Provided is a method for converting a modular anatomic shoulder implant to a modular reverse shoulder implant, wherein the modular anatomic shoulder implant and the modular reverse shoulder implant have novel configurations.

A method for securing a stemless humeral includes positioning the stemless humeral anchoring component to the humerus such that a lateral anchoring wing extends in a direction of a lateral side of the humerus into a lateral region and two medial anchoring wings face a medial side of the humerus in a medial region. The lateral region has a lower bone density relative to the medial region. The stemless humeral anchoring component is positioned eccentrically such that the anchoring stud and the two medial anchoring wings are anchored in the medial region. The stemless humeral anchoring component is secured in resected proximal epiphyseal and metaphyseal portions of the humerus without reaching a diaphyseal portion of the humerus.

A humeral anchor for a shoulder prosthesis is disclosed. The humeral anchor includes a distal portion configured to be anchored in a proximal region of a humerus and a proximal portion, the proximal portion including a proximal face, where the proximal face includes an engagement feature configured to directly couple to a reverse shoulder insert having a concave proximal portion, and wherein the proximal face is further configured to directly couple with an anatomical shoulder insert having a convex proximal portion.

An anatomy simulator can include a guide body having one or more faces. The anatomy simulator can include a first simulator socket forming a recess in a first face of the one or more faces. The first simulator socket can be configured to receive a first plate. The first simulator socket can include a first base portion. The anatomy simulator can include a bore extending from the base portion of the first simulator socket to an interior of the anatomy simulator. The bore can be configured to receive an alignment mechanism. The first base portion can be angled at a first angle with respect to the first face.

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.

The present disclosure provides a shoulder prosthesis. The shoulder prosthesis includes a glenoid component, a humeral component, and an articulation component. The glenoid component includes a glenoid body having a proximal side and a distal side, the distal side shaped to engage with a resected portion of a glenoid cavity. The humeral component includes a humeral body having a proximal side and a distal side, the distal side shaped to engage with a resected portion of a humerus. The articulation component is positionable between the proximal side of the glenoid component and the proximal side of the humeral component, the articulation component configured to be maintained between the glenoid and humeral components, after implantation, by at least one of a deltoid muscle and a rotator cuff.

A joint replacement system for repairing an articular surface of a first bone of a joint includes an anchor portion and an implant portion. The anchor portion includes an anchor to be secured to the bone, and an anchor fixation head including a bone-facing surface (BFS) extending radially outward from the anchor and an implant facing surface (IFS) extending from a periphery of the BFS. The implant portion is formed from a material (e.g., CoCr) more dense than the material of the anchor portion (e.g., Ti) and includes a fixation cavity to receive at least a portion of the anchor fixation head (AFH), the fixation cavity includes an anchor facing surface (AFS) configured to form a frictional connection with the IFS, and a load bearing surface having a contour for articulating against a cooperating articulating surface of a second bone of the joint.

A collar arranged to couple to a prosthetic component for implantation at the end of a long bone, the prosthetic component having a distal portion arranged to couple to the bone and a proximal neck portion arranged to couple to an articulation component. The collar comprises a plate including a neck hole to receive a neck portion, such that the collar can rotate about the neck portion. The collar further comprises a plurality of attachment portions for coupling the plate to bone fragments or soft tissues. The collar is lockable to the neck portion to prevent further rotation. A prosthesis comprising a combination of a collar, a prosthetic component and an articulation component, and a surgical method of using the collar are also disclosed.

A periprosthetic fracture repair solution that provides a variety of fracture fixation options should a fracture occur after total hip, knee, or especially a total shoulder arthroplasty, and provides associated methods and apparatus for application of provided fixation. The ability to pre-engineer fracture fixation contingent solutions into humeral components provides for a distinct clinical advantage in the planning and execution for periprosthetic fracture fixation. Said methods and apparatus include targeting devices which allow for intimate association of fixed angle locking screws in pre-drilled holes in an existing prosthetic or other components including additional fixation components. Such apparatus and methods further include the use of alignment devices and other components to allow for ease of repair of periprosthetic fractures utilizing the pre-engineered solutions. Such targeting devices are required in specific circumstances as the prosthetics may prevent x-ray imaging and consequently free hand alignment.

A medical implant for a human shoulder joint includes a first magnetic implant fixed to the non-articular surface of the greater tuberosity of the human shoulder joint, and a second magnetic implant fixed to an outer surface and underside of the acromion of the human shoulder joint. At least one of the first and second magnetic implants generates a magnetic field that urges the first and second magnetic implants away from each other and thereby distracts the humeral head of the human shoulder joint from the acromion.
