摘要： A method of repairing a fractured bone may include implanting a prosthetic stem into an intramedullary canal of the fractured bone. First and second bone segments of the fractured bone may be robotically machined to include first and second implant-facing surfaces that are substantially negatives of first and second surface portions of the first end of the prosthetic stem. The first and second tuberosities may be machined so that the first and second bone segments have first and second interlocking surfaces shaped to interlock with each other. During implantation, the first and second implant-facing surfaces are in contact with the first and second surface portions of the first end of the prosthetic stem, and the first interlocking surface interlocks with the second interlocking surface.

摘要： 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.

摘要： A stemless humeral shoulder assembly having a base member and an anchor advanceable into the base member. The base member can include a distal end that can be embedded in bone and a proximal end that can be disposed at a bone surface. The base member can also have a plurality of spaced apart arms projecting from the proximal end to the distal end. The anchor can project circumferentially into the arms and into a space between the arms. When the anchor is advanced into the base member, the anchor can be exposed between the arms. A recess can project distally from a proximal end of the anchor to within the base member. The recess can receive a mounting member of an anatomical or reverse joint interface.

摘要： A stemless humeral anchor (10) includes a first end (12) configured to be embedded in a proximal portion of a humerus and a second end (14); a mating portion (16) for an articular component; a transversely extending collar (20); and a rotation control feature (22, 22A) for resisting rotation when the stemless humeral anchor is implanted. A void filling protrusion (24) can extend circumferentially from rotation control feature and can include a porous shell (26), in which a void filling component (28) can be disposed. The rotation control feature can comprise arms. One or more arms (22A) can have a larger radial extent than the others (22). A prosthesis assembly includes a base member (104) that has a helical structure (224) and one or more pathways (300). The pathway is accessible from a proximal end and is directed distally through the helical structure. The pathway is located inward of an outer periphery of the helical structure. The pathway extends in a space between successive portions of the helical structure. The prosthesis assembly includes a locking device (108) that has a support member (132) and an arm (110) that projects away from the support member. The arm is disposed in the pathway when the support member is disposed adjacent to the proximal end of the base member. The arm is disposed through bone in the space between successive portions of the helical structure when the prosthesis assembly is implanted.

摘要： A stemless implant for shoulder arthroplasty includes a body having a proximal portion, distal portion, and an outer surface. A cylindrical extrusion is substantially perpendicular to and adjacent the proximal portion. At least a portion of the outer surface is configured to contact bone, the outer bone contacting surface comprising a concave taper. The stemless implant can be sized and shaped for insertion into a metaphysis of a humerus bone without penetrating a diaphysis of the humerus bone. The implant optionally comprises a medial fin, a lateral fin, an anterior fin, and a posterior fin. The medial fin and lateral fin may be thicker than the anterior fin. The fins may taper from the proximal portion to the distal portion.

摘要： 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.

摘要： A method of implanting a humeral component includes accessing a humerus and resecting a head portion of the humerus to form a resected surface. The method further includes selecting a first combination sizer and guide device having an outer surface sized complementary to a desired implant head size, positioning the selected first combination sizer and guide device on the resected surface, guiding placement of a guide pin in the humerus with the first combination sizer and guide device, guiding a reamer with the placed guide pin to form a reamed cavity in the humerus, positioning an anchoring portion of a humeral implant base portion in the reamed cavity, positioning the first combination sizer and guide device on the base portion, removing the first combination sizer and guide device from the base portion, and positioning an implant head on the base portion.
