminished.

Abstract: A method for placing a first guide wire in a patient is disclosed. The method can include locating a model axis in a model and placing a second guide wire at the model axis, the model axis corresponding to an anatomical axis of an anatomical feature. The method can include coupling a guide plate to the second guide wire and the model. The method can include coupling an axis guide to the guide plate. The method can include decoupling the guide plate and the axis guide as an alignment unit from the second guide wire and coupling the guide plate and the axis guide as an alignment unit to the anatomical feature of the patient. The method can include using the alignment unit to place the first guide wire in the anatomical feature of the patient at the anatomical axis of the anatomical feature.

Abstract: The disclosure includes methods and systems for making orthopedic connections where there is unique adjustability to the connection. Illustratively, one embodiment provides a connecting assembly for connecting a plurality of orthopedic components. Such connecting assemblies can include a first orthopedic component that provides a female bore. Additionally, the assembly can include a second orthopedic component that can be or include a male-type connecting member that is positionable in the bore of the first orthopedic component. In one preferred form, the male-type connecting member will be a quasi-spherical member. The quasi-spherical member can include a textured outer surface, e.g., for contacting one or more walls or surfaces in the bore in a fashion that removably locks or helps to removably lock or fix the quasi-spherical member in the bore.

Abstract: Disclosed is a wedge for use during a reverse shoulder arthroplasty. The wedge can comprise a body having a proximal surface and a distal surface. The proximal surface and the distal surface can each extend from a distal end of the body to a proximal end of the body. The distal end can have a distal length and the proximal end can have a proximal length. The distal length can be shorter than the proximal length. The proximal surface can have a proximal curvature and the distal surface can have a distal curvature. The proximal curvature or the distal curvature can approximate a curvature of a deltoid muscle.

Abstract: A glenoid system (100) includes a baseplate (102) configured to attach to a glenoid cavity of a patient. In a primary configuration, a biocompatible plastic liner (332) can snap into a circumferential groove (120) on the baseplate, to attach to a lateral-facing surface (104) of the baseplate, at one or more locations around the groove. In a reverse configuration, a glenosphere (544, 644) can attach to an adapter (542, 642), which in turn can attach to the lateral-facing surface of the baseplate. The adapter can introduce lateral and/or angular offsets between the baseplate and the glenosphere, which can correct for unwanted offsets or inclinations. A middle peg extension (752) can screw onto a medial end of the middle peg (114), which can offer different combinations of peg length and peg material. The baseplates can be made available in various discrete sizes, each of which has the same distance between the middle peg and an inferior screw hole (112).
