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.

A knee joint prosthesis is disclosed. The knee joint prosthesis can include a tibial baseplate, a tibial insert, and a spine. The tibial baseplate can include a tibial plateau, having a proximal surface and an opposing distal surface, and a tibial stem extending from the distal surface of the tibial plateau. The tibial insert can be located on the proximal surface of the tibial plateau and can include an aperture. The spine can extend through the aperture of the tibial insert and into a cavity of the tibial stem, from the proximal surface of the tibial plateau. The spine can be rotatable with respect to the tibial baseplate and the tibial insert. The knee joint prosthesis can further include a femoral component including a posteriorly-located femoral cam. The posteriorly-located femoral cam can engage the spine during movement of the knee joint prosthesis.

Apparatus and methods of protecting modular implant connection portions are provided. A guard includes an outer sidewall and an inner sidewall defining a cavity that covers a modular implant connection portion. The modular implant connection covered with the guard can facilitate test-fitting of other modular implant components and allows reaming of the tissue around the guard.

A two piece humeral component for use in joint arthroplasty which is adapted to be implanted into a joint and engaged by a socket component of the joint. The joint component includes a body having a first articulating surface and a second medial surface opposite the first articulating surface. The first articulating surface is adapted to be engaged by the socket and the second medial surface is adapted to be secured to mounting portion. The mounting portion has a first surface and a second medial surface. The first surface is adapted to be fixably engaged to the second mounting portion of the humeral component. The second medial surface is adapted to be secured to the humerus. A peg which has a first end adapted to engage a cavity found in the humerus is disposed on the mounting portion's second medial surface.

Shoulder joint implants are disclosed herein for use in shoulder reconstruction that are configured to facilitate the inclusion a central bone screw for augmented bone fixation. The implant can include a baseplate (or metaglene) configured to secure a glenosphere or other prosthetic component to the glenoid. To facilitate lateral or proximal insertion of a central bone screw through the implant, a throughbore defined along the central axis of the metaglene can be widened to accommodate the maximum diameter of the screw. To enable fixation of the glenosphere to the metaglene, a collet can be configured to engage the smaller diameter of a glenosphere coupling element and inserted into the central throughbore. The collet and the bone screw can be separate parts, thereby making insertion of the bone screw optional. Alternatively, the collet and bone screw can be integrated together to form a unitary construct.

A device for containing bone graft material includes a mesh outer sleeve extending longitudinally from a proximal end to a distal end and sized and shaped to correspond to a profile of an outer surface of a target bone. The outer sleeve includes a longitudinal slot extending along a length thereof. The device also includes a mesh inner sleeve connected to an interior surface of the outer sleeve via at least one strut so that a bone graft collecting space is defined therebetween. The inner sleeve is sized and shaped to correspond to a profile of a medullary canal of the target bone. In addition, the device includes an interstitial mesh extending radially away from an exterior surface of the inner sleeve toward an interior surface of the outer sleeve to hold graft material in the bone graft collecting space.

Apparatus and methods of protecting modular implant connection portions are provided. A guard includes an outer sidewall and an inner sidewall defining a cavity that covers a modular implant connection portion. The modular implant connection covered with the guard can facilitate test-fitting of other modular implant components and allows reaming of the tissue around the guard.

An orthopaedic assembly. The orthopaedic assembly includes a first member adapted to be coupled to a bone and an adjustable connector assembly including an adjuster having a threaded end and a tapered end. The assembly also includes an articulation component including a bearing surface and adapted to be coupled to the tapered end of the adjustable connector assembly. The threaded end is adapted to engage the fixation plate.

Systems, devices, and methods are provided for orthopedic implants. The implants may include a base member, such as an acetabular shell or an augment, that is configured to couple with an augment, flange cup, mounting member, or any other suitable orthopedic attachment. Mounting members include, for example, flanges, blades, hooks, and plates. In some embodiments, the orthopedic attachments may be adjustably positionable about the base member or other attachments, thereby providing modularity for assembling and implanting the device, and various securing and/or locking mechanisms may be used between the components of the implant.
