A glenosphere includes a body and a flange. The body includes a first body surface and a spherical second body surface, and includes an engagement feature to engage with an attachment structure attachable to a bone. The flange extends radially outward from the body and includes a first flange surface contiguous with a first body surface and a second flange surface contiguous with the second body surface. The flange has a flange length extending from a first end and a second end such that an angle defined by a first line from a center of the body to the first end and a second line from the center of the body to the second end is less than 180 degrees.

A shoulder implant system includes a humeral stem implant, a humeral neck implant component, a humeral head implant component, and a glenoid implant. The humeral stem implant has a fin coupled to an exterior surface thereof that is inwardly tapered at an angle relative to vertical. At least a portion of the fin forms a wedge that directly engages and compacts cancellous bone during installation of the humeral stem implant. The humeral neck implant component is configured to be coupled with the humeral stem implant. The humeral head implant component is configured to be coupled to the humeral stem implant via the humeral neck implant component. The glenoid implant has a plurality of peripheral pegs. Each of the peripheral pegs has a plurality of sets of resilient lobes.

Shoulder implant components

An insert component includes an insert body and a cavity defined within the insert body. The insert body includes a first surface, a second surface spaced from the first surface, and a third surface. The second surface cooperates with the first surface to define at least one first channel configured to receive an engagement member. The third surface has a first and second surface end each extending from a perimeter of the first surface. A curved portion of the third surface between the first surface end and the second surface end extends into the insert body. The cavity includes a first cavity opening defined by the first surface. The cavity defines a first cavity region and a second cavity region each coextensive with a third cavity region. The first cavity region and second cavity region each have a cavity diameter greater than a diameter of a plate engagement member.

A method of performing joint arthroplasty includes accessing a surface on a bone and supporting a stop with the accessed surface. The method includes positioning an instrument at least partially within the stop, the instrument having a body and a punch, the punch including a portion thereof having a shape similar to a shape of a stem of an implant, and rotating the stop with respect to the accessed surface based upon an indicia on one of the body and the stop so as to position the punch rotationally with respect to the accessed surface at a first orientation. The method further includes moving the body axially with respect to the stop to form a cavity in the bone with the punch at the first rotational orientation, the formed cavity having a shape similar to the stem of the implant, and implanting the stem of the implant into the cavity.

Punch, implant and associated method

A glenoid component includes a laterally facing bearing surface configured to engage a bearing surface of an element associated with a humerus, and a stem portion extending medially away from the bearing surface. The stem portion is configured such that when implanted in a scapula the stem portion includes three cross-sections parallel to a medial lateral plane. The middle cross-section has a length in the medial-lateral direction which is shorter than the lengths of the other two cross-sections in the medial lateral direction.

Glenoid component for shoulder arthroplasty

A glenosphere includes a body, a first surface, and a cavity defined with the body. The body defines a center and an engagement axis, the engagement axis spaced by an offset from the center. The first surface includes a first rim positioned radially outward from a second rim, a base surface portion, and a hood surface portion extending from the base surface portion and oriented at an obtuse angle relative to the base surface portion. The body defines a hood portion extending from the hood surface portion to a plane including the base surface portion. The cavity has a perimeter defined by the second rim, and includes a first cavity portion configured to receive an attachment structure attachable to a bone, and a second cavity portion configured to engage an engagement member of the attachment structure and oriented along the engagement axis.

A method of performing joint arthroplasty includes preparing a flat surface on a long bone, providing an instrument having a body and a punch extending from the body, the punch including a portion thereof having a shape similar to a stem of an implant, positioning a stop on the flat surface, rotating the stop with respect to the surface of the long bone based upon an indicia on one of the body and the stop so as to position the punch rotationally with respect to the surface to a desired orientation when the instrument is at least partially inserted into the stop, using the instrument to form a cavity in the long bone with the punch at the desired rotational orientation with the instrument inserted at least partially within the stop, the cavity having a shape similar to the stem of the implant, and implanting the stem into the cavity.

A method of making a glenoid component for shoulder arthroplasty includes obtaining a model of a glenoid vault morphology normalized from a population of a plurality of scapulae, the model being defined by a plurality of mutually parallel, triangular cross-sections, and producing a stem portion of the glenoid component based on the model.

A kit for use in performing joint arthroplasty on a head of a long bone is disclosed. The kit includes: a first implant including a first implant articulating surface and an opposed first implant mounting surface having a first implant location feature; and an instrument for preparing a cavity in the head of the long bone. The instrument includes a body and a punch extending from the body. The punch includes a portion thereof having a shape similar to the first implant location surface of the implant. A method for providing joint arthroplasty is also disclosed.

A glenosphere includes a body, a first surface, a second surface, a cavity defined within the body, and a plurality of channels. The body defines a central axis passing through the body. The first surface includes a first rim and a second rim. The first rim is positioned radially outward from the second rim relative to the central axis. The second surface extends from the first rim of the first surface. The second surface has a convex shape. The cavity has a perimeter defined by the second rim and is configured to receive an attachment structure attachable to a bone. The plurality of channels extend from the first surface through the body to the second surface. Each channel defines a first opening positioned on the first surface between the first rim and the second rim and defines a second opening positioned on the second surface. Each channel is configured to receive a bone fixation member configured to secure the glenosphere to the bone.

Glenosphere with augmented fixation and related methods

A joint prosthesis system, specifically a shoulder prosthesis, for shoulder replacement, revision and repair. The implants provide fixation into the best bone available to a surgeon. The implants are used in a superior-inferior and anterior-posterior construct forming a type of cross or X-shape. The implants allow for interchangeability of the articulating component as well as rotational orientation. The systems will allow for augments to accommodate bone loss. The implants may allow for additional security using screws or anchors inserted into the scapula.
