A glenoid implant may include an articulating surface, a bone contacting surface opposite the articulating surface, and at least one anchor. The bone contacting surface may include a first portion with a first convexity configured to contact a first portion of the glenoid and a second portion with a second convexity configured to contact a second portion of the glenoid. The first convexity may be different than the second convexity. The implant may include a bearing component defining the articulating surface and an augment component defining at least a portion of the bone contacting surface. Anchors or protrusions may extend from the bone contacting surface. The anchors may include a substantially planar surface.

Augmented glenoid design

A reaming device for preparing a glenoid of a patient may include a base configured for mounting to bone and an oscillatory rasp configured to be translatable in a proximal-distal direction relative to the base while the base is coupled to the glenoid of the patient.

Reamer for augmented glenoid implant

A glenoid implant system may include a main body formed of a polymer, a base, and an anchor formed of metal. The main body may define an articulating surface and an opposite bone-contacting surface. The base may be formed in the bone-contacting surface of the main body, the base including a hole formed therein. The anchor may have a main section and a threaded post extending from the main section. The anchor may include a plurality of ribs extending in a longitudinal direction of the main section, the plurality of ribs being spaced apart from one another in a circumferential direction of the main section. The anchor may further include a plurality of wedges disposed on a base of the anchor, the plurality of wedges adapted to contact the base formed in the bone-contacting surface of the main body when the threaded post is received within the threaded hole.

Glenoid implant with additively manufactured fixation posts

Illustrative embodiments of orthopedic implants and methods for surgically repairing hammertoe are disclosed. According to at least one illustrative embodiment, an orthopedic implant includes a proximal segment comprising a number of spring arms forming an anchored barb at a first end of the implant, a distal segment extending between the proximal segment and a second end of the implant, and a central segment disposed between the proximal and distal segment.

Orthopedic implant and methods of implanting and removing same

A prosthetic glenoid implant may include a polymer bearing component, a metal base component, and a plurality of fixation members. The bearing component may have a first surface adapted to articulate with a humeral head, and an opposing second surface including a first mating feature. The base component may have a first surface and a bone-contacting surface, the first surface having a second mating feature adapted to engage the first mating feature, the bone-contacting surface adapted to contact the native glenoid. The base component may define a plurality of apertures. The fixation members may each have a head and a threaded shaft adapted to pass through a corresponding one of the plurality of apertures, the head of each fixation member adapted to be positioned within a recess defined between the base component and the bearing component in an assembled condition of the prosthetic glenoid implant.

Keeled glenoid implant

According to one aspect of the disclosure, a glenoid implant for replacing a native glenoid includes an articulating surface configured to articulate with respect to a humeral head. A bone-facing surface may be opposite the articulating surface, the bone-facing surface having a first area configured to contact a paleoglenoid of the native glenoid. An augment portion may be coupled to the bone-facing surface, the augment portion being configured to contact a neoglenoid of the native glenoid. The augment portion may be transitionable between a first configuration in which the augment portion has a first convexity and a second configuration in which the augment portion has a second convexity different than the first convexity.

Truss glenoid augment

A surgical instrument for use in sizing a bone staple implant for implantation into a patient's bone is disclosed. The surgical instrument includes an elongated body having a first longitudinal end and a second longitudinal end. A first sizing plate is attached to and extending outwardly from the first longitudinal end, and a second sizing plate is attached to and extending outwardly from the second longitudinal end. The first sizing plate includes a first visible marking that identifies a width of a first bone staple implant, and the second sizing plate includes a second visible marking that identifies a width of a second bone staple implant. A system and a method for sizing a bone staple implant for implantation into a patient's bone are also disclosed.

Surgical instrument and method for use in sizing fixation implants

A surgical spreader assembly for use in implanting staples and other implants in a patient is disclosed. The spreader assembly may be included a kit with a number of other surgical instruments and the staples for implantation in the patient.
