Abstract: A base member of a prosthetic stemless shoulder implant may include a proximal collar, a central anchor, and at least one peripheral anchor. The proximal collar may have a proximal surface and a distal bone-engaging surface opposite the proximal surface. The central anchor may extend distally from the bone-engaging surface and define an opening extending from the bone-engaging surface into the central anchor for receiving a humeral head component of the prosthetic stemless shoulder implant. The at least one peripheral anchor may be positioned radially outwardly of the central anchor and extend distally from the bone-engaging surface. The peripheral anchor may be frangibly connected to the proximal collar.

Abstract: A three-dimensional printing apparatus includes a base, a first build plate, and a second build plate. The base includes a build platform. The first build plate is attached to the base and is movable in vertical directions to a position spaced vertically from the build platform. The second build plate is supported by the first build plate such that the second build plate is spaced vertically from the first build plate. A plurality of objects is fabricated by the apparatus. A first object is fabricated on the first build plate. The first build plate is moved vertically. A second object is fabricated on the second build plate.

Abstract: Various apparatus and methods for implanting glenoid prostheses are disclosed. In various embodiments, a method for performing shoulder surgery can include guiding a guide pin into the glenoid surface along a reaming axis. A partial reaming guide can be placed in contact with the glenoid surface over the guide pin. A reamer can be guided over the guide pin to ream the glenoid surface. The reamer can be further advanced over the guide pin until the reamer contacts the partial reaming guide, whereby such contact limits reaming to only a portion of the glenoid surface.

Abstract: An inserter includes a first end, a second end, and a body extending between the first end and the second end. A first impacting surface is disposed at the first end, and a second impacting surface is disposed adjacent to the second end. An interface disposed at the second end and is configured to engage an implant. The first impacting surface is configured to direct a first impacting force along the body of the inserter in a first direction, and the second impacting surface is configured to direct a second impacting force along the body in a second direction that is different from the first direction. Methods of use also are disclosed.

Abstract: A method for separating an implant from a bone, includes interfacing a tool with an implant including a flange, the flange including a proximal surface and a distal surface, the distal surface bearing on or facing the bone, the flange including an aperture defined through the flange; inserting an elongate element through the aperture from the proximal surface to the distal surface and into the bone; and partially separating a bonding interface between the implant and the bone using the elongate element.

Abstract: An example system for designing a patient matched implant for an orthopedic joint repair surgical procedure includes a memory configured to store a model of a bone of a patient; and processing circuitry. The processing circuitry may be configured to: obtain the model of the bone of the patient; obtain a template model of an implant; determine a shape of a surface of the implant; determine a volume between the shape of the surface of the implant and a surface of the bone defined by the model of the bone; generate, based on the determined volume and the template model, a patient matched implant model; and output a file representing the patient matched implant model.

Abstract: Techniques and systems are described for planning shoulder stability enhancement surgeries. A computing system may determine a size of a predicted premorbid glenoid bone of the patient of a patient, a size of a Bankart lesion on a morbid glenoid bone of the patient, and a size of a geodesic surface on a 3-dimensional model of a predicted premorbid humerus of the patient. The geodesic surface is defined at least in part by a projected medial border of a Hill-Sachs lesion on a morbid humerus and a projected medial border of a footprint of a humeral head of the morbid humerus. The computing system may determine, based on the three areal sizes, whether bone loss of the patient involves joint engagement. The computing system may output an indication of whether a shoulder stability enhancement surgery that includes a bone graft is recommended for the patient.

Abstract: Provided is a method of manufacturing a prosthesis for a fractured long bone of a patient, the method including the steps of: A) providing data representative of the fractured long bone in a patient; B) based on said data, designing the prosthesis specifically to the patient, the prosthesis including a stem part that is configured to secure fragment(s) of the fractured long bone at chosen securing position(s) that will apply chosen mechanical stress onto the bone fragments and reduce the risk of osteonecrosis of the bone fragments.

Abstract: A joint prosthesis system includes a femoral component that has an articular side, a bone facing side, and medial and lateral condylar portions. The medial and lateral condylar portions at least partially define an intercondylar recess located therebetween and have a first concave surface extending in a mediolateral direction across the medial and lateral condylar portions. A first modular component has a second concave surface and is connectable to the femoral component such that, when the first modular component is connected to the femoral component, the first and second concave surfaces come together to form a transverse opening extending in the mediolateral direction. A first tibial assembly has a baseplate component and a head extending therefrom. The head defines an axle opening that extends therethrough. An axle is configured to be received within the transverse opening and axle opening so as to connect the tibial assembly to the femoral component.

Abstract: A glenoid component for coupling to a scapula of a subject includes a body. The body includes an articulation surface adapted to articulate with a humeral component, and the body further includes a distal surface adapted to face the glenoid of the scapula. The distal surface includes a base surface portion adapted to face a first portion of the glenoid. The distal surface further includes an augmented surface portion adapted to face a second portion of the glenoid. The base surface portion and the augmented surface portion define an obtuse angle therebetween.
